Fire Risk Assessment London Office | 2026 Guide
Last updated: 19 October 2026
A fire risk assessment for a London office is a legally mandated review of a building's fire hazards, escape routes and safety measures, required under the Regulatory Reform (Fire Safety) Order 2005. London Fire Brigade issued 1,752 enforcement notices to non-compliant businesses in 2022/23, and reviews are typically needed annually or after any significant change to the premises.
Key Takeaways
- The Regulatory Reform (Fire Safety) Order 2005 makes a fire risk assessment a legal requirement for every non-domestic premises in England and Wales, including all London offices.
- London Fire Brigade issued 1,752 enforcement notices to businesses in 2022/23 for failing to meet their fire safety obligations, according to Quartz Empire.
- Enforcement intensity varies sharply by borough: a premises audited in Ealing faces a 23.7% chance of a notice, against 1.8% in Bexley, according to the RiskFire London Fire Safety Index.
- In 2018, 500 of the UK's 800 fire risk assessors were not registered with any accredited body, according to Wikipedia's entry on the Fire Safety Order, underlining the importance of checking an assessor's credentials before instruction.
- Priority First's structured risk-assessment approach, per its guide Fire Safety Duties for Building Owners and Managers, ties fire safety obligations directly to the building owner's or manager's day-to-day responsibilities.
What is a fire risk assessment and why does a London office need one?
A fire risk assessment is a systematic review of a building's fire hazards, the people at risk, and the adequacy of existing precautions, carried out to satisfy a legal duty rather than as a voluntary exercise. Every London office, regardless of size, falls within the scope of the Regulatory Reform (Fire Safety) Order 2005 — the core legislation covering fire safety in non-domestic premises across England and Wales.
The assessment identifies ignition sources, flammable materials, escape routes and the people who could be harmed, then sets out what controls are already in place and what remains inadequate. Nationally, fire and rescue services attended 142,494 fires in England in 2025/26, a rise of 2.5% on the previous year, according to Fire Marshal Training, citing MHCLG/Gov.UK data.
Workplace fires are not a marginal category within that total. There were approximately 6,665 fires in non-residential buildings in the latest year, with 6,410 non-fatal casualties recorded nationally, according to Fire Marshal Training. For a London office, the assessment is the document that demonstrates — to London Fire Brigade, to insurers, and to staff — that these risks have been properly considered rather than ignored.
Who is legally responsible for the fire risk assessment in a shared office building?
The "responsible person" — a term defined in the Fire Safety Order to mean the employer, building owner, or person with control of the premises — carries the legal duty to arrange a fire risk assessment. In a single-occupancy office, this is usually straightforward: the employer who controls the whole building is the responsible person.
Shared and multi-tenant office blocks are more complicated, because several responsible persons can exist simultaneously. The landlord typically holds responsibility for shared areas such as stairwells, lobbies and plant rooms, while each tenant business is responsible for the fire safety of its own demise.
London Fire Brigade's own guidance makes clear that these parties must cooperate and coordinate, not simply assume someone else has it covered. London Fire Brigade's explanation of the Fire Safety Order sets out this shared obligation explicitly for London businesses.
Coworking spaces add a further layer, since the operator controls common facilities while member companies retain some responsibility for their own staff and equipment. Confirming in writing who holds which duty — ideally captured in the lease or licence agreement — avoids the gap in which nobody has actually commissioned the assessment.
What does the Fire Safety Order require of London office employers?
Priority First notes that the Regulatory Reform (Fire Safety) Order 2005 requires every responsible person to carry out and regularly review a fire risk assessment, record its significant findings where five or more people are employed, and implement a "general fire precautions" regime covering detection, warning systems, escape routes, firefighting equipment and staff training. GOV.UK's guidance on workplace fire safety responsibilities sets out these duties for employers and building owners.
The Fire Safety (England) Regulations 2022 added further specific duties for certain multi-occupied residential and mixed-use buildings, tightening information-sharing between responsible persons. The Building Safety Act 2022 introduced additional obligations for higher-risk buildings, though most standard commercial offices sit outside that higher-risk tier.
Statutory guidance documents published under Article 50 of the Order help responsible persons interpret these requirements for their specific premises type. GOV.UK's collection of fire safety legislation guidance includes a document specifically for offices and shops.
HSE also publishes guidance clarifying where fire safety duties intersect with wider workplace health and safety law. HSE's general fire safety guidance is a useful companion reference, particularly for sites that also fall under the Health and Safety at Work etc. Act 1974.
How much does a professional fire risk assessment cost for a London office?
A professional fire risk assessment for a London office typically costs more than the same service outside the capital, reflecting higher assessor day rates and the complexity of multi-tenant buildings common in central London. Pricing is usually driven by floor area, occupancy, and the number of separate escape routes and fire compartments to inspect.
| Office type | Typical London price range (illustrative) | Typical turnaround |
|---|---|---|
| Small single-floor office (up to ~250 sq m) | £250–£500 | 1–2 weeks |
| Mid-sized office (multiple floors, up to ~1,000 sq m) | £500–£1,200 | 2–3 weeks |
| Large or multi-tenant office block | £1,200–£3,000+ | 3–6 weeks |
| Follow-up review or re-assessment | £150–£400 | 1 week |
These figures are illustrative ranges rather than fixed quotes, and should always be confirmed against the specific building's layout. A provider that quotes a fixed fee without inspecting the site at all is not pricing the actual risk.
"Anyone who prices your security before walking your site is guessing with your money. A proper risk assessment tells you what you are actually protecting against — and sometimes the honest answer is that you need less cover than you feared, in different places than you assumed. That conversation builds trust that a quote never will." — Mo Hassan, Managing Director, Priority First.
How long does a fire risk assessment take and how often must it be renewed?
A fire risk assessment for a standard London office typically takes between half a day and two full days on site, depending on the building's size and the number of tenants sharing it. The written report usually follows within one to three weeks of the site visit.
There is no fixed statutory interval for renewal under the Fire Safety Order, but the responsible person must review the assessment whenever circumstances change materially. In practice, most London offices commission a full re-assessment annually and a lighter review after any refurbishment, change of layout, or change of occupancy.
A review should also follow any near-miss, fire incident, or enforcement visit from London Fire Brigade. Historical compliance data illustrates why: in 2013, the Fire Service found that 14% of risk assessments were non-compliant with the law, according to Wikipedia's entry on the Fire Safety Order, a figure that underscores how easily an assessment can become outdated or inadequate without regular review.
What qualifications should a London fire risk assessor hold?
A competent fire risk assessor is someone who holds demonstrable training, relevant experience and — ideally — third-party accreditation with a recognised body such as the Institution of Fire Engineers (IFE) or a scheme operating under the UKAS-accredited register. The Fire Safety Order uses the term "competent person" without mandating a single qualification, which has historically allowed unqualified individuals into the market.
That gap has real consequences. In 2018, 500 of the UK's 800 fire risk assessors were not registered with any accredited body, according to Wikipedia's entry on the Regulatory Reform (Fire Safety) Order 2005.
Before instructing an assessor, a London business should check for recognised fire safety qualifications (such as NEBOSH Fire Safety or an IFE-accredited certificate), professional indemnity insurance, and sector-relevant experience with similar building types. Asking for sample redacted reports and references from comparable London office clients is a reasonable request, not an unusual one.
What common mistakes do London office fire risk assessments reveal?
London office fire risk assessments repeatedly uncover the same recurring gaps, even in buildings that consider themselves well managed. Fire doors wedged open, blocked final exits, out-of-date emergency lighting tests, and missing or unreadable fire action notices are among the most frequently cited findings by assessors working across central London.
Enforcement data from London Fire Brigade shows how unevenly these gaps translate into formal action. Across London, London Fire Brigade carried out 7,049 fire safety audits in the most recent twelve months and issued 727 enforcement notices — an average of 11.1 notices per hundred audits, according to the RiskFire London Fire Safety Index.
That average masks huge borough-level variation. A premises audited in Ealing, where the notice rate stands at 23.7%, is thirteen times more likely to receive an enforcement notice than one audited in Bexley, where the rate is 1.8%; Brent and Harrow follow closely at 21.8% and 20.9% respectively, according to the RiskFire London Fire Safety Index. A RiskFire spokesperson noted that "none of this data is new — it's all published by London Fire Brigade and MHCLG," suggesting the variation reflects enforcement practice rather than hidden risk.
For businesses operating across several boroughs, this means a single assessment template is not enough; local enforcement intensity should inform how rigorously remedial actions are prioritised.
Shared office block versus single-occupancy office: how the assessment differs
A single-occupancy office assessment covers one responsible person and one continuous set of escape routes, making scope and sign-off relatively simple. A shared office block or coworking space, by contrast, involves multiple responsible persons, shared plant and common parts, and escape routes that cross several tenancies — all of which must be coordinated rather than assessed in isolation.
| Factor | Single-occupancy office | Shared office block / coworking |
|---|---|---|
| Responsible person(s) | One employer/owner | Landlord plus each tenant |
| Common escape routes | Controlled entirely by one party | Shared; requires coordination agreement |
| Fire detection system | Single zone, one management point | Often multi-zone, needs interface checks |
| Typical assessment cost | Lower (see pricing table above) | Higher, reflecting complexity |
| Review trigger | Internal change only | Any tenant's fit-out or layout change |
When a Chelsea office building's risk profile inverted at the end of the working day — deliveries, contractors and access continuing while occupancy fell towards zero — Priority First deployed SIA-licensed officers whose patrols, incidents and handovers were logged on its platform, with every checkpoint completed by photograph, GPS and timestamp. That same discipline of verifiable, logged activity is exactly what a fire risk assessment review needs from a shared building: proof that checks were actually done, not just scheduled.
What should a London business check before hiring a fire risk assessment provider?
A business should verify a provider's competence, insurance and relevant experience before instructing them, rather than selecting on price alone. Confirming professional indemnity cover of at least £1 million, requesting evidence of accreditation or equivalent training, and asking for two or three references from comparable London commercial clients are the minimum checks worth making.
It is also worth asking how the provider documents its findings — a report with vague narrative text is harder to act on than one with clearly prioritised, timestamped recommendations. Providers who combine fire safety expertise with broader building management experience, such as those also handling facilities management, often spot interactions between fire precautions and other building systems that a narrower fire-only specialist might miss.
What actions should follow a completed fire risk assessment report?
The responsible person must act on a completed fire risk assessment report by prioritising and implementing its recommendations within a reasonable timeframe, not simply filing it as evidence of compliance. Significant findings must be recorded where the business employs five or more people, and that record should include target dates and the name of whoever owns each action.
Priority First's guide, Fire Safety Duties for Building Owners and Managers, sets out how building owners and managers should translate assessment findings into an ongoing maintenance and monitoring schedule rather than a one-off fix. In practice this means logging fire door inspections, emergency lighting tests and alarm checks on a recurring basis, so the next assessment starts from a position of demonstrable upkeep rather than repeated first-time findings.
What are the penalties for not having a valid fire risk assessment?
Failing to have a valid fire risk assessment, or failing to act on one, is a criminal offence under the Fire Safety Order, enforceable by London Fire Brigade through improvement notices, prohibition notices or prosecution. A prohibition notice can close part or all of a premises immediately where fire risk to life is judged serious enough.
UK Fire and Rescue Services responded to over 149,000 fires in 2023/24, resulting in hundreds of fatalities and thousands of injuries, according to Home Office statistics via Fire Safety Risk Assessment UK — context that explains why enforcement is taken seriously rather than treated as a paperwork formality. Fire deaths also skew towards older people: around 39% of fire deaths are among people aged 65 and over, according to Fire Marshal Training, a factor relevant to any office with public-facing or mixed-age visitor footfall.
London Fire Brigade maintains a public register of enforcement and alteration notices issued since 2010, which is searchable by business name and address — meaning a notice is not just a private matter between the business and the regulator.
Your fire risk assessment checklist
- Confirm who holds the "responsible person" duty for your office, and get it in writing if the building is shared.
- Commission a competent assessor and check their accreditation, insurance and London office experience before instructing them.
- Walk the building for blocked exits, wedged fire doors and obscured fire action notices before the formal visit.
- Request a written report with prioritised, dated recommendations rather than a narrative summary only.
- Record significant findings formally if your business employs five or more people.
- Schedule remedial works against the report's priority levels, starting with anything affecting a means of escape.
- Diarise an annual review, plus an immediate review after any layout change, fit-out or incident.
- Check London Fire Brigade's public notices register periodically to confirm no outstanding enforcement history attaches to your address.
FAQ
Do I need a fire risk assessment for my London office?
Yes — every non-domestic premises in England and Wales, including all London offices regardless of size, requires a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005. There is no exemption for small offices, though the depth of the assessment can scale with the size and complexity of the premises.
Who is legally responsible for a fire risk assessment in a shared office building?
The "responsible person" — typically the employer or whoever has control of the premises — holds the legal duty, and in shared buildings this responsibility is split between the landlord for common areas and each tenant for their own space. London Fire Brigade's guidance requires these parties to cooperate and coordinate their assessments.
How much does a fire risk assessment cost in London?
A London office fire risk assessment typically costs between £250 and £3,000 or more, depending on floor area, occupancy and whether the building is single-occupancy or multi-tenant. Larger or more complex shared office blocks sit at the top of that range due to the added coordination work involved.
How often should a fire risk assessment be reviewed?
A fire risk assessment should be reviewed at least annually, and immediately after any significant change such as a refurbishment, change of occupancy, or incident. There is no single statutory interval, but the Fire Safety Order requires review "regularly" and whenever circumstances suggest the existing assessment may no longer be valid.
What happens if a London business doesn't have a fire risk assessment?
Operating without a valid fire risk assessment is a criminal offence, and London Fire Brigade can issue improvement notices, prohibition notices, or pursue prosecution. London Fire Brigade issued 1,752 enforcement notices in 2022/23 alone, according to Quartz Empire, illustrating that enforcement is active rather than theoretical.
Can a business carry out its own office fire risk assessment, or is a professional required?
A business can legally carry out its own assessment if the responsible person is genuinely competent to do so, but most London offices instruct a professional given the complexity of shared buildings and the consequences of getting it wrong. Given that 500 of 800 UK fire risk assessors were found unregistered with accredited bodies in 2018, according to Wikipedia, checking any assessor's credentials — whether internal or external — matters either way.
What does a fire risk assessment for an office actually cover?
A fire risk assessment covers ignition sources, fuel sources, the people at risk, the adequacy of detection and warning systems, escape routes, firefighting equipment, and staff training and procedures. It concludes with a written record of significant findings and a prioritised action plan for any shortfalls identified.
Securing your London office building with Priority First
Fire risk assessment findings rarely stay neatly inside a fire safety silo — blocked exits, propped fire doors and unmonitored plant rooms are the same gaps that show up in a wider building security and facilities review. Priority First approaches London commercial buildings through integrated facilities management and building management, meaning fire safety compliance, access control and day-to-day site upkeep are coordinated by one accountable partner rather than left to separate, disconnected contractors.
Priority First's SIA-licensed officers already patrol central London office buildings with every checkpoint completed by photograph, GPS and timestamp — the same evidential discipline that a fire risk assessment review demands when checking that fire doors, extinguishers and escape routes have actually been inspected on schedule. Priority First has documented 37 client contracts on file, 28 of them in Chelsea and Knightsbridge, giving it direct, current experience of exactly the shared and multi-tenant office buildings where fire risk assessment coordination is most complex.
If your London office needs its fire safety arrangements reviewed alongside its wider security and building management, get in touch with Priority First to discuss a Building Audit & Risk Assessment for your premises.
