Flemings Mayfair has reached its 175th anniversary, and the Half Moon Street hotel is marking it with a limited-edition package running from 1 September 2026 to 31 January 2027. The 129-room property has been family-owned and independent since Robert Fleming opened it in 1851, which makes it one of a shrinking number of central London hotels still trading privately from the same address.
For business travellers, the practical detail is the offer itself. The anniversary package covers a two-night stay, daily continental buffet breakfast for two and a £175 Selfridges gift card, subject to availability, and it is bookable across all room types. For every booking taken, £1.75 is donated to CEO Sleepout, a long-standing charity partner of the hotel that raises funds to tackle poverty and housing insecurity in the capital. Two-night minimums suit the midweek pattern most corporate trips to the West End follow, and the Green Park and Piccadilly walk-in radius puts client offices across Mayfair and St James’s within a few minutes on foot.
A Mayfair address with literary form
Fleming had worked in private service as valet to the Marquis of Anglesey, and used his savings and that experience to acquire No. 10 Half Moon Street. The hotel opened in the year of the Great Exhibition, when more than six million visitors came to London. By 1855 Fleming and his wife Mary had expanded into Nos. 9 and 10, running a “Private Hotel” for London’s aristocracy and gentry, with personal service as the selling point.
The street itself has a long literary record. James Boswell lived there in 1768, followed by William Hazlitt, Frances Burney, Henry James and Wilfred Owen. It appears in Oscar Wilde’s The Importance of Being Earnest as the location of Algernon Moncrieff’s apartment, and the address has been linked to Agatha Christie’s At Bertram’s Hotel, with Flemings among the Mayfair hotels thought to have inspired the fictional setting.
That history is worked into the current product rather than left in a brochure. The three-bedroom suite, redesigned in 2025 by Tully Filmer, takes its cue from the Wilde play, and guests are left a copy of it at turndown. Manetta’s Bar draws on 1930s Mayfair, and the hotel’s private art collection was developed with the photographer Andy Gotts MBE.
What the Flemings Mayfair 175th anniversary means for corporate bookers
The hotel holds a Michelin Key, awarded to a small group of properties recognised for an exceptional stay, and it houses the Michelin-starred Ormer Mayfair alongside The Drawing Room. For anyone hosting a client dinner between meetings, that removes the need to book a restaurant elsewhere and manage a cross-town taxi at the end of the day.
It also lands in a competitive stretch of postcode. Mayfair has seen a run of upgrades aimed squarely at senior business travellers, from new top-floor suites at the Athenaeum to the Paul Smith Grand Suite at Brown’s Hotel, with the St Regis London opening nearby. Most of that investment sits inside large international groups, which is what makes a 175-year-old independent operator on the same street worth noting when bookers are comparing rates and consistency.
Independence as the pitch
Ownership is the point the hotel keeps returning to. “175 years is a long time, and a lot has changed around us,” said Henrik Muehle, Managing Director of Flemings Mayfair. “We’ve changed with it, of course, but we’ve always remained family-owned and independent. I think that’s what makes Flemings different. We can do things our own way, make decisions quickly and keep the character of the hotel. That’s something we’re very proud of.”
In practice, that speed of decision-making is what travel managers tend to test when a flight slips, a meeting overruns or a late checkout is needed at short notice. A single-property owner can answer that without escalating to a regional office, which is the argument independents have made for years and the one Flemings is making on its 175th birthday.
