What is a fire door?
The primary function of a fire door is to act as a barrier against the passage of flames and toxic gases. These work in tandem with the building’s overall compartmentation, which is the practice of dividing a structure into “cells” to contain a fire at its point of origin.
What’s the law?
Beyond safety best practices, maintaining these barriers is a statutory necessity. In England and Wales, compliance is mandated by the Building Regulations and the Regulatory Reform (Fire Safety) Order 2005. Equivalent legislation is active in Scotland and Northern Ireland. Effective compartmentation not only protects human life along exit paths but also safeguards high-value assets and prevents catastrophic property loss.
What is a Responsible Person’s role?
The Responsible Person for a premises is tasked with ensuring a suitable and sufficient Fire Risk Assessment (FRA) is conducted. While an FRA includes a general review of fire doors, it’s usually quite limited in scope. An FRA often relies on sampling, which involves checking a few doors to get a general sense of the building's health.
While a general fire risk assessment provides a useful overview, it often relies on sampling that can overlook subtle but critical defects, such as internal frame damage or slightly misaligned closers. For a comprehensive understanding of a building’s safety, a dedicated fire door inspection survey is essential. This move beyond high-level observation is not just a matter of best practice; it is increasingly a matter of strict legal compliance.
The necessity for these detailed surveys is reinforced by the Fire Safety (England) Regulations 2022 (Regulation 10). This legislation moves beyond the broader "sampling" approach of a standard risk assessment by mandating specific, recurring inspection intervals for residential buildings over 11 metres in height:
- Communal area fire doors: These require thorough visual checks at least every three months (quarterly) to account for high traffic and potential damage in shared spaces.
- Flat entrance doors: These must undergo an inspection at least once every 12 months (annually). Because these doors lead into private dwellings, the regulations specify that these checks should be carried out on a "best endeavours" basis.
- By transitioning from a "sampling" mindset to the structured, frequent inspection regime mandated by Regulation 10, building managers ensure that critical safety features—such as intumescent seals and self-closing mechanisms—remain fully functional across the entire premises.
The difference between flat fire doors and communal fire doors
While both types of doors are important for maintaining compartmentation, the law distinguishes them as follows:
Communal area fire doors
These are doors found in shared corridors, stairways, and service risers. In residential buildings over 11 metres (typically four to five storeys), these must be checked every three months (quarterly). In buildings under 11 metres, the standard recommendation is usually every six months.
Since these are in public/common parts of the building, the Responsible Person has immediate access to inspect them at any time. These doors are high-traffic and prone to being propped open or damaged by moving furniture, so the focus is on the self-closing devices and physical integrity.
Flat entrance doors
Flat entrance doors serve as the primary barrier between a private residence and the communal escape route. Because most residential fires originate within an individual flat, these doors are crucial for containing flames and smoke within the unit of origin, preventing them from spreading to the hallways and stairwells.
The legal requirement for inspecting these specific doors is driven by the Fire Safety (England) Regulations 2022 (Regulation 10). Under these regulations, in all multi-occupied residential buildings over 11 metres in height, flat entrance doors must be checked at least once every 12 months.
It is essential to note that while the Building Safety Act 2022 introduces significant new duties for "Higher-Risk Buildings" (those exceeding 18 metres or 7 storeys)—such as safety case reports and digital records—it does not specify the frequency of fire door checks. Instead, that annual mandate stems specifically from the Fire Safety Regulations. Since any building over 18 metres is also over 11 metres, these annual checks are a mandatory part of the safety regime for all high-rise blocks.
Because these doors form the entrance to a private dwelling, they present a unique challenge for building managers compared to communal doors. The law requires a “best endeavours” approach to access. This means the Responsible Person or building manager must make documented, reasonable attempts to coordinate with the tenant or leaseholder—typically providing at least 24 hours' notice—to perform the survey.
Inspection priorities
The focus of these annual checks is to ensure the door remains a functional life-safety component. Over a year, residents may inadvertently compromise a door's integrity. The inspection specifically verifies that:
- The door fully closes into its frame from any angle using its self-closing device.
- The resident has not tampered with or removed the overhead closer.
- Intumescent strips and smoke seals have not been painted over or damaged.
- No unauthorised modifications (such as the installation of non-fire-rated cat flaps or letterboxes) have been made.
What is checked in the survey?
A professional survey should be both non-destructive and non-intrusive. It provides a detailed view of the door’s integrity without damaging the fabric of the building.
A high-quality inspection includes:
