Overview
Sold price records, when used carefully, can anchor what a property is worth before you bid. The disciplined workflow is simple: define the target and filters; gather official sold price evidence; normalise and adjust comparables into a like for like range; then convert that into a clear offer and walk away line.
Official coverage is strong but varies by nation. England and Wales use HM Land Registry’s Price Paid Data. Scotland publishes address level sold prices via Registers of Scotland’s ScotLIS and statistics from registrations received. Northern Ireland does not publish address level sold prices; instead, the Land & Property Services and NISRA publish the Northern Ireland House Price Index. Know what each dataset includes, how often it updates, and where it has gaps. Build a small, defensible set of comparables and adjust them transparently with simple numbers.

Worked examples
These examples show the arithmetic and the adjustment sequence. Replace index moves, local reference values and any lease figures with your current local data from the cited sources.
Example 1: freehold house, England using HM Land Registry Price Paid Data
Target: freehold 3 bed semi, 95 m², average condition, no parking issues, Suburb A, England. Valuation month: April 2026.
Filters: semi detached, freehold, 80 to 110 m², 0.5 mile, transfers completed May 2025 to March 2026, exclude Category B.
Gather three strong comparables from Price Paid Data: Comp 1: 92 m², sold 15 Oct 2025 at £412,000. Comp 2: 99 m², sold 20 Nov 2025 at £430,000. Comp 3: 101 m², sold 10 Jan 2026 at £440,000.
Time adjustment using local UK HPI. Suppose index change to April 2026 from each sale month is: Oct 2025 to Apr 2026 +1.0 percent; Nov 2025 to Apr 2026 +0.8 percent; Jan 2026 to Apr 2026 +0.2 percent. Adjusted prices: Comp 1: £412,000 × 1.010 = £416,120. Comp 2: £430,000 × 1.008 = £433,440. Comp 3: £440,000 × 1.002 = £440,880.
Size adjustment to 95 m² using £ per m²: Comp 1: £416,120 ÷ 92 = £4,522/m²; scaled to 95 m² = £429,590. Comp 2: £433,440 ÷ 99 = £4,378/m²; scaled to 95 m² = £415,910. Comp 3: £440,880 ÷ 101 = £4,364/m²; scaled to 95 m² = £414,580.
Value range and offer: sort £414,580, £415,910, £429,590 → median £415,910; 25th percentile approx £414,580; 75th approx £429,590. Evidence range: about £415k to £430k; midpoint about £421k. Offer decision: in a balanced market, open at £418k with proof of funds and timetable, aim to agree below £423k. Walk away at £427k given comps and small time uncertainty.
Example 2: leasehold flat, London with lease and charges adjustments
Target: leasehold 2 bed flat, 62 m², 5th floor with lift, unexpired lease 78 years, service charge £3,500 per year, Zone 3 borough. Valuation month: April 2026.
Filters: flats in the block or immediate micro area, leasehold, 55 to 70 m², 0.25 mile, last 12 months, avoid new build with incentives if possible.
Gather three strong long lease comparables from Land Registry (assume 110 to 125 years): Comp A: 60 m², 120 year lease, sold Oct 2025 at £410,000. Comp B: 64 m², 110 year lease, sold Jan 2026 at £420,000. Comp C: 63 m², 999 year lease, sold Sep 2025 at £415,000.
Time adjustment to April 2026 using local UK HPI: assume +0.5 percent from Oct 2025; +0.2 percent from Jan 2026; +0.8 percent from Sep 2025. A: £410,000 × 1.005 = £412,050. B: £420,000 × 1.002 = £420,840. C: £415,000 × 1.008 = £418,320.
Size adjustment to 62 m²: A: £412,050 ÷ 60 = £6,867/m² → × 62 = £425,754. B: £420,840 ÷ 64 = £6,576/m² → × 62 = £407,712. C: £418,320 ÷ 63 = £6,644/m² → × 62 ≈ £411,928. Long lease baseline value: median of £425,754, £407,712, £411,928 → £411,928.
Lease shortness adjustment: estimate a statutory lease extension premium and related professional costs for 78 years and subtract this from the long lease baseline. For illustration, assume a specialist’s written estimate totals £22,000 including professional fees. Adjusted value: £411,928 − £22,000 ≈ £389,928. Below 80 years, historic rules created additional costs via marriage value; LEASE notes many 2024 Act measures are not yet in force, so confirm current law and premium with your adviser.
Service charge differential: target £3,500 per year versus comparables around £2,500 per year. A pragmatic buyer adjustment is to capitalise the £1,000 per year difference over a five year holding horizon, giving about a £5,000 discount. New adjusted value ≈ £384,900.
Offer and lender check: evidence range around £380k to £390k after adjustments; open at £382k, aim to agree at or below £388k. If you bid materially above your evidenced range, expect a down valuation and lending based on the lower of valuation or purchase price, creating a potential funding gap.

Glossary
- Asking price
The seller’s stated price on a listing.
- Guide price
An indicative marketing or auction guide that may change; not a firm asking or reserve.
- Sold price
The price recorded on completion and registered; in HM Land Registry Price Paid Data it is the price stated on the transfer deed and the Date of Transfer is the completion date.
- Completion date
The legal completion of the transfer when ownership changes and keys are released.
- Transfer date
For HM Land Registry Price Paid Data this is the completion date shown on the deed lodged for registration.
- Comparable sale (comp)
A broadly similar, recently completed sale used as evidence.
- Radius and time window
The geographic and temporal limits you set to select comparables.
- Price per square metre
Sale price divided by internal area; ONS publishes reference statistics for England and Wales.
- Tenure
Freehold or leasehold.
- Lease length
Unexpired years remaining on a lease; sub 80 years may carry additional value and lending implications under current law and practice.
- Incentives
Financial or non financial benefits provided by a seller or developer that affect the true consideration; must be disclosed and adjusted.

What HM Land Registry Price Paid Data includes and excludes
HM Land Registry’s Price Paid Data includes residential property sales in England and Wales that are sold for value and lodged for registration; it records the sale price as stated on the transfer deed and the Date of Transfer is when the sale completed. It excludes sales not lodged, sales not for value, and certain transfers such as gifts, Right to Buy discounts, and court orders; leases of 7 years or less are not recorded.
Scotland and Northern Ireland sold price coverage and key differences
Registers of Scotland provides individual sold prices via ScotLIS and compiles statistics from registrations received; where identified, non market value transfers are excluded. Northern Ireland does not publish an address level sold price register; official statistics are published as the NI House Price Index on a quarterly schedule by LPS/NISRA.
New build incentives and why headline sold prices can mislead
RICS guidance requires valuers to identify and adjust for new build incentives because they can distort headline prices relative to market value; lenders require the UK Finance Disclosure of Incentives form in new build transactions. When using a new build sold price as a comparable, subtract disclosed incentives to avoid overvaluation.
