The average London tenant now pays £2,338 a month, according to the ONS, up 3.5% on a year earlier (September 2026). That figure covers every private tenancy, including long-standing ones, so anyone searching for a new home today should expect to pay more.
Asking rents tell that story. Rightmove's Q3 2026 tracker put the average advertised London rent at a record £2,825 a month, up 3.2% year on year. Supply is the main reason: available rental homes in the capital are down 9% on last year while renter demand is up 6%.
Postcode matters as much as the city-wide average. The ONS figure for Kensington and Chelsea alone is £3,739 a month, the highest of any local area in the UK. At the other end, outer east and south-east London still offer rents well below the capital's average.
This guide uses three measures, so it is worth knowing what each one counts:
- ONS (Price Index of Private Rents): what tenants actually pay, new and existing tenancies, by borough.
- Rightmove: asking rents on newly listed whole homes.
- SpareRoom: asking rents for a single room in a flatshare, bills included, by postcode district. It is the most detailed postcode-level data published, so it anchors the area-by-area sections below.
Central London: W1, SW1, WC and EC
Central postcodes remain the priciest in the capital, and they are rising fastest. WC is now London's most expensive postcode area for a room, at £1,464 a month in Q3 2026, up 7.3% on a year earlier. EC follows at £1,289, up 5.2%.
At district level, W1 (West End and Soho) averages £1,519 for a room, WC1 (Bloomsbury and High Holborn) £1,447, SW1 (Westminster, Belgravia and Pimlico) £1,280 and EC1 (Finsbury and Clerkenwell) £1,273. Supply is the pressure point: WC room listings fell 30% in a year.
For whole homes, Rightmove's average inner London asking rent was £3,299 a month in Q2 2026, against £2,418 in outer London.
West and south-west London: SW and W
SW7 (South Kensington and Knightsbridge) is London's single most expensive postcode district, with an average room rent of £1,682 a month, up 13.3% in a year. Neighbouring SW3 (Chelsea) jumped 16.6% to £1,472, and SW5 (Earl's Court) rose 12.4% to £1,397.
Across the whole SW area, rooms average £1,065, a record high. The W area sits close behind at £1,064, with W8 (Holland Park) at £1,340 and W2 (Bayswater and Paddington) at £1,279.
Not everywhere in the west is climbing. W8 fell 7.1% year on year, W11 (Notting Hill) dropped 5.3% to £1,117, and SW13 (Barnes) slipped 4.4% to £938.
North and east London: N, NW and E
East London is the capital's cheapest postcode area, at £958 a month for a room, and its rents barely moved (+0.4%) over the year. North London averages £969 and north-west £999.
NW1 (Camden) is the exception in the north, at £1,248 a month. N5 (Highbury) costs £1,042 but fell 4.6%, while N2 (East Finchley) jumped 10.6% to £950.
The east holds most of London's last sub-£800 rooms: E12 (Manor Park) at £752, the cheapest district in the capital, then E6 (East Ham) at £755, E7 (Forest Gate) at £781 and E13 (Plaistow) at £789. In the north, N21 (Winchmore Hill) fell 17% to £761 and N9 (Lower Edmonton) averages £790.
Borough-level ONS data points the same way: Barking and Dagenham, Havering, Bexley and Sutton are consistently among the cheapest boroughs to rent a whole home.
South and south-east London: SE
South-east London averages £963 a month for a room, a record for the area, but it is where the sharpest local rises are happening. SE19 (Crystal Palace) is up 11.7% to £923, SE17 (Walworth) up 11.1% to £1,132, SE21 (Dulwich) up 10.9% to £935 and SE7 (Charlton) up 8.6% to £899.
Value remains further out. SE9 (Eltham) averages £810 and SE28 (Thamesmead) £822, both among the ten cheapest inner London districts. SE14 (New Cross) moved the other way, falling 4.5% to £933.
For whole homes, outer London's average asking rent of £2,418 (Rightmove, Q2 2026) is roughly £900 a month below inner London's.
What's driving prices, and how to rent smarter
Shrinking supply is the main driver. Room listings in inner London fell 7.3% in a year, and Rightmove says London is seeing a sharper supply squeeze than the rest of Britain. Higher mortgage rates continue to deter new landlords, while the Renters' Rights Act has ended bidding wars and limited rent rises to once a year.
A few practical points for 2026 searches:
- Look one stop further out. Moving from SW7 to an SE or E district can halve a room's rent.
- Watch the risers. Crystal Palace, Walworth and Dulwich are no longer the bargains they were a year ago.
- Budget on asking rents, not averages. New lets run well above the ONS all-tenancy figure.
- Check what's included. SpareRoom figures include bills; whole-home rents usually don't.
