Somewhere between your offer being accepted and your mortgage offer arriving, your lender values the house. For many buyers, especially first-time buyers, it feels like a milestone: someone qualified has looked at the property and the bank is happy, so the house must be fine.
That is the most common misunderstanding in the whole buying process. The mortgage valuation answers one question, and it is the lender’s question, not yours.
What the mortgage valuation is for
When you borrow to buy a home, the property is the lender’s security. If you could not repay, the lender would need to sell it to recover the loan. Before lending, it wants an independent opinion that the house is worth enough to cover that risk.
That is all the valuation sets out to establish: is this property adequate security for this loan, at this price? It is a risk check for the lender, and the report is written for the lender.
You may well pay for it, either as a fee or within your mortgage deal, but in most cases you are not the valuer’s client. You may never meet them or speak to them.
Who does it, and how
The lender instructs the valuer, usually a chartered surveyor working for a firm on the lender’s approved panel. That is why people search for a “mortgage valuation surveyor”: the person who values the house is often a surveyor, but on this job they are working for the bank.
How much looking actually happens varies:
- A physical inspection. The valuer visits, typically for a short time, and looks at the property as a whole: its type, size, general condition and location.
- An external or “drive-by” check. For some loans, the valuer only views the outside.
- An automated valuation. For many lower-risk loans, particularly where the deposit is large, lenders rely on models built from sales data. Nobody visits at all.
Whichever route is used, the figure rests largely on comparable evidence: what similar homes nearby have actually sold for recently. You can see the kind of evidence a valuer weighs on our house-price pages, which show sold prices by town and type of home from the HM Land Registry record.
What the valuation does not do
This is where buyers get caught out.
- It is not a survey. It does not set out to examine the condition of the house in detail. A valuer will not lift floor coverings, test services or investigate the roof space as a surveyor would.
- It does not tell you what work is needed. It may note things that affect value or saleability, sometimes with a phrase like “further investigation recommended”, without explaining how serious they are.
- It does not judge whether it is a good buy for you. Whether the house suits your plans, budget and appetite for work is outside its scope entirely.
A clean valuation means the lender is comfortable lending. It does not mean the house has no problems. A house can value perfectly well and still need a new roof.
Read your valuation and not sure what it is telling you? Jon can put it in context before you decide anything.
Tell Jon about your situationThe valuation and the survey: two different questions
| Mortgage valuation | Survey | |
|---|---|---|
| Who it is for | The lender | You |
| The question it answers | Is the house good security for the loan? | What condition is the house in, and what might it cost me? |
| Who instructs it | The lender | You, or your adviser |
| Depth | Usually brief, sometimes desk-based | From a condition report to a detailed building survey |
Surveys in England come at different levels, from a basic condition report to a full building survey for older or altered homes. Which level makes sense depends on the age, construction and condition of the property, and on how much risk you are taking on.
When the figure surprises you
Most valuations simply confirm the agreed price. When they do not, the effect is immediate. The lender lends against the lower of the price and the valuation, so a lower figure can leave a gap.
If you agreed £500,000 and the house is valued at £475,000, a lender offering 90% would lend £427,500 instead of £450,000. That leaves £22,500 to find, renegotiate or resolve.
A low valuation does not automatically mean you overpaid, and a matching one does not mean you got a bargain. Valuers are cautious by design, and in a fast or unusual market the evidence they rely on can lag behind what buyers are paying. We cover what to do next in our guide to down-valuations.
The valuation can also come back with a retention, where the lender holds back part of the loan until specific work is done. That turns a figure on a page into a cash-flow problem, because you usually have to pay for the work before the money is released.
Why this matters more than it seems
Buyers tend to give the valuation more weight than it deserves in one direction and less in the other. They take a satisfactory valuation as reassurance about condition, which it is not. And they take a low one as a verdict on the house, when it is often a comment on the evidence available.
Reading it correctly, alongside the survey and what you know about the seller and the chain, is what turns a confusing document into a clear decision.
Valuation in, survey pending, and the clock ticking? Forty-five minutes with Jon can save a purchase, or stop you making an expensive one.
Tell Jon about your situationWhere an independent view helps
Jon has spent his career around these reports, on the agency side, alongside valuers and surveyors, and with buyers trying to make sense of them. A consultation is a chance to talk through what your valuation and survey actually say, what matters and what does not, and what your sensible options are, with someone who has no stake in whether the sale goes ahead.
