Fire doors · Modifications
Can you modify a fire door?
Short answer
Potentially, but not by assumption. Drilling, cutting, glazing, adding hardware or changing a component can affect the evidence that supports the doorset.
What changes the answer
- what modification is proposed
- the exact leaf and frame system
- the hardware or product being added
- location and size of cut-outs
- wiring route
- existing tested or assessed evidence
- manufacturer instructions.
What to check on site
- photograph existing hardware
- identify tags and system
- mark the proposed location
- provide product data for the new hardware
- check whether the door has already been modified.
What to do next
Send the doorset details and the proposed modification before work starts. Do not treat a neat-looking modification as a supported one.
