Where do these numbers come from?
Asking rents, not agreed rents. Every whole-home London listing that RentReboot first saw in the 90 days to 17 October 2026, one listing per address (the newest wins, so a flat advertised on several sites counts once). Rooms in flatshares are excluded. A bedroom group with fewer than 10 listings is not shown. London listings often give a street but no flat number, so one address can stand for more than one flat on the same street.
