The most expensive places to live in London (2026)

1. The Banana Zone — London's prime arc

Trace London's most expensive boroughs on a map and they form a rough arc curving west to north across the centre: Kensington and Chelsea, Hammersmith and Fulham, Westminster, Camden, Islington. Buyers and agents have called it the Banana Zone for years. Here is what the data shows today.

• •Kensington and Chelsea leads at an average price of £1,399,538: flats average £904,417 across 927 transactions; houses average £3,512,075 across 219 transactions. Westminster follows at £968,067, then Camden at £867,539.
• •Hammersmith and Fulham at £820,714 and Islington at £783,068 complete the arc: both have active flat markets alongside expensive houses. The average flat price in Islington (£586,062) is higher than the average price of any property type in roughly half of London's boroughs.

2. To buy a flat here, you need a household income above £134,000

• •At a 4.5× income multiple with a 10% deposit, a K&C flat requires £180,883 household income: Westminster needs £154,142, Camden £132,535. Monthly repayments at 3.97% over 25 years: £4,283 for K&C, £3,650 for Westminster. For comparison, a Barking flat costs £1,102/month.
• •Houses are a different market entirely: the K&C house average is £3,512,075, requiring £702,415 household income on a standard mortgage. Westminster's house average is £2,283,630. These properties are largely bought without mortgage financing.

3. Over half of K&C sales are above £1M. Prices are still falling.

• •52.0% of K&C transactions in the past 12 months were above £1M: Westminster at 36.7%, Camden at 30.0%. More than one in two sales in K&C is above the luxury threshold — by a wide margin the highest concentration in London.
• •Despite that, all five arc boroughs are down year-on-year: Westminster -10.9%, Hammersmith -8.1%, Camden -6.1%, K&C -1.7%, Islington -1.0%. Over the same period, Waltham Forest rose 6.4%, Enfield 3.0%, Redbridge 2.5%. The softening is prime-specific, not London-wide.
• •The April 2025 stamp duty changes hit prime transactions hardest in absolute terms: a £3M house now carries materially more tax than it did in 2024. Combined with weaker international buyer demand through 2025, the top end of the market has repriced.
