Getting loft conversion fire doors right in Chorley
For property owners, landlords and managing agents in Chorley, we offer loft conversion fire doors with one team for the survey, the product and the installation.
Buildings in and around Chorley range from small offices to schools 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.
For homes in Chorley, we match fire doors to your existing style wherever certified options allow. A loft conversion in Chorley that adds a new storey often brings a building control requirement for fire doors on rooms off the stair.
Why loft conversions trigger fire doors
A two-storey house usually lets people escape from upstairs windows. Once a loft room is added, the top floor is too high for that, so the stair becomes the escape route and has to be protected from the ground floor up. That is why building control often asks for fire doors on rooms off the stair, including existing ground and first-floor rooms, not just the new loft room.
As standard, the work covers:
- Frame repairs or new linings where needed
- Check of which openings need fire doors
- Work coordinated with your builder
- FD20 or FD30 doors in your chosen style
What the rules say for Chorley
In Chorley, as elsewhere in England, the starting point is the Fire Safety Order 2005: whoever controls a workplace or the shared parts of a residential block must make sure its fire doors work. When doors are replaced, the Building Regulations and Approved Document B set the standard the new work has to meet.
Blocks above 11 metres have a specific routine under regulation 10 of the Fire Safety (England) Regulations 2022: quarterly checks of communal fire doors and annual best-endeavours checks of flat front doors. If your Chorley building is a higher-risk building under the Building Safety Act 2022, we confirm the approval route with the Principal Accountable Person before any work is ordered.

Questions from Chorley
Is Chorley within your coverage area?
It is. We cover Chorley in Lancashire and neighbouring towns such as Leyland. There is no charge for the survey.
Do I need to be there for the survey?
Someone needs to give us access to the doors. For blocks and commercial buildings, a caretaker or site contact is fine; for HMOs and homes, we agree a time with you or your tenants.
Do all my doors need to be fire doors after a loft conversion?
Usually the doors from habitable rooms onto the stair do, on every floor. Bathrooms are often excluded. Building control decides for your house.
Can I just add intumescent strips to my existing doors?
Generally no. A standard internal door is not a fire door, and strips alone will not make it one. Existing doors need to be replaced with certified fire doors.
