A RICS valuation answers one specific question: what would this property sell for, on the open market, today? Nothing about its condition, nothing about defects, nothing about what's wrong with the roof. For a standard residential property in 2026, a formal Red Book valuation from an RICS Registered Valuer typically costs £250–£600, with probate and inheritance tax work running £300–£800, divorce and matrimonial valuations £350–£750, and capital gains tax valuations £300–£700. Add a valuation to a Level 2 HomeBuyer survey and the combined fee usually lands around £500–£1,100.
But it depends what you're actually asking for. "Valuation" gets used loosely to cover at least four different products — a free estate agent appraisal, a lender's mortgage valuation, a standalone RICS Red Book valuation, and a survey with a valuation bolted on — and mixing them up is where people either overpay for something they didn't need, or rely on something that was never built to be relied on.
I'll be straight about my own position on this one up front, because it matters for what follows: I diagnose condition, I don't produce Red Book valuations, and I'll explain exactly why further down.
The short answer
Figures below are cross-checked across several UK surveying-practice cost guides, current to September 2026. Treat the standard valuation range as the reliable core figure; probate, matrimonial and CGT work sits higher because of the extra evidence and liability behind a figure that HMRC, a court or an ex-spouse's solicitor might later test.
| Valuation type | Typical cost (2026) | What's included |
|---|---|---|
| Mortgage valuation (lender's own) | £150–£400 (often free) | Confirms security for the loan; for the lender, not you — often a drive-by or desktop check |
| Standard RICS Red Book valuation | £250–£600 | Registered Valuer's liability-backed opinion of market value, with comparable evidence |
| Probate / inheritance tax valuation | £300–£800 | Date-of-death market value, defensible if HMRC's District Valuer queries it |
| Valuation added to a Level 2 survey | £500–£1,100 combined | Condition assessment plus a market valuation and reinstatement figure in one visit |
London and the South East trend 10–25% above these national figures, in line with most trades in this series; unusual or high-value properties, and anywhere requiring extensive comparable research, push toward the top of every band.
What drives the price
Property value. Fees generally scale with price, not just complexity, because a Registered Valuer's professional liability exposure rises with the figure they're putting their name to. A flat worth £150,000 and a house worth £1.2m are not priced the same, even if both are perfectly ordinary properties to inspect.
Purpose. A straightforward market-value opinion for a private sale costs less than the same exercise done for probate, divorce or capital gains tax, where the valuer knows the figure may be challenged by HMRC, an ex-spouse's solicitor, or a court, and has to document the comparable evidence accordingly.
Registered Valuer status. Only an RICS member who has joined the Valuer Registration Scheme (VRS) can produce a compliant Red Book report — it's a mandatory regulatory scheme, not an optional badge, and it's why a "valuation" from someone outside it carries no comparable weight with HMRC, lenders or the courts.
Bundling with a survey. A Level 2 HomeBuyer survey can usually have a market valuation and insurance reinstatement figure added for a modest extra fee, since the surveyor is already on site measuring the property. A standalone valuation, with no condition inspection attached, doesn't benefit from that same efficiency.
Access and location. Rural, unusual or hard-to-access properties take longer to research comparable evidence for, and add to the fee in the same way they do for any survey type in this series.
Which valuation do you actually need?
Start by ruling out what you almost certainly don't need. A free estate agent appraisal is a sales pitch dressed as a number — useful for setting an asking price, worthless as evidence for HMRC, a court or a lender, because it carries no professional standard or comparable evidence behind it. An online automated valuation model is the same problem in digital form: a starting point, not something to rely on for anything that matters legally or financially.
A mortgage valuation, arranged by your lender, is the one most buyers actually pay for without choosing to. It confirms the property is adequate security for the loan, it's commissioned for the lender's benefit, and its duty of care runs to them, not you. Many lenders bundle it in free to win your business; where they charge, it's typically £150–£400, occasionally more on higher-value properties. Either way, you often can't see the full report, and it tells you nothing about the building's condition.
A standalone RICS Red Book valuation is what you actually want when you need a defensible market-value figure for a specific purpose — probate, divorce, capital gains tax, a Help to Buy staircasing redemption, or a private sale between connected parties where an estate agent's guide price won't do. It's produced by an RICS Registered Valuer under the RICS Valuation – Global Standards (the "Red Book"), with stated comparable evidence and a basis of value, and the valuer carries professional liability for the figure. This is a different product to a survey, and doesn't include one.
A survey with a valuation added — typically a Level 2 HomeBuyer Report — is worth considering if you want both condition and a market figure from a single visit, and don't specifically need a court- or HMRC-facing Red Book valuation. It's the option most home buyers actually want, even if most don't realise a plain mortgage valuation isn't giving it to them.
The probate trap: why undervaluing costs more, not less
This is the section worth reading properly if you're dealing with an estate. The nil-rate band for inheritance tax is £325,000, plus a further £175,000 residence nil-rate band where a main home passes to direct descendants — up to £500,000 tax-free for one estate, £1m for a married couple's combined estate — and both bands are frozen at these levels until April 2031 under measures confirmed at the November 2025 Autumn Budget. Property values keep moving even when the thresholds don't, which pulls more ordinary estates over the line each year.
The obvious temptation, where an estate sits near the threshold, is to lean toward a lower probate valuation to reduce or avoid the IHT bill. Two problems with that. First, HMRC's District Valuer service reviews probate valuations and can challenge one it considers too low, which delays the grant of probate and can attract penalties on top of the tax eventually due. Second, and less obviously, the valuation an executor declares at probate becomes the beneficiary's acquisition cost for capital gains tax if the property is later sold rather than lived in as a main residence. Underdeclare the value now, save a bit of inheritance tax, and you can hand the beneficiary a materially larger capital gain — and a bigger CGT bill — the day they come to sell. A properly evidenced Red Book valuation, done once at the point of death, protects both figures rather than trading one tax for another.
The practical upshot: get a professional valuation for probate even where the estate looks comfortably under the threshold, and keep the report. It's cheap insurance against a District Valuer query now and a CGT dispute with the beneficiary's own accountant later.
Who actually does this work
Here's where I'll be straight about my own position, the same way I have been on a few other topics in this series. Only an RICS member registered under the Valuer Registration Scheme can produce a compliant Red Book valuation — a mandatory scheme, not an optional badge. I'm a Member of the Residential Property Surveyors Association (MRPSA) and an ACABE Associate, not RICS, so I'm not eligible to join VRS and won't offer a standalone valuation as a product — I'd rather say that plainly than blur what I do into something it isn't.
Where this genuinely overlaps with my own work is on the survey side. If a building survey turns up something that would materially change a property's value — unrecorded structural work, a missing completion certificate, a valuation figure that looks stale — I'll flag it in plain English and point you toward a Registered Valuer for the figure itself, rather than guess at one. The same applies selling: a seller's survey reports condition and risk up front, precisely so a buyer's own valuation doesn't surface a nasty surprise mid-transaction, but it was never intended to double as one.
What I'd watch for in a quote
- Whether the surveyor is actually a Registered Valuer. Ask directly, or check the RICS Find a Surveyor register — RICS membership alone doesn't automatically mean VRS registration.
- Whether it's a valuation, a survey, or both. A quote that doesn't say clearly which one you're buying is the single most common source of the "but I thought that covered condition" complaint I hear.
- A stated basis of value and inspection date. A defensible figure needs both, especially for probate or divorce work that might be challenged months later.
- No pressure to lowball a probate figure. Anyone suggesting a valuation should be set artificially low "to help with the tax" is setting up the capital gains problem described above, not helping you.
- Professional indemnity insurance in place, the same basic check worth making of anyone whose figure a lender, HMRC or a court might later rely on.
Questions I get asked
Is a RICS valuation the same as a mortgage valuation? No. A mortgage valuation is commissioned by the lender, for the lender, and you generally can't rely on it. A standalone RICS valuation is commissioned for you, by a Registered Valuer, under the Red Book standard — a liability-backed figure you can actually use for probate, divorce, CGT or a private sale.
Does a RICS valuation tell me what's wrong with the house? No. It answers what the property would sell for, not what's physically wrong with it. For condition and defects you need a survey, a different piece of work under a different standard — though a Level 2 HomeBuyer survey can bundle a valuation in for a modest extra fee.
Can I just use an estate agent's valuation for probate? You can, but it's risky for anything near or over the inheritance tax threshold. HMRC's District Valuer can challenge a probate valuation it thinks is too low, and a free agent appraisal gives you nothing to defend it with. A Red Book valuation costs a few hundred pounds and gives the executor something defensible.
Why would I want a higher probate valuation, not a lower one? Because that figure becomes the beneficiary's acquisition cost for capital gains tax if the property's later sold rather than lived in. Undervalue it to save inheritance tax now, and you can hand the beneficiary a bigger capital gain, and a bigger CGT bill, when they sell.
If a building survey or a seller's survey turns up something that looks like it would move a property's value — unrecorded works, a stale valuation figure, a listed building where a generic online estimate was never going to be right — that's exactly the kind of thing I'll flag plainly, before pointing you toward a Registered Valuer for the actual figure.

Small print. This guide is general information, not advice on a specific property, estate or legal matter, and it doesn’t replace advice from an RICS Registered Valuer, a solicitor or an accountant. Prices were researched and correct to the best of my knowledge on 27 September 2026; costs move and vary by region, property and purpose. Always get at least three written quotes, and confirm a valuer's Registered Valuer status directly before instructing them.
