Survey costs
Nothing on the visit sampled a mortgage valuation, opened the front vault or tested a structural inspection the valuation is not. What has to stay undecided?
The front vault stays undecided, and so does any structural inspection, because a mortgage valuation is not that inspection. Nothing on the visit sampled the valuation as if it were a home survey, and nothing opened the front vault. MoneyHelper is clear that a mortgage valuation is not a structural survey. The visit serves the lender. It has not described the vault lining, the steps, or water held there. Those points stay open until a home survey that is instructed to look has reported. Do not merge the valuation figure with the vault.

What is the fuller explanation?
A valuation visit exists so the lender can consider the security. It is a short look for that purpose, not a room-by-room account of structure. A front vault is often a cellar-like space under the pavement, with its own stair, lining and damp path. If nobody went down, none of that was seen. Recording that the valuation happened does not invent an inspection of the vault, and it does not test joists, walls or tanking that a home survey might later describe.
Ask the solicitor to keep the lender's valuation and any home survey as two instructions. If the vault matters, instruct a survey that says it will enter it, and say so in the terms. Do not ask the lender to relabel the valuation as a structural inspection. MoneyHelper's distinction stands: the valuation is not that survey. Tell the firm what access the vault needs before they attend.
What should you ask your surveyor?
- Was the front vault entered on the valuation visit?
- Which lining, stair or damp mark in the vault is still undescribed?
- Will a separate home survey be instructed to enter the vault?
What are the typical next steps?
- Keep the valuation and any home survey as separate instructions.
- Ask a survey firm to confirm vault access before they attend.
- Tell the solicitor the valuation did not open the vault.
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 the lender's figure describe the vault lining?
No. The figure is a valuation result for the lender. It does not describe lining, steps or water. MoneyHelper is clear that a mortgage valuation is not a structural survey. The lining stays undescribed until a home survey that enters the vault has reported.
If you later instruct a home survey, does that rewrite the valuation?
No. A later home survey describes condition for you. It does not edit the lender's figure, and the lender does not have to adopt it. The two documents answer different questions. Keep the vault findings in the survey and the figure in the valuation.
