Americans currently account for 30% of all £5m+ sales in Prime Central London (PCL), up from 20% at the end of 2025.

This is according to high-end agency Beauchamp Estates. 

It says the majority of American buyers work in AI or other tech sectors, or in fintech or private equity.

The agency claims Mayfair – where over 165 fintech and 200 private equity firms are based – is their preferred location. 

As you go up the asking price scale, so Americans dominate further. 

They currently account for 50% of all luxury homes sales above £5m in Mayfair, followed by purchasers from the Gulf (United Arab Emirates, Saudi Arabia and Kuwait) who account for 25% of all Mayfair sales and 20% of all PCL sales. 

Together, USA and Gulf buyers account for 50% of sales in the luxury homes market in London, and 75% in Mayfair, the capital’s poshest address. 

After Mayfair, the next two most favoured addresses with American and Gulf buyers are Belgravia and Knightsbridge. 

Beauchamp says the majority of purchases in Mayfair have been lateral apartments in either new luxury developments located around Grosvenor Square and Curzon Street, or newly refurbished apartments with contemporary specification located in buildings with retained Georgian or Victorian facades. 

Both American and Gulf buyers are seeking “turn-key”, fully dressed and interior designed London homes which they can occupy immediately. 

Jeremy Gee,the agency’s managing director, says: “All the biggest deals over the last six months have been to either wealthy American or Gulf families. 

“The booming American economy and the Gulf crisis has benefited the London real estate market which is viewed as providing value-for-money, an opportunity to acquire bargains and purchase outstanding trophy homes.”
