When it comes to understanding what your property is worth, there are two very different types of assessment available — and confusing them could cost you significantly. This guide explains the key differences between a RICS formal valuation and an estate agent’s appraisal.
The Estate Agent’s Appraisal
An estate agent’s market appraisal is a free, informal estimate of what your property might achieve if marketed for sale. The agent will visit the property, assess its condition and location, compare it with recent local sales, and give you a figure — or often a range of figures depending on market conditions.
This appraisal has no professional liability attached to it. The agent is not regulated in the same way as a RICS surveyor, and their valuation cannot be used for legal, financial or tax purposes. It is also, by its nature, an opinion influenced by the agent’s desire to win your instruction.
The RICS Formal Valuation
A RICS Red Book valuation is a formal, regulated assessment of market value carried out by a RICS Registered Valuer. It is a written document that contains a specific opinion of value, supporting evidence (comparable transactions, market commentary), and is prepared under RICS Professional Standards. The valuer carries personal professional liability for the opinion expressed.
A RICS valuation is legally accepted by HMRC, courts, mortgage lenders, and all other bodies requiring a formal opinion of value.
When You Need a RICS Valuation
You need a formal RICS valuation — not an estate agent appraisal — for: Help to Buy equity loan redemption; probate and inheritance tax calculations; matrimonial proceedings and divorce settlements; shared ownership staircasing; lease extension premium calculations; capital gains tax calculations; pension fund property assets; and mortgage lending (your lender will commission their own, but you may need an independent one).
How Much Does a RICS Valuation Cost?
Formal RICS valuations for residential properties typically cost £200–£500 depending on size, complexity and purpose. Always instruct a RICS Registered Valuer — this is a specific designation separate from general RICS membership. You can verify Registered Valuer status at rics.org.
