What Is a House Valuation and What Does It Actually Involve?

Property Valuations • Buyer Guide • RICS Valuer

A house valuation and a property survey are not the same thing — but they’re often confused.
If you’ve been asked to arrange one, or you’re wondering whether you need one, this guide explains exactly what a house valuation is, what it covers, and when it applies.

Valuations serve specific purposes: for lenders, for legal matters, for probate, or for private decisions.
Understanding which type applies to your situation — and what the process involves — helps you make a more informed choice.

What Is a House Valuation?

A house valuation is a formal, professional opinion of what a property is worth in the current market. It is produced by a RICS Registered Valuer and takes into account a range of factors including location, condition, local comparable sales, and the property’s individual features.

The result is a written report that states the valuer’s professional view of the property’s open market value on a specific date. That date matters — valuations reflect market conditions at the time they are carried out.

What a valuation is not

It’s common for buyers and sellers to conflate valuations with surveys. They serve different purposes:

• A valuation tells you what a property is worth
• A survey tells you what condition the property is in
• A mortgage valuation confirms to a lender that the property is adequate security for the loan — it is not a buyer’s report

If you want to understand defects, structural issues, or repair requirements, a Level 2 Homebuyer Report or Level 3 Building Survey is the appropriate service — not a valuation.

What Happens During a House Valuation?

Step 1: The instruction and briefing

You contact a RICS Registered Valuer and explain what the valuation is for. The purpose affects both the approach and the type of report produced. Common purposes include:

• Mortgage valuation: Lender-specific, confirming the property is adequate security
• Private market valuation: For buying, selling, or general advice on value
• Probate valuation: An independent assessment of value at the date of death for HMRC purposes
• Shared ownership valuation: Required when purchasing additional shares or reselling a shared ownership property
• Capital gains tax: To establish value at a specific historic date
• Matrimonial and legal matters: An independent valuation used as evidence in financial proceedings

Step 2: The site visit

The valuer visits the property to carry out an inspection. This is typically shorter than a full homebuyer survey — the primary goal is to understand the property well enough to form a reliable opinion of value, not to produce a defect-by-defect condition report.

During the visit, the valuer will typically:

• Walk through all accessible rooms and spaces
• Assess the general condition and any significant visible defects
• Note the property’s size, layout, and features
• Consider the location, aspect, and local factors affecting value
• Photograph the property for the report

Step 3: Comparable analysis

After the site visit, the valuer researches recent comparable sales in the area — similar properties that have actually sold, not asking prices. This evidence anchors the valuation in the current market rather than in personal opinion or general estimates.

Step 4: The written report

The valuer produces a written report setting out:

• The property’s description and relevant features
• Market conditions at the valuation date
• The comparable evidence relied upon
• The professional opinion of open market value
• Any caveats or assumptions (e.g., assuming satisfactory structural condition)

RICS valuations follow the Red Book (the RICS Valuation — Global Standards). This means the report is produced to a consistent, internationally recognised professional standard.

When Do You Need a House Valuation?

Buying a property

If you’re buying with a mortgage, your lender will arrange their own valuation. You pay for this as part of the mortgage process, but the report is for the lender — not for you. If you want your own independent view of value before making an offer, you can commission a private valuation.

A private valuation before buying can help if:

• You’re buying at auction and want an independent view of value
• You’re uncertain whether the asking price reflects market value
• The property has unusual features that make comparable pricing difficult
• You’re a cash buyer and there is no lender-commissioned valuation

Selling a property

Estate agents provide free market appraisals, but these are not formal RICS valuations. If you want a truly independent view — perhaps for pricing strategy, insurance purposes, or where there’s a dispute — a RICS valuation gives you objective, professional evidence of value.

Shared ownership

Shared ownership properties require a RICS valuation when you purchase additional shares (staircasing) or when you sell your share. Lenders and housing associations typically require a valuation to be no more than three months old at the time of completion.

Probate

When someone dies, HMRC requires an assessment of the estate’s value for inheritance tax purposes. A RICS valuation at the date of death is the standard way to establish a property’s value for probate. The valuer produces a retrospective valuation based on what the property was worth on that specific date.

Divorce and financial settlements

When a property is part of a financial settlement, an independent RICS valuation provides reliable, impartial evidence of value. Courts and solicitors rely on this to ensure a fair settlement based on actual market data rather than contested estimates.

Capital gains tax

If you’re selling a property that was previously a rental or second home, HMRC may require you to establish the value at a specific historic date (e.g., when you originally acquired it or when it changed use). A RICS valuer can provide a retrospective valuation for this purpose.

House Valuation vs Mortgage Valuation: What’s the Difference?

How Long Is a House Valuation Valid For?

A RICS valuation reflects the market at a specific date. It does not remain valid indefinitely — market conditions change, and so does a property’s condition over time.

In general:

• Mortgage lenders typically accept a valuation that is no more than 3–6 months old, depending on their own policies
• Shared ownership transactions typically require a valuation within the last 3 months
• HMRC (probate and CGT) uses the valuation date as the reference point — the age of the report is less relevant than the accuracy of the date-of-death or acquisition-date figure
• Legal proceedings may have their own validity requirements depending on the case

If you’re unsure whether a valuation is still current enough for your purposes, speak to your solicitor or the RICS valuer who produced the report.

What Affects the Value of a House?

A valuer considers a wide range of factors when forming their professional opinion. The most significant typically include:

• Location: The single biggest driver of value — proximity to good schools, transport links, amenities, and the character of the local area
• Size and layout: Floor area, number of bedrooms, garden size, and whether the layout is practical
• Condition: Visible defects, quality of decoration, age of key systems (heating, electrics, roof)
• Comparable sales: What similar properties nearby have actually sold for in the current market
• Tenure: Freehold properties are typically valued higher than leasehold equivalents; short leases (below 80 years) may significantly reduce value
• Parking: Off-road parking adds measurable value in many locations
• Planning history and restrictions: Any restrictions on use or constraints affecting development potential
• Environmental factors: Flood risk, ground conditions, proximity to noise or industrial activity
