Fire door installation in Sussex: what the 2022 regulations mean for you
Published 2025-11-18 · by Joshua Lewis
Since January 2023, the Fire Safety (England) Regulations 2022 require responsible persons in multi-occupied residential buildings to carry out regular fire door checks. If you own flats, a HMO or manage a block in Sussex, here's what that actually means.
Who the rules apply to
The regulations apply to the 'responsible person' for a multi-occupied residential building above 11 metres (quarterly flat-entrance door checks) and any multi-occupied residential building (annual common-area door checks). In practice: landlords of flat blocks, HMO operators, managing agents, and building owners.
What a compliant fire door install looks like
- Door leaf rated FD30 or FD60 (30 or 60 minutes fire resistance)
- Installed to the manufacturer's installation data sheet
- Correct intumescent strips and smoke seals in the frame or door edge
- Gap tolerances within spec — typically 2–4mm around the leaf, 8–10mm under
- Certified hinges (minimum 3, CE-marked, fire-rated)
- Correct closer, correctly adjusted
- Signage where required
What we provide with every fire door install
Photos of every install, gap measurements documented, data sheet reference, signed installer record. That's exactly what a managing agent or fire-risk assessor wants to see at inspection. We're working toward BM TRADA Q-Mark certification — the UKAS-accredited scheme that's become the industry gold standard post-2022.
Common questions
Is BM TRADA certification legally required?
No — it's not a legal requirement, but it's the most widely recognised third-party assurance and many managing agents and insurers now specify it.
Can you replace just the door, or does the frame need doing too?
If the frame is in good condition and compatible with the new door's intumescent spec, frames can often stay. We assess and tell you honestly.
