01
Occupancy
Numbers, familiarity, sleeping risk and whether the public is present.
Fire Risk Assessor Scope of Competence
What Buildings Can a Fire Risk Assessor Assess?
There is no single qualification that automatically permits an assessor to assess every building in a category. The correct question is whether the assessor has the competence, experience and technical knowledge needed for the particular premises and its risks.
The short answer
Scope follows demonstrated competence
Qualifications contribute to competence, but they are not blanket licences. Appropriate scope depends on qualifications, practical experience, previous building exposure, construction knowledge, occupancy, hazards, fire-protection systems, judgement and continuing professional development.
Building complexity is not a licence band
Qualification level helps demonstrate competence. It does not automatically define every building an assessor can work on.
Assess the actual premises
What changes building complexity?
Two buildings with the same label can create very different assessment demands.
02
Vulnerability
Children, patients, older people and anyone needing evacuation assistance.
03
Height and layout
Storeys, basements, travel distances, corridors and single-stair arrangements.
04
Construction
Compartmentation, structure, concealed spaces, external walls and fire doors.
05
Escape
Evacuation strategy, route capacity and occupants' ability to respond.
06
Fire protection
Alarm, suppression, smoke control, emergency lighting and engineered solutions.
07
Hazards
Flammables, industrial processes, ignition sources and fire loading.
08
Building use
Healthcare, sleeping, care, industrial and public assembly introduce different risks.
BS 8674:2025
Three competence levels
These levels describe increasing complexity and professional capability. They are not statutory licences.
Foundation
Simpler and lower-risk contexts. Level 3 supports development of core knowledge and Foundation competence.
Intermediate
Greater technical complexity, practical assessment and reporting. Level 4 supports low and moderate-risk development.
Advanced
Complex and higher-risk environments requiring advanced judgement, experience and professional responsibility.
Actual scope always depends on individual competence and the particular premises.
Building examples
The label never tells the whole story
Offices, shops and workplaces
A small straightforward office or shop may be relatively simple. Multiple floors, mixed occupancy, complex escape, basements, high fire loads or shared systems can increase complexity substantially.
Factories and warehouses
Processes, machinery, flammables, high-bay storage, large compartments and suppression systems can require specialist industrial knowledge.
Hotels and care homes
Sleeping risk, unfamiliar occupants, limited mobility, progressive evacuation, staffing and dependency can demand significant specialist experience.
Hospitals and healthcare
Clinical processes, non-ambulant patients, multiple departments and complex compartmentation often create high assessment complexity.
High-rise residential
Common parts, compartmentation, external walls, smoke control, firefighting facilities and evacuation strategy require relevant experience.
Heritage and mixed-use
Unusual construction, protected features, hidden voids and interaction between different occupancies may require specialist input.
Specialist referral
General competence does not cover every specialist service
A fire risk assessor must recognise when separate expertise is required. General FRA competence does not automatically establish competence for FRAEW, invasive inspection, fire engineering or every specialist industrial hazard.
Recognising that work falls outside your current scope is a sign of professional competence.
For assessors
Define and develop your scope
Be able to explain
✓ Building types you regularly assess
✓ Complexity you can demonstrate
✓ Qualifications and experience
✓ Technical specialisms and limitations
Refer when appropriate
✓ Premises exceed previous experience
✓ Vulnerable occupants create unfamiliar risks
✓ Specialist external-wall or engineering input is needed
✓ Adequate information is unavailable
For Responsible Persons
How to choose a competent assessor
Ask about comparable buildings, relevant qualifications, practical experience, CPD, professional certification or registration where relevant, specialist boundaries and professional indemnity insurance. The assessor must be competent for the specific type of premises and its risks.
Frequently asked questions
Scope of fire risk assessment competence
What buildings can a Level 3 assessor assess?
Level 3 supports Foundation development and simpler low-risk contexts. It does not create automatic competence for every building described as low risk.
What buildings can a Level 4 assessor assess?
Level 4 develops Intermediate competence for low and moderate-risk scenarios. Actual scope still depends on experience and competence for the premises.
Can a Level 4 assessor assess care homes or hotels?
Not automatically. Vulnerable occupants and sleeping accommodation can add significant complexity and may require specialist experience.
Can a fire risk assessor assess high-rise flats?
Only where they can demonstrate appropriate competence and experience for high-rise residential environments.
Can any assessor carry out a FRAEW?
No. External-wall appraisal requires its own appropriate specialist competence.
Does building size determine fire risk?
No. Occupancy, use, construction, hazards, evacuation and protection systems also matter.
Should an assessor turn down work?
Yes, where the premises or technical issues exceed their competence.
Build your scope as your competence develops
Develop knowledge, gain supervised experience, expand your building exposure gradually and refer specialist work when it exceeds your competence.
