The Leconfield: London’s Ultra-Exclusive Members’ Club Backed by Liz Truss

The Leconfield is a proposed ultra-exclusive Mayfair members’ club backed by former prime minister Liz Truss and aimed at global power players.

With a £500,000 membership fee and the promise of access to a primed global billionaire network, the club’s founders will hope its fortunes will last longer than the prime minister who backed it – one that was outlasted by a lettuce.

In London, it may feel like private members’ clubs are opening with the regularity of a new chain coffee shop.

But there is a potential new kid on the capital’s leafy blocks that is shunning the step and repeat model of its contemporaries and offering a truly ultra-exclusive membership experience to the highest echelons of the international business world.

It therefore feels fitting, The Leconfield in Mayfair, will be headed by a former British prime minister and carry an eye-watering once-in-a-lifetime £500,000 membership fee and an AI-powered networking system.

The minds behind the venture have made their pitch clear: The Leconfield is an arena for serious arena for billion-pound deals and world-shaping decisions, rather than for “copious bouts of drinking and salacious excess, all firmly encouraged to climb the slippery rungs of London’s social ladder”.

A forum for global power players

The vision comes from Iranian-born British entrepreneur and Reform UK donor Robert Tchenguiz, who has owned Leconfield House since the late 1990s.

The target membership reads like a Who’s Who of global power players: FTSE 100 and Fortune 500 executives, tech founders, ultra-wealthy individuals, and private equity partners

Whether The Leconfield can deliver on its audacious promises remains to be seen. London’s private members’ club scene has evolved considerably in recent years, with venues like Apollo’s Muse charging £5,000 annually and Maison Estelle operating with near-total discretion for the 0.01%. Yet even in this rarefied company, a £500,000 entry fee represents a quantum leap in exclusivity

The numbers behind The Leconfield are staggering, even by London’s club scene’s rarified standards. The project seeks 700 founding members, each committing half a million pounds for a lifetime membership structured as a debenture that can be inherited or sold.

Do the maths and you’re looking at £350 million in total capital – £200 million of which will settle the building’s mortgage, with the remaining £150 million earmarked for an extensive renovation of the former MI5 headquarters.

Prime investment from a former Prem

Truss herself has taken a hands-on, paid role in the venture, personally managing the membership list and facilitating introductions between prospective members.

When questioned about her involvement, she described herself as “a commercial person,” leaving little doubt that this isn’t a philanthropic endeavour.

Her involvement represents a marked pivot from Westminster to the world of high-stakes private enterprise – a trajectory that’s raised more than a few eyebrows given that her 49-day premiership ended in economic turmoil just over two years ago, and outlasted by a lettuce.

Theatrics and tech collide

The membership recruitment strategy borders on the theatrical. Billionaires, diplomats and royalty have been receiving bespoke black lacquered boxes containing tablets that play Truss’s pitch video.

It’s a far cry from the standard email campaigns most clubs employ, signalling from the outset that The Leconfield aims to occupy a different stratosphere of exclusivity.

The club’s technological ambitions seem equally bold. AI will track members’ movements within the building and recommend through an app which members should connect and what business opportunities they might explore together.

Future currencies: Betting on success

The project’s success will likely depend on whether Truss and Tchenguiz can assemble a membership roster impressive enough to justify the astronomical price tag.

In a city where connection and access remain the ultimate currencies, The Leconfield is betting that there are at least 700 people willing to pay handsomely for a seat at what it promises will be the most influential table in town.
