Fire door hinges

Updated: October 2026

You are about to replace the hinges on a flat entrance door, or on a door labelled FD30 or FD60, and amazon.co.uk is full of highly rated butts with no grade on the page. Fire door hinges are the hinge named on that door's evidence, UKCA or CE marked to BS EN 1935, with fire digit 1. None of the eleven packs print that mark, so none is a fire-door hinge here. The top pick and the best value are ordinary internal butts. Bedroom fitting stays on [how to fit door hinges](/hub/door-and-window-security/door-hinges/sub/door-hinges-how-to-fit). The shelf is the [door hinges comparison](/hub/door-and-window-security/door-hinges). Peter F. used UK fire-door hardware guidance and the kept listings, updated October 2026. We did not test a doorset. A qualifying purchase can earn a commission at no extra cost to you.

What the hinge must show

Approved Document B treats the leaf, the frame and the ironmongery as one doorset. ASSA ABLOY's UK guidance says fire-door hinges must be UKCA or CE marked to EN 1935. Digit 4 has to be 1 before the hinge is described as suitable for a fire or smoke door, and it still needs an EN 1634 test on that door type. Grade 13 means a 120 kg test door at 200,000 cycles. The XFORT packs state 40 kg or 80 kg and no BS EN 1935 line. A review of the 3 inch pack says they are not marked for single-axis fire doors. A review of the GBACHOOSE ten-pack says a carpenter fitted them to an FD30 door and they warped. Ordinary doors are the door hinges buying guide.

Three hinges and intumescent pads

Fire-door guidance asks for at least three hinges, because they hold the gaps as the leaf moves. Two hinges on a tall FD30 door are a different specification. A closer adds notional mass. The DHF/GAI code counts about 20 percent more for a standard closer and about 75 percent more with backcheck. Intumescent pads are not automatic. A hinge certificate may call for 1 mm or 2 mm pads. A door sheet may not. Armadah's note on a Strebord 44 FD30 core, for leaves under 2,670 mm, is an example of a sheet that may not require pads, while the hinge evidence still might. If you have the door sheet, it wins. If you do not, fit the pads the hinge test used.

Screws and what a check looks for

The DHF/GAI code wants at least a No. 8 screw, 30 mm long, into timber. A review of the 3 inch XFORT pack describes screws of about 25 mm. Short screws on a fire door are a defect a check is meant to catch. GOV.UK guidance on the Fire Safety (England) Regulations 2022 looks for loose or missing hinge screws, gaps generally not more than about 4 mm at the top and sides, and a closer that shuts the door. That is an inspection list, not permission to buy an unmarked hinge. For a non-fire internal door, use the best door hinges page.

What you must not do

Do not fit a rising butt or a spring hinge to clear a carpet on a fire door. The BWF Fire Door Alliance example specification does not permit them. The Leshmido pack fails twice: no mark, and the wrong type. Do not plane a fire door so a thicker hinge will sit. Wickes says not to plane a fire door, because the leaf, the frame and the ironmongery are one doorset. Do not treat a ball-bearing title as a fire rating, and do not treat polished brass as allowed because it matches the old colour. The best value pack is unmarked brass, so it is out. Do not move the hinges to the 150 mm domestic marks if the certificate shows different centres. On a flat entrance door, stop and use a competent fire-door installer.

Common questions

How many hinges does a fire door need?
At least three. The hinges keep the leaf in line so the gaps stay as tested. Two hinges are a different specification. A door closer increases the notional mass, by about 20 percent for a standard closer and about 75 percent with backcheck in the DHF/GAI code, so the hinge grade has to cover the closer as well as the leaf.
Do I always need intumescent pads?
No. Fit them when the hinge test or the door sheet says so. A hinge certificate may require 1 mm or 2 mm pads, while a particular FD30 sheet may not, including some Strebord 44 leaves under 2,670 mm. If you have the door sheet, follow it. If you do not, use the pads the hinge test used rather than leaving them out.
Can I fit a rising butt to clear a carpet on a fire door?
No. BWF's example specification does not permit rising-butt or spring hinges on a fire door. A carpet clearance is a reason to look at the door and the floor with a competent person, not a reason to fit a lift-off hinge. The rising-butt pack in this set is unmarked as well.
What should be stamped on the hinge?
Look for UKCA or CE marking to BS EN 1935, and a classification code whose fire digit, digit 4, is 1. Grade 13 is a 120 kg test door at 200,000 cycles. Grade 11 is 80 kg. The hinge should also be one the door evidence names. A stated 40 kg or 80 kg without that code is not the stamp.
Who should replace hinges on a flat entrance door?
A competent fire-door installer. A flat entrance door is a fire door in the block, and the check for loose screws and gaps of more than about 4 mm is an inspection, not a cue to buy an unmarked three-pack. If you cannot see the door's hardware evidence, do not guess it from a product title.
