A property valuation surveyor provides an independent, professionally qualified opinion of a property's market value. Here's when you need one, what the process involves, and how it differs from the free estate agent valuation or your lender's mortgage valuation.
The gold standard. Produced by a RICS-regulated valuer following the RICS Valuation — Global Standards. Accepted for legal, tax, and financial purposes. Cost: £150–£500. Required for: probate, divorce settlements, Help to Buy, shared ownership staircasing, auction reserve setting, and insurance reinstatement values.
Commissioned by your mortgage lender, not you. Its purpose is to confirm the property is adequate security for the loan — not to give you an accurate market value. The report belongs to the lender and is rarely shared in detail. Cost: £150–£500 (sometimes free with certain mortgage products).
Free. An estate agent's estimate of what they think the property will sell for. Not a professional or independent valuation — agents have an incentive to quote higher to win your instruction. Not accepted for legal or financial purposes.
Automated Valuation Models (AVMs) use Land Registry data and algorithms to estimate value. Used by lenders for low-LTV remortgages. Fast and cheap (or free), but not accepted for legal purposes and can be significantly inaccurate for unusual properties.
A formal RICS valuation is more than a quick visit. Here's what the process typically involves:
| Purpose | Typical Cost | Notes |
|---|---|---|
| Probate valuation | £150–£300 | Often required same week |
| Divorce / matrimonial | £200–£400 | Court-accepted format required |
| Help to Buy redemption | £200–£350 | Must be RICS Red Book compliant |
| Shared ownership staircasing | £200–£350 | Required by housing association |
| CGT / IHT / tax purposes | £200–£500 | HMRC will query estimates without formal valuation |
| Lease extension / freehold | £400–£700+ | May include 'marriage value' assessment |
Yes. Commission your own RICS Red Book valuation and present it to your lender with comparable evidence. Lenders may review a down-valuation if you can provide strong comparable sales data. However, they are not obliged to accept your surveyor's figure.
No. A RICS valuation establishes market value — it does not give a detailed structural condition report. A Level 2 or Level 3 survey inspects condition. Some Level 2 reports include a market valuation, but a standalone valuation does not include a structural survey.
There is no fixed validity period — it depends on the purpose. HMRC typically accepts probate valuations dated within 6 months of the death; mortgage lenders usually require valuations within 3–6 months of the mortgage application. In a fast-moving market, a valuation may be considered stale more quickly.
Market value is the price a willing buyer would pay a willing seller in an arm's-length transaction, based on current market evidence. Asking price is what the seller or agent hopes to achieve — it may be higher or lower than market value depending on strategy and market conditions.
