A RICS valuation is a formal, written assessment of a property’s market value, produced by a RICS Registered Valuer working to the RICS Valuation Global Standards (the “Red Book”). It’s independent, regulated and legally defensible, which is why it’s required for purposes such as probate, matrimonial settlements, Help to Buy redemptions, Shared Ownership staircasing, tax planning and disputes. Unlike an estate agent appraisal, a RICS valuation can be relied upon by courts, HMRC, lenders and Homes England.
A RICS valuation tells you what a property is worth, not what condition it’s in. If you need a report on condition, you need a home survey instead.

When you need a RICS valuation
There are seven common scenarios where a RICS valuation is required or strongly advised.
1. Probate
When valuing an estate for inheritance tax purposes, HMRC requires a defensible market value figure as at the date of death. An estate agent estimate is not sufficient where the estate may attract IHT or where multiple beneficiaries need an independent figure.
2. Matrimonial and divorce
A formal valuation is required during financial settlement to ensure the matrimonial home is divided fairly. Courts require RICS valuations because they are independent and produced to a recognised standard.
3. Help to Buy redemption or staircasing
If you bought through Help to Buy and want to sell, remortgage or pay back the equity loan, Homes England (via Target HCA) requires a RICS valuation that complies with their specific requirements. See our guide on Help to Buy valuations for the detail.
4. Shared Ownership staircasing
When increasing your share in a Shared Ownership property, the housing association requires a RICS valuation to determine the cost of the additional share.
5. Tax and capital gains
For capital gains calculations, asset transfers between spouses, or trust property valuations, HMRC accepts RICS valuations as the defensible market figure.
6. Disputes
In boundary disputes, partnership dissolutions or commercial disagreements, an independent RICS valuation provides an authoritative figure that both parties can rely on.
7. Internal accounting and pension purposes
For SIPP property holdings and certain accounting purposes, a formal RICS valuation is required at regular intervals.
How a RICS valuation differs from an estate agent appraisal
This is the most common source of confusion. They are entirely different products.
| Feature | RICS Valuation | Estate Agent Appraisal |
| Purpose | Independent market value | Marketing price guidance |
| Regulated | Yes (RICS) | No |
| Written report | Yes, formal | No, usually verbal or brief letter |
| Independent | Yes | No (agent wants to win the listing) |
| Legally defensible | Yes | No |
| Cost | Paid service | Free |
| Accepted by HMRC, courts, lenders | Yes | No |
An estate agent’s job is to win and sell instructions. A RICS Registered Valuer’s job is to produce an independent, defensible figure. Both are useful, but they’re not interchangeable.
How a RICS valuation is calculated
The standard methodology for residential property is the comparable evidence method. The valuer identifies recent sales of similar properties in similar locations, adjusts for differences (size, condition, position, garden, parking, etc.) and arrives at a defensible market figure.
For most valuations, three comparable transactions from the previous 6 months are required. The valuer will also consider:
- Current market conditions (rising, flat, cooling)
- Property-specific factors (lease length, layout, alterations)
- Local supply and demand
- Any visible condition issues affecting value
If the property is unusual or there are limited comparables, the valuer may use additional methods such as the investment method (for tenanted property) or the residual method (for development sites).
What’s in a RICS valuation report?
A typical report includes:
- Property description and identification
- Date of inspection and date of valuation (these can differ for retrospective valuations)
- Basis of value (most commonly “market value”)
- Comparable evidence used
- Market commentary
- Stated assumptions and any special assumptions
- The valuer’s professional opinion of value
- RICS Registered Valuer details and signature
Who carries out a RICS valuation?
A RICS valuation must be produced by a RICS Registered Valuer, which is a specific designation requiring additional registration and continuous professional development beyond standard RICS membership. Not every chartered surveyor can sign off a Red Book valuation.
Survey Hut is based in Altrincham and our RICS Registered Valuers carry out property valuations for probate, matrimonial, Help to Buy, Shared Ownership, tax and dispute purposes across the North West.
FAQs
How long is a RICS valuation valid for?
Most RICS valuations are considered valid for 3 months from the date of the report. For Help to Buy purposes specifically, the report must be valid at the point of redemption, so timing the instruction matters. After expiry, an update or new valuation is required.
Can I use a mortgage valuation instead of a RICS valuation?
No. A mortgage valuation is produced for the lender’s benefit only, is not provided to the borrower as a usable report, and does not meet the requirements of HMRC, courts, Homes England or housing associations.
Why might a RICS valuation come back lower than the asking price?
There are several reasons, including comparable evidence not supporting the asking price, market shifts since the property was listed, or property-specific issues. Our guide on down-valuations explains the most common causes.
