From June 2023, the Building (Scotland) Regulations 2004 have required at least one in ten parking spaces in new non-domestic buildings and major renovations with more than ten spaces to have access to an EV charge point socket. The Scottish Government’s ambition to phase out the need for new petrol and diesel cars and vans by 2030 is accelerating that requirement further. Workplace charging is now a standard feature of new Scottish commercial development and an increasingly common retrofit on existing office estates.
The fire safety frameworks of most Scottish office buildings have not kept pace.
Commercial EV charging introduces fire risks that are categorically different from the hazards that a standard office building fire risk assessment was designed to evaluate. A vehicle battery undergoing thermal runaway in an enclosed car park generates temperatures exceeding 1,000°C, produces toxic gases that accumulate rapidly in confined spaces, cannot be suppressed by conventional overhead sprinkler systems that cannot reach the battery pack from above, and carries a reignition risk of up to 72 hours after apparent suppression. None of these characteristics feature in the fire risk framework of a typical office building.
In Scotland, the legal duty to address those risks falls on the Duty Holder the employer, building owner, or anyone with control of the premises under the Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006. The Scottish Fire and Rescue Service is the enforcing authority. And in March 2026, the Scottish Government updated the Building Standards Technical Handbooks, including a comprehensive revision of Section 2 (Fire), effective from April 2026 confirming that fire safety requirements for Scottish commercial buildings continue to evolve.
Fire and Safety UK is headquartered in Fife and provides specialist commercial EV charging fire safety services to office buildings and commercial premises across Scotland. This guide covers what Scottish office building decision-makers need to know the risks, the legal obligations, the specific hazards of workplace EV charging environments, and how to commission the assessment and protection programme their premises actually requires.
Why Commercial EV Charging Creates a Different Fire Risk Category for Scottish Offices
Lithium-Ion Battery Thermal Runaway in an Office Car Park Environment
The dominant hazard introduced by commercial EV charging in Scottish office buildings is not the charging equipment itself it is the lithium-ion battery in the vehicle being charged. When a lithium-ion battery cell experiences overheating, physical damage, overcharging, or a manufacturing defect, it can enter thermal runaway a self-sustaining electrochemical chain reaction that generates its own heat and oxygen.
A battery cell entering thermal runaway can reach temperatures of 800°C to 1,000°C within seconds, with cell-to-cell propagation occurring in as little as three to ten seconds per module. The fire releases toxic gases including hydrogen fluoride, carbon monoxide, and methane. It cannot be interrupted by dry powder or CO2 suppression. It can reignite days after apparent extinguishment. And critically the battery pack is mounted beneath the vehicle floor, below the reach of overhead sprinkler systems that deliver water from above.
For Scottish office buildings, the most common charging environment an enclosed or underground car park beneath or adjacent to the office structure is the highest-risk configuration for an EV battery fire event. Enclosed spaces trap heat, smoke, and toxic gases. Ventilation systems may not be designed for lithium battery off-gas volumes. Evacuation routes serve both the car park and the office building above. A single thermal runaway event in an enclosed car park has the potential to affect building occupancy, occupant safety, and the structural integrity of the office above.
The 2025 decision by the UK Parliament to halt EV charging in its own covered car parks after assessing the fire risk profile a decision that prompted wide discussion across the commercial property sector is the most visible signal of how seriously this risk is being treated at institutional level. Scottish office building owners and facilities managers cannot reasonably treat the same risk as a routine matter of standard fire safety practice.
Electrical Infrastructure Overloading
Most Scottish office buildings were designed and connected to the electrical grid before EV charging was contemplated as a workplace requirement. The addition of EV charge points particularly fast and rapid chargers operating at 7kW to 22kW per bay places demand on the building’s electrical infrastructure that it was not designed to serve.
Overloaded circuits, undersized cables, and inadequate earthing arrangements created by EV charger installation without prior electrical infrastructure assessment are among the most common causes of commercial premises fires. An EV fire safety programme for a Scottish office building that addresses only the vehicle fire risk without evaluating the electrical infrastructure that powers the chargers is incomplete.
Charge points should only be installed by an authorised company. Allianz guidance on commercial EV charging premises confirms that installation and inspections must be carried out by a qualified person in accordance with BS EN 61851-1:2019 the electric vehicle conductive charging system standard and the IET Code of Practice for Vehicle Charging Equipment Installations. Compliance with these installation standards is the first line of fire prevention for office building EV charging, and it must be verified as part of any credible EV fire risk assessment.
The Enclosed Car Park Challenge
The fire safety challenge presented by EV charging in enclosed car parks is well recognised at regulatory level. Current government guidance stresses that enclosed car parks require careful placement of chargers, attention to ventilation, and consideration of how heat and smoke may accumulate during an incident.
Research published in December 2025 on real EV fires in car park environments raises specific questions about the effectiveness of standard OH3 and HHP3 sprinkler systems in EV battery fire scenarios, and recommends formal research into whether it would be more appropriate to use the hydrocarbon fire growth curve rather than the standard time-temperature fire growth curve when designing for EV battery fires. This ongoing uncertainty in the research base means that building on standard sprinkler design alone without specialist EV suppression provision carries technical risk that Scottish office building owners should not accept.
The guidance from fire engineering specialists is clear: unless validated by appropriate testing, suppression cannot be relied on to mitigate the risk. For Scottish office buildings with enclosed car park EV charging, bay-level specialist suppression is not optional best practice it is the technically defensible baseline.
Legal Obligations for Scottish Office Buildings with EV Charging
The Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006
The Fire (Scotland) Act 2005 is the primary fire safety legislation for all non-domestic premises in Scotland. It places legal duties on Duty Holders defined as employers or any other person who has control to any extent over any part of the premises, such as the occupier or owner. In Scotland, the Duty Holder is the counterpart to the Responsible Person designation under the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
The core duty under the Act is unambiguous. Under Section 53, the Duty Holder is required to carry out a fire risk assessment of the workplace for the purpose of identifying any risks to the safety of employees in respect of harm caused by fire. The Fire Safety (Scotland) Regulations 2006 add the requirement to equip the building with firefighting equipment and fire detectors and fire alarms appropriate to the identified risk.
The Scottish Fire and Rescue Service places responsibility for assessing risk from fire and providing appropriate fire safety measures with those with control of premises the Duty Holder. The Service has powers to visit premises and issue enforcement notices where fire precautions are not maintained to a satisfactory standard. Non-compliance carries the risk of prosecution as well as prohibition orders that can close a commercial premises.
A review of the fire risk assessment is mandatory whenever there has been a significant change to the premises, or to the processes within the premises, that may affect the validity of the previous assessment. The installation of EV charging infrastructure at a Scottish office building is precisely this kind of significant change and it triggers an immediate obligation to update the fire risk assessment to reflect the new risk profile.
The Building (Scotland) Regulations 2004 EV Charging Requirements
From 5 June 2023, the Building (Scotland) Regulations 2004 have required EV charge point provision in new non-domestic buildings and buildings undergoing major renovation. For non-domestic buildings with more than ten car parking spaces, the requirement is for at least one in ten spaces to have access to a charge point socket. This applies to new buildings and to existing buildings undergoing major renovation.
This requirement means that EV charging infrastructure is now a standard specification element in new Scottish office development. Every new office building with associated parking in Scotland built or substantially renovated since June 2023 carries EV charging provision as a regulatory requirement and with it, the associated fire risk obligations.
The Building Standards Technical Handbooks were updated in April 2026, incorporating revisions to Section 2 (Fire) that reflect the Scottish Government’s response to the Grenfell Tower Inquiry and an ongoing Call for Evidence reviewing fire safety requirements across all building types. The direction of travel in Scottish building standards is toward more detailed and more prescriptive fire safety requirements not less. Office building owners who address EV charging fire safety proactively are building a compliance position that will remain sound as standards continue to tighten.
PAS 1899 EV Charging Infrastructure Safety
PAS 1899, published by the British Standards Institution, is the UK’s primary specification for EV charging infrastructure safety. It establishes baseline requirements for fire risk management in EV charging environments and is increasingly referenced by commercial insurers as a minimum standard for commercial property coverage where EV charging is installed. Scottish office building managers specifying or maintaining EV charging infrastructure should treat PAS 1899 compliance as a standard requirement of the installation and maintenance programme.
Insurance Obligations
Scottish commercial insurers are adjusting their approach to EV charging risk across the commercial property sector. Longer repair times, higher replacement costs, and specialist battery handling following a fire event add pressure on claims costs. Insurers are paying close attention to where and how vehicles are charged, and whether businesses have appropriate fire safety measures in place before agreeing policy terms.
A Scottish office building with EV charging infrastructure that has not commissioned an updated fire risk assessment or installed appropriate suppression provision faces coverage risk that a Duty Holder cannot afford to carry as a background assumption. A documented EV fire risk assessment from a specialist consultancy, combined with professional installation of appropriate suppression systems, provides the evidence trail that protects both the building’s compliance position and its insurance standing.
What an EV Charging Fire Risk Assessment Must Cover for Scottish Office Buildings
A fire risk assessment for a Scottish office building with EV charging is not a general office premises assessment with an additional paragraph. It is a site-specific technical document that must address the specific characteristics of the EV charging environment within or adjacent to the building.
The Scottish Fire and Rescue Service fire risk assessment guidance is clear that the assessment should identify ignition sources, fuel, and oxygen and by reducing unattended ignition sources and combustible materials, the chances of a fire starting are reduced. For EV environments, the ignition source is not a naked flame or a piece of electrical equipment in the conventional sense. It is an electrochemical process within a battery cell that may begin without visible precursor and escalate within seconds to a self-sustaining thermal event. An assessor who does not understand this specific ignition pathway cannot produce a suitable and sufficient assessment for a premises with EV charging.
The assessment for a Scottish office building with EV charging must cover:
Car park environment and configuration. Whether the car park is enclosed, underground, or open-sided determines the ventilation conditions, gas accumulation potential, and the consequences of a thermal event for the building structure and occupants above. Enclosed car parks with EV charging represent the highest risk configuration and require the most detailed assessment and the most robust suppression specification.
EV charging bay layout and separation distances. The positioning of EV charging bays relative to each other, to building structural elements, and to occupied areas of the building determines the propagation risk from a single thermal event. Separation guidance must be assessed against the actual bay layout, not a generic standard.
Electrical infrastructure adequacy. The building’s electrical supply, circuit design, and earthing arrangements must be evaluated for adequacy against the EV charging load being placed on them. Chargers must be installed by authorised companies and inspected by qualified persons in accordance with BS EN 61851-1:2019 and the IET Code of Practice and the assessment must verify that this has been done.
Existing detection provision. Conventional smoke and heat detectors in a car park environment are designed for standard vehicle fires and building fires. They are not configured to detect the precursor gas signature that a lithium battery releases before thermal runaway initiates. The assessment must evaluate whether the existing detection provision will give adequate warning in an EV battery fire scenario and specify upgrades where it will not.
Suppression system adequacy. The assessment must evaluate whether existing suppression systems are adequate for EV battery fires. Given that overhead sprinkler research as recently as December 2025 questions whether standard systems are effective against EV battery fires in enclosed environments, the assessment must specifically address what suppression provision is appropriate for the car park configuration and must not assume that existing systems are adequate without technical justification.
Emergency procedures and reignition protocol. The assessment must include emergency procedures that address the specific characteristics of a lithium battery fire, including toxic gas evacuation, liaison with the Scottish Fire and Rescue Service, and a defined post-incident monitoring protocol for the reignition window.
Occupant risk profile. An office building car park is used by both staff and visitors throughout the day. The assessment must consider the occupant profile during all operating periods including early morning and evening when parking areas may be used but the main building is less occupied and ensure that escape routes from the car park serve all relevant persons effectively.
Suppression and Protection Solutions for Scottish Office Buildings
Fire and Safety UK supplies and installs the primary commercial EV fire suppression systems for Scottish office building environments. The correct solution is always determined by a physical site assessment the following overview explains the systems and their appropriate application for office building contexts.
EV FirePro Bay-Level Fixed Suppression
EV FirePro is the primary recommendation for enclosed and underground car parks serving Scottish office buildings. It is a permanently installed, floor-mounted suppression system positioned within each EV charging bay. When a thermal event is detected, EV FirePro activates automatically delivering targeted water spray upward to the vehicle undercarriage, where the battery pack is located, and laterally to protect adjacent vehicles and building structure.
EV FirePro addresses the fundamental limitation of overhead sprinkler systems: it reaches the battery pack from below, where the fire originates, rather than attempting suppression from above where water cannot penetrate the vehicle floor. It operates without human intervention a critical advantage for office buildings where the car park may be unattended during overnight or weekend charging periods.
The system measures 1,990mm x 1,270mm with a profile of less than 30mm above floor level, allowing installation in both new-build car parks specified under the Building (Scotland) Regulations EV requirement and in existing car parks being retrofitted with EV charging provision. It connects to the building’s existing water supply and integrates with the fire detection and alarm infrastructure, allowing automatic activation on confirmed thermal event.
EV FirePro was developed in consultation with fire brigade personnel and independently tested at Applus+ Laboratories in Spain under simulated EV thermal runaway conditions in an enclosed car park environment. The testing evaluated fire spread behaviour, adjacent vehicle exposure, heat conditions, and operational response validating the system’s ability to control fire spread, reduce external heat exposure, and create safer conditions for Scottish Fire and Rescue Service personnel responding to an incident.
For Scottish office building owners and property managers specifying or procuring EV charging fire protection, EV FirePro represents the current standard for enclosed car park EV fire suppression a system with documented independent testing, fire brigade design input, and a technical specification that directly addresses the hazard profile identified by the most recent EV car park fire safety research.
The Turtle Fire System
The Turtle Fire System is a deployable vehicle-level suppression device that delivers high-volume water cooling directly to the battery pack from beneath a burning vehicle. It is the appropriate specification for Scottish office buildings where a staffed response is available within the critical initial minutes of a fire event whether through on-site security, a car park attendant, or a trained staff response team.
The Turtle system requires no fixed installation, connects to a standard fire hose supply, and is deployed by pushing it beneath the burning vehicle using a 5-foot handle keeping the operator away from the toxic gas cloud generated by the thermal event. Once positioned, it operates unmanned, delivering sustained cooling to the battery pack while the operator withdraws to a safe distance.
For Scottish office buildings that cannot install EV FirePro immediately due to retrofit complexity, phased implementation programmes, or car park structural constraints the Turtle Fire System provides deployable interim protection that can be operational while a permanent suppression installation programme is planned and procured.
Trident Synthetic Fire Foam Concentrate
Trident is a PFAS-free synthetic foam concentrate designed for lithium battery fire environments. For Scottish office buildings whose fire emergency plans include foam application as part of the post-incident response including reignition management during the extended 24 to 72 hour window Trident provides the compliant, high-performance replacement for AFFF that environmental regulators and Scottish Environmental Protection Agency (SEPA) guidelines increasingly require.
Fire Extinguisher Provision and Servicing
Alongside specialist EV suppression, all Scottish office buildings with EV charging must maintain appropriate fire extinguisher provision and regular servicing to the standards required under the Fire Safety (Scotland) Regulations 2006. Fire and Safety UK’s fire extinguisher servicing programme covers the full range of extinguisher types applicable to office building environments, ensuring that standard fire safety equipment remains compliant and tested alongside any specialist EV suppression systems installed.
EV Charging Fire Safety Across Scottish Office Building Types
The fire risk profile and appropriate suppression specification varies by the type of office building and its associated parking arrangement. The following table summarises the primary scenarios and the relevant protection approach for each.
| Office Building Type | Parking Configuration | Primary Risk | Recommended Protection |
| City centre multi-storey office | Underground or multi-deck enclosed car park | Thermal event in enclosed space; gas accumulation; evacuation complexity | EV FirePro bay-level fixed suppression as primary system |
| Business park office with surface parking | Open-air or partially covered car park | Thermal event propagation; proximity to building entrance | EV FirePro for covered bays; Turtle system for open areas |
| Mixed-use commercial development | Shared basement car park across retail and office | Occupant mix complexity; service access constraints | EV FirePro with integrated detection; updated emergency procedures |
| Office campus with multiple buildings | Distributed surface and covered parking | Multiple charging locations; varied risk profiles | Site-wide assessment; zoned protection programme |
| Listed or heritage office building | Surface or courtyard parking | Structural proximity; evacuation route sensitivity | Turtle system; detailed emergency procedures |
| New-build office (post-June 2023) | Car park with mandatory EV charging provision | EV charging specified in design fire safety must match | EV FirePro specified at design stage; integrated with building fire system |
For new Scottish office developments incorporating EV charging under the Building (Scotland) Regulations requirement, specifying EV FirePro at the design stage is significantly more cost-effective than retrofitting after construction is complete. The integration of bay-level suppression into the building’s fire detection infrastructure is straightforward when designed in from the outset and complex when imposed on a completed structure.
The Scottish Office Building EV Charging Fire Safety Compliance Checklist
The following checklist provides Scottish office building Duty Holders with a structured framework for assessing their current EV charging fire safety compliance position.
Has the fire risk assessment been updated since EV charging was installed? The Fire (Scotland) Act 2005 requires a review whenever significant changes are made to the premises. EV charging installation is a qualifying material change. If the assessment has not been updated since the chargers were installed, the Duty Holder is in breach of their statutory obligation.
Was the EV charging infrastructure installed by an authorised company? Charge points must be installed by an authorised company and inspected by a qualified person in accordance with BS EN 61851-1:2019 and the IET Code of Practice. The installation record should be available as part of the building’s fire safety documentation.
Has the building’s electrical infrastructure been assessed for EV charging load capacity? An electrical infrastructure assessment should confirm that the supply, circuits, and earthing arrangements are adequate for the EV charging load. Overloaded circuits are among the primary causes of commercial premises fires and are a common finding in office buildings that have added EV charging without prior infrastructure review.
Does the existing detection system include off-gas precursor detection for the car park? Standard smoke and heat detectors do not detect the precursor gas signature of a lithium battery approaching thermal runaway. Where the car park is enclosed, gas sensor provision should be assessed and upgraded where standard detection only is present.
Does the car park have bay-level suppression appropriate for EV battery fires? Standard overhead sprinklers are not confirmed to be adequate for enclosed EV car park fire scenarios. For enclosed parking, EV FirePro bay-level suppression should be assessed and, where not present, specified and installed.
Do emergency procedures address lithium battery fire characteristics? Emergency procedures must address toxic gas evacuation, liaison with the Scottish Fire and Rescue Service including vehicle type identification, and a post-incident reignition monitoring protocol for the 24 to 72 hour window following apparent suppression.
Has the Duty Holder engaged with the Scottish Fire and Rescue Service? Proactive engagement with the local Scottish Fire and Rescue Service regarding EV charging provision and fire safety measures is strongly advisable for all Scottish office buildings, particularly those with enclosed car parks and overnight charging. The Service will visit premises to assess whether fire precautions are being maintained to a satisfactory standard it is significantly better to have addressed any gaps before that visit than after.

Frequently Asked Questions
What fire safety legislation applies to office buildings with EV charging in Scotland?
The Fire (Scotland) Act 2005 and the Fire Safety (Scotland) Regulations 2006 place legal duties on Duty Holders to carry out and maintain suitable and sufficient fire risk assessments. The Building (Scotland) Regulations 2004, updated with a revised Section 2 (Fire) from April 2026, also apply and from June 2023 have required EV charge point provision in new non-domestic buildings with more than ten parking spaces.
Do Scottish office buildings need a separate fire risk assessment for EV charging?
Yes. The Fire (Scotland) Act 2005 requires the fire risk assessment to be reviewed whenever significant changes are made to the premises. EV charging installation is a qualifying material change a Duty Holder who installs EV charging without updating the fire risk assessment is in breach of their legal obligation.
What are the main fire risks of EV charging at Scottish office buildings?
Thermal runaway in lithium-ion vehicle batteries during charging, electrical infrastructure overloading, toxic gas accumulation in enclosed car parks, fire propagation to adjacent vehicles, and reignition risk for up to 72 hours following apparent suppression. These risks are not addressed by conventional office building fire safety systems.
What does the Building (Scotland) Regulations EV charging requirement mean for fire safety?
From June 2023, at least one in ten parking spaces in new non-domestic buildings and major renovations with more than ten spaces must have access to an EV charge point socket. This makes EV charging a standard feature of new Scottish office development and creates associated fire risk obligations that must be addressed through an updated fire risk assessment and appropriate suppression provision.
Who enforces EV charging fire safety compliance for office buildings in Scotland?
The Scottish Fire and Rescue Service enforces fire safety legislation for commercial premises in Scotland, with powers to visit premises, issue enforcement notices, and prosecute non-compliance. For building standards, local authorities act as the verifier and enforcing body.
What suppression systems are recommended for EV charging in Scottish office car parks?
For enclosed and underground car parks, EV FirePro bay-level fixed suppression is the primary recommendation it activates automatically, delivers water directly to the battery pack from below, and is independently tested for EV enclosed car park environments. The Turtle Fire System is appropriate where a staffed deployable response is available.
Does Fire and Safety UK provide EV charging fire risk assessments for office buildings across Scotland?
Yes. Fire and Safety UK is based in Fife and provides specialist EV charging fire risk assessments and suppression system installation for commercial office buildings across Scotland, including Edinburgh, Glasgow, Aberdeen, Dundee, Inverness, and surrounding areas.
Scottish Office Buildings Must Act on EV Charging Fire Risk Now Not When Enforcement Arrives
The Scottish regulatory environment for EV charging fire safety is not standing still. Section 2 (Fire) of the Building Standards Technical Handbooks was updated in April 2026. A Call for Evidence reviewing fire safety requirements across all Scottish building types is underway. The Scottish Fire and Rescue Service visits commercial premises and issues enforcement notices where fire precautions are not maintained to a satisfactory standard.
For Scottish office building Duty Holders, the window for proactive compliance action is open. Every month that passes without updating the fire risk assessment, without verifying electrical infrastructure adequacy, and without installing appropriate enclosed car park suppression is a month of compounding legal and insurance exposure.
The fire risk is real. The legal obligation is clear. The suppression technology to address it is available, tested, and deployable. The only decision left is whether to act before an incident or after one.
Fire and Safety UK is ready to support Scottish office building owners, property managers, and facilities directors through every stage of EV charging fire safety compliance from the initial risk assessment to system installation, servicing, and ongoing regulatory monitoring.
