At Acton Surveyors, we provide formal RICS Red Book valuations for a wide range of purposes — from Help to Buy redemptions to capital gains tax, probate, and lease extensions. Here's what you need to know.
An RICS Red Book valuation is a formal, legally recognised assessment of a property's market value.
What Is an RICS Red Book Valuation?
An RICS Red Book valuation (formally known as a Regulated Purpose Valuation) is a formal, independent assessment of a property's market value carried out by a qualified RICS member in accordance with the RICS Valuation — Global Standards (the "Red Book"). It is:
- Prepared by a qualified Registered Valuer
- Compliant with international valuation standards
- Legally defensible and relied upon by courts, HMRC, and mortgage lenders
- Independent — the valuer has no financial interest in the transaction outcome

When Do You Need an RICS Valuation?
You will need a formal RICS valuation for the following purposes:
1. Help to Buy Equity Loan Redemption
If you purchased a property through the Help to Buy scheme, you need an RICS valuation when you want to repay or staircase your equity loan. The government's agent (currently Homes England) requires a formal RICS Red Book valuation to calculate how much you owe.
2. Shared Ownership Staircasing
Buying additional shares in a shared ownership property (staircasing) requires a formal RICS valuation to establish the current value of the property and the price per share.
3. Probate Valuations
When someone dies owning property, an RICS valuation is required for the Inheritance Tax return (IHT400) submitted to HMRC. The valuation must reflect the open market value at the date of death. Incorrectly valued probate assets can result in penalties from HMRC.
4. Capital Gains Tax (CGT)
If you are selling a property that was once your main residence but has since been let, or selling an investment property, an RICS valuation at the date of any relevant change of use may be required to calculate your capital gain correctly.
5. Matrimonial/Divorce Proceedings
Courts require independently assessed property valuations during financial proceedings in divorce. An RICS Red Book valuation provides the necessary independent evidence base for settlement negotiations or court proceedings.
6. Lease Extension Premium Calculation
The calculation of a statutory lease extension premium requires the current freehold and leasehold values. Both the leaseholder's surveyor and the freeholder's surveyor will prepare formal RICS valuations as part of the process. See our Lease Extension Guide for more detail.
7. Tax Planning and HMRC Disputes
RICS valuations are used to support Inheritance Tax planning (charitable remainder trusts, business property relief claims), SDLT (Stamp Duty Land Tax) disputes, and various HMRC compliance matters.
8. Remortgage or Secured Lending
Some private banks and specialist lenders require an independent RICS valuation as part of their underwriting process, particularly for non-standard properties, high-value properties, or cases where the lender's panel valuer has down-valued.

The RICS Valuation Process
A typical RICS valuation follows these steps:
- Instruction: You provide details of the property and the purpose of the valuation
- Inspection: Your RICS Registered Valuer visits the property, typically for 30–60 minutes
- Research: The valuer analyses comparable sales evidence from the local market
- Report preparation: A formal written report is prepared, signed, and dated
- Delivery: The report is delivered, typically within 5–10 working days
Frequently Asked Questions — RICS Valuations
Can I use a mortgage lender's valuation for Help to Buy redemption?
No. Homes England requires an independent RICS valuation from a Registered Valuer. The lender's valuation is for the lender's purposes only and does not satisfy the Help to Buy requirements.
How long is an RICS valuation valid for?
RICS valuations reflect the market value at a specific date (typically the date of inspection). For most purposes, a valuation is considered current for 3–6 months. After that, you may need an updated report — this is usually quicker and cheaper than a fresh valuation.
Will an RICS valuation differ from what I paid for the property?
It can, yes. An RICS valuation reflects open market value based on comparable evidence. If the market has moved since your purchase, or if there are physical factors affecting value (condition, lease length, etc.), the valuation may differ from the sale price.
What is a "desktop valuation" and is it RICS compliant?
A desktop valuation is prepared without a physical inspection. RICS does allow desktop valuations for certain purposes, but they carry more risk of inaccuracy and many clients (HMRC, courts, lenders) require a full physical inspection valuation. Always check what is required before commissioning a desktop report.
Can I challenge an RICS valuation if I think it's too low?
Yes. RICS members are required to have a complaints procedure. If you believe a valuation is significantly below market value, you can request that the valuer reconsider in light of comparable evidence you provide. In certain contexts (mortgage down-valuation disputes), your solicitor can also write to the lender's valuer.
