What flat entrance fire doors in Gwynedd should include
We provide flat entrance fire doors across Gwynedd, covering 44 postcode districts from LL23 to LL78.
In a block of flats in Gwynedd, 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. We work with freeholders, managing agents and individual leaseholders in Gwynedd, whoever is responsible for the doors under the lease.
Managing agents, landlords, schools, care providers, businesses and homeowners in Gwynedd can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
Why flat front doors matter so much
In most blocks the fire strategy relies on each flat containing a fire for long enough that other residents can stay put or leave safely. The flat entrance door is the barrier that makes that work. A door without a working closer, with a missing seal or with a non-fire-rated letterplate can let smoke into the corridor within minutes.
In England, regulation 10 of the Fire Safety (England) Regulations 2022 asks responsible persons in residential buildings above 11 metres to use best endeavours to check flat entrance doors at least every 12 months. Rules differ in Wales, Scotland and Northern Ireland; our guide to the regulations for flats sets them out.
The regulations behind fire doors in Gwynedd
Because Gwynedd is in Wales, we work to the Building Regulations as they apply in Wales and to the Welsh version of Approved Document B. The responsible person duties under the Fire Safety Order 2005 still apply to workplaces and common parts.
England's fire door checking rules for tall residential buildings do not apply in Wales, so the checking frequency for doors in Gwynedd comes from your fire risk assessment.

Questions
Do you provide flat entrance fire doors across Gwynedd?
Yes. We cover all of Gwynedd. Surveys and written quotes are free.
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.
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.
