Quick Answer
An RICS valuation, often called a Red Book valuation, is an independent, written opinion of a property’s value prepared by an RICS Registered Valuer to the RICS Valuation – Global Standards. Unlike a free estate agent appraisal, which estimates a likely asking price to win an instruction, a Red Book valuation is evidence-based, impartial and backed by professional indemnity insurance, so it can be relied on by HMRC, courts, lenders and other professionals. You’ll usually need one for capital gains tax, inheritance tax and probate, matrimonial settlements, disputes, secured lending, buying or selling an unusual property, or setting a rent. The valuer inspects the property, analyses comparable evidence and produces a report, typically within a week or two of the visit.
Not All Valuations Are Equal
Ask three estate agents what your property is worth and you’ll probably get three different answers. Ask HMRC to accept one of those figures for capital gains tax, and you may get a fourth answer of their own.
That’s because “valuation” covers some very different things. A free appraisal from an estate agent is a sales opinion. A mortgage valuation is a quick check for the lender. A Red Book valuation is something else entirely: an independent, regulated opinion you can stand behind if anyone challenges it.
Think of it like the difference between a friend saying your car looks fine and an MOT certificate. Both are opinions, but only one is official, documented and accountable.
Our Chartered Surveyors and RICS Registered Valuers have prepared residential and commercial valuations across Stoke-on-Trent, Staffordshire, Cheshire and Shropshire for decades. This guide explains what a Red Book valuation is, when you need one and what happens on the day.

What Is a Red Book Valuation?
The “Red Book” is the nickname for RICS Valuation – Global Standards, the rules published by the Royal Institution of Chartered Surveyors that govern how regulated valuers carry out and report valuations. The current edition took effect on 31 January 2025. In the UK, it’s supported by a UK national supplement covering things like tax and lending valuations.
A Red Book valuation must be carried out by an RICS Registered Valuer: a qualified surveyor who is registered, monitored and regularly checked by RICS. Under the standards, the valuer must:
- Agree the terms in writing first, including the purpose and the basis of value
- Be independent, declaring and managing any conflict of interest
- Inspect the property, unless agreed otherwise
- Base the figure on evidence, not opinion alone
- Produce a written report explaining how the figure was reached
- Hold professional indemnity insurance, so the client is protected if something goes wrong
That’s why a Red Book valuation is accepted by HMRC, the courts and lenders. It’s a figure someone is accountable for.
How Does It Compare With Other Valuations?
| RICS Red Book valuation | Estate agent appraisal | Mortgage valuation | Building survey | |
| Who prepares it | RICS Registered Valuer | Estate or letting agent | Valuer instructed by the lender | Chartered surveyor |
| Purpose | An independent opinion of value for a specific purpose | To suggest an asking price and win the instruction | To confirm the property is good security for the loan | To report on the property’s condition |
| Who relies on it | You, HMRC, courts, lenders, other advisers | You, informally | The lender | You |
| Written, regulated report | Yes | Usually not | Yes, but for the lender | Yes |
| Usually costs | A fee | Often free | Included in or added to mortgage costs | A fee |
Estate agent appraisals
A free appraisal is useful for setting an asking price, and it’s worth getting a few if you’re selling. But it’s a marketing opinion, often based heavily on the agent’s own listings, and it can’t be used for tax, legal or lending purposes.
Mortgage valuations
These are carried out for the lender, to check the property is worth enough to secure the loan. If the valuer thinks it’s worth less than the agreed price, that’s called a down valuation, and the lender may lend less.
Valuations vs surveys
A valuation is not a survey. The valuer will note obvious problems, such as visible damp, roof damage or subsidence, because they affect value, but won’t carry out a detailed inspection of condition. If you want to know what’s wrong with a building, you need a survey. See our building surveys or homebuyers report.
When Do You Need an RICS Valuation?
| Situation | Why an RICS valuation helps |
| Capital gains tax | Selling or gifting a property that isn’t your main home, or needing a value at a past date, such as when you inherited it. See our capital gains tax valuations |
| Probate and inheritance tax | Executors must report the market value at the date of death to HMRC. See probate and inheritance tax |
| Divorce and separation | An agreed, independent figure for dividing property |
| Disputes and court cases | An expert witness report the court can rely on. See expert witness |
| Lending and refinancing | Lenders often need a Red Book valuation, especially for commercial or unusual property |
| Buying or selling | An objective view, especially where comparable evidence is thin or the property is unusual |
| Transfers | Moving property into a company, a pension scheme or between family members |
| Rent reviews and lease renewals | Evidence of market rent to support negotiations |
| Company accounts | Valuing property assets for financial statements |
| Shared ownership and Help to Buy | Required to staircase, redeem an equity loan or sell |
How Is Property Value Worked Out?
Homes
Residential valuations rely mainly on comparable evidence: what similar homes nearby have actually sold for. The valuer then adjusts for the differences, including:
- Age and type of construction
- Size, layout and number of bedrooms
- Condition, recent improvements and any obvious defects
- Plot size, outbuildings, garages and parking
- Location, local amenities, schools and transport links
- Tenure, such as freehold or leasehold and the length of the lease
Commercial property
Commercial valuations use a wider range of methods, because what a building is worth often depends on the income it produces:
- Investment method: for let property, the value comes from the rent, the lease terms and the strength of the tenant
- Comparable method: for vacant or owner-occupied property, based on recent sales and lettings of similar buildings
- Residual method: for development land, working back from the value of the finished scheme. See what is a development appraisal
- Profits method: for trading property such as pubs, hotels and petrol stations, where value depends on the business’s turnover and profit
Our guide on how to determine the market value of commercial property explains these methods in more depth, and what impacts commercial property value most covers the factors owners can influence.
What to Expect at a Valuation Appointment
Before the visit
The valuer will confirm the purpose of the valuation, the basis of value and the fee in writing. It helps to have ready:
- The property address and, if you know it, the floor area
- Title documents, and the lease if it’s leasehold or let
- Details of any improvements, extensions or works, with dates and costs
- Planning permissions and building regulations sign-offs
- For let property: tenancy or lease details, the rent and any service charge information
You don’t need to dress the property as you would for viewings. The valuer looks past the décor. A tidy property with clear access to every room, the loft and any outbuildings makes the inspection quicker and more thorough.
On the day
The valuer will walk through the property and around the outside, measuring, taking photographs and noting construction, condition and features. They’ll also look at the surrounding area. A typical home takes between 30 minutes and an hour and a half. Larger or commercial properties can take longer.
Use the visit to point out anything that might not be obvious, such as a new roof, rewiring or a recent extension. You can also ask questions, although the valuer won’t usually give a figure on the spot.
After the visit
The valuer researches comparable evidence and local market conditions, then writes the report. For most valuations this takes five to ten working days after the inspection, though faster turnarounds can often be arranged.
The report sets out the value, the evidence behind it, the assumptions made and the purpose it can be used for. Keep it safe, as HMRC, a court or a lender may ask to see it.
A Real-World Example
Picture a family in Newcastle-under-Lyme who inherit a small parade of shops from their father. They ask a local estate agent for a value, who suggests £600,000 as an asking price.
Two years later, they sell for £720,000 and need to report capital gains tax. The gain is worked out from the value at the date of death, not what the agent suggested to win the listing. HMRC asks how that value was reached.
With only an agent’s appraisal, they have little to show. A retrospective Red Book valuation sets the value at the date of death at £650,000, supported by rent and lease evidence from that time. That reduces the taxable gain by £50,000 compared with using the agent’s figure, and gives them a report they can defend if HMRC challenges it.
If they’d had an RICS valuation for probate at the start, they’d have had the right figure from day one.

Summary
An RICS Red Book valuation is an independent, evidence-based opinion of value from an RICS Registered Valuer, prepared to RICS Valuation – Global Standards and backed by professional indemnity insurance. That makes it very different from a free estate agent appraisal, which is a sales opinion, or a mortgage valuation, which is for the lender.

Frequently Asked Questions
What is the difference between a Red Book valuation and an estate agent valuation?
An estate agent valuation is a free market appraisal, an informal opinion of a likely asking price, usually given to win the instruction to sell. A Red Book valuation is a regulated, written report by an RICS Registered Valuer, based on evidence and backed by insurance. Only a Red Book valuation is suitable for tax, legal and most lending purposes.
How much does an RICS valuation cost?
It depends on the property, its size and complexity, and the purpose of the valuation. A straightforward residential valuation costs less than a large commercial or specialist property, or a retrospective valuation at a past date. Ask for a quote, which will be confirmed in writing before the valuation goes ahead.
How long does a property valuation take?
The inspection of a typical home takes between 30 minutes and an hour and a half, with commercial property often taking longer. The written report usually follows within five to ten working days, though faster turnarounds can often be arranged for urgent cases.
Can a valuation be done for a date in the past?
Yes. Retrospective valuations are common for capital gains tax, where you need the value when you acquired or inherited a property, and for probate. The valuer uses evidence from the relevant date to work out what the property was worth then.
Is a valuation the same as a survey?
No. A valuation tells you what a property is worth. A survey tells you what condition it’s in. A valuer will note obvious defects that affect value, but won’t carry out the detailed inspection a homebuyers report or building survey provides.
