Flat entrance fire doors in West Sussex: what's involved
We provide flat entrance fire doors across West Sussex, covering 9 towns and 32 postcode districts, including Crawley, Worthing and Bognor Regis.
Flat entrance door programmes in West Sussex are scheduled around residents, with access agreed in advance and each flat left secure the same day. We work with freeholders, managing agents and individual leaseholders in West Sussex, whoever is responsible for the doors under the lease.
West Sussex has a mix of buildings, from purpose-built blocks to converted houses and commercial premises. We tailor the programme to the building, not the other way round.
Who pays and who decides?
Flat entrance doors often sit on the boundary between the leaseholder's flat and the freeholder's building. Ownership depends on the lease, and leaseholder consent, landlord consent and Section 20 consultation can all come into it. We work with freeholders, managing agents, housing providers and individual leaseholders, and our responsibility guide covers the common questions.
What the rules say for West Sussex
England's framework applies in West Sussex. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.
For blocks over 11 metres in West Sussex, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.

Flat entrance fire doors questions
Do you provide flat entrance fire doors across West Sussex?
Yes. We cover all of West Sussex, including Crawley and Worthing. Surveys and written quotes are free.
Who is responsible for replacing flat front doors?
It depends on the lease. Sometimes the leaseholder owns the door, sometimes the freeholder does. Either way, the replacement has to meet the building's fire strategy, so we can work with whoever commissions it.
Can a flat door have a letterbox?
Only if the letterplate is covered by the doorset's test evidence. A standard letterplate cut into a fire door breaks the rating. Many managing agents choose external post boxes instead.
