London’s super-prime property market is undergoing a quiet but seismic reshuffle, as wealthy UK-based sellers trade in their mansions for pieds-à-terre and new lives abroad…

As reported by The Real Deal, a new study from Beauchamp Estates reveals that nearly 70 percent of those selling homes valued over $20 million in London this year are high-net-worth individuals (HNWIs) who now list their main residence as being outside the UK.

Rather than panic selling, this marks a broader strategic shift among London’s elite. Many are offloading their trophy homes in the British capital to diversify into cities like Miami, Milan, Dubai, Monaco, and the South of France; global hubs offering lifestyle appeal, warmer climates, and tax advantages. In return, international buyers, particularly those from the Gulf states and the US, are snapping up these ultra-luxury properties, often spending between $32 million and $64 million, with some deals soaring beyond $190 million.

Despite a 13 percent year-on-year drop in ultra-luxury sales volume in the first half of 2025, the pace has steadied from the steeper 23 percent decline seen the year prior. The second quarter alone accounted for 60 percent of all ultra-prime transactions so far this year.

Beauchamp’s Jeremy Gee calls it a “once in a generation” buying window, with prices still sitting below 2014 highs. Wealthy domestic and international buyers now make up roughly 50 percent of all transactions, signalling renewed confidence in the London market—just not necessarily as home.
