Fire Door Surveys: Compliance, Risk and the Hidden Cost of Getting It Wrong
Updated: 6 days ago
Is it a legal requirement to have a fire door survey?
It's a question we're regularly asked. The straightforward answer is:
No — there is no general legal requirement simply to commission a specialist fire door survey.
That doesn't mean fire doors don't need to be inspected, maintained or assessed. They absolutely do.
The distinction is important.
The Responsible Person has legal duties relating to fire safety, including carrying out and reviewing a suitable and sufficient fire risk assessment and maintaining fire precautions. In certain residential buildings, there are also specific requirements for routine fire door checks.
But none of that means every Responsible Person automatically needs to purchase a specialist fire door survey.
And that distinction matters because unnecessary surveys — followed by unnecessary remedial works — can become extremely expensive.
This article looks at three issues we regularly encounter:
Competence. Risk. And independence.
Because checking whether a fire door meets a particular standard and assessing the risk presented by that door within a particular building are not necessarily the same thing.
Our Advice Before You Commission a Fire Door Survey
If you're responsible for fire safety within a building and have been advised to commission a specialist fire door survey, we'd suggest considering the following first:
Make sure you have a suitable and sufficient fire risk assessment undertaken by a competent fire risk assessor.
Establish why a specialist fire door survey is being recommended and what information it is expected to provide.
If the organisation recommending the survey also sells the survey, consider whether an independent second opinion would be appropriate.
Where the surveyor or surveying company also proposes to undertake substantial remedial works arising from its own findings, consider obtaining independent advice before committing significant expenditure.
That doesn't mean the survey or remedial recommendations are necessarily wrong.
It simply means that significant expenditure should be supported by competent, proportionate and appropriately independent advice.
Fire Doors Are Critical — But What Is Actually Required?
Let's be clear about something from the outset.
Fire doors matter.
They are an important part of a building's passive fire protection and may be fundamental to protecting escape routes, maintaining compartmentation and restricting the spread of fire and smoke.
Where the Regulatory Reform (Fire Safety) Order 2005 applies, Article 17 places duties on the Responsible Person in relation to maintaining fire precautions in an efficient state, efficient working order and good repair.
There are additional requirements within the Fire Safety (England) Regulations 2022 for relevant residential buildings.
For buildings over 11 metres in height, responsible persons are required to undertake quarterly checks of fire doors in common parts and use best endeavours to undertake annual checks of flat entrance doors. The Regulations also introduce requirements concerning information provided to residents about fire doors.
But there is an important distinction between checking a fire door and commissioning a detailed specialist fire door survey.
Government guidance describes the routine checks required under Regulation 10 as relatively simple checks and makes clear that they do not necessarily need to be undertaken by a specialist.
So the question isn't:
“Should our fire doors be checked?”
Of course they should.
A better question is:
“What level of inspection or assessment is appropriate for this building and the risks present?”
Fire Door Compliance Isn't the Same as Fire Risk
This is where things become more complicated. A specialist fire door survey will commonly examine matters such as:
the condition of the door and frame;
gaps around the door leaf;
hinges and fixings;
self-closing devices;
intumescent strips and smoke seals;
glazing;
door furniture; and
evidence of certification where available.
All of that can provide valuable information.
The difficulty comes when a departure from a current standard is automatically translated into a conclusion about risk.
An existing door may have been installed many years ago under different standards or guidance.
That does not automatically mean it is unsafe or requires replacement simply because it would not meet every detail expected of a newly installed fire door today.
Government guidance itself recognises this principle: an existing fire door does not automatically need replacing merely because it does not meet the standard that would apply to a new door installed under current Building Regulations. What matters is whether the door remains suitable from a fire-safety perspective.
That distinction is fundamental.
A measurement tells us something about a door.
It doesn't, by itself, tell us the level of fire risk within the building.
Case Study: £15,000 of Fire Door Work That Wasn't Needed
In summer 2025, we worked with a client in Croydon who had previously commissioned a fire door survey.
The resulting recommendation included approximately £15,000 of work to install new fire-rated hinges.
There was another concern: had the doors actually been required as fire doors, some potentially more significant issues had not been identified by the original survey.
But when we reviewed the building and its fire-engineered design, something much more fundamental became apparent.
With the exception of a small number of cross-corridor doors, the surveyed doors weren't required to perform as fire doors within the building's fire strategy.
The client was therefore facing approximately £15,000 of remedial expenditure on doors that, in the context of the building's design, did not require the proposed upgrades
.
That's why understanding the purpose of the door within the building's fire strategy matters just as much as measuring it.
What About Fire Door Gaps?
One of the most common findings within fire door surveys is excessive gaps around timber door leaves.
This can be important.
But again, context matters.
Consider a relatively new timber door.
It may have been correctly installed and inspected towards the end of a construction project. The building is subsequently occupied, the heating is switched on and the moisture content of the timber changes.
The timber moves.
A gap that was within tolerance when the building was completed may subsequently become larger.
That finding deserves consideration.
But does a 5mm or 6mm gap automatically tell us that the building presents a high fire risk?
Not necessarily.
To answer that question properly, we need to know much more about the door and the building in which it sits.
Case Study: From a £350,000 Quote to a Risk-Based Programme
In 2025, we worked with a client responsible for a 12-storey office building in Central London.
A fire door survey had cost approximately £20,000.
The resulting remedial quotation — provided by the same company — was approximately:
£350,000.
Many of the findings concerned excessive door gaps and had been classified as high risk.
We considered the findings differently.
Rather than looking at each door measurement in isolation, we considered the wider fire-risk profile of the building.
That included its management arrangements, fire alarm provision, sprinkler protection, smoke control, protected staircases, compartmentation, fire stopping, evacuation arrangements and other fire-safety measures.
That didn't mean the door defects should simply be ignored.
It meant asking a different question:
How significant are these findings when considered within the overall fire risk of this particular building?
Our recommendation was to prioritise the findings.
Doors protecting particularly important areas, including protected staircases and firefighting shafts, could receive greater priority, while other works could form part of a planned programme of improvement.
Same building.
Same doors.
Same measurements.
But a very different approach to managing the risk.
Compliance Findings Need Context
This is why we're cautious about simplistic pass/fail or red/amber/green approaches to fire-door inspections.
A measurement can tell you that something falls outside a particular tolerance.
That's useful information.
But the words “high risk” carry a very different meaning.
To a Responsible Person, landlord or property manager, “high risk” quite reasonably suggests something requiring urgent action.
That can lead organisations to accelerate substantial expenditure.
Before doing so, it is reasonable to ask:
High risk based on what?
Where is the door?
What does it protect?
What is its required fire-resisting performance?
What other fire precautions are present?
What are the consequences if it doesn't perform exactly as expected?
And, importantly:
Was the door actually required to be a fire door in the first place?
Fire-door inspection provides information.
Risk assessment gives that information context.
Competence Matters
Fire door inspection and fire risk assessment require overlapping knowledge, but they are not identical disciplines.
A competent fire-door inspector may have considerable expertise in door construction, installation, certification and defects.
A competent fire risk assessor considers those findings within the wider fire strategy and risk profile of the premises.
Sometimes a detailed specialist survey will absolutely be necessary.
Sometimes the fire risk assessor may identify particular doors or groups of doors requiring further specialist investigation.
And sometimes a relatively minor deviation from current guidance may be capable of being managed proportionately within the wider fire-safety arrangements.
The important thing is that the right person answers the right question.
The Potential Conflict of Interest
There is another issue Responsible Persons should consider when commissioning surveys and remedial work.
Who benefits financially from the recommendation?
Fire-safety businesses are businesses. There is nothing inherently wrong with a company providing inspection, maintenance or remediation services and making a profit from doing so.
But where the organisation identifying defects also stands to benefit financially from undertaking all of the remedial work it recommends, there is an inherent potential conflict of interest.
That does not mean its recommendations are wrong.
It does mean that where substantial expenditure is proposed, obtaining an independent professional opinion may be sensible.
The numbers can become significant very quickly.
The original version of this article considered a hypothetical building containing 800 doors. Even relatively modest individual repair or replacement costs can turn a large remediation programme into expenditure running into hundreds of thousands of pounds.
And those figures don't include the indirect costs associated with planning works, managing contractors, disruption to occupants and the time required internally to administer the programme.
When expenditure reaches that level, asking for an independent assessment of risk and priority isn't obstructing fire safety.
It's good risk management.
Independent Advice Matters
Our approach at Health, Safety & Fire Consulting is deliberately straightforward.
We don't sell the remedial works or products arising from the recommendations we make.
We don't accept referral fees, commissions or benefits in kind from contractors to whom our recommendations may lead.
Our role is to assess risk and provide independent professional advice.
If work is necessary, we'll tell you.
If we don't believe it is, we'll tell you that too.
Because good fire-safety advice isn't measured by how much work it generates.
It's measured by whether it helps you protect people and property while directing resources towards the risks that genuinely require attention.
If you've received a fire door survey or substantial remediation proposal and would like an independent fire-risk perspective before proceeding, we're always happy to have a conversation.
