Proof that every door is fit for use
Our fire door certification in London gives you clear proof of what each fire door is and how it was fitted. Every door we install comes with a certificate, a label and a dated record.
Fire door certification explained
Fire door certification is the paperwork that proves a door is a genuine fire door. It shows the door’s rating, who made it and how it was fitted.
There are two parts. The maker certifies the door itself. The installer records that it was fitted to the test evidence, as we do on every fire door installation.
Inspectors, insurers and buyers all ask for proof. A door that looks like a fire door is not enough on its own.
Without paperwork, a door’s rating cannot be confirmed. Unknown doors often end up being replaced, even when they are sound.
Many older doors still carry a label or plug from the maker. We can look for it and trace what the door is.
If no proof can be found, our fire door specialist team will tell you honestly. We cannot certify a door we cannot identify.
Where proof lives
Most certified fire doors carry marks you can find yourself. These are the places we look first.
Many makers fix a label to the top of the door.
A coloured plug can show the maker and rating.
Fire-rated glass carries an etched mark in a corner.
Fire-rated hinges and closers carry CE or UKCA marks.
Certificates from the maker or the original installer.
Door schedules from when the building was fitted out.
How it works
For new doors, certification is built into the fitting. For existing doors, we start by tracing what is there.
We confirm the maker, rating and test evidence.
New doors are fitted to the evidence. Existing doors are checked.
Rating, location, photos and checks are written up.
You get a certificate and record for each door.
What you get
Each certificate is a short, clear record for one door. Together they form your building’s door file.
Common problems
These are the paperwork problems that bring people to us.
Decorators often paint over labels. We look for other proof.
Certificates go missing when buildings change hands.
A past replacement with no record of what was fitted.
New glass with no fire rating mark.
No proof that past repairs kept the rating.
A deadline to produce proof for a sale or policy.

What people ask about fire door certificates and proof of rating.
For new doors we fit, certificates are included. Tracing and checking an existing door usually costs £35–£75 per door, before VAT. A full building door file is around £250–£600. Larger buildings cost less per door, as we can trace and check many doors in one visit. If a door cannot be proved, we tell you before you pay for anything more.
Look for a label on the top or hinge edge, a coloured plug in the edge, or an etched mark on the glass. Paperwork from the maker or installer also counts. If you cannot find any of these, the door may still be a fire door, but you cannot prove it. A fire door inspection can find marks that are easy to miss.
You need proof that each fire door is what it claims to be. A certificate, label or maker’s paperwork is the clearest way to show it. The law does not use the word certificate, but the Responsible Person must be able to show the doors are fit for use. Without proof, inspectors and insurers may treat a door as unrated.
Only if its maker and rating can be traced and it is in good condition. If there is no proof at all, it cannot be certified and usually needs replacing. We look for labels, plugs, glass marks and old paperwork. Where we can trace the door, we check it still matches its evidence and record it with photos.
Most labels are on the top edge or the hinge edge of the door. Some makers use a coloured plug set into the edge instead. Labels are often hidden under paint or behind the closer arm, so they are easy to miss. Never remove or paint over a label, as it is often the only proof the door has.
A written record of the door, its rating, its maker and how it was fitted. It sits alongside the maker’s label on the door itself. Together, the label and the certificate prove the door is genuine and was fitted to its test evidence. A building with a certificate for every fire door is much easier to sign off.
We look for other proof, such as a plug, glass marks or paperwork. If none is found, the door usually needs a fire door replacement. A door with no proof of rating cannot be signed off, even if it looks solid. Replacing it with a certified doorset is usually quicker and cheaper than trying to prove an unknown door.
Every door we fit comes with a certificate, photos and the maker’s label. The certificate lists the door’s number, location, rating and maker, plus the checks we made after fitting. Keep it with your fire safety records, as inspectors, insurers and buyers often ask to see it.
