Valuation
How to Get the Best Property Valuation Possible
The "best" valuation is the most accurate one, not the highest. Get it by combining genuine sold-price comparables (HM Land Registry, Rightmove, Zoopla), two or three estate-agent valuations (judged on evidence, not the biggest number), and — for certainty or a complex/high-value home — a RICS surveyor’s valuation. Beware agents who inflate the figure to win your instruction; an accurate price sells faster and often for more than an optimistic one.

Start with sold comparables
The foundation of any good valuation is what similar homes actually sold for — not asking prices, which are aspirations. Use HM Land Registry Price Paid Data (surfaced on Rightmove and Zoopla as "sold prices") to find recent sales of homes matching yours on type, size, condition and street, ideally within the last 6-12 months. Average three to five close matches and adjust for differences. This gives you an evidence-based figure to test agent valuations against (see finding comparables).
Get multiple agent valuations
Invite two or three local agents to value the home, and treat it as an interview. Ask each to justify their figure with sold comparables, and note their average time-to-sell and asking-to-achieved ratio. Expect a spread — but be wary of the outlier quoting far more than the others, which is often a tactic to win the instruction before pushing for reductions. The agent whose figure is backed by evidence, not optimism, is usually the most useful.
When to use a RICS valuation
For an independent, authoritative figure — useful for probate, divorce, tax, a high-value or unusual property, or simply peace of mind — commission a RICS "Red Book" valuation from a chartered surveyor. Unlike an agent appraisal (a marketing exercise) or an automated online estimate (an algorithm), a RICS valuation is a professional, impartial opinion of value that carries weight with HMRC, courts and lenders. It costs a few hundred pounds but removes guesswork where it matters.
Valuation methods compared
| Method | Accuracy | Best for |
|---|---|---|
| Online estimate (AVM) | Rough (±10-20%) | A quick starting range |
| Sold comparables | Good | Pricing your own sale |
| Estate-agent appraisal | Variable | Marketing strategy; cross-check |
| RICS valuation | High, impartial | Probate, divorce, tax, complex homes |
Avoid the over-valuation trap
The "best" valuation feels like the highest one — but over-pricing is the single biggest cause of a slow sale. An inflated figure wins the agent your instruction, then the home sits, the days-on-market climb, and it ultimately sells for less than a correctly priced one would have. The genuinely best outcome comes from pricing to evidence. If you also want to know your home’s quick-sale value, compare cash offers against your accurate market figure — a genuine cash buyer pays around 75-85% (see what cash buyers pay).

Frequently asked questions
Straight answers, no sales talk
How do I get the best property valuation?
Combine genuine sold-price comparables, two or three agent valuations judged on evidence, and a RICS surveyor’s valuation for certainty or complex homes. The best valuation is the most accurate, not the highest.
Are online house valuations accurate?
Only roughly — automated models can be 10-20% out either way because they cannot see your home’s condition or improvements. Use them as a starting range, not a valuation.
Should I trust the highest agent valuation?
Be cautious. The highest figure is often a tactic to win your instruction, followed by pressure to reduce. The most useful valuation is the one backed by sold comparables.
What is a RICS valuation?
A professional, impartial opinion of value from a chartered surveyor, following the RICS "Red Book". It carries weight with HMRC, courts and lenders, useful for probate, divorce or tax.
How many valuations should I get?
Two or three agent valuations plus your own sold-comparable research. For complex or high-value homes, add a RICS valuation for an authoritative figure.
Does an accurate valuation help me sell faster?
Yes. Pricing to evidence attracts competing interest and a quicker, stronger sale, whereas over-pricing lengthens days-on-market and often achieves less.
