A valuation is about value. A survey is about condition. A RICS valuation tells you what a property is worth on the open market and is used for probate, matrimonial, Help to Buy, tax and dispute purposes. A home survey tells you what condition the property is in, identifying defects and recommending repairs. They are entirely different products produced for different reasons, and one cannot substitute for the other.
This is the single most common point of confusion among buyers, and the most expensive one. Mortgage valuations in particular are frequently mistaken for surveys, leaving buyers exposed to defects no one has actually inspected for.

What a RICS valuation tells you
A RICS valuation is a formal, written assessment of market value, produced under the RICS Valuation Global Standards (the “Red Book”). It tells you:
- The market value of the property as at a specific date
- The comparable evidence used to arrive at that figure
- Any assumptions or special assumptions applied
- The valuer’s opinion of value, signed and dated
It does not tell you whether the roof needs replacing, whether the damp meter readings are concerning, or whether the wiring is safe.
What a home survey tells you
A home survey is a condition report. Depending on the level chosen, it tells you:
- The condition of every major external and internal element
- Where there are defects, what’s wrong (Level 2 and 3)
- Why those defects exist and what to do about them (Level 3 only)
- Any urgent risks to the property, occupants or insurability (Level 3)
It does not tell you the market value of the property unless a valuation is added as a separate service.

The mortgage valuation trap
When you take out a mortgage, the lender carries out a “mortgage valuation” on the property. This is the source of more buyer confusion than anything else in the property market.
A mortgage valuation:
- Is produced for the lender’s benefit, not yours
- Confirms whether the property is adequate security for the loan
- Is often a desktop exercise with no physical inspection at all
- Is not a survey
- Is not a usable RICS valuation for any other purpose
- Is rarely provided to the buyer in full
Many buyers complete a purchase assuming the mortgage valuation acts as both a value check and a condition check. It does neither for the buyer. If you need to know what the property is worth (for any official purpose), instruct a RICS valuation. If you need to know what condition it’s in, instruct a home survey.
When you need a valuation
You need a RICS valuation when:
- Valuing an estate for probate and inheritance tax
- Going through matrimonial settlement
- Selling, redeeming or staircasing a Help to Buy property
- Staircasing a Shared Ownership property
- Supporting a capital gains or asset transfer calculation
- Resolving a dispute (boundary, partnership, beneficiary)
- Valuing property held in a SIPP or trust
A standard buyer purchase, in contrast, normally does not require a separate RICS valuation, because the mortgage lender’s own valuation satisfies their risk assessment.
When you need a survey
You need a home survey when:
- Buying a property, to identify defects before exchange
- Considering significant repairs and wanting to scope the work
- Deciding whether to proceed at the asking price
- Wanting to negotiate the asking price down based on findings
- Buying an older, listed, altered or non-standard property (where a Level 3 is strongly advised)
When you need both
There are several situations where both a valuation and a survey make sense:
- Help to Buy sale. A RICS Help to Buy valuation is required to redeem the loan, but a separate survey may still be useful if you’re buying onward.
- Probate sale. The estate needs a probate valuation, and the buyer of the property needs their own survey.
- Matrimonial sale. The matrimonial valuation establishes the figure for settlement, and the buyer of the property still needs to instruct their own survey.
- Disputed defects. A valuation supporting a price reduction, alongside a Level 3 survey evidencing the defects.
Who carries out each one?
A RICS valuation must be produced by a RICS Registered Valuer (a specific designation). A home survey must be carried out by a RICS-qualified surveyor working to the RICS Home Survey Standard. The two qualifications often overlap, but not always.

FAQs
Does a mortgage valuation count as a survey?
No. A mortgage valuation is a brief lender’s check, not a buyer’s survey. It does not inspect condition systematically, is not provided to you in full, and is not a substitute for a Level 2 or Level 3 home survey.
Can I use a RICS valuation instead of a survey when buying a home?
No. A valuation tells you what the property is worth, not what condition it’s in. For a buyer’s purposes, you need a home survey. If you need both, they can be instructed together.
Is a home survey ever needed for probate?
Generally no, unless there is a dispute over the property’s value linked to its condition, or the property is in poor enough condition to affect probate valuation. A probate valuation alone is usually sufficient.
