London property market 2026 - What Thai investors need to know

London's property market found a steady rhythm in the initial months of 2026. Prices are climbing, but slowly; sales are holding up; and mortgages, finally, are getting a little more affordable. For Thai investors keeping an eye on London, none of this is dramatic: it's the market settling into itself again and that's worth understanding properly.

Prices are rising, but the pace is deliberate

The May 2026 house price index showed a 1.2% monthly rise in average new seller asking prices, higher than the typical 1% recorded in May over the past decade. London grew more modestly, at 0.8%, adding just over £5,000 to the average home. That average is now £685,347, well above the UK-wide figure of £378,304.

Besides, in May 2026, the average first-time buyer home in London crossed £500,000 for the first time. It's a sign that demand in the capital hasn't gone anywhere, even while the wider market works through its correction. For Thai buyers specifically, sterling's position against the baht over the past 18 months has made London property easier to reach.

Sales are up, even as buyer demand eases

UK-wide, agreed sales in May 2026 were up 1% year-on-year, even though buyer demand actually fell by 10%. London led the race with agreed sales up 8% year-on-year. Supply is also strong: there are 13% more homes on the market than a year ago and that extra stock is keeping price growth stable. To put it simply: the market has more balance now than it's had in years.

Mortgage rates and the Bank of England's position

The Bank of England held its base rate at 3.75% at the April MPC meeting. Mortgage rates followed suit; the average two-year fix eased from 5.42% in April to 5.18% in May. Inflation dropped too, down to 2.8% from 3.3% the month before.

But affordability improving even slightly tends to build buyer confidence and that confidence eventually shows up in transaction volumes and price stability. Thai investors buying with cash or overseas mortgage arrangements won't feel the UK rate changes directly. It is still a stronger domestic buyer pool is good news for resale value and rental demand down the line.

The rental market: steady growth, London still commands a premium

UK rents grew 3.5% in the 12 months to April 2026, according to ONS data, just above the 3.4% recorded the month before. London actually posted the lowest regional rental inflation, at 2%. Even though average rents in the capital still sit at £2,290 a month, over 60% higher than the UK average of £1,438.

Month-on-month, London rents rose 1.7% in April. For Thai investors already holding property here, that's more confirmation of what London rental income has consistently been reliable.

The Renters' Rights Act: what landlords need to know

The Renters' Rights Act became law in May 2026 and it introduced no-fault evictions, limits on how often rent can be raised, bidding bans and the structure of tenancy agreements themselves.

Benham and Reeves has been navigating London's lettings landscape for over 65 years and this is exactly where that experience helps global investors. Across our 21 London branches, plus offices overseas, including in Thailand, we help landlords, local and overseas, stay compliant and informed as this legislation beds in.

Pricing strategy affects how quickly a property sells

A figure that stands out in 2026 is how quickly correctly priced homes sold in 36 days on average. Homes that needed a price cut took 127 days, more than three times as long. Right now, close to a third of all listed properties are seeing reductions. Overpricing is still one of the most common and costliest mistakes sellers make.

Reading the market as a Thai investor

London in 2026 looks like a strategic investment market with measured price growth, stable rental income, recovering sales volumes and legislative change being absorbed with the right guidance in place.

Thai investors tend to enter London property at the mid-to-upper end of the market and that's exactly where informed, well-timed decisions pay off most. Benham and Reeves Thailand supports overseas buyers at every stage, from the first purchase through to lettings management and ongoing compliance.
