Why are fire doors important?
Fire doors play a crucial role in protecting the people and contents of your building.
Made from fire-resistant materials, fire doors aim to form critical ‘fire stopping’ pockets by being strategically positioned around your building. This then stops uncontrolled fires from spreading, keeping escape routes clear, and buying time for evacuation.

Different types of fire doors
Different types of doors use different materials such as steel or timber.
In addition, fire doors are rated by the number of minutes they’re able to provide protection for, making them relevant to different applications:
- FD30 and FD60 are generally used in residential settings
- FD90 and FD120 doors offer higher protection for industrial or high-risk areas
Fire doors can also be rated for smoke control (e.g. FD30S), and must be fitted with the correct seals, hardware, and self-closing mechanisms to maintain performance. Every component must work together to meet fire safety regulations and provide effective protection.

Fire doors should be installed in strategic locations throughout a building to limit the spread of fire and smoke. Common areas include stairs, corridors, and between compartments or rooms that may contain hazardous materials.
Yes, landlords must install fire doors where required by law. In certain properties, such as multi-occupancy buildings, fire doors are mandatory for tenant safety. Landlords are legally responsible for ensuring that fire doors meet fire safety regulations and that they are properly maintained throughout the tenancy. Non-compliance can result in significant fines or legal consequences.
Yes, smoke seals are required on fire doors. Smoke seals, plus intumescent strips are used to prevent smoke from spreading through gaps around fire doors. This is essential, as smoke spread can be just as dangerous as fire.
Faulty fire doors pose significant risks, including the potential spread of fire and smoke throughout a building. If a fire door is damaged, improperly fitted, or malfunctioning, it may fail to contain the fire. This could result in greater damage to property, injury, or loss of life. Faulty fire doors undermine the effectiveness of a building's entire fire protection system.
Yes, UKCA (UK Conformity Assessed) and CE markings are mandatory for fire doors. These markings indicate that the door has been tested and meets relevant fire safety standards. The marking is typically found on the door frame or door leaf, along with additional information such as the manufacturer's details, the fire rating, and the testing standards it meets. The presence of these marks ensures the door is legally compliant.
