London lettings, by the square foot

Every London flat, measured.

The portals won’t let you rank by size. We read the floorplans, so you can.

Sizes are estimates: an AI model reads most of them from the floorplan, and it can be wrong — so can the £/sqft£/m² worked out from them. Check with the agent before you rely on one.

How we know the size

  1. 01

    We collect

    Every new flat to rent in London, checked through the day, seven days a week.

  2. 02

    We read the floorplan

    A vision model reads the plan the way you would — room by room, taking the dimensions printed on it. It is an AI estimate, and it can be wrong.

  3. 03

    We measure

    That gives a square footage, and a price per square foot. You can sort and filter on both. The portal offers neither.
