One postcode in. A defensible Excel report out - 48 configurable columns: Land Registry sold prices, HPI-indexed to today, price per sqm, plus planning and flood context. Every row verifiable at source.
From postcode to professional Excel report in three simple steps.
Input your scheme postcode, then choose property types, search radius, date range and filters.
We pull Land Registry transactions, match EPC floor areas and index to current values with HPI, then overlay planning, flood, crime, schools and transport - all automatically.
Get a professional Excel file - up to 48 configurable columns of current-day indexed values, price per sqm and sqft, and Land Registry verification links on every row.
We cross-reference official UK government open data and layer locality signals on top to build the most accurate comparables list possible.
Price Paid Data - every residential property transaction in England and Wales.
Energy Performance Certificates - floor area data for size-based analysis and price per square metre calculations.
ONS House Price Index - indexes historical sold prices to current-day values at local authority level.
Planning, risk and amenity context attached to every comparable so you can defend the choice of comparables, not just the price.
A comparables run that used to eat half my morning now takes under a minute - and every figure links back to the Land Registry. My reports have never been easier to defend.
No black boxes. Bartons Lens shows its workings - source data, indexation and verification links - so your professional judgement stays front and centre.
A 2016 sale, restated at today's value - automatically, at local authority accuracy.
Direct links to the original Land Registry transaction. Fact-check any figure in one click.
Postcode sector, district, area - or true radius search up to 10 miles.
New builds, existing stock, freehold & leasehold.
Listed buildings, conservation areas, flood zones and crime - flagged per comparable.
Multi-user access and a JSON API with long-lived tokens for full automation.
HPI indexation and £/sqm out of the box is exactly what I needed. It follows the methodology I would use manually - just instantly and consistently.
We run it through the API across the whole team. Planning and flood overlays per comparable save us a mountain of separate lookups.
One residual valuation covered the annual subscription. The Land Registry links on every row are what convinced our compliance team.
Every paid plan includes the full, configurable 48-column Excel output and every locality layer.
