The Postcodewise Browser Extension Is Live: Instant Area Reports on Rightmove, Zoopla, OnTheMarket, PrimeLocation and OpenRent

Property portals tell you about the house. They say very little about the street it sits on. Until now, answering "is this a good area?" meant opening a new tab for every listing and copying the postcode into a report.

The Postcodewise browser extension is now live, and it removes that step. Browse a listing and a side panel opens beside it with the area intelligence for that postcode, already loaded.

What it does

When you open a listing on a supported portal, the extension reads the address and postcode from the page and loads the matching Postcodewise report in a side panel. There is nothing to copy, paste or search.

The panel opens on an Overview with the overall score, the postcode, local authority area, region and country, and, where the listing shows one, the asking price. Below that are at-a-glance scores for crime, schools, transport, environment and affluence, with a data-confidence indicator so you can see how much to trust each figure. Tabs take you deeper into each topic.

Where it works

Listings are detected automatically on:

• Rightmove (rightmove.co.uk)
• Zoopla (zoopla.co.uk)
• OnTheMarket (onthemarket.com)
• PrimeLocation (primelocation.com)
• OpenRent (openrent.co.uk)

For sales and lettings alike, the panel updates as you move between listings.

What you see

Every figure comes from official open-government sources, the same data behind our full postcode reports.

Install it

The extension is built for Chromium browsers that support the side panel, including Google Chrome (114+), Microsoft Edge (114+), Brave, Arc and Opera. It is available on the Microsoft Edge Add-ons store, and every install option is listed on the extension page.

1. Install the extension from the extension page.
2. Open any listing on a supported portal.
3. Click Connect Account in the side panel to link your Postcodewise account in one click.

Free, and private by design

The extension is free to use. Free personal accounts receive monthly complimentary report credits, and Pro and Business subscribers have unlimited lookups.

It only runs on the supported property portals. It does not track your browsing history, and it talks only to the official Postcodewise API. Your sign-in token stays in your browser's private storage.

Try it on your next viewing

Open a listing you are already considering, look at the crime, schools and transport scores, and decide whether it earns a viewing before you pick up the phone. Get the extension.
