Age and type of house
The inner leaf is aircrete block where a socket was cut out. Does that offcut identify the whole house construction?
No. That offcut does not identify the whole house construction. The inner leaf is aircrete block where a socket was cut out, which is one hole in one wall. Extensions, party walls and older leaves can be different materials. The outer leaf was not named by that offcut, and the ties were not seen. The survey records aircrete at the socket. It has not mapped every wall and has not inspected the cavity.

What is the fuller explanation?
Aircrete is a lightweight block often used for inner leaves in later cavity work. Finding it behind one socket tells you the leaf at that point, because the electrician’s chase exposed it. It does not travel, by logic, to the gable, the bay or a rear wing that may be brick. A single offcut is easy to over-read as a specification for the house. The ties that would sit in the cavity beside that block were not part of the cut-out and were not tested.
If a lender or a designer asks how the house is built, give them the socket note as a local fact and say the rest was not opened. A cavity-tie inspection, if needed, is a separate instruction and was not done here. Do not drill further holes to chase the block around the house on the back of this visit. The report’s identification stops at the inner leaf where the socket was cut.
What should you ask your surveyor?
- Which room and which wall contained the socket cut-out?
- What does the report say the outer leaf is, if anything?
- Does any sentence claim every wall is aircrete?
What are the typical next steps?
- Limit the aircrete note to the socket that was seen.
- Do not describe the whole house as that one block.
- Keep any tie inspection separate from this offcut.
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
Does aircrete at one socket mean the ties are stainless?
No. The block type does not identify the ties, and the ties were not seen. Aircrete where a socket was cut is an inner-leaf note at that point only. Metal in the cavity can be older or newer than the block, and this visit did not inspect it. The offcut does not identify the whole house and does not clear the ties.
Was the outer brick identified by the same cut?
Not unless the report says the cut went through both leaves, which a socket chase normally does not. The inner leaf at the socket is aircrete. The outer leaf is a different face and was not named by that offcut. The survey has not used one plug of block to specify the whole wall.
