About our pre finished fire doors
Thirteen FD30-certified styles in oak, white, and black — all finished before they leave the factory. Oak doors get a lacquer. White and black get paint. Applied in controlled conditions, not on a building site, which is why the finish is consistent and holds up better against moisture and daily wear than anything applied on-site. No painting. No staining. No varnishing. Hang the door.
Pre-finished fire doors are built from fire-resistant materials including timber and gypsum-based composite cores, with intumescent strips that expand under heat to seal the gap between door and frame. They work in homes, offices, and commercial settings. Available sizes are listed on each product page. All prices include VAT, free mainland UK delivery on every order, and a 10-year warranty as standard.
FAQs
Is it worth buying pre-finished doors?
Yes. You save time on site and avoid the cost of paint, primer, or varnish. The factory finish resists moisture and scuffs better than anything brushed on by hand. For anyone fitting multiple doors, that adds up quickly. The FD30 certification stays intact — the coating is applied in a way that doesn’t affect the fire rating.
What does pre-finished internal door mean?
The door arrives already painted, lacquered, or stained — finished in a factory before packaging and shipment. No sanding, no priming, no topcoat needed. Just hang it. Pre-finished fire doors carry the same FD30 certification as primed or unfinished options. The factory finish doesn’t affect the fire rating.
How much does a new fire door cost?
Our pre-finished fire doors start at £164.00 for the Oak Flush Fire Door and go up to £260.00 for the Cobham Black Oak Prefinished FD30. All prices include VAT and free mainland UK delivery. Each product page shows available sizes and full pricing.
