Getting flat entrance fire doors right in Horsham
We provide flat entrance fire doors in Horsham (RH12 and the surrounding postcodes), from the first survey through to a documented handover.
Buildings in and around Horsham range from schools to low-rise blocks of flats and family homes after loft conversions. Whatever the building, the standard is the same: certified products, correct gaps, seals and closers, and a frame sealed to the wall.
In a block of flats in Horsham, each flat's front door is what keeps smoke out of the shared corridor, which is why a working closer matters as much as the door. Flat entrance door programmes in Horsham are scheduled around residents, with access agreed in advance and each flat left secure the same day.
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.
Each installation includes:
- Survey of door, frame, threshold and ironmongery
- Intumescent and smoke seals, threshold set to evidence
- Viewer, numerals and security hardware within the certification
- Certified FD30S doorset in timber or composite
The regulations behind fire doors in Horsham
Fire doors in Horsham fall under English rules. New and replacement doors are covered by the Building Regulations 2010 and Approved Document B. In workplaces and the common parts of blocks, the Regulatory Reform (Fire Safety) Order 2005, as clarified by the Fire Safety Act 2021, puts the duty on the responsible person to keep fire doors suitable and maintained.

Higher-risk buildings of at least 18 metres or seven storeys also come under the Building Safety Act 2022, where works may need approval from the Building Safety Regulator.

Common questions
Do you cover RH12 and nearby postcodes?
Yes. We cover Horsham including RH12, and nearby towns such as Crawley and Horley. The survey and written quote are free.
Can you work from an existing inspection report for my Horsham building?
Yes. Send it over and we can often price straight from it, then confirm on site. We report back against the same door references so you can close actions off.
Can residents choose the colour of their front door?
Often, within the range the doorset manufacturer offers and within any rules the freeholder sets for the corridor. Factory finishes are better than site painting, which can clog seals and hide labels.
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.
