The lender mentions a retention after its valuation. Is that retention the same document as your home survey's rating?
No. A retention the lender mentions after its valuation is not the same document as your home survey's rating. The retention is the lender's decision on the valuation it instructed. Your rating sits in the survey you instructed about condition. MoneyHelper is plain that a mortgage valuation is not a structural survey. The two papers can talk about the same house and still not be the same finding. The survey has not set the retention, and the valuation has not become your report.

What is the fuller explanation?
Lenders use a retention when they are willing to lend but want work done, or want money held back, because of what their valuer saw. That is a lending tool. It can be triggered by something your survey also noticed, or by something the valuer saw and your survey treated differently, or the other way round. You cannot line the documents up and assume the held-back point is identical to a rating. The valuation may be brief. It is not an element-by-element survey.
Ask the lender or the broker what the retention is attached to, in their words, and read that beside your survey without forcing them to match. Your solicitor can keep the lending condition separate from the condition ratings. Do not invent the sum they will hold, and do not invent a rule they did not state. The home survey did not recommend a retention. It rated condition. The valuation is the document that led the lender to mention one.
What should you ask your surveyor?
- Is the retention the lender's decision on its valuation, not your survey?
- Have you set any retention figure in the home survey?
- Which defects in your report might be different from the valuer's note?
What are the typical next steps?
- Keep the lender's retention separate from your survey's ratings.
- Ask the broker what the retention is actually attached to.
- Do not invent the amount or the lender's rule.

If both documents mention the roof, are they the same finding?
Not necessarily. Both may have noticed the roof and still have done different jobs. A valuation is not a structural survey. The retention is the lender's tool. Your rating is the survey's condition comment. Do not merge them. Same roof, two documents: do not collapse them into one.
Can you cancel the retention by arguing with the survey rating?
No. The retention sits on the lender's valuation. Changing how you read your own rating does not instruct the lender. Ask them what would satisfy their valuation. The survey has not set that test. What would clear a retention is the lender's question, not the survey's.
