Back in 2014, the property market in London was booming with international investment and new-build developments, to name just a few.

A new report from Black Brick, the leading London buying agency, charts the dramatic transformation of London’s prime property market between 2014 and 2025 — from a seller’s peak to a buyer’s market defined by negotiating power, shifting demographics and evolving location preferences.
From Seller’s Market to Buyer’s Advantage
The contrast between 2014 and 2025 could scarcely be starker. Where buyers once secured average discounts of under 4% against asking price, Black Brick’s agents are now achieving average savings of £612,386 — representing an 8% discount. Off-market transactions have also surged, rising from half of all acquisitions in 2014 to nearly three-quarters in 2025.
New-Builds Fall Out of Favour
One of the most striking shifts has been the collapse in demand for new-build homes. New-builds accounted for 56% of Black Brick’s acquisitions at the market’s peak; by 2025, that figure had fallen to just 16%.
Camilla Dell, Founder and Managing Partner at Black Brick, explains: “New builds might have gone out of favour in this weaker market, because people are looking for value for money” — pointing to service charges and upfront premiums that are harder to justify when capital growth is uncertain.
Owner-Occupiers Now Drive Prime London
The investment-led buying that characterised 2014 has largely given way to lifestyle-driven purchasing. Just 11% of Black Brick’s 2025 acquisitions were investment purchases, compared with 40% in 2014 — a clear signal that prime London is now predominantly a market for those who intend to call it home.
Marylebone and Mayfair Lead the Way
Location preferences have shifted considerably. While Kensington, Chelsea and South Kensington dominated in 2014, W1 postcodes now account for over a fifth of Black Brick’s transactions. Dell describes Mayfair as having undergone a “renaissance”, driven by public realm improvements and a transformation in perceptions of liveability.
Marylebone has been the standout performer, with prices in W1U rising 9.6% in 2025 — a remarkable result in an otherwise flat market.
What £1 Million Buys Today
Purchasing power in central London has eroded significantly. A £1 million budget now stretches to approximately 400 sq ft in Mayfair and under 500 sq ft in Knightsbridge — driving growing interest in prime outer London locations such as Wimbledon, Putney and Chiswick, where the same budget can deliver more than 1,000 sq ft.
