Can You Put a Coat Hook on a Fire Door?
TL;DR
Not without checking first. A hook is only acceptable when the door's certification or the manufacturer's data sheet allows that kind of surface fixing, and the door still closes, latches and seals afterwards.
Over-the-door hangers are the most common problem: they sit in the gap at the head of the door, can crush the seals there and often stop the door closing on its own.
Screwed-on hooks put holes in the leaf. Long screws, hooks near the edges and holes left behind when hooks are removed can all become defects.
Coats hung on doors in escape routes add things that burn exactly where people need to get out.
Hooks already fitted are a routine fire door remedials job: remove them, repair the holes to the door's evidence and give staff somewhere else to hang their coats.
Walk round almost any office, school or clinic in winter and you will find them: a row of coat hooks screwed to the back of a meeting room door, a chrome over-door hanger on the staff toilet door, a bag hanging off the door to the plant room. Nobody fitted them to cause a problem. But when the door is a fire door, a hook can quietly stop it doing its job, and it will usually be picked up on the next check.
Can you put a coat hook on a fire door?
Only when the door's evidence allows it. A fire door is tested and certified as a complete assembly, and anything fixed to the leaf needs to fall within what the certification or the manufacturer's data sheet permits. Some manufacturers allow small, lightweight surface fixings with short screws; others do not. If the evidence does not cover it, or you cannot find the evidence, do not fit the hook. Find another place for coats.
Why are hooks a problem on fire doors?
There are four everyday reasons:
They stop the door closing. A hanger over the top edge, or a heavy coat on a hook, can hold the door just off the latch. A door that does not close fully will not hold back smoke or fire.
They damage the seals. Over-door hangers sit in the gap at the head of the door, right where the intumescent strip and smoke seal often are.
They put holes in the leaf. Every screw goes into the door's core. Screws that are too long, or fixed near the edges, glazing or ironmongery, can affect how the door performs.
They add fire load. Coats and bags are combustible, and on a door in a corridor or stair they are hanging in the route people use to escape.
Each of these is the kind of thing a fire door inspection records as a defect.
Are over-the-door hangers allowed on fire doors?
Generally they should be avoided. The hook part wraps over the top edge of the leaf and sits in the gap between the door and the frame head. That gap is set within tight limits so the door can close and the seals can work. A hanger takes up that space, can rub or crush the intumescent strip and smoke seal, and is a common reason a door stops latching. Because they need no tools, staff fit them without anyone knowing. Our article on fire doors and the gaps around them explains why those gaps matter.
What should you check before fitting a hook to a fire door?
Before anything is screwed on, check:
Is it a fire door? Look for a label, plug or certificate on the door edge. Our article on how to know if a door is a fire door explains where to look.
What does the data sheet say? Look for guidance on surface-mounted fittings, fixing types and screw lengths.
Where would it go? Mid-leaf, clear of the edges, the seals, any vision panel and the lock, closer and hinges.
Will the door still work? With a coat hanging on it, the door should still close and latch from any open position, without help.
Is the door in an escape route? If so, coats are better kept off it altogether.
If any of these cannot be answered, put the hook on a nearby wall or provide a coat stand instead.
What if coat hooks are already fitted to your fire doors?
This is far more common than new requests, especially in older offices and schools. The fix is straightforward:
Take off over-door hangers and check the head of the door for crushed or missing seals.
Remove screwed-on hooks that the door's evidence does not cover.
Repair the holes using a method and materials the door's evidence allows. Filler alone is not always enough, depending on the size and depth of the hole. Our article on holes drilled through a fire door explains why.
Check the door still closes, latches and holds its gaps, and that the seals are intact.
Give people an alternative, such as wall hooks or a coat stand away from the escape route, or the hooks will come back.
Hook removal, hole repairs and seal replacement are all everyday fire door remedials items, and they are quick to close out when they are grouped with other defects on the same floor.
Where should staff hang coats instead?
On a wall or a free-standing coat stand, kept away from doors and out of corridors and stairs that form escape routes. In cloakrooms and staff rooms, a wall-mounted rail is the simplest answer. If coats keep appearing on doors, it is usually a sign there is nowhere else to put them, so it is worth solving that at the same time as removing the hooks. The same thinking applies to seasonal decorations; our guide to Christmas decorations and fire doors covers it.
What should you record?
For each door, note the location and reference, what was found (hooks, hangers, holes), what was removed, how the holes were repaired and to what evidence, who did the work and the date, with before and after photographs. Then confirm the door closes, latches and seals, and check it again on the next routine fire door inspection. Our guide to fire door records sets out what to keep.
What to do next: how Protest ES Ltd helps
Protest ES Ltd works with facilities managers, managing agents and FM providers across commercial, education, healthcare and public sector estates. We don't simply identify compliance issues. We help clients close them:
Fire door inspections that record hooks, hangers, unauthorised fixings and damaged seals, door by door
Fire door remedials that remove unauthorised fittings, repair holes to the door's evidence and replace damaged seals, with records for every door
Fire door installation of replacement leaves and doorsets where a door is too damaged to repair
BM TRADA Q-Mark certification for fire door installation, maintenance and inspection
One visit, more disciplines. Most FMs use separate contractors for fire doors, fire stopping and electrical testing, each with its own access, programme and paperwork. Protest ES Ltd delivers fire door work, passive fire protection, including fire stopping and fire compartmentation, and electrical compliance on the same visit: one contractor, one programme, one set of records across every site.
If hooks, hangers and old fixings are turning up on your fire doors and you want them closed out properly, get in touch with our team or visit Protest ES Ltd.

Frequently asked questions
Can you screw into a fire door?
Only where the door's evidence allows it, using the fixing type and screw length it permits. Every screw goes into the door's core, so unplanned holes can affect how the door performs in a fire. If the evidence does not cover the fixing, do not make the hole.
Can you use adhesive hooks on a fire door?
Stick-on hooks avoid drilling, but they still add weight and something combustible to the door, and the adhesive may not be covered by the door's evidence. They also tend to end up near the edges where they can interfere with closing. A wall hook nearby is the safer choice.
Do over-door hooks damage fire doors?
They often do. The hook sits in the gap at the top of the door, where it can crush or wear away the intumescent strip and smoke seal, scrape the finish and stop the door latching. Check the head of any door where one has been used.
What should not be used on a fire door?
Anything the door's evidence does not cover: unapproved hooks and hangers, wedges and door stops that hold it open, extra locks or bolts, and paint over the seals. Each one can stop the door closing, latching or sealing properly.
Is a coat on a fire door a fire risk?
It can be. Coats and bags are combustible, and on a door in a corridor or stair they sit in the escape route. Heavy coats can also stop the door closing fully, which matters more than the coat itself.
Can you fill screw holes in a fire door?
Usually, yes, but the repair must follow a method and materials the door's evidence allows. Small screw holes are a routine repair; larger or deeper holes may need a different approach. Record what was done so the repair can be shown at the next check.
Who can repair a fire door after hooks are removed?
A competent person working to the door's evidence and the manufacturer's instructions, who records the work. Many FMs use a third-party certified contractor. Protest ES Ltd holds BM TRADA Q-Mark certification for fire door installation, maintenance and inspection.
