Property valuations are not one-size-fits-all. The type of valuation you need depends entirely on why you need it — buying a home, settling an estate, resolving a divorce, applying for planning permission, or satisfying a mortgage lender are all very different scenarios with very different requirements. Getting the wrong type of valuation can mean the report is refused by HMRC, rejected by a lender, or simply useless for its intended purpose.
At Hampton Surveyors, our team of RICS Registered Valuers carries out a full range of residential and mixed-use property valuations across Hampton, West London and Greater London. In this guide, we explain every common type of property valuation, what it involves, who it's for, and roughly what it costs.
What Is a Property Valuation?
A property valuation is a formal, professional assessment of a property's market value at a specific date, carried out by a qualified valuer. This is quite different from an estate agent's appraisal, which is an informal commercial estimate with no professional accountability, no regulatory framework, and no legal standing.
A formal RICS valuation is prepared under the RICS Valuation — Professional Standards (the "Red Book"), which sets out the methodology, assumptions, and disclosure requirements that all RICS Registered Valuers must follow. This means the valuation is defensible, impartial, and accepted by courts, HMRC, mortgage lenders, and other professional bodies.
Mortgage Valuation
The mortgage valuation is the most widely encountered type of property valuation. When you apply for a mortgage, your lender will commission a valuation — not to protect you, but to protect themselves. They want to know that if you default on the loan, the property is worth at least as much as they are lending you.
Mortgage valuations are typically brief — often less than 30 minutes on site — and the resulting report is minimal. You may not even see the full report; the lender often just tells you whether the property "values up" (i.e., the surveyor agrees it is worth the purchase price). A mortgage valuation is not a survey — it does not assess the condition of the property, identify defects, or advise you as a buyer.
The key lesson: never confuse a mortgage valuation with a homebuyer report or building survey. The mortgage valuation protects the lender. A RICS Homebuyer Report or Level 3 Building Survey protects you.
RICS Red Book Valuations
The term "RICS Red Book valuation" refers to any formal property valuation carried out in accordance with the RICS Valuation — Professional Standards. This is the gold standard for formal valuations. All of the specialist valuation types described below — probate, matrimonial, Help to Buy, etc. — are Red Book valuations.
Red Book valuations must be carried out by an RICS Registered Valuer (not just any RICS surveyor — registration on the RICS Valuer Registration scheme is a separate, specific qualification). At Hampton Surveyors, our registered valuers hold this specific qualification and can provide Red Book valuations for a wide range of purposes.
Help to Buy Valuation
If you purchased your home using the Help to Buy Equity Loan scheme, you will need an RICS Red Book valuation in several circumstances:
- When you want to repay part or all of the equity loan
- When you want to remortgage and include the equity loan in the new mortgage
- When you want to sell your home
- When you apply to staircase (buy out additional equity)
The government requires the valuation to be carried out by an RICS Registered Valuer and submitted within specified timescales. The valuer must assess the current open market value of the property, from which the amount to repay to Homes England is calculated (as a percentage of that current market value, not the original purchase price).
Help to Buy valuations are time-sensitive — the valuation is typically only valid for three months. At Hampton Surveyors, we can usually deliver a Help to Buy valuation report within 5–7 working days of inspection, helping you meet your lender's or Homes England's deadlines.
Probate Valuation
When someone dies and leaves property as part of their estate, a probate valuation is required to calculate the Inheritance Tax (IHT) liability. The valuation establishes the open market value of the property at the date of death — this is the figure used by HMRC to calculate whether IHT is due and, if so, how much.
HMRC takes probate valuations seriously. District Valuer Services (the HMRC specialist arm) regularly checks probate valuations and can challenge figures they believe are too low. An accurate, well-evidenced Red Book valuation from a Registered Valuer — with comparable sale evidence properly documented — is much more likely to be accepted by HMRC first time, avoiding delays and disputes.
Probate valuations must assess the value at the date of death, which may be some time in the past — requiring a retrospective valuation using evidence available at that date. Our team has extensive experience in retrospective valuations and HMRC liaison.
Matrimonial / Divorce Valuation
When a marriage or civil partnership ends, the matrimonial home must typically be valued as part of the financial settlement. In many cases, one party's solicitor and the other party's solicitor each appoint their own valuer, and the two valuations become part of the legal process.
Where both parties agree to share the cost and appoint a single valuer — known as a "Single Joint Expert" (SJE) — the process is quicker and less adversarial. Hampton Surveyors is experienced in acting as Single Joint Expert for matrimonial valuations, providing an objective, court-admissible report that both parties can rely on.
Matrimonial valuations require particular sensitivity. The property is often the family home, emotions run high, and the valuer may face pressure from both parties to value the property higher or lower to suit their preferred outcome. As an independent RICS Registered Valuer, our obligation is to the court and the evidence — not to either party.
Shared Ownership Valuation
Shared ownership schemes — where you buy a share of a property (typically 25–75%) and pay rent on the remainder — require RICS Red Book valuations for staircasing (buying additional shares), selling, or in some cases remortgaging. The valuation determines the current full market value of the property, from which the price of the additional share is calculated.
Insurance Reinstatement Valuation
This is not the same as a market valuation. A reinstatement cost assessment (RCA) establishes the cost of completely rebuilding the property from scratch if it were destroyed — for the purposes of setting the buildings insurance sum insured. This is a construction cost exercise, not a market value exercise, and requires a different methodology.
Under-insuring a property is a serious risk — in the event of a total loss, the insurance payout would be insufficient to rebuild, leaving the homeowner with a significant shortfall. We recommend all homeowners have their reinstatement value checked every three to five years, as construction costs change significantly over time.
Capital Gains Tax Valuation
If you sell a second property, a buy-to-let investment, or a property that was not your principal private residence throughout your ownership, you may be liable for Capital Gains Tax (CGT). The CGT calculation requires establishing the value of the property at the time you first owned it (or at April 1982 for very long-held assets), which may require a retrospective RICS valuation.
Rental / Investment Valuation
Landlords and investors often need formal assessments of rental value — the Market Rent (MR) at which a property would be let in the open market — for tax purposes, lease renewal negotiations, or when acquiring or disposing of investment property. Our registered valuers can provide both capital value and rental value assessments for residential and mixed-use properties.

"Oliver at Hampton Surveyors provided a probate valuation for my late mother's house in Richmond in less than a week. HMRC accepted the figure without question and the estate was settled smoothly. His report was detailed, clearly evidenced and entirely professional. I wouldn't hesitate to use Hampton Surveyors again."

Frequently Asked Questions
No. HMRC requires a formal RICS Red Book valuation from a Registered Valuer for probate purposes. An estate agent's appraisal — however experienced the agent — has no professional regulatory framework, no mandatory methodology, and is not accepted by HMRC as a formal valuation. Using an agent's figure risks an HMRC challenge, which can cause significant delays to probate and potential penalties.
A Help to Buy valuation is valid for three months from the date of the inspection. If your transaction takes longer than three months, you will need a new valuation. It is important to plan ahead and commission the valuation at the right time — not too early (or it will expire before completion) and not too late (or you will miss your lender's deadline).
Market Value (MV) is the estimated amount for which an asset should exchange on the date of valuation between a willing buyer and a willing seller in an arm's length transaction. Market Rent (MR) is the estimated amount for which an interest in real property should be leased on the date of valuation. Both have formal RICS definitions. You need market value for most capital purposes (buying, selling, CGT, probate) and market rent for tenancy-related purposes.
No — your mortgage valuation is carried out for your lender's benefit, not yours. It confirms that the lender's security is adequate. It does not identify defects, assess the condition of the property, or provide you with advice. You need a separate RICS Homebuyer Report or Level 3 Building Survey to protect your interests as a buyer. Never assume the mortgage valuation means the property is in good condition.
We understand that many valuations are time-sensitive. For Help to Buy, probate and other formal valuations, we aim to carry out the inspection within 3–5 working days of instruction and deliver the written report within a further 3–5 working days. Urgent turnarounds can often be arranged — contact us to discuss your deadline and we will do our best to accommodate it.
