Fire Risk Assessment Cost for London Offices 2026

Last updated: 13 November 2026

A fire risk assessment for a typical London office costs between £250 and £900, depending on floor area, number of storeys and whether the building is single-occupied or multi-tenanted. Small offices under 150m² sit nearer £200–£450, while multi-floor or multi-occupied blocks in central London push towards £900 or more, according to MetroFire.

Key Takeaways

• A small London office typically pays a modest sum, plus VAT, for a professional fire risk assessment, per Quartz Empire.
• Multi-occupied office buildings of one to five floors in London cost £450–£900, while a Type 4 destructive survey on a 20-storey block can exceed £6,000, according to MetroFire.
• London-based assessments carry a 15–20% premium over national rates because of travel and logistics within the capital, says Quartz Empire.
• The Regulatory Reform (Fire Safety) Order 2005 makes a fire risk assessment a legal duty, not an optional service, for the "responsible person" at any non-domestic premises, per legislation.gov.uk.
• Priority First has secured over £1.6 billion in client assets across prime central London buildings where fire and security risk are assessed and managed together.

What Is a Fire Risk Assessment, and What Does It Cost for a London Office?

A fire risk assessment is a systematic review of a building's fire hazards, escape routes, detection systems and management arrangements, carried out to identify risks to life and property and the control measures needed to reduce them. For a standard London office, the cost typically falls between £250 and £900, though the exact figure depends heavily on floor area, occupancy type and building height.

Independent pricing data shows a wide spread across the market. Quartz Empire puts a small London office at £250–£450 plus VAT, while RiskFire quotes £150–£330 for a standard office under 18 metres in height nationally.

LPA+ breaks the market down by floor area: small offices or shops under 1,000 sq ft cost £295–£450, medium commercial properties between 1,000 and 5,000 sq ft cost £450–£850, and large commercial or industrial premises over 5,000 sq ft cost £850–£2,000 or more. For multi-occupied office blocks of one to five floors specifically, MetroFire prices the work at £450–£900, rising to over £6,000 for a Type 4 destructive survey on a 20-storey building. A straightforward, lower-risk single-tenant office in a borough like Westminster or Kensington and Chelsea will sit at the lower end of that range; a shared, multi-tenanted building in the City of London with complex escape routes will sit higher.

What Factors Affect the Price of a Fire Risk Assessment for Office Size and Floors?

Office size, number of floors, occupancy density and building complexity are the main variables that move a fire risk assessment quote up or down. Pro Calculator UK sets out a clear banding: a small office or retail unit under 150m² typically costs £200–£400 and takes two to three hours on site, while a medium office of 150–500m² costs £400–£700.

Beyond floor area, assessors price for:

• Number of storeys — each additional floor adds inspection time and escape-route complexity.
• Single versus multi-occupancy — shared buildings with several tenants need a more detailed review of communal fire doors, stairwells and management coordination.
• Building height — anything approaching or exceeding 18 metres moves into higher-risk categories under the Fire Safety (England) Regulations 2022, often requiring a more thorough Type 2 or Type 3 survey.
• Age and layout of the building — period conversions common across Mayfair, Chelsea and Knightsbridge frequently have irregular escape routes that take longer to assess than purpose-built offices.
• Previous fire safety history — a building with existing enforcement notices or past incidents typically needs a more detailed assessment.

Location within London itself is also a direct cost factor. Anyrisks notes that London and South East rates run 20–30% higher than the national average, while Quartz Empire specifically attributes a 15–20% London premium to increased logistics and travel time for assessors working within the capital.

Is a Fire Risk Assessment a Legal Requirement for London Office Buildings?

Yes, a fire risk assessment is a legal requirement for every non-domestic premises in England and Wales, including offices, under the Regulatory Reform (Fire Safety) Order 2005. This duty sits with the "responsible person" — typically the employer, building owner or managing agent — who must identify fire hazards and reduce risk to employees, visitors and anyone else on the premises.

The Health and Safety Executive confirms that employers, building owners or occupiers must carry out a fire safety risk assessment and keep it current. The official GOV.UK guide for offices and shops sets out exactly how this should be approached for premises like a standard London office.

Since the Fire Safety (England) Regulations 2022, responsible persons have also faced tightened recording duties. West Sussex Fire and Rescue Service confirms that assessments must be recorded in full since October 2023 regardless of staff numbers — a change that removed the previous exemption for smaller employers. There is no published gov.uk fee scale for this work; every price figure in this article comes from commercial assessor pricing, not a government benchmark.

Who Is Legally Responsible for Arranging a Fire Risk Assessment: Landlord or Tenant?

The "responsible person" defined under the Regulatory Reform (Fire Safety) Order 2005 holds the legal duty to arrange a fire risk assessment, and that person can be the landlord, the managing agent, or the tenant depending on the lease arrangement. Home Office guidance explains that in multi-occupied buildings, the responsible person is usually whoever has control of the common parts — often the landlord or managing agent — while each tenant remains responsible for fire safety within their own demise.

In practice, this means a single-tenant office building usually places the duty squarely on the occupying business, while a multi-let office block needs the landlord or managing agent to commission a whole-building assessment covering shared stairwells, lobbies and plant rooms, alongside each tenant's own internal review. Guidance Note No. 1 on enforcement confirms that more than one person can hold responsible-person duties simultaneously, with each accountable for the parts of the premises under their control.

This is precisely the kind of split responsibility that creates gaps. Priority First's guide, Fire Safety Duties for Building Owners and Managers, sets out how owners and managers across prime central London buildings can map who holds which duty before a gap becomes a liability.

How Does an Independent Fire Risk Assessor Compare to a Larger Consultancy on Cost?

An independent, self-employed fire risk assessor generally charges less than a larger fire safety consultancy for the same office assessment, though the difference narrows for complex or multi-floor buildings. MyBuilder puts the national range at £200 to £1,500 or more for a thorough assessment, a spread wide enough to cover both ends of the market.

Sources: RiskFire, MetroFire, LPA+

A larger consultancy typically carries professional indemnity insurance at a higher level and can offer follow-up fire safety management, which independents may not. Mo Hassan, Managing Director of Priority First, makes a point that applies just as much to fire risk assessment as to guarding contracts: "When a quote is dramatically cheaper than the rest, the saving has come from somewhere — usually the officer's pay, their training, or the vetting behind them. Tired, underpaid officers on your site are a risk you have paid to acquire. Value in this industry means knowing exactly what your money buys." The same logic applies to an assessor cutting corners on inspection time to hit a lower quote.

Fire Risk Assessment Versus Other Compliance Checks

Office managers juggling several statutory checks often compare fire risk assessment costs against PAT testing and gas safety inspections. A fire risk assessment is a far broader exercise — covering escape routes, fire doors, signage, management procedures and detection systems — rather than a single-item electrical or gas check, which is why it commands a higher price than a routine PAT testing visit per appliance.

What Does a Fire Risk Assessment Report Include and How Long Does the Process Take?

A fire risk assessment report is a written document identifying fire hazards, the people at risk, existing control measures, and a prioritised action plan for any shortfalls found during the site visit. For a small office under 150m², Pro Calculator UK states the on-site visit itself typically takes two to three hours.

A typical report for a London office covers:

1. Fire hazards identification — sources of ignition, fuel and oxygen across the premises.
2. People at risk — staff, visitors, contractors and anyone with mobility impairments.
3. Evaluation of existing measures — fire doors, alarms, extinguishers, emergency lighting and signage.
4. Risk rating — an overall judgement of the premises as low, normal, substantial or intolerable risk.
5. Action plan — a prioritised list of remedial works with target dates.
6. Review date — the point at which the assessment must be revisited.

Reviews should happen at least annually, or sooner following any significant change — a refit, new tenant, structural alteration or a fire safety incident. Priority First's self-assessment resource, the Building Security Audit: Self-Assessment guide, gives building managers a structured way to check their own premises between formal reviews — a useful companion to the fire risk assessment itself, since many of the same checkpoints (access control, escape routes, signage) overlap with wider building security.

Worked Scenarios: What a London Office Should Budget

Three illustrative scenarios show how the figures from this research translate into real budgeting decisions. These are indicative ranges built from the sources cited throughout this article, not fixed quotes.

• Small single-tenant office, Soho, under 150m²: Based on Pro Calculator UK's banding and Quartz Empire's London pricing, budget roughly £250–£450 plus VAT for the full assessment and report.
• Medium multi-occupied office, three floors, Victoria: Drawing on MetroFire's multi-occupied banding, expect £450–£900 for a building with shared stairwells and several tenants.
• Large commercial premises, over 5,000 sq ft, City of London: Following LPA+'s large commercial banding, budget £850–£2,000 or more, rising further if the building exceeds 18 metres and needs a Type 2 or Type 3 survey.

Ways to Reduce the Cost

Office managers can keep fire risk assessment costs reasonable without cutting corners on compliance:

• Bundle the assessment with wider building audits — combining a fire risk assessment with a general security and facilities review, such as Priority First's Building Audit & Risk Assessments service, can reduce duplicated site-visit time.
• Provide floor plans and previous reports in advance — this cuts the assessor's time on site and therefore the invoice.
• Group multiple tenancies into one instruction — a single assessor covering a whole multi-let building is usually cheaper per unit than each tenant commissioning separately.
• Avoid last-minute bookings — assessors often charge a premium for urgent turnarounds ahead of a lease renewal or insurance deadline.

Alternatives to Consider

A fire risk assessment itself cannot be substituted — it is a statutory duty under the Regulatory Reform (Fire Safety) Order 2005. However, businesses can reduce the frequency and scope of costly full re-assessments by maintaining strong ongoing fire safety management between formal reviews, including regular fire door checks, alarm testing records and staff fire warden training, all of which an assessor will note favourably at the next review.

What Are the Penalties for Not Having a Valid Fire Risk Assessment?

Failing to carry out or maintain a suitable fire risk assessment is a criminal offence under the Regulatory Reform (Fire Safety) Order 2005, enforceable by the local fire and rescue authority. Guidance Note No. 1 on enforcement confirms that fire authorities can issue an alteration notice, an enforcement notice, or a prohibition notice restricting or stopping use of the premises entirely where risk is judged serious.

Non-compliance can also invalidate buildings insurance, since most commercial policies require evidence of a current fire risk assessment as a condition of cover. There is no single published fee scale for fines specific to London offices, but the Order allows for prosecution through the courts where breaches are serious or persistent, alongside the immediate operational cost of a forced closure.

Your Fire Risk Assessment Checklist

Use this checklist before commissioning or renewing a fire risk assessment for a London office:

• Confirm who holds "responsible person" duties under the Regulatory Reform (Fire Safety) Order 2005 for your building.
• Establish whether the building is single-occupied or multi-tenanted, since this changes who commissions the assessment.
• Measure floor area and count storeys to anticipate the likely pricing band.
• Request at least two quotes and ask what site-visit time and report format each includes.
• Check the assessor's qualifications and experience with office premises specifically.
• Ask when the last assessment was carried out and whether any actions remain outstanding.
• Set a calendar reminder for the annual review date before the report is even filed.
• Confirm whether VAT is included in any quoted price, since this varies across providers.

FAQ

How much does a fire risk assessment cost for a small office in London?

A small office in London typically costs a modest amount plus VAT for a professional fire risk assessment, according to Quartz Empire. Smaller units under 150m² can fall as low as £200–£400 per Pro Calculator UK.

Who is responsible for paying for a fire risk assessment in a shared office building?

Responsibility depends on the lease: the landlord or managing agent usually commissions the assessment for shared areas, while each tenant covers their own demised space. The Regulatory Reform (Fire Safety) Order 2005 allows more than one responsible person to hold duties over different parts of the same building.

Does the cost of a fire risk assessment include remedial repairs or fire safety equipment?

No, the quoted fee covers the inspection and written report only. Any remedial works identified — new fire doors, signage or extinguishers — are priced and arranged separately, usually by the responsible person acting on the report's recommendations.

How often does a fire risk assessment need to be reviewed or repeated?

A fire risk assessment should be reviewed at least annually, and immediately after any significant change to the building, occupancy or a fire safety incident. The HSE confirms the assessment must be kept up to date as a continuing legal duty, not a one-off exercise.

Can I carry out a fire risk assessment myself to save costs?

Yes, the law permits a competent responsible person to carry out their own assessment for straightforward premises, using resources such as the official GOV.UK offices and shops guide. Complex, multi-occupied or taller buildings are better served by a qualified assessor, since an inadequate self-assessment still leaves the responsible person liable.

What is the difference between Type 1, 2, 3 and 4 fire risk assessments and their costs?

Type 1 is a non-destructive common-area review, Type 2 adds destructive inspection of common parts, Type 3 covers non-destructive inspection of individual flats or units, and Type 4 is a full destructive survey of both common areas and units. MetroFire prices a Type 4 destructive survey on a 20-storey block at over £6,000, far above the £250–£900 range typical of standard office assessments.

What happens if a London office doesn't have a valid fire risk assessment?

Operating without a valid fire risk assessment is a criminal offence under the Regulatory Reform (Fire Safety) Order 2005, and the local fire authority can issue enforcement or prohibition notices restricting use of the premises. It can also void buildings insurance, since most commercial policies require proof of a current assessment.

Securing Your London Office Alongside Fire Safety Compliance

Fire risk assessment is one part of a wider duty of care that every London office building owes its occupants, and it sits closely alongside the physical security and building management work Priority First carries out daily across prime central London. When Priority First took on security for an office building in Chelsea and Knightsbridge, the brief reflected a pattern familiar to any compliance-minded office manager: risk doesn't disappear after 6pm, it changes shape, as deliveries, contractors and access needs continue while occupancy drops towards zero.

SIA-licensed officers were deployed — the Security Industry Authority being the statutory regulator of licensed security personnel under the Private Security Industry Act 2001 — with every patrol, incident and handover logged on Priority First's platform, checkpoints completed with a photograph, GPS location and timestamp. That same evidence-based discipline, applied across 28 of 37 documented client contracts based in Chelsea and Knightsbridge, is what Priority First brings to building audits and fire safety duties through its Building Audit & Risk Assessments service.
