Non-Domestic Properties
It’s a legal requirement that fire doors must be installed in all properties that are used for non-domestic purposes. This includes businesses, factories, commercial properties and public buildings.
Fire doors must be placed so that they form a clear horizontal or vertical escape route throughout the building.
A horizontal route can direct people to a fireproof area on a particular floor of a building or to the outside of the building
A vertical route will direct people to a stairwell
Domestic Dwellings Over Three Storeys
Any domestic dwelling that is three storeys high or over must have fire doors installed. All doors between habitable rooms and stairwells must be fire doors.
If there is an internal garage or a converted loft, these areas also need to have fire doors installed as entryways to the house.
Flats and Houses in Multiple Occupation
All blocks of flats or houses in multiple occupation (HMO) must have a fire door at the entrance point of any communal areas.
Any flats that are 4.5 metres above ground level must have fire doors fitted between habitable rooms and a fire door as the front door.
Ground floor flats are required to have a fire door at the entrance if the front door opens onto a communal area. If the internal rooms have easy access to the outside, they do not need to be fitted with fire doors.

There are no set rules for how long fire doors should last but you should consider how they are being used and how frequently they are being inspected. Despite being sturdy and often built for commercial use, they are still susceptible to wear and tear over time.
The lifespan of a fire door can vary between different properties depending on a variety of factors:
Exposure to fire damage
Damage from mis-use or force
Frequency of use over time
Natural deterioration
Fire doors are made up of different components and materials which can affect the performance of the door and how much protection it offers.
Core structure - all fire doors have a solid core but this can degrade over time, which affects the level of protection and safety.
Delamination - layers of materials within the door can start to separate, typically due to use over time or exposure to the elements.
Visible damage - forced entry or vandalism may create obvious damage to the fire door, which can create a weakness in the structure. While this can sometimes be repaired, it could be an opportunity for a replacement.
