The UK’s super-prime property market currently has just 180 homes listed for sale above £15 million, representing 0.04% of all available housing stock in Britain, according to research from AgentWise.
The findings highlight the stark contrast between the ultra-high-end market and lower price brackets, where increased inventory has shifted conditions in favour of buyers. The limited supply at the top end has implications for how properties are marketed and sold in this segment.
Geographic concentration
London dominates the super-prime market, accounting for 81.9% of all homes listed between £5 million and £10 million, 83.1% of those between £10 million and £15 million, and 92.8% of properties currently for sale above £15 million.
Eric Corsaletti, founder of AgentWise, said: “As values increase, the market becomes dramatically smaller. There are tens of thousands of homes available between £1 million and £5 million, but once you move above £10 million there are only a few hundred properties across the whole of Britain.”
Private transactions
A significant proportion of transactions above £10 million are conducted privately through agent networks and do not appear on property portals, according to the research. This trend has increased the importance of agent collaboration and client relationships in the sector.
Corsaletti noted that buyers in this segment are typically international and often consider properties across multiple locations simultaneously. “A buyer considering a house in the South East may also be looking in London, the French Riviera or New York,” he said.
The research indicates that outside London, no individual agent or firm is likely to have access to more than a small proportion of the market, making inter-agency cooperation increasingly necessary. This contrasts with broader market trends, where recent data shows property sales rising 14.6% across other price brackets.
Market implications
The limited inventory at the highest price points means that traditional marketing approaches become less effective, according to AgentWise. The pool of potential buyers is smaller, more international, and often evaluating properties across multiple jurisdictions.
The concentration of super-prime stock in London and the prevalence of private transactions suggest that access to professional networks remains a determining factor in this market segment, where agent practices and transparency continue to evolve.
