How Much Does a Fire Risk Assessment Cost in the UK? The Factors That Drive Pricing in 2026

It is the question every responsible person, facilities manager, landlord, and business owner asks at some point: how much should a fire risk assessment actually cost? The honest answer is that there is no single figure. A genuinely useful fire risk assessment for a small single-occupancy office and one for a 200-bed care home are completely different pieces of work. So are an assessment for a single building and an assessment across a portfolio of 40 sites.

What does exist is a clear set of factors that drive the cost, and a clear set of warning signs that tell you when a quote is too cheap to be credible. This guide explains both. It is written for anyone responsible for fire safety in a UK premises who needs to understand what they should be paying for and why.

The starting point is the law. A fire risk assessment is not optional. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person for any non-domestic premises must carry out and regularly review a fire risk assessment. The Fire Safety Act 2021 extended that requirement to cover the external walls and individual flat entrance doors of buildings containing two or more domestic premises. The Fire Safety (England) Regulations 2022 tightened the requirements further for high-rise residential buildings. The cost of the assessment, in other words, is the cost of meeting a legal duty, not a discretionary spend.

What a fire risk assessment actually involves

A compliant fire risk assessment is a structured process. It is not a tick-box exercise or a generic template downloaded from the internet. The competent assessor walks the premises, identifies fire hazards and people at risk, evaluates the existing fire safety measures, records the findings, and produces a written report with prioritised actions. That report becomes the legal evidence that the responsible person has met their duties under the Fire Safety Order.

The cost reflects the time and expertise required to do this properly. A small simple office might take half a day on site plus a similar amount of report writing. A complex multi-occupancy building might take several days on site with specialist input from a fire engineer. A national portfolio assessment programme spans weeks or months and requires coordination across sites.

This is why a single headline price for a fire risk assessment is almost always misleading. What you should be asking for is a quote scoped to your specific premises, with the cost factors explained.

The seven factors that drive fire risk assessment cost

1. Type of premises

The single biggest factor. A single-occupancy office, a busy restaurant, a care home, a hotel, a school, a hospital, and a high-rise residential block are not comparable. Each has different hazard profiles, different legal requirements, different occupant types, and different layouts. A care home assessment will always cost more than an equivalent-sized office assessment because the people at risk are less mobile, the operational hours are 24/7, and the regulatory expectations are higher. A school will cost more than an office because of the safeguarding considerations and the assembly-area requirements. Premises type sets the baseline.

2. Size and complexity of the building

Floor area, number of storeys, number of separate compartments, complexity of escape routes, and presence of specialist features (such as theatres, kitchens, laboratories, server rooms, plant rooms, atria, or sub-basements) all add time to the assessment. A 200 square metre single-storey office is straightforward. A 12,000 square metre multi-storey building with three different occupiers, two service basements, and a fire engineered atrium is genuinely complex. The assessment time scales with that complexity, and so does the cost.

3. Type of fire risk assessment required

For non-residential premises, the Fire Safety Order requires one assessment, scoped to the premises. For multi-occupancy residential buildings, the position is more layered. Industry practice recognises four types of fire risk assessment, each with different scope and cost implications:

• Type 1: Common parts only, non-destructive. The most common and least expensive. The assessor inspects communal areas, escape routes, fire doors, signage, and the external envelope without opening up construction.
• Type 2: Common parts only, destructive. Sample opening-up of construction in common parts to verify compartmentation. More expensive than Type 1 because of the works involved and the need for making good afterwards.
• Type 3: Common parts and dwellings, non-destructive. Includes inspection inside a sample of individual flats. Requires resident coordination and significantly more time than Type 1.
• Type 4: Common parts and dwellings, destructive. The most thorough and the most expensive. Sample opening-up inside dwellings as well as common parts.

For most non-residential premises this categorisation does not apply, but for landlords, managing agents, and housing providers, the type required has the biggest single effect on cost. Type 4 assessments can cost several times what a Type 1 assessment costs.

4. Fire safety engineering input

Some premises require input from a chartered fire engineer alongside the fire risk assessor. Examples include buildings with fire engineered solutions (where the fire safety strategy depends on calculated rather than prescriptive design), buildings with complex compartmentation, buildings with smoke control systems, and buildings being assessed against the implications of the Fire Safety Act 2021 or the Building Safety Act 2022. Engineering input adds cost but is sometimes legally and practically essential. Cheap fire risk assessments often miss the need for engineering input entirely, which can be a serious risk to the responsible person.

5. Single premises versus portfolio

Most fire risk assessors price per assessment with no portfolio discount. A few do. Arinite's Chartered consultants work with multi-site portfolios across 1,500+ businesses in 50+ countries, where the assessment programme is scoped as a whole rather than site by site. The unit cost typically falls as the portfolio grows because mobilisation, reporting templates, central coordination, and software-based action tracking can be shared across sites. For businesses with more than five premises, asking for portfolio-based pricing rather than per-site pricing is almost always more cost effective.

6. Frequency of review and ongoing support

A fire risk assessment is not a once-and-done exercise. The Fire Safety Order requires the assessment to be kept under review and revised where it is no longer valid or where there has been a significant change. Most premises need a review at least annually, and a full reassessment every two to three years or after any significant change to the building, the occupants, or the use. Some assessors quote per assessment with no ongoing support. Others offer retained services that include the initial assessment, scheduled reviews, action tracking, and consultant advice as needed. Retained services usually represent better value across a multi-year horizon than commissioning separate one-off assessments each time.

7. Geography and assessor availability

A site in central London is more expensive to assess than an equivalent site in regional England, partly because travel and access costs differ and partly because demand for competent assessors is higher in London. International sites add further cost. Arinite covers UK sites from a London base and international sites through a network of locally-qualified consultants. The cost difference for international assessments is mostly about local consultant rates and travel rather than any fundamental difference in the work.

What you should expect for the money

A fire risk assessment that is genuinely worth what you paid for it will include all of the following:

• A site visit by a competent assessor with documented qualifications and indemnity insurance, not a remote desk-based assessment based on photographs.
• A written report identifying fire hazards, people at risk, existing fire safety measures, and any deficiencies, with each deficiency given a risk rating and a recommended action.
• An action plan with priorities ranked by risk, so the responsible person knows what to address first.
• Compliance with the Fire Safety Order, the Fire Safety Act 2021, and where applicable the Fire Safety (England) Regulations 2022 and the Building Safety Act 2022.
• Photographs and floor plan markings where they aid understanding.
• A clear review schedule and the next review date.
• The assessor available afterwards to discuss findings and clarify actions.

Any quote that does not produce all of the above is not actually saving you money. It is leaving the legal duty unmet and the actions undocumented.

Red flags: when a fire risk assessment quote is too cheap

The fire risk assessment market includes a substantial number of providers who offer assessments at prices well below what the work realistically takes. The volume of "fire risk assessments from £99" advertising should be treated with caution. The common patterns to watch for:

• No physical site visit. Some providers will produce a "fire risk assessment" from a phone call and a few photographs. This is not compliant with the Fire Safety Order and would not be defensible if challenged after an incident.
• Generic templates with the address inserted. A real fire risk assessment is specific to the building. If the report could have been written about any building of that type, it is not a real assessment.
• No competent assessor named. Industry guidance, including the Fire Risk Assessment Competency Council tiered competency framework, expects the assessor to be named and their qualifications stated. Anonymous "assessments" produced by a faceless company are a red flag.
• No engineering input where it is needed. A genuinely cheap fire risk assessment for a complex building has almost certainly skipped the engineering input that the building actually requires. The cost of getting this wrong is far higher than the cost of getting it right.
• No mention of the Fire Safety Act 2021 or the Fire Safety (England) Regulations 2022 where relevant. A residential block assessment that does not address external walls and flat entrance doors is not current with the law.
• No follow-up support. A quote that ends when the report is delivered leaves the responsible person to interpret and act on findings alone. That is rarely a good outcome.

The cost of a single major fire and the prosecution that follows is many orders of magnitude higher than the cost of a properly scoped fire risk assessment. Saving a few hundred pounds on the assessment is not a meaningful saving if the assessment itself does not work.

How Arinite scopes and quotes a fire risk assessment

Arinite's approach is factor-based rather than headline-priced. A typical scoping conversation takes 15 to 20 minutes on the phone and covers:

• The type of premises, its size, and its layout
• Number of occupants and whether any are vulnerable
• Use of the building, including any high-risk activities or specialist features
• Whether the assessment is single-premises or portfolio
• The current position: have there been previous assessments, when, by whom
• Any specific drivers, including landlord requests, insurance requirements, recent changes, or HSE or Fire and Rescue Service involvement
• Whether ongoing review and retained support is wanted

From that conversation, a scoped quote follows. The quote sets out exactly what is included, what is excluded, the timeline, who will do the work, and what the deliverables will be. There are no surprise costs added later.

For multi-site clients, the assessment programme is built around the wider health and safety services Arinite provides, with Chartered consultants acting as the competent person across the full portfolio, results consolidated in compliance software, and action tracking visible to head office across every site.

When you legally need a fire risk assessment

If any of the following apply, your premises requires a fire risk assessment under UK law:

• Any non-domestic premises where people are employed (offices, shops, factories, warehouses, schools, hospitals, care homes, hotels, restaurants, gyms, places of worship, public venues).
• Common parts of any building containing two or more domestic premises (residential blocks, HMOs).
• Any premises to which members of the public have access.
• Workplaces used by self-employed people working with others.

The responsible person is the person who has control of the premises. For a workplace, this is usually the employer. For multi-occupancy buildings, it is usually the landlord or managing agent for the common parts and the occupier for the demised areas. For events, it is the event organiser. Where there are multiple responsible persons in the same building, the Fire Safety Order requires them to cooperate and coordinate.

If you fall into any of these categories and do not have a current fire risk assessment, the position is not that the cost is the priority. The priority is meeting the legal duty.

Scoping your own fire risk assessment requirement

Before you ask for a quote, having clear answers to the following will make every quote you receive more accurate and easier to compare:

• What is the premises? Single building, multiple buildings, single occupier, multiple occupiers.
• What is the floor area and number of storeys?
• How many people use the premises at peak times, and are any vulnerable?
• What is the building used for, and are there any high-risk activities or rooms?
• When was the last fire risk assessment, who did it, and what was its outcome?
• What is your timeline, and are there any external drivers (insurance, landlord, regulatory)?
• Are you looking for a single assessment or an ongoing programme?

Frequently asked questions

How much does a fire risk assessment cost in the UK? Fire risk assessment cost depends on the type of premises, the size and complexity of the building, the level of assessment required (particularly for residential blocks where Type 1 to Type 4 categorisation applies), whether fire engineering input is needed, and whether it is a single assessment or a portfolio. A small simple non-residential premises sits at the lower end. A complex multi-occupancy residential block requiring a Type 4 assessment sits at the higher end. Always ask for a scoped quote rather than relying on a headline figure.

Is a fire risk assessment a legal requirement? Yes. Under the Regulatory Reform (Fire Safety) Order 2005, every UK non-domestic premises must have a current fire risk assessment carried out by a competent person. The Fire Safety Act 2021 extended this requirement to cover external walls and flat entrance doors of buildings containing two or more domestic premises.

How often should a fire risk assessment be reviewed? The Fire Safety Order requires the assessment to be kept under review and revised when no longer valid or following significant change. Most premises adopt an annual review cycle as good practice. A full reassessment is typically required every two to three years or after significant change to the building, occupants, or use.

Who is qualified to carry out a fire risk assessment? The Fire Safety Order requires the assessor to be competent. Competence is typically demonstrated through qualifications (such as those listed by the Institution of Fire Engineers, the Institution of Fire Safety Managers, or the Fire Risk Assessment Competency Council tiered framework), relevant experience, and continuing professional development. Many competent assessors are also registered with third-party certification schemes.

What is the difference between a Type 1 and Type 4 fire risk assessment? Type 1 covers common parts of a residential building only, with no opening up of construction. Type 4 covers common parts and a sample of individual dwellings, with destructive sampling to verify compartmentation. Type 4 is significantly more thorough and significantly more expensive. Type 1 is the most commonly commissioned level. The right level depends on the building, its history, and any concerns raised by previous assessments.

Can I do my own fire risk assessment? The Fire Safety Order does not require an external assessor. The responsible person may carry out the assessment themselves if they are competent to do so. For most non-trivial premises, demonstrating that level of competence is harder than commissioning a qualified assessor, particularly given the consequences of getting it wrong.

What happens if I do not have a fire risk assessment? Failure to comply with the Fire Safety Order is a criminal offence. Enforcement is led by the local Fire and Rescue Service. Penalties range from improvement notices and prohibition notices through to unlimited fines and, in cases involving death or serious harm, imprisonment of the responsible person.

Do small businesses need a fire risk assessment? Yes. There is no minimum size that exempts a UK non-domestic premises from the Fire Safety Order. A sole trader with a single-room workshop is in scope. The scope of the assessment is proportionate to the premises, but the duty is universal.
