"Berkeley Square, sustainability-led, the C-suite-with-an-ESG-mandate London base."
1 Hotel Mayfair opened in 2024 as the latest addition to the SH Hotels & Resorts 1-Hotel sustainability-led brand and the first 1-Hotel in Europe. The hotel sits on Berkeley Street between Berkeley Square and Piccadilly, a five-minute walk from Claridge's, three from the Ritz, two from the Wolseley restaurant. One hundred and eighty-one rooms, including fifty-two suites, across the converted-office-block tower, the upper tier with private balconies and Berkeley-Square-direction views. The hotel's operating model is the most-aggressive sustainability-positioning in London five-star, zero single-use plastic, sustainable wood and reclaimed-stone interiors, organic-cotton bedding, in-room water filtration. Dovetale, the in-house restaurant from two-Michelin-starred chef Tom Sellers, is the dinner room; the Dover Yard cocktail bar is the after-meeting space. 1 Hotel Mayfair is the right pick for the London business trip where the corporate-ESG mandate matters as a positioning signal, the financial-services or tech firm whose senior leadership has public sustainability commitments, the Northern-European-corporate visitor who expects sustainability infrastructure as table-stakes, and the multi-day Mayfair stay where the Berkeley-Square geography is the asset without the £900-a-night Claridge's tier. The hotel does not have the brand-recognition of the older Mayfair palaces, but the operating model is the most-distinctive new opening of the past two years.
Berkeley Square View Suite or 1 Mayfair Suite for the corner-tier upgrade.
Use the rooftop bar at 6pm for the after-meeting drink, the Berkeley-Square direction has the most-cinematic Mayfair view. Dover Yard 7pm for the business dinner; the chef's-table corner four-top is reservation-only. Walk to Claridge's for the Foyer afternoon tea, five minutes through Berkeley Square.
1 Hotel Mayfair sits within our broader Top 20 Hotels in London for Business list. It scored an aggregate 9.6/10 across the three editorial criteria, competitive against the field but, on business-specific factors, the angle above is what earned its rank. For the alternatives in the same London neighbourhood, see Mayfair, Berkeley Square and adjacent. For a different city entirely, see the related lists below.
If the dates are locked in, secure the room around the three-month mark. Suites with the prime view angle sell through first; for peak months, availability is measured in months rather than weeks. Suite-level rooms with private plunge pools or terraces, the ones that earn this rank, are typically the first to sell out.
A ranked shortlist, a special offer worth booking, and the overpriced stay to skip. Straight from the editors.
