This is what you see while booking.

Example listing cards with the badge the extension adds to real Airbnb and Booking.com search results. The scores are live — computed from July 2026 police data — and clicking a badge opens the area's full report, exactly as it does in the extension.

What it does

Every London listing card gets a colour-coded badge: an indicative 0–100 safety score and a caution level (Low, Normal, or Elevated) for the neighbourhood the stay is in. Hover a badge for the ward, borough, and the month of the underlying police data. Searches outside London are left untouched.

How to use it

There is nothing to configure: search London stays on Airbnb or Booking.com as usual and the badges appear on the result cards. Click any badge to open the area's full free report here — recent crime trends, transport links, and safer nearby alternatives. The extension icon's popup lets you switch either site off.

Where scores come from

Scores for all ~700 London electoral wards are computed nightly from UK Police open data, anchored to official deprivation statistics — the same methodology as every report on this site. They are travel-planning context, not a guarantee of personal safety.

How to install

The extension is on the official Chrome Web Store and installs in one click in Chrome or any Chromium browser that supports Web Store installs (Edge, Brave, Opera):

  1. Add it from the Chrome Web Store

    One click, no sign-up, no configuration. The Then Travel shield appears next to the address bar.

  2. Search London stays as usual

    Browse Airbnb or Booking.com search results and every London listing card gets its safety badge automatically.

  3. Click a badge for the full report

    Any badge opens the area's free report on this site — recent crime trends, transport links, and nearby alternatives.

Privacy

The extension collects no personal data — no browsing history, no account, no analytics, no cookies.

It makes one kind of network request: downloading the public, read-only ward-score dataset from london.then.travel (cached in your browser and refreshed every six hours). Matching listings to neighbourhoods happens entirely on your device; nothing about your searches or the listings you view is ever transmitted anywhere.

The badges are free for everyone. If a paid tier for on-demand detailed reports is introduced later, payments would be handled by a dedicated provider and this policy will be updated first.

Prefer to check one address?

You can run any London stay through the full report without installing anything.
