Listed buildings and conservation areas
Who do you ask before you cut a new opening in a listed house?
Ask the council’s conservation officer whether listed building consent is required, and ask a structural engineer how to support the wall. The home survey does not design the opening and does not grant consent. Historic England’s point that the whole building is listed is why an internal opening is not “only inside, so it is fine”.
Last reviewed 24 October 2026. Written for buyers in England and Wales unless this answer says otherwise. No named surveyor has signed this page. It is general guidance, not a report on your house, and not legal advice.
What is the fuller explanation?
Buyers often plan a kitchen opening after they have read a survey that never mentioned the wall. The survey’s job was condition. Your job, if you intend to alter a listed house, is consent first. Unauthorised work can be enforced. That is a legal consequence the council explains. We are not your advocate. We are telling you not to skip the question.
An engineer’s design, a joiner’s detail and the consent drawings are how a lawful opening is priced. Until those exist, a builder’s guess is not a budget. Ask the surveyor only if they saw a defect in that wall already, such as a failed lintel. That defect is separate from your wish for a wider room.
What should you ask your surveyor?
- Did you see any lintel or beam where I hope to open up?
- Would that wall’s condition change how an engineer designs an opening?
- Are you able to say consent is not needed? You should not.
What are the typical next steps?
- Put the opening on hold until the council has advised you.
- Do not let a builder form the opening in the week after completion “before anyone notices”.
- If the survey found a structural defect in the same wall, deal with that advice too. Consent and structure both apply.
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.

Does a like-for-like repair need the same consent as a new opening?
Repairs and alterations are treated differently, and the line between them is the council’s to explain. Ask them about the specific job. Do not assume every nail needs an application, and do not assume a new steel is only a repair.
Who is the conservation officer?
They work for the local council. The list entry tells you the building is listed. The council tells you how to apply.
