The service
What is a fire stopping survey?
Fire stopping is the passive fire protection installed within and around service penetrations, construction joints and gaps in fire-resisting walls, floors and ceilings.
Its purpose is to maintain the fire resistance of compartmentation at every point where a penetration has been made so fire and smoke cannot pass through the structure at these points of potential weakness. A fire stopping survey is a specialist inspection that systematically identifies where fire stopping is absent, incorrect, damaged or incompatible with the construction it protects. Where buildings have complex service installations or a history of refurbishment, intrusive surveys open up concealed voids and risers at representative sample points, with all openings documented and made good afterwards.
Our surveys go beyond identifying obvious breaches. A critical element is the evaluation of product compatibility: fire stopping must be installed as part of a tested and assessed system using products with UKAS-accredited third-party test evidence appropriate to the specific construction and service type. Generic or untested products provide no reliable assurance of fire resistance and we identify these deficiencies clearly with specific remediation guidance.
Common failures
- Missing fire stopping at penetrationsServices installed through fire-resisting elements with no fire stopping in place, often found after maintenance or refurbishment works.
- Wrong product specified or installedNot all fire stopping products are compatible with all construction types. Incorrect products provide no reliable fire resistance.
- Incorrectly installed intumescent productsIntumescent collars, pillows and wraps installed incorrectly cannot be relied upon to perform in a fire.
- Damage from subsequent worksPreviously installed fire stopping damaged by later maintenance works, a very common finding in building services risers.
- Oversized penetrationsHoles significantly larger than the service passing through them, with gaps filled informally using unsuitable materials.
Why it matters
Why fire stopping is critical
Fire stopping is the last line of defence in compartmentation. A fire-resisting wall or floor is only as effective as the penetrations through it and a single unsealed or incorrectly stopped penetration can provide a direct pathway for fire and smoke to spread between compartments, defeating the entire strategy and threatening escape routes.
Research into building fires consistently identifies fire stopping failures as a significant contributor to fire spread. Since the Grenfell Tower Inquiry, fire stopping is subject to far greater regulatory scrutiny and owners who cannot demonstrate their buildings have been surveyed and remediated face growing exposure to enforcement action and insurer pressure.
The framework
Regulatory context
The legislation, standards and guidance that make fire stopping a documented legal obligation.
Regulatory Reform (Fire Safety) Order 2005
The Responsible Person must ensure fire safety measures, including passive protection, are maintained in effective working order across non-domestic premises and residential communal areas.
Fire Safety Act 2021
Extended duties to the structure, external walls and flat entrance doors of multi-occupied residential buildings, making fire stopping in these elements a direct legal obligation.
Fire Safety (England) Regulations 2022
Additional duties for responsible persons in multi-occupied residential buildings over 11 metres, including quarterly fire door checks.
Building Safety Act 2022
A building safety regime for higher-risk buildings requiring accountable persons to maintain Safety Cases that demonstrate passive fire protection measures.
Building Regulations 2010 (Approved Document B)
Fire safety requirements for the design and construction of buildings in England.
BS 8674:2025
The competency framework for individual fire risk assessors. All our assessors are aligned with BS 8674:2025.
NFCC guidance
The National Fire Chiefs Council has published specific guidance on the assessment of fire stopping in existing buildings.
Insurance requirements
Many property insurers now require evidence of fire stopping surveys as a condition of cover for high-risk building types.
Scope of survey
What our survey covers
A systematic inspection of every point where compartmentation can be breached.
How we work
Our survey process
A four-step approach from scoping to verification, closing the loop on every breach.
- 01
Initial assessment
We review available building information, agree the survey scope and methodology and plan access to all relevant areas before we attend.
- 02
Physical survey
Our passive fire protection specialists carry out a systematic inspection, documenting every breach with photographic evidence and precise location references.
- 03
Survey report
A comprehensive report maps all fire stopping deficiencies, with remediation recommendations and the correct product specifications for each situation.
- 04
Verification
Following remediation by a specialist contractor, we carry out post-works verification to confirm every breach has been correctly addressed.
Sectors
Who we survey for
Survey programmes matched to the service complexity and compliance demands of your sector.
Residential buildings
Multi-occupied blocks, particularly those subject to Building Safety Act requirements, have a particular need for documented fire stopping surveys.
Commercial
Office and commercial buildings with complex service installations or refurbishment histories commonly have significant fire stopping deficiencies.
Healthcare
Hospitals and care homes with extensive services infrastructure require regular inspection to maintain compartmentation integrity.
Industrial
Factory and warehouse buildings with complex mechanical and electrical services need surveys at service penetrations throughout.
Education
School and college buildings, particularly older stock with extensive infrastructure, benefit from systematic survey programmes.
Developers and contractors
Surveys at practical completion to ensure the building is handed over in a compliant, documented condition.
Why Southport Fire Risk Assessment
Identify, specify, verify
Product knowledge
Our surveyors have current, in-depth knowledge of passive fire protection products and systems, enabling accurate assessment of compatibility and correct installation.
Remediation specification
We do not just identify breaches. We specify the correct remediation for each situation, giving contractors the information they need to remediate effectively.
Verification service
Our post-remediation verification closes the loop, confirming works have been completed to the required standard and providing the documentation to prove it.
