What flat entrance fire doors in County Londonderry should include
Our flat entrance fire doors service covers all of County Londonderry, across postcode districts including BT45, BT56 and BT49.
We work with freeholders, managing agents and individual leaseholders in County Londonderry, whoever is responsible for the doors under the lease. In a block of flats in County Londonderry, 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.
Managing agents, landlords, schools, care providers, businesses and homeowners in County Londonderry can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
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.
Which fire door rules apply in County Londonderry?
County Londonderry is in Northern Ireland, where fire doors are covered by the Building Regulations (Northern Ireland) 2012 and Technical Booklet E on fire safety. Duties in non-domestic premises come from the Fire and Rescue Services (Northern Ireland) Order 2006 and the Fire Safety Regulations (Northern Ireland) 2010.
The English regulation 10 checking regime does not apply here, so the fire risk assessment sets how often doors in County Londonderry are checked. We hand over evidence that supports it.

Questions
Do you provide flat entrance fire doors across County Londonderry?
Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
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.
