Tell us about the building and why you need it valued, and we'll match you with RICS Registered Valuers who know your sector and area. Compare no-obligation quotes in about a minute, and get a Red Book report that lenders, accountants, HMRC and the courts will accept.
You need a formal valuation whenever someone other than you has to rely on the figure: a lender deciding how much to advance, an accountant putting the building on a balance sheet, HMRC assessing tax, a court, or the other side of a deal. For that, the valuation has to be a written report by an RICS Registered Valuer under the RICS Red Book, stating the basis of value, the valuation date and the assumptions made. An agent's appraisal or an online estimate will not do the job.
Maintained by the ComSurv team and checked against UK government, HSE and professional-body sources. ComSurv is a matching service, not a firm of surveyors or contractors. General information, not professional advice.
A reasoned, written opinion of value from an RICS Registered Valuer, prepared to a published professional standard. It records what was valued, on what basis, at what date and on what evidence, so that a third party can rely on it.
Market Value, Market Rent, Fair Value or Investment Value, stated in the report.
Comparable sales and lettings, yields and the tenancy position are analysed and recorded.
The valuer must check for conflicts of interest and carries professional indemnity insurance.
Multi-let, investment and specialist buildings are valued on their income, lease terms and risk.
Answer a few quick questions about the property, what you need and your timeline.
We shortlist RICS Registered Valuers who cover your area and property type.

The valuer agrees written terms of engagement with you, including the purpose and basis of value. They inspect and measure the property, review the title, leases, tenancy schedule and planning position, and analyse market evidence. Investment property is valued on its income and yield; owner-occupied buildings by comparison; trading and specialist property by the method that suits it. You receive a signed report setting out the value and how it was reached.
A valuation is only as good as who can rely on it.
A figure from an agent or a website is useful for a conversation and worthless to a bank, an auditor or HMRC. A Red Book report from an RICS Registered Valuer with experience in your sector and size of building is what stands up. On larger assets, where a small shift in yield moves the value by hundreds of thousands, that experience is the whole point.
