What Buildings Need Fire Risk Assessments in the UK?

A lender, insurer or enforcement officer may ask for a fire risk assessment at short notice, but the need should not come as a surprise. Understanding what buildings need fire risk assessments helps property stakeholders protect occupants, meet their legal duties and avoid costly delays to lettings, refinancing or conveyancing.

In England and Wales, the principal legislation is the Regulatory Reform (Fire Safety) Order 2005. It applies to almost all non-domestic premises and to the shared areas of multi-occupied residential buildings. The duty is not limited to large offices or high-rise blocks. A small shop, a village hall, an HMO and a charity-run community centre can all fall within scope.

What buildings need fire risk assessments?

A suitable and sufficient fire risk assessment is required where the Fire Safety Order applies. In practical terms, this includes premises where people work, visit, receive care, stay overnight or share escape routes. The assessment must identify fire hazards, people at risk, existing precautions and any further action needed to reduce risk.

The legal duty sits with the “responsible person”. This is usually the employer, owner, landlord, managing agent or another person with control over the premises. There can be more than one responsible person in a building, particularly where a landlord controls common parts while tenants control their own commercial units.

The following building types commonly require a documented assessment.

Workplaces and commercial premises

Offices, shops, salons, warehouses, factories, workshops, restaurants, pubs, hotels and serviced offices all require fire risk assessment where staff, customers, contractors or visitors use the premises. The scale of the assessment should reflect the risks present.

For example, an office with a single protected staircase presents different considerations from a commercial kitchen with cooking oils, extraction systems and late-night occupancy. A warehouse may need particular attention to stored materials, charging areas, mezzanines, vehicle movements and the distance to a safe exit. The principle is the same: fire precautions must be appropriate for the people and activities in the building.

Residential blocks, HMOs and shared accommodation

The common parts of blocks of flats are covered by the Fire Safety Order. This includes entrance halls, staircases, corridors, bin stores, plant rooms, shared escape routes and areas containing fire-safety equipment. The individual flats themselves are generally private domestic premises and are not assessed in the same way, although flat entrance doors, external walls and certain associated elements can be relevant to the overall fire-safety assessment of a multi-occupied building.

Houses in multiple occupation require especially careful consideration. Occupants may be unfamiliar with each other, have different routines, or rely on shared kitchens and hallways to escape. Fire doors, detection and warning systems, emergency lighting, escape-route management and the evacuation strategy should all be assessed against the actual layout and occupancy.

A converted house containing bedsits, a block of purpose-built flats and a supported-living property may each have different requirements. Assuming that a residential building is exempt because people live there is one of the most common and consequential mistakes landlords make.

Public, educational and care premises

Schools, nurseries, colleges, universities, libraries, museums, leisure centres, council buildings, places of worship and community halls usually need a fire risk assessment. These buildings can have variable occupancy, public access and people unfamiliar with their surroundings, which makes clear escape arrangements essential.

Healthcare settings, care homes, clinics and supported accommodation need additional care because occupants may need assistance to evacuate. The assessment should consider mobility, cognitive impairment, sleeping risk, staffing levels, evacuation aids and the suitability of the chosen evacuation strategy. A generic report is rarely enough in these settings.

Charities and non-profit organisations are not exempt. If an organisation employs people, hosts members of the public, hires out rooms or manages a building with shared access, it should establish whether the Fire Safety Order applies and ensure its assessment is current.

Mixed-use, vacant and temporary-use buildings

Mixed-use properties require coordination. A shop with flats above, an office within a converted building or a restaurant beneath residential accommodation may have separate responsible persons but interconnected fire risks. Shared corridors, service risers, alarm arrangements and escape routes need clear management responsibilities.

Vacant premises can still need assessment and active fire-safety controls. Empty buildings remain vulnerable to arson, unauthorised entry, damaged fire doors, isolated alarm systems and contractor activity. Before refurbishment, reletting or redevelopment, the responsible person should review the changing risk profile.

Construction and refurbishment sites also require fire-risk management. Temporary electrics, hot works, combustible materials and changing escape routes create risks that need regular monitoring rather than a one-off exercise.

Buildings that are usually outside the requirement

A single private home occupied by one household will not ordinarily require a fire risk assessment under the Fire Safety Order. However, this does not remove wider duties under housing, licensing, building-control or insurance requirements. Landlords should not treat this as permission to ignore fire safety within a rented dwelling.

Likewise, a home-based business may bring part of a domestic property into scope where employees, clients or visitors use it for work. The facts matter. A person working alone on a laptop presents a different situation from a home used for childcare, beauty treatments, storage, tutoring or regular client appointments.

The Fire Safety Order applies in England and Wales. Scotland and Northern Ireland operate under different fire-safety legislation, although the practical expectation remains similar: dutyholders must assess risk, maintain appropriate precautions and protect people who use their premises. For portfolios across the UK, it is sensible to obtain advice that reflects the location and type of each building.

Who must arrange the assessment?

The responsible person must make sure a suitable and sufficient assessment is completed, acted upon and kept under review. In a workplace, that is normally the employer. For common areas in residential premises, it may be the freeholder, building owner, management company, resident management company or appointed managing agent.

Delegating the inspection to a competent assessor does not transfer the legal responsibility. The responsible person remains accountable for understanding the report, implementing proportionate recommendations and maintaining fire precautions afterwards.

Where control is shared, cooperation is essential. A landlord cannot safely manage a common escape route if a commercial tenant stores stock in it. Equally, a tenant needs to know whether a landlord controls the fire alarm, emergency lighting or smoke-ventilation systems. Clear records of responsibility prevent important tasks being missed.

When should a fire risk assessment be reviewed?

There is no universal renewal date that makes every assessment valid or invalid. The assessment must be reviewed regularly and whenever it may no longer reflect the building, its occupants or the risks present. Many organisations choose an annual review as a sensible management standard, but a meaningful review may be needed sooner.

Common triggers include alterations to the layout, a change of use, new equipment, a rise in occupancy, vulnerable residents, a fire incident, enforcement action or significant defects found in testing and maintenance. A new tenant fitting out a unit, for instance, can change the risk to every occupant using the same building.

A report should also be revisited when recommendations have been completed. Closing actions without checking that the measures work in practice can leave a gap between paperwork and reality.

What a useful assessment should provide

A fire risk assessment is not simply a certificate or a tick-box visit. It should give the responsible person a clear, evidence-based record of the premises, its hazards, people at risk, escape arrangements, fire-protection measures and recommended actions.

A thorough report prepared using recognised PAS 79 methodology can be particularly valuable where insurers, lenders, legal conveyancers or enforcement authorities require evidence of compliance. It should distinguish urgent life-safety concerns from longer-term improvements, state who should take action and provide enough detail for contractors or managing agents to respond properly.

Digital access to the report and action plan also matters. Fire-safety records need to be available to those managing the building, not buried in an inbox when an audit, insurance renewal or property transaction arises.

Do not wait for a problem to identify the duty

The question is not whether a building looks high risk from the street. It is whether people use it beyond a single private household, whether there are shared or managed areas, and whether a responsible person has fire-safety duties under the relevant legislation.

If your property falls into an uncertain category, a competent assessment provides clarity before an insurer, tenant, lender or enforcing authority asks for it. Firelux can arrange detailed, insurance-compliant fire risk assessments around occupied premises, with practical reporting that helps responsible persons move from uncertainty to a manageable action plan.
