London’s super-prime market’s tail is on the up with a rise in billionaires purchasing homes valued above £15 million in the first six months of year, but they remain well below the levels in 2024.
Mid-year research carried out by luxury real estate agent Beauchamp Estates shows that there was £1.24 billion worth of property sold (34 deals) in H1 2026, compared to £694.1 million of sales (27 deals) during the same period in 2025.

The wealth survey reveals that an influx of wealthy cash buyers from the US and the Middle East drove the 79% rise in the combined sales value achieved (26% rise in sales by unit numbers).
The figures are in line with realtor’s market forecast at the start of the year, with the annual ‘Billionaire Buyers’ report predicting that international buyers will represent the largest portion of London’s super prime property purchasers in 2026.
London’s super-prime market is still glossy
What’s driving this shift isn’t renewed optimism about London, but opportunity. According to data, “financially astute” US and Gulf buyers now account for 55% of all prime central London £15 million-plus sales, a surge that signals a distinct “bargain hunt” strategy rather than an emotional return to the capital.
These investors are capitalising on a unique liquidity window created by the exodus of non-dom sellers. With prestige postcodes such as Belgravia and Mayfair effectively repriced by the availability of high-end stock, buyers are moving to secure assets before broad-market recovery begins.
Quality assets, attractive pricing, prestige postcodes, scale and improved availability are some of the variables inveigling bullish international wealth, with American buyers in particular motivated by the booming American economy and AI/tech sector. US investors now account for 30% of all £15 million-plus PCL sales, according to the estate agent.
Wealth cycling out of the Middle East and towards more ‘neutral’ wealth hubs such as London has led to a significant influx of capital from the Gulf states into the London real estate market in a bid to diversify portfolios and refocus investment strategies.
Gulf buyers, predominantly from the United Arab Emirates, Saudi Arabia, Kuwait and Oman accounted for 25% of all ultra-prime sales across the UK capital, predominantly snapping up London’s trophy mansions in which to wait out regional unrest.
London remains a safe haven for international wealth
Buyers from India/South Asia accounted for 15% of ultra-prime sales, sales to buyers from the UK stood at 14%, while buyers from Eastern Europe represented 7% of all big-ticket transactions.
Western European buyers accounted for 5% of sales and Africa/other 4%. By country of origin the largest group of African buyers are wealthy Nigerian families who in 2026 have returned to the London property market after a hiatus of several years.
American interest is particularly indicative of this strategic pivot. Driven by the strength of the US tech and AI sectors, these investors are leveraging current currency advantages and pricing discrepancies to secure trophy assets.
Simultaneously, wealth cycling out of the Gulf states is seeking refuge in stable, neutral hubs. For these buyers, London’s trophy mansions serve a dual purpose: they are assets for portfolio diversification and secure, long-term shelters against regional instability.
By acting decisively now, this cohort is effectively testing the floor of London’s super-prime market, betting that quality and long-term utility will continue to decouple from broader UK political uncertainty.
Looking ahead, Savills expects price growth to return from 2028 onwards, while a gradual recovery in values is predicted over the two-year period.
This creates a strategic window for investors to invest in well-priced prime and ultra-prime London stock as evidenced by the jump in transactions within London’s top rungs of the trophy real estate market.
London's billionaire monopoly board
Back in January, Beauchamp Estates predicted that PCL postcodes will lead demand as supply lags with ‘addresses of choice’ for the super-rich Belgravia, Knightsbridge – both winners in 2025 – and Mayfair seeing the highest interest among high-net-worth buyers looking for a London base.
Their predictions still hold six months on. The capital’s most in-demand address is Belgravia which in the first six months of 2026 has had nine £15 million-plus sales, compared to just two during the same period in 2025.
For American buyers, particularly those who work in AI, tech or finance sectors, Mayfair is their most sought after address.
According to the agent, Mayfair has become London’s “Silicon square” – the leading hub for boutique AI/tech, fintech and private equity firms in the capital with over 165 fintech companies and around 200 private equity firms based in the glossy postcode.
“Popular addresses among American, Nigerian and Eastern European buyers also include Notting Hill and Bayswater, which have had three £15 million plus sales during 2026.”
Another big winner – a reflection of the current strong buyer demand for freehold family houses – has been St John’s Wood. Five £15 million-plus sales have taken place during 2026 with the most popular addresses being mansions on Avenue Road and Hamilton Terrace – the district’s two ‘billionaire addresses’.
Popular addresses among American, Nigerian and Eastern European buyers also include Notting Hill and Bayswater, which have had three £15 million plus sales during 2026.
They include the £57 million sale of the penthouse at the Park Modern apartment building overlooking Hyde Park, the trophy home purchased by tech billionaire Igor Babuschkin, Elon Musk’s xAI co-founder.
Another success story, arguably the most spectacular, is Chelsea. There have been five £15 million+ sales in the district, including the £275 million sale of mega-mansion Providence House set in two acres of gardens. The purchase is the most expensive house sale ever undertaken in London.
What are billionaires buying in London?
Ultra-high-net-worth buyers are prioritising priced-to-sell large freehold houses or mansions set in landscaped gardens, according to the agent. Between January and June, 24 freehold houses priced over £15 million sold, generating combined sales worth £977 million.
Those purchasing apartments are selecting larger footprint “turn-key” family apartments (three to five bedrooms) or penthouses located in newly built luxury developments offering concierge and hotel-style amenities.
Beauchamp Estates says the preference for large apartments is a smart investment strategy reflecting planning restrictions in the City of Westminster, now limiting new apartments to under 2,152 square feet in size.
Forward-thinking investors have been acquiring larger units for their rarity value and enhanced potential resale value. Eight apartments priced over £15 million were acquired across the six-month period.
“The demand for second-hand homes requiring refurbishment has been small, apart from a few trophy mansions where buyers perceive capital value uplift potential once refurbishment has been undertaken.”

Of the 34 deals, 22 were for homes sold for values between £15 million to £25 million; a further seven sold from £26 million to £50million; three deals at values between £51 million to £100 million; and two sales for values in excess of £100 million.
The top five highest-value London ultra-prime sales in the first half of the year were Providence House in Chelsea, sold for £275 million, The Holme in Regent’s Park, sold for £195 million, the penthouse at Park Modern (£57 million), a Knightsbridge mansion on Thurloe Place (£55 million) and a penthouse at Chelsea Barracks (£36.5 million).
