What can a home survey say if a letterbox or a cat flap has been cut through the entrance door of a flat?
It can say there is a hole in the door leaf and describe the letter plate or flap it saw. It cannot say the door fails a fire test, because a visual survey does not fire-test doors and cannot tell from a hole alone what the leaf was built to do. The opening is a condition comment about that leaf, not a certificate, and not proof that other doors in the flat match it.

What is the fuller explanation?
Flat entrance doors are often more than a piece of timber or a composite skin, but the surveyor sees the face, the frame, the closer if there is one, and any hole cut for post or a pet. A letterbox or a cat flap may be factory-made or cut in later. The survey can describe a rough cut, a split panel or daylight at the flap. It cannot invent a fire result, a test reference or a pass. Those words do not belong in the condition rating unless the survey is quoting a document it actually read, which a standard inspection does not certify.
Ask the managing agent or the seller what the door is supposed to be, and ask your solicitor what the lease requires. That paperwork is not the hole. If the leaf is damaged, a joiner can describe the damage. There is no RICS price for a new entrance door, and a new door may need the landlord’s consent. The survey does not apply for consent and does not test smoke seals. If seals were painted over or missing, the survey can say they were not seen. It still has not tested the door.
What should you ask your surveyor?
- What hole or flap did you see, and was the cut tidy or broken?
- Are you limiting your comment to condition, not a fire test?
- Did you see the frame, the closer and the seals, or only the leaf?
What are the typical next steps?
- Ask the solicitor and the agent what standard the entrance door is held to.
- Do not treat the survey as a fire certificate.
- If the leaf is split around the flap, price that damage separately from any upgrade.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Is a letterbox on a house door the same?
The survey can still describe a hole. The flat entrance is where people hope the door does more than keep the weather out. The survey still does not test that hope.
Does a cat flap in a kitchen door inside the flat matter as much?
It is damage to that leaf only. Do not copy a fire comment onto an internal kitchen door the survey has not described as a fire door.
