Questions from Merthyr Tydfil clients

Does regulation 10 apply in Merthyr Tydfil?

No. Merthyr Tydfil is in Wales and regulation 10 is English law. The Fire Safety Order 2005 still requires fire doors to be maintained, and many Welsh landlords follow the same quarterly and annual routine as good practice.

How quickly can you inspect fire doors in Merthyr Tydfil?

It depends on the number of doors and access. Tell us what you need and we will give you the earliest date when you call, and confirm it in writing.

Why do gaps open up over time?

Hinges wear and drop, frames shrink or move, leaves warp, and doors are sometimes planed after flooring changes. Each needs a different repair.

What gap is allowed around a fire door?

Most guidance and manufacturers' evidence expect gaps of about 2 to 4 mm at the head and edges, with 3 mm as a practical target. The door's own certification or test evidence takes precedence if it states a different figure.
