Propbar is a browser extension that turns UK property portals into a research desk. Instead of reading Rightmove, Zoopla or OnTheMarket listings in isolation, you get the underlying public record alongside them: sold prices and every recorded price change, days on market, agent details, historical photos and floor plans, current and past EPCs, planning constraints, planning applications nearby, local HMO registers and ONS-based demographics. An AI summary condenses the essentials into a short, scannable block.
The extension is one entry point into a broader Propbar platform operated by Vepler ltd, a London-registered company. The same data powers a search-and-report website covering addresses, postcodes and areas across the UK, a Map Explorer with 40+ filters for professionals, a free EPC checker, a true-cost-of-buying calculator and a widget that agencies can white-label. Records are drawn from named official sources including HM Land Registry, the EPC Register, the Environment Agency, Ordnance Survey, police.uk, ONS census data and the Department for Education rather than scraped listings.
Propbar positions itself as independent of agents and portals, aimed at home buyers, sellers, owners, renters, landlords, solicitors and property investors. Coverage is complete for England and Wales, partial for Scotland and not yet available for Northern Ireland. The extension is free to install; deeper valuation, comparables and risk material sits behind the paid Plus plan on the web platform.
