Homes priced above £15m account for just 0.04% of all residential property currently listed for sale across Great Britain according to new analysis from AgentWise.
The research highlights just how small and relationship-driven the super-prime property market becomes as values rise, with agents increasingly relying on private networks, cross-border relationships and collaboration to secure deals.
AgentWise found there are around 30,053 homes currently listed between £1m and £5m across Great Britain, representing roughly 6% of total market stock.
However, availability falls sharply at higher price points. Homes priced between £5m and £10m account for just 0.29% of listings, while properties between £10m and £15m make up 0.06%.
SUPER-PRIME
At the very top of the market, there are estimated to be only 180 homes currently for sale above £15m nationwide.
London continues to dominate Britain’s super-prime market, accounting for almost 93% of homes currently listed above £15m, alongside more than 83% of stock priced between £10m and £15m.
Even within the capital, however, supply remains extremely limited. Homes priced above £15m represent just 0.22% of all London listings.
Outside the capital, the South East is the only region with significant depth in the super-prime sector, accounting for around 9% of homes listed above £5m.
AgentWise says the figures demonstrate why collaboration between estate agents is becoming increasingly important in the upper tiers of the market, particularly as many ultra-high-net-worth buyers search internationally rather than within a single region.
DISCREET NETWORKS
Eric Corsaletti, Founder of AgentWise, says: “As values increase, the market becomes dramatically smaller. There are tens of thousands of homes available between £1m and £5m, but once you move above £10m there are only a few hundred properties across the whole of Great Britain.
“At that level, the traditional process becomes far less effective. The pool of potential buyers is smaller, more international, and often looking across multiple locations at the same time.
“It is also important to remember that many of the highest value transactions never reach the portals at all. Particularly above £10m, a significant proportion of deals are carried out privately through trusted agent relationships and discreet networks.”
