Navigating Fire Door Regulations in Flats: A Comprehensive Guide

Fire doors are vital in slowing the progression of a fire; they form a crucial part of the passive fire protection system in a building. In the UK, strict policies govern the inclusion of fire doors in a block of flats. We at LFS appreciate that navigating fire door regulations can be overwhelming, so our comprehensive guide will provide all the knowledge to ensure your flat contains the necessary doors for fire protection.

What is a Fire Door?

Fire doorsets are specially designed to contain a fire within a compartment to allow residents to follow the fire evacuation strategy plan safely; they should be left closed where possible. Unlike most internal doors, fire doors are are specifically designed to resist fire and smoke for a designated period of time, as indicated by their fire ratings.

Fire Doors in Flats

Building regulations state that flat entrance door sets should offer 30 minute fire resistance.

Fire doors in a flat will be FD30 or FD60, indicating 30 or 60 minutes of fire resistance, respectively; fire doors must offer a minimum of 30 minutes of protection to allow time for residents to leave the building via the designated escape route. 

What are Fire Door Regulations for Flats?

The Fire Safety Act 2021 declares that any residential building that houses two or more sets of domestic units is within the scope of the Fire Safety Order. The Regulatory Reform (Fire Safety) Order 2005 carves out fire safety regulations of doors that must be adhered to in a flat. This is regardless of height of the building. 

From the 23rd of January 2023, it’s a legal requirement for the Responsible Person for multi-occupied buildings over 11 metres to:

  • Carry out quarterly checks of all fire doors in communal areas

  • Carry out annual checks on all flat entrance doors

  • Provide information to residents about the importance of fire doors

Responsible persons for residential buildings below 11 metres in height have a duty to put in place general fire precautions in these buildings, this duty includes making sure that all fire doors – including flat entrance doors – are capable of providing adequate protection.

Responsible persons are also required to provide residents in all residential buildings with two or more sets of domestic premises with information on fire doors within the building.

All Flat Entrance door sets should be fitted with a self-closing device and achieve as minimum FD30S to BS 476-22 or E30S to BSN 1634-1

The responsible person is the person who is responsible for the safety of themselves and others who use a regulated premises.

This is normally a building owner, or in residential properties, any other person in control of the premises. The responsible person is the person on whom most of the duties set out in the Fire Safety Order are imposed. They are responsible for conducting regular fire risk assessments and replacing broken or damaged fire safety features.

In residential buildings with storeys over 11 metres in height, responsible persons are required to undertake annual checks of flat entrance doors and quarterly checks of all fire doors in the common parts.

Fire Door Standards

  • Door Closer shuts the door

  • Door closes correctly around around the whole frame

  • There is no visible damage

  • If there are any gaps around the door frame and that seals and hinges are fitted correctly

  • Constructed using specific materials; The door frame, hinges, signage, handles, and letterboxes should all be compliant to the door set manufactures test evidence; it is also essential that a door has an intumescent fire and smoke seals

  • Glazing needs to be fire-safe. Fire-rated glazing is critical in protecting residents and the property if a fire occurs.

  • Doors must be correctly installed, close effectively from any opening angle, and move freely without slowing or grazing the floor.

  • New Fire doorset certificates must show it has been manufactured to a British Standard (BS) 476 Part 22 or the European equivalent BS EN 1634 Part 1.

Slowing Fires

A fire door can contain a fire to within a compartment by compartmentalising it and delaying its spread to the remaining building, protecting the rest of the building and the residents.


Fire doors provide an effective barrier between residents and fire, allowing precious time for evacuation and fire-fighting efforts. The extra few minutes gained can reduce the risk of injury or loss of life.

Enhanced Security

Fire doors have a solid construction designed not only to withstand a fire for a long time but also to serve as a useful security feature as resistance to external threats increases.

Fire Door Regulations FAQs

How do I know if my flat door is a fire door?

To identify a fire door, you should look for a certification label that will appear on the top edge of the door leaf. If present, the label should include the manufacturer's name, telephone number, certification number, and fire rating (FD30). 

Is it legally required to conduct a fire risk assessment for flats?

As a landlord or building owner, you must conduct a risk assessment on your flat building every 6 months. Your fire door should be inspected regularly in a high-traffic area as signs of wear will appear quicker with increased use.

How often do I need to replace my fire door?

Currently, there is no legal requirement for changing your fire door. Check the condition of your door at regular intervals, at least annually and ensure it is in good working order. Ensure you are accounting for the general wear and tear of the doors and how that might affect their effectiveness.
