Fire door requirements

There is no single universal fire-door specification or checking interval for every building. Requirements come from the building design, fire-risk assessment, applicable legislation and the intended role of each doorset.

Direct answer

Which laws affect fire doors?

For occupied premises within scope, the Fire Safety Order requires appropriate general fire precautions and maintenance of relevant systems in efficient working order and good repair. The Fire Safety Act 2021 clarifies that flat entrance doors fall within the Order for buildings containing two or more domestic premises.

Not one specification

What rating, seals and closer are required?

A door commonly described as FD30 or FD60 is associated with 30 or 60 minutes of integrity performance, but the required rating depends on the compartment line and design. An “S” suffix is commonly used where smoke control is also required. The correct leaf, frame, seals, glazing and hardware must be supported as a compatible arrangement.

Do not upgrade or replace components solely from a generic internet checklist. Establish the intended door role and available evidence, then use competent advice where a change could affect performance, accessibility or escape.

Occupied buildings

Checking, maintenance and records

The frequency and depth of checks should reflect risk, use, damage history, manufacturer information and applicable legal duties. A frequent operational check can identify obstruction, visible damage and failed closing; a detailed doorset inspection examines evidence and components more closely.

For multi-occupied residential buildings in England over 11 metres, responsible persons must use best endeavours to check flat entrance fire doors at least annually and check communal fire doors at least every three months. Other premises still need risk-based inspection and maintenance even where those precise intervals do not apply.

  • Record door identity, location and intended role
  • Separate simple checks from technical inspection
  • Prioritise failures affecting closure, retention, fire or smoke control
  • Use compatible repairs and retain evidence
  • Verify completed remedial work rather than merely closing an action

Frequently asked questions

Fire door requirements FAQs

These answers provide general guidance for England. The correct conclusion depends on the door, building, design evidence and people at risk.

Must every fire door provide 30 or 60 minutes?

The required performance depends on its location and the building design. FD30 and FD60 are common descriptions, but they are not the only possible specifications.

How often must fire doors be checked?

Defined quarterly and annual duties apply to certain residential buildings over 11 metres. Elsewhere, frequency should be risk-based and sufficient to keep doors effective, with manufacturer and sector guidance considered.

Do old fire doors have to be replaced with new certified doors?

Not automatically. Government residential guidance says existing doors should be assessed against the standard at installation and current risk; absence of modern certification alone does not prove the door is unfit.
