RICS Property Valuations Explained: When Do You Need One & What Does It Cost?

The term "property valuation" gets used in all sorts of contexts — estate agents do them for free, mortgage lenders commission them as part of the lending process, and RICS surveyors produce them for a whole range of formal purposes. But not all property valuations are the same. In this guide, I want to explain the difference, clarify when you actually need a formal RICS valuation, and help you understand what the process involves.

Types of Property Valuation

The Estate Agent's Market Appraisal

When an estate agent comes to your home and tells you it is worth £450,000, they are giving you a market appraisal — a professional opinion of what they think the property might sell for on the open market. It is free, it is useful as a starting point, but it carries no professional regulatory standing. It is not insured, it is not regulated, and it is not accepted by HMRC, mortgage lenders or courts.

The Mortgage Lender's Valuation

When you apply for a mortgage, your lender will commission a valuation to confirm that the property provides adequate security for the loan. This is carried out on behalf of the lender — not you. It is typically a brief inspection (sometimes a desktop exercise), and it is not designed to protect your interests. Do not rely on it as a substitute for a proper survey.

The RICS Red Book Valuation

A RICS valuation — formally known as a Red Book valuation because it follows the RICS Valuation – Global Standards (the "Red Book") — is a formal, regulated assessment produced by a RICS Registered Valuer. It carries professional indemnity insurance backing, follows a defined methodology and is legally defensible. It is accepted by HMRC, courts, the Help to Buy agent and mortgage lenders.

When Do You Actually Need a RICS Valuation?

A Note on Help to Buy Valuations

Help to Buy valuations deserve special mention because they come up so frequently in our work. The Help to Buy equity loan scheme allowed buyers to purchase with a 5% deposit and a government equity loan of up to 20% (40% in London). To repay the loan or buy additional equity, you need a RICS valuation from a registered valuer.

The key points to know: the valuation must be no more than three months old at the time you submit your application to the Help to Buy agent; it must be carried out by a RICS Registered Valuer; and you must use a Target HCA approved surveyor. At Crowborough Surveyor, our RICS Registered Valuers are approved for Help to Buy valuations across East Sussex and Kent.

How a RICS Valuation Works

Our valuer will carry out an inspection of the property — typically an hour to two hours for a standard residential property — taking note of the size, condition, specification, location and any factors that might affect value (nearby noise sources, planning constraints, flood risk, etc.). They will then research recent comparable sales in the area and apply their professional judgment to arrive at a figure.

The resulting report is a formal document that includes the property details, the basis of valuation, the market evidence used, and the valuer's opinion of market value. It is signed and dated by the RICS Registered Valuer and includes a statement of compliance with the RICS Red Book standards.

How Much Does a RICS Valuation Cost?

RICS valuations for standard residential properties in the Crowborough area typically start from around £250–£400 for a Help to Buy valuation and £300–£500 for probate or matrimonial purposes. Commercial and more complex valuations are priced individually. We provide fixed-fee quotes — contact us for a personalised price.
