A property valuation report is a formal, evidenced statement of a property's value prepared by an RICS Registered Valuer to the RICS Valuation – Global Standards — the “Red Book”. Unlike an estate agent's free appraisal, a valuation report has a defined basis of value, documented comparable evidence and professional liability behind the figure — which is why HMRC, courts, lenders and housing associations rely on it.
The “Red Book” is the profession's shorthand for the RICS Valuation – Global Standards — the mandatory rulebook every RICS Registered Valuer works to. It governs how the valuer must inspect, what evidence must be recorded, which basis of value applies, what the report must contain and how the valuer's independence is safeguarded. When a solicitor, HMRC, a lender or a housing association asks for a “Red Book valuation”, this is what they mean: a regulated valuation report signed by a Registered Valuer, not an informal appraisal. Every valuation report arranged through Survey Merchant is prepared on this basis — for a deeper explanation, read our Red Book valuation guide.
Market Value — the price the property would reasonably achieve between a willing buyer and a willing seller at the valuation date — is the basis behind most valuation reports of property, from probate to Help to Buy. Other instructions call for a different basis: Market Rent for lettings and rent reviews, Fair Value for company accounts under FRS 102, and reinstatement (rebuild) cost — which is not a market figure at all — for buildings insurance. Part of the valuer's job is confirming the correct basis for the purpose before any figure is produced, because a report on the wrong basis will be rejected by the body that asked for it.
In divorce and separation the family home is usually the largest asset on the table, and both parties need a figure they can trust. A matrimonial valuation is a Red Book Market Value report prepared for negotiation or for the Family Court — and where proceedings require it, a Registered Valuer on the panel can be appointed as a Single Joint Expert acting for both parties, with the impartiality that role demands. If a valuation produced in proceedings is contested, the panel's valuation expert witnesses deal with exactly that.
Repaying a Help to Buy equity loan, or staircasing in a shared ownership property, requires a valuation that meets the scheme administrator's rules: an independent RICS valuer, documented comparable evidence, and a report that is typically valid for three months. A Help to Buy valuation from a Registered Valuer on the panel satisfies those requirements — and because the loan repayment is calculated from the valuation, we can arrange the inspection quickly when a redemption deadline is close.
The panel's Registered Valuers also prepare commercial property valuations — offices, retail, industrial units, mixed-use buildings and commercial land — for acquisition and disposal, secured lending, SDLT and capital gains calculations, company accounts and lease events. A commercial building valuation draws on different methods from a house valuation: comparable evidence where it exists, the investment method for tenanted property, and the residual method for land with development potential. Commercial property valuation costs depend on size, use class and complexity, so they are quoted individually — always fixed before you instruct. Buying the building as well as valuing it? Pair the report with a commercial building survey so the price you pay reflects the repairs you would inherit.
A residential valuation report typically costs £250–£500 in 2026 and is delivered within 3–5 working days of inspection. Commercial and court valuations are quoted individually. Every fee is fixed and confirmed before you instruct, so there are no surprises at report stage.
Valuations get challenged: HMRC's District Valuer queries a probate figure, an ex-spouse's advisers contest a matrimonial report, a lender alleges a valuation was negligent. When that happens the evidence needs to stand up in front of a tribunal or court — which is where the panel's valuation expert witness surveyors come in, preparing CPR Part 35-compliant reports and giving evidence where required. Instructing a Red Book valuation from the start is the best protection; expert witness support is there if the dispute comes anyway.

It may be necessary for an RICS-registered valuer to carry out a “Red Book” property valuation for the following reasons:
Institutional lenders, HMRC, accountants or solicitors may require Red Book valuations, which our panel of surveyors can provide in a bid to ensure you adhere to correct procedures and withstand scrutiny in various official and legal contexts.
Your surveyor determines the market value of your property on your behalf (or your lender’s).
The valuation report describes the price of your house or flat. This can help you determine whether the sale price is accurate or if you should renegotiate.
Sometimes, a desktop valuation can be done for new build properties that are unfinished and this will be based on photos, drawings and specifications.
A valuer will visit your property in person and, after the physical inspection of the site, they will research similar properties in the area to obtain “comparables”.
For commercial properties, desktop valuations may be performed periodically after the initial site visit and which can be more cost-effective, provided there is not structural change.
Data is gathered from the property and the local area such as its condition and measurements.
Sale prices of similar properties are researched and any planning restrictions, land zoning or upcoming projects are investigated in order to establish an accurate property value.
Yes. A valuation is not the same as a building survey. The latter focuses on assessing the structural build and condition of the property, which might affect the value accordingly. It is therefore advisable to commission both.
This is issued by RICS as a set of standards for conducting valuations. It required that surveyors provide clear information about their methodology, assumptions and sources of data in ascertaining property value. It is a protocol in determining values and which complies with legal and regulatory requirements, particularly those relating to accounting and tax.
The most recent global edition of the RICS Valuation Global Standards, often referred to as RICS “Red Book Global Standards”, contains updates from the International Valuation Standards (IVS) 2017 and aligns with advancements in ethics and measurement at an international standard.
You should ordinarily do this before the lender approves the mortgage application. In this way, you can prove to the bank that the amount you intend to borrow matches the property value, which is particularly relevant if the bank has outstanding debts to recover. The bank needs to ensure that the collateral is sufficient in relation to the amount they are lending to you. Other scenarios requiring a valuation include probate or divorce proceedings, for example.
No. Estate agents will provide you with their own estimates of how much your property can go for and these figures may be inflated to win business from you, because their interest is in earning commission.
Even though there are reputable agents who do provide good local information and what they believe to be a true figure in respect of how much they think they can sell your home for, they will not have conducted the same level of research as an RICS-Registered Valuer who collects and analyses the relevant evidence.
A property may need to be valued if a family member or friend has passed away in order to calculate the Inheritance Tax Liability (IHT) associated with the estate. The valuation must be in line with RICS Valuation Professional Standards (Red Book) to be deemed as a true market value and withstand the District Valuer’s scrutiny.
If spouses separate, then assets such as the family home and any other property will need to be valued before they get fairly/lawfully apportioned.
A chartered surveyor may be instructed as a Single Joint Expert, meaning that they are appointed to represent both parties. The valuer will be acting as an expert witness under part 35 of the Civil Procedure Rules and will therefore need to abide by the RICS Valuation Professional Standards (Red Book).
A property may have been purchased under a government loan scheme and so the valuation will be required if the owner intends to buy more shares of the same (known as “staircasing”) or sell the property. Therefore, an RICS valuer will be instructed in line with the requirements of the Housing Association or other scheme provider.
Every leaseholder of Shared Ownership properties possesses the right to purchase additional shares in their residence, known as “staircasing”. The value of shares will reflect the valuation of the property. So, if you own 50% of a £500,000 property and you wish to buy the remaining shares, then the price will come to £250,000.
You may require funding to purchase shares. Instruct a solicitor of your own to act in your interests, rather than using the mortgage lender’s. Then, have your solicitor send the instruction form and a copy of your lease to the housing association, the latter of which can be obtained from the Land Registry. The valuation tends to remain valid for 3 months, so you will need to act promptly after the survey.
Help to Buy was a shared equity scheme introduced by the government and interest free for 5 years. Buyers were allowed to obtain a government loan of 40% of the property’s value and a mortgage of 55%. A 5% deposit was all that was required from you.
On selling the property, the government receives 40% of the equity. So, if you bought a property for £500,000 and sold it for £600,000, then the government receives, £40,000 and you receive £60,000.
The last Help to Buy scheme has since ended in 2023, however. You may still need an equity valuation, though. Help to Buy redemption was introduced for buyers to pay back the loan without needing to sell their property and the valuation report would need to be supplied to the Homes and Communities Agency (HCA): Manage your Help to Buy equity loan (GOV.UK)
Selling on the open market will attract a host of possible buyers if the price is within their budget. Therefore, you will want to find out exactly what you should put your property on the market for.
Trusting a surveyor’s valuations is preferred over simply using the estate agent’s figures. An agent may purposefully convince you that the property is worth more in order to win the instruction for commission reasons. As a result, you do not want the property being marketed at too high a price and then going “stale”, after which period you will be pressured to reduce the sale price anyway.
The Right to Buy scheme allows you as a tenant to purchase your council or housing association residence at a discounted price. You should verify your landlord’s valuation by instructing your own independent valuation, which will help you establish the true value of your home under Right to Buy.
The Annual Tax on Enveloped Dwellings (ATED) is annual tax that mainly affects businesses which own properties in the UK worth over £500,000. You should endeavour to get a valuation and pay the correct amount promptly to avoid hefty fines or you can challenge valuations with the District Valuer if necessary. Properties excluded from this tax category are guest houses, hotels, school/student/military housing, hospitals, prisons and care facilities.
What you need to pay is described here: Annual Tax on Enveloped Dwellings: what you need to pay (GOV.UK)
This relates to the sale of your UK property whilst residing outside the UK and navigating the associated tax requirements.
You will need to pay tax on any income derived from the UK, even if you do not live there. A non-domicile tax valuation provides essential information to you and your legal advisors by outlining what you are required to pay.
This may be needed if you purchased a property before 1982 in order to calculate Capital Gains Tax (CGT). So, the valuer needs to determine the value of the property when it was bought in comparison to present market value.
A residential RICS valuation report typically costs £250–£500 in 2026, depending on property value, location and complexity. Commercial and court valuations are quoted individually — always fixed before instruction.
The inspection itself takes 30–60 minutes; the signed report is delivered within 3–5 working days. Most valuations are relied on for three months before a review or re-issue is needed.
An estate agent appraisal is a free marketing estimate with no defined basis of value and no liability. An independent RICS valuation is a regulated, evidenced report that HMRC, courts, lenders and housing associations will actually accept.
