Survey costs
The surveyor talks you through the engineer's letter on the phone. Has that call produced the engineer's findings?
No. The call has not produced the engineer's findings. Those findings are what the engineer wrote. The surveyor is helping you read someone else's letter. A phone explanation does not make the surveyor the author of the investigation, and it does not repeat the tests or the opening-up the engineer did. Whether the call sits inside the survey firm's terms is a question for those terms. It is still not a second original of the engineer's work.
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 leave a helpful call believing the survey now contains the engineering. It does not, unless the surveyor issues something that says so, and even then they cannot conjure findings the engineer did not make. Ask the surveyor to keep the roles plain: what the letter says, what they can explain in ordinary language, and what they will not reinterpret. If you disagree with the engineer, the route is back to the engineer, not a hope that a phone call rewrites their conclusions. The home-survey guidance does not price that call as a national extra, and it does not turn it into a calculation.
If you want written comments, ask whether the firm will put anything in writing and whether that is included. A verbal chat can be misunderstood a week later in a negotiation. Do not tell the seller the surveyor has adopted the engineer's fee, the engineer's conclusions, or a repair price the letter never stated. Keep the letter as the engineer's document. Keep the survey as the survey. The call, however clear, is commentary. It is not a new investigation and not an invoice for the works the engineer discussed.
What should you ask your surveyor?
- Are you explaining the letter, or adopting it as your own finding?
- Will any comment be confirmed in writing, and is that included?
- What must I ask the engineer rather than you?
What are the typical next steps?
- Treat the letter as the engineer's findings.
- Ask what the call did and did not include.
- Do not tell the seller the phone call was a new investigation.
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
If the surveyor sounds worried, has the engineer changed their mind?
No. Tone on a call is not a revised engineering report. Only the engineer can change the engineer's findings.
Does a long call get added to the engineer's bill?
Not by the survey guidance. The engineer's bill is the engineer's. The survey firm's terms govern the survey firm's call.
