Surplus Doors UK: Fire, Internal and External at Trade Prices
Doors are the single biggest surplus category by unit count. Every contract over-orders internal doors by 2–5%, showrooms rotate displays quarterly, and FD30/FD60 fire door specs change often enough that certified stock lands on the surplus market monthly.
What to check on a surplus fire door
- Intumescent strip intact around all four edges
- Certification plug (top edge) still legible
- No modifications — even a letterbox voids certification
- Original data sheet available from the seller

Frequently asked questions
+Can I re-hang a surplus fire door on any frame?
Only if the frame matches the door's original certification (same manufacturer or a compatible tested pairing). Mixing brands voids certification.
+What's a 'shop-soiled' door?
Cosmetically marked but structurally new. Fine for paint-grade internal doors; check carefully for external and fire-rated.
