Every house sale in England & Wales since 1995 on a map, so that every current home for sale gets compared with what has actually been sold in the area.
Sold prices are public, but everywhere (Rightmove, Zoopla...) shows them one address at a time, as a list, with little sense of when or where. So I built HomesIndex to try and make searching for a home more transparent and easy.
There are three maps on HomesIndex:
Around 188,000 live listings, pulled from around 350 estate agencies' own feeds. Every asking price is put into a band - "Below sold prices" through to "Well above" - based on what similar homes nearby actually sold for over the last four years in the HM Land Registry Price Paid dataset. Similar means the same property type, tenure and size: flats are compared with flats, not with the detached house round the corner, and always against sold prices, not other asking prices.
- Click on a home and it should tell you why it's been put in a certain band, the maths and the number of sales behind that decision.
- If you've seen something on Rightmove or OnTheMarket that the live map doesn't have, paste the property link (or even a list of properties) into the "Add from Rightmove" button and it gets scored the same way.
- You can filter on things the portals don't let you search: freehold only, school within half a mile (primary or secondary), station within a mile (rail or tube), local crime level, and flood risk. Add "below sold prices" on top and you're left with a short list of homes actually worth viewing.
- There's a "Mortgage & rent" button on each property that works out the monthly payment at your own deposit and rate, stamp duty for your buyer type, what it'd likely rent for, the gross yield, and rent minus mortgage.
Type a place or postcode, click a neighbourhood, or drag a rectangle around the bit you care about. Every recorded sale in it appears (although the default is set to show just the last few years, change this in the side bar), about thirty million since 1995, placed at the exact address for roughly 80% of them, so a converted block shows up as its separate flats rather than one dot.
- Click any one and you get its full sale history, plus floor area, price per m², EPC rating, roughly when it was built, habitable rooms, freehold or leasehold, an estimated rent with gross yield, and a photo where one exists.
- Open Price Trends and you get median and average by year with sales volume behind it, and you can put a second area on the same chart to compare by clicking a different area.
- You can export the geolocated data to almost any file type you'd want, to do your own thing with it.

There's a slider back to 1995 and a play button. As you zoom in, the map gets more granular. Press play and the colour spreads outwards from every city centre - thirty years in about twenty seconds.
- An inflation toggle restates every year in today's money.
- Colour by median, average, or how many sales actually happen - useful when you're wondering whether anything in an area is moving at all.
- Click any shape for its median year by year with the number of sales behind each one, plus typical rent and yield.
There's also a load of AI functionality in the "More" tab, where you can ask any question for free and the AI will write you a report about the data.
Where the data comes from: HM Land Registry Price Paid Data, the EPC register, OS Open UPRN, ONS rents and inflation figures, police.uk crime data, Environment Agency and Natural Resources Wales flood data, and the national schools register. All of it is open data - the work was joining it together.
Known limits so nobody wastes their time:
- England and Wales only. Scotland's register isn't open the same way - you have to license it from Registers of Scotland, and it's north of a grand a month.
- The register runs a month or two behind completed purchases, longer for new builds. No website can fix that delay, it is to do with when the land registry data updates
- Flats in a converted house often share one address in the register, so they're hard to tell apart.
- Listings come from 338 agencies and growing - a big slice of the market, but not all of it. The paste-a-link option covers the rest.
Free, no signup, and nobody asks for your details - the only outside links go to the agent actually selling the home.
