Age and type of house

What should you ask if a wall has been removed and the beam above is boxed in?

Ask whether any beam was seen, and do not treat the plasterboard as the structure. A removed wall needs something to carry the load, often a steel or a timber that a home survey cannot see once it is boxed. The survey can see a clear opening, a dip, or a crack. It cannot confirm the beam size, the bearings or the building-regulations approval.

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?

Approved Document A is the England guidance for structural work. It is not a letter in the seller’s drawer, and the survey does not fetch that letter. Your solicitor asks for the papers. An indemnity policy, if one is offered, does not check the bearings. A dip in the ceiling along the line of the old wall is a condition comment. A perfect ceiling is not proof the steel is adequate.

Opening the box is outside the survey. Agree it with the seller if an engineer needs to see the beam before exchange. There is no RICS price for that opening or for a new steel. Do not knock the boxing off during a viewing.

What should you ask your surveyor?

  • Could you see a beam, a padstone, or only plasterboard?
  • Is the ceiling cracked or dipping along that line?
  • Which papers should the solicitor ask for?

What are the typical next steps?

  1. Do not remove the boxing yourself.
  2. Ask for the building-regulations certificate separately from the survey.
  3. If the survey says the support is unclear, get advice before you treat the room as one space you can rely on.

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 nib wall proof the steel is there?

A nib is a leftover pier. It is not a calculation. The beam, if any, is still hidden.

Does a RSJ mentioned in a brochure count?

Only if someone can point to the paper or the beam. A sales word is not an approval.
