Current regulations for certified fire doors

Updated: March 2021

Why is it important to comply with fire door regulations?

A fire door plays a vital role in the safety and fire protection of buildings. Since a fire door is a functional item that is a necessity in all buildings, it has to meet several specified regulations. These include accessibility, sound, ventilation, fire safety and safety glazing. Fire door regulations are meant to ensure that fire doors are designed and fitted in accordance with the relevant laws.

Almost all buildings in the UK are required to have at least one fire door. Here are some of the more important fire door regulations that apply across the UK:

Where must fire doors be fitted?

There is a requirement for every building to be divided into different compartments. Escape routes including corridors and staircases should be protected. In a domestic dwelling that has two levels or more, any door that leads to the stairwell at any level has to be a fire door if it is leading into a habitable room.

A fire door should also be fitted between a house and an integral garage. In mixed-use buildings, fire doors should be used between the residential and business elements.

Required fire resistance period

Where a compartment wall separates two separate buildings, the fire door and the wall that contains it have to have the same resistance period. The resistance period of the fire door cannot be lower. The minimum fire resistance period is 60 minutes. In any other situation, 30-minute fire doors (FD30) are allowed.


Any fire door in a non-domestic building should have the correct signage. It should have signage on both sides. The sign should indicate clearly that it is a fire door. There may be other instructions such as “Keep Locked” or “Keep Closed”. Standard signs can be purchased from a fire door dealer.

Smoke seals

These are recommended where a fire door approaches or protects an escape shaft such as a staircase or corridor or where a fire door is between a private area and a common space. A good example is the front door of a flat. Smoke seals should also be used on doors in corridors leading to dead ends. Where a smoke seal is to be used, the threshold gap is should not exceed 3 mm.

Glazing safety

If a fire door is located less under 15 cm from the floor level, it has to have a safety glass. This is a requirement in all buildings, domestic or non-domestic.

Code for Sustainable Homes

On top of the different regulations, there are also codes and standards that fire doors should comply with. They have to meet a criterion known as Code for Sustainable Homes. When it comes to procurement, there are also several sourcing regulations.

Government legislation changed on 1st November 2019, and all new HAG Ltd. fire doorsets are tested and compliant to the latest standard BS EN 16034:2014 & CE Marked to BS EN 13241-1:2003. Products tested to 2008 certification are prohibited by law. For more information visit our UKCA / CE compliance page.

The importance of the ‘doorset’

It is important to remember that a fire door is an element of a whole system called a  “doorset”.  BS EN 12519 defines a doorset as “supplied complete with all essential parts from a single source and for which the main intended use is the access of pedestrians.”

Following the tragedy of Grenfell Tower in June 2017, the DHF / Secured by Design / Fire Industry Association published A Guide for Selecting Flat Entrance Doorsets (PDF download)   HAG recommends that all specifiers read this.  This makes the point that there is no conflict between fire and security with Building Regulations ADB (fire) and ADQ (security) carrying equal weight with neither taking precedence over the other. It explains why only factory produced doorsets can meet both ADB and ADQ.

Final advice

This page is designed as an introductory guide to a complex subject.  HAG advises specifiers to seek approval of the ‘Responsible Person’ as defined by Fire Safety Order (FSO) 2005 to confirm that the fire doorset meets the building’s fire safety requirements.
