Most people think of property valuations purely in the context of buying a home — the mortgage lender's valuation that confirms the property is worth what you're paying for it. But there are many other situations where you might need an independent property valuation, and the mortgage valuation simply won't do.
At Balham Surveyors, we carry out RICS Red Book valuations for a wide range of purposes. Here's when you might need one — and why the quality of the valuation really matters.
What Is a RICS Red Book Valuation?
A RICS Red Book valuation is a formal, regulated property valuation carried out in accordance with the RICS Valuation — Global Standards (the "Red Book"). It provides a robust, defensible assessment of a property's market value that can be relied upon in legal, financial and tax contexts.
The key distinction from an informal "market appraisal" (which estate agents provide) is that a Red Book valuation carries professional accountability. The valuer is personally responsible for the valuation under RICS regulations, and the report can be used as evidence in legal proceedings.
Common Reasons for an Independent Valuation
1. Probate Valuations
When someone dies and leaves property as part of their estate, HMRC requires a valuation of that property for inheritance tax purposes. This must be a formal valuation at the date of death. An estate agent's opinion isn't sufficient — you need a RICS-regulated valuation.
We provide probate valuations for properties across South London, typically within 5–7 working days of instruction. Our reports are accepted by HMRC and all major probate solicitors.
2. Matrimonial and Divorce Proceedings
When a couple separates and there is a property to be divided, both parties (or their solicitors) will often require an independent valuation. In contested cases, the court may instruct a single joint expert (SJE) to provide a valuation that both parties must accept.
Our matrimonial valuations are prepared to the standard required for court proceedings and have been accepted by the Family Court in numerous cases.
3. Help to Buy Redemption
If you bought your home with a Help to Buy equity loan, you'll need a RICS valuation when you remortgage or sell the property. The Homes England scheme requires a formal RICS valuation from a RICS Registered Valuer to determine how much equity loan needs to be repaid.
This is one of our most common valuation instructions — particularly given the large number of Help to Buy properties in South London that were purchased under the scheme.
4. Shared Ownership Staircasing
Buying additional shares in a shared ownership property (known as "staircasing") requires a RICS valuation to determine the current market value and therefore the price of the additional shares.
5. Capital Gains Tax
If you're selling a property that isn't your main residence, you may be liable for capital gains tax on the increase in value during your ownership. HMRC may require a formal valuation — either of the property at the date you acquired it, or at a historical date (such as the date it stopped being your main residence).
We can provide retrospective valuations going back several years, using market data from the relevant period.
6. Leasehold Enfranchisement
If you're a leaseholder looking to extend your lease or buy the freehold of your building (leasehold enfranchisement), a RICS valuation is required to determine the premium payable. These valuations can be technically complex and need to be prepared by a valuer with experience in leasehold matters.
7. Insurance Reinstatement Value
Building insurance should be based on the reinstatement value of your property — the cost of rebuilding it from scratch — not its market value. These are often very different figures, and being underinsured can have serious consequences. We can provide formal reinstatement cost assessments for insurance purposes.
Why You Need a RICS Valuer, Not an Estate Agent
Estate agents provide "market appraisals" — informal estimates of what a property might achieve on the open market. These are useful guides, but they're not formal valuations. They're not regulated, they carry no professional liability, and they won't be accepted by HMRC, courts, or most financial institutions for formal purposes.
A RICS-registered valuer is regulated by RICS, carries professional indemnity insurance, and is personally accountable for every valuation they sign. That accountability is what makes the valuation defensible in legal and financial contexts.
The on-site inspection typically takes 30–60 minutes. The written report is usually delivered within 5–7 working days of the inspection. If your situation is time-sensitive, please let us know and we'll do our best to accommodate a faster turnaround.
Our valuations start from £350. The cost varies depending on the size and type of property, the purpose of the valuation, and how quickly the report is needed. Contact us for a specific quote.
Technically, HMRC will consider an estate agent's valuation for probate, but they are much more likely to challenge it than a formal RICS valuation. In practice, most solicitors and financial advisers recommend using a RICS valuation to avoid potential disputes with HMRC — the cost of a formal valuation is modest compared to the time and cost of an HMRC challenge.
No — they are completely different things. A survey assesses the physical condition of a property. A valuation assesses its market value. A RICS Level 2 home survey can include an optional market valuation, but this is an add-on, not the same as a standalone RICS Red Book valuation.
