Choosing a survey
What is the difference between a mortgage valuation and a home survey?
A mortgage valuation is for the lender, to decide whether the property is security for the loan. It is not a condition survey bought for you. An RICS Home Survey describes condition for the buyer. You can have a valuation and still know little about the roof, the wiring or the drains. Read which document you were given.

Why are there two different documents?
The lender wants to know that the property is adequate security for the money. Their valuation answers that question, often from a limited look and from comparables. You want to know what you are taking on: the roof, the damp, the services, the alterations. An RICS Home Survey answers that, at the level you choose. Paying a valuation fee in a mortgage illustration does not buy the second document.
RICS is clear that a Home Survey is the buyer’s product, in three levels. A Level 2 can be instructed with a market valuation if you want a value as well as a condition report. That valuation is yours, under that instruction. It is not the same piece of paper the lender may have commissioned for themselves, and you may not be entitled to rely on theirs.
What might the lender’s valuation still mention?
A valuer who sees an obvious, serious defect may report it to the lender, because it affects the security. You might then hear about a retention, a down-valuation, or a request for a specialist report. That is a fragment, not a survey. It will not walk the house element by element, and it will not give you the maintenance advice a Level 2 or Level 3 exists to give.
- A retention is the lender holding back money. It is not a quote.
- A down-valuation is their view of value. It is not a defect list.
- A request for a timber, damp or roof report means they want someone else to look. It does not specify the repair.
Do you need a survey if the valuation came back fine?
Yes, if you want to know the condition before you are committed. “Fine” means the lender is willing to lend on the terms they offered. It does not mean the gutters are sound or the electrics were tested. Many buyers only discover the difference when the Level 2 arrives after they have already stopped worrying. Instruct the survey while you can still use it.
How do you tell which document you have?
Look at who it is addressed to and what it says it is. A mortgage valuation is addressed to the lender’s purpose. An RICS Home Survey names Level 1, 2 or 3 and explains the condition ratings. If the only thing in your inbox is a one-page figure from the broker, you have not had a survey. Ask, before exchange, while the answer can still change what you do.
Nothing on this page is mortgage advice or a valuation. We do not say what a lender will do.
Common questions
The lender’s fee was on my illustration. Have I paid for a survey?
You have paid for whatever that illustration describes, which is usually the lender’s valuation. Read the wording. If it does not say RICS Home Survey Level 2 or Level 3, you have not bought one. The two fees can both be due.
The valuation was free. Does that change what it is?
No. A fee of zero does not turn a lender’s valuation into a condition survey. It still answers the lender’s question. You still need your own Level 1, 2 or 3 if you want condition advice.
The lender wants a retention. Does that mean the house is falling down?
It means they are not prepared to advance the full loan until something is resolved. It might be a specific, limited repair, or it might be that they want a specialist report. Ask for the wording. Then read your own survey, if you have one, before you treat the retention figure as the cost of the job.
Can a home survey change the lender’s value?
The survey is not addressed to the lender unless you and they have agreed that. A condition report you commission does not, by itself, reset their valuation. If you want them to see it, that is a conversation with the broker, and it is still not advice from this page about whether they should.
If I buy a Level 2 with a valuation, can the lender use it?
Only if they agree to. Many lenders insist on their own valuation from their own panel. A Level 2 valuation is useful to you. Do not assume it replaces their instruction. Ask the lender before you pay for a valuation you do not need.
If you are buying without a mortgage, do you still need a survey?
You do not have a lender forcing a valuation, which means nobody else is even glancing at the building. A cash purchase is a reason to choose a level carefully, not a reason to skip it. The building does not know how you are paying.
Does a new-build warranty replace both?
A warranty is a contract with conditions and exclusions. It is not a Level 2 and it is not the lender’s valuation. Snagging and warranty inspections have their own scope. Read what was inspected. Do not treat a warranty as a survey you forgot to book.
When should the survey happen relative to the valuation?
Early enough that you can renegotiate or withdraw before you are committed. Waiting until after the lender is “happy” feels efficient and leaves you reading a Level 3 in a hurry. The valuation and the survey answer different questions and can be in progress together.

Key facts
- Who it is for
- The valuation is for the lender’s decision. The Home Survey is for you, the buyer, at the level you instruct.
- What a valuation is not
- A list of repairs, a roof inspection to Level 2 or 3 standard, or advice on whether to proceed.
- Level 2 valuation
- You can buy an RICS Level 2 that includes a market valuation. That is still a Level 2 survey plus a value, not the lender’s short report.
- Retention
- A lender may retain part of the loan until work is done. That is their risk decision. It is not a specification of the repair.
