Certified fire doorsets in Dorset, done to the evidence
Our certified fire doorsets service runs throughout Dorset. Main towns include Bournemouth, Poole and Weymouth, and we cover the smaller places in between.
Doorsets suit refurbishment programmes in Dorset, where several openings can be measured, ordered and fitted in one planned sequence. Every doorset we fit in Dorset is handed over with its certificate reference and photographs of the frame fixing and gap sealing.
Wherever your building is in Dorset, the fire safety duties come from national rules, and our installation standard is the same.
How is a doorset installed?
The opening is prepared to the size and tolerances in the manufacturer's instructions. The frame is fixed with the specified fixings at the specified centres, packed where needed, and checked for square, plumb and twist. The gap between frame and wall is then sealed with a material covered by the evidence, which BS 8214:2026 now describes in more detail. Finally the leaf is adjusted, the closer is set and the assembly is tested before the architraves go on.
Fire door law for Dorset properties
England's framework applies in Dorset. Approved Document B guides the fire performance of new and replacement doors under the Building Regulations 2010. Day-to-day duties sit with the responsible person under the Fire Safety Order 2005, and for multi-occupied residential buildings, the Fire Safety (England) Regulations 2022 add duties such as giving residents information about fire doors.
For blocks over 11 metres in Dorset, those regulations require communal fire door checks at least every three months and best-endeavours flat entrance door checks each year. In higher-risk buildings, building work is overseen by the Building Safety Regulator, so we check whether approval is needed before starting.

Prices for certified fire doorsets in Dorset
If you need a budget figure first, the guide for certified fire doorsets is £650–£1,300 for an FD30 doorset and £850–£1,800 for FD60, supplied and fitted, ex VAT. We firm that up after a survey, pricing each door separately so you can see where the money goes.
Common questions
Do you provide certified fire doorsets across Dorset?
Yes. We cover all of Dorset, including Bournemouth and Poole. Surveys and written quotes are free.
Are doorsets more expensive than a leaf?
The product costs more, but the labour is often lower and the result is better evidenced. Where a frame would need replacing anyway, a doorset is usually the better value.
How long do doorsets take to arrive?
Lead times depend on the manufacturer, size, finish and ironmongery. Standard sizes can be quick; bespoke sizes and finishes take longer. We give you the lead time with the quote and confirm it at order.
