Where to Stay in London: Top 4 Sustainable 5-Star Hotels
There’s something magical about staying in London — its rich history, vibrant culture, and endless eateries. As a Londoner myself, I love playing tourist in my own city. For me, as someone who prioritises sustainable travel, finding a hotel that blends 5-star luxury and sustainability is the cherry on top.
After years of exploring this iconic city, and plenty of trial and error, I’m thrilled to share four 5-star hotels that not only offer exceptional service but also embrace sustainability. Here, luxury is redefined and elevated by responsibility, taking your experience to a whole new level.
Where to stay in London
Ham Yard Hotel
BEST TIME TO VISIT: A year-round gem, but personally, I adore it during Christmas season, May-July, or September.
LOCATION: In the heart of it all — just minutes from Soho and Piccadilly. Well-connected with Piccadilly Circus (Bakerloo & Piccadilly lines) and Oxford Circus (Central, Victoria & Bakerloo lines) just a short walk away. Covent Garden, Mayfair, and Regent Street are all within walking distance.
BOOKING.COM RATING: 9.4
MICHELIN GUIDE: 2 Michelin Keys, with an impressive rating of 19.5/20 (source).
WHY BOOK: It feels so exclusive and private, just 5-10 minutes from the buzz, but tucked away from the hustle. And with a bar, afternoon tea, bowling alley, and even a cinema — what’s not to love?
Kit Kemp’s interiors are, as ever, an uplifting mix of bold patterns, bright textiles, and upcycled curios. Sitting on the last corner of Soho that was bombed in the Blitz and never rebuilt, this hotel is so much more than a place to stay. It features a cinema, bowling alley, and a leafy, art-filled pedestrianised square. Plus, Ham Yard Hotel is known for its wonderful Afternoon Tea and a cosy rooftop terrace (open year-round!).
What makes it sustainable? As a new-build, Ham Yard Hotel is packed with top-tier insulation to boost energy efficiency. And with an Excellent rating from BREEAM — the leading global green building standard — it’s clear this hotel’s sustainability credentials are serious. The rooftop terrace is a true urban oasis, bringing biodiversity to central London with herb gardens, beehives, and an insect-friendly design that transforms the space into a little ecological haven.
Ham Yard Hotel - Rooftop Terrace
Perched on the fourth floor, Ham Yard Hotel’s rooftop terrace offers a peaceful retreat, featuring a seasonal vegetable garden and beehives tended by a dedicated beekeeper. With comfy seating and a bar, it's the perfect spot to relax, or even hire for private events.

1 Hotel Mayfair
BEST TIME TO VISIT: This is a year-round place to stay, but spring or summer is particularly lovely when you can fully enjoy the living walls and natural light.
LOCATION: Just a few minutes’ walk from Green Park Station (Jubilee, Piccadilly & Victoria lines), this Mayfair retreat is perfectly placed for both nature and city lovers. Hyde Park, Shepherd Market and the luxury boutiques of Knightsbridge are all within easy reach.
BOOKING.COM RATING: 9.0
MICHELIN GUIDE: 1 Michelin Key (source)
WHY BOOK: A sleek blend of organic luxury and greenery, all right in the heart of Mayfair. The perfect balance of style and serenity.
This addition to Mayfair sets a new standard for organic luxury. The sleek wood-and-stone furnishings of this biophilia-inspired retreat speak to the importance of honouring nature. From the living wall to the plant chandelier in the lobby and air-purifying planters in the rooms, the hotel is alive with greenery, including native moss species framing its signature water-filter dispenser.
What makes it sustainable? Adaptive design played a key role in its construction, with over 80% of the existing structure retained to minimise the environmental impact. Some flooring uses timber from the Windsor Estate, the Great Park’s commercial forestry offshoot. The emphasis on raw textures, living plants, and abundant natural light creates a calming, nature-focused sanctuary.
The One Aldwych
BEST TIME TO VISIT: YYear-round, but especially lovely if you’re catching a show in the West End.
LOCATION: A stone’s throw from Covent Garden and the West End - perfect for theatre lovers. Just a short walk from Covent Garden (Piccadilly line), Temple (Circle & District lines), and Holborn (Central & Piccadilly lines), offering easy access across London. The Thames, Somerset House, and bustling Seven Dials are all nearby.
BOOKING.COM RATING: 9.4
MICHELIN GUIDE: One Michelin Key with an impressive 19.1 out of 20 (source)
WHY BOOK: Ideal location, a chemical-free swimming pool for a real spa moment, snug rooms, and a refreshing selection of unique, thoughtful amenities.
Having opened back in 1998, One Aldwych still feels ahead of its time, effortlessly blending original features with modern sustainable design. A big shout-out to Javier, the Reception Manager, who was so welcoming, knowledgeable and genuinely passionate about the hotel.
What makes it sustainable? One Aldwych is a trailblazer in luxury sustainability, proudly holding a B Corp certification. It’s got some seriously clever innovations, like the water-saving EVAC loos, which use just one litre per flush instead of the usual seven. The spa and pool are a highlight too, with the pool’s chemical-free system powered by PoolSan’s ionisation technology, offering a cleaner, more sustainable swim experience.
The Mandarin Oriental
BEST TIME TO VISIT: Year-round is wonderful, but Hyde Park truly blossoms in spring, making it the perfect time to visit.
LOCATION: Right on Hyde Park’s doorstep, this iconic Knightsbridge spot offers the best of both worlds—green space and city buzz. Knightsbridge (Piccadilly line) and Hyde Park Corner (Piccadilly line) are just a short stroll away.
BOOKING.COM RATING: 9.0
MICHELIN GUIDE: 3 Michelin Keys and an impressive 18.5 rating out of 20 (source)
WHY BOOK: With stunning views of Hyde Park, this hotel strikes the perfect balance between timeless elegance and modern eco-conscious initiatives, offering a luxurious yet sustainable stay.
For me, the Mandarin Oriental holds a special, nostalgic place. During my time working in Hong Kong at a sustainable food and hospitality consultancy, we had the pleasure of collaborating with the Mandarin Oriental. It was incredible to witness the significant strides they’re making in sustainability, truly putting it at the heart of their ethos. And let's not forget — their food? Absolutely to die for!
This iconic property, overlooking Hyde Park, effortlessly blends timeless elegance with a modern, eco-conscious approach. It remains a favourite among discerning travellers who seek a luxurious yet responsible stay.
What makes it sustainable? The Mandarin Oriental’s commitment to sustainability is extensive, including energy efficiency, waste reduction, and water conservation initiatives. The hotel prioritises local sourcing and ethical partnerships, and has put a robust single-use plastic reduction strategy in place. So, while you indulge in the height of luxury, you can also be assured that your stay supports greener, more responsible practices.
Each of these hotels exemplifies how London’s luxury hospitality scene is shifting to prioritise sustainability. From Ham Yard Hotel’s rooftop biodiversity to 1 Hotel Mayfair’s adaptive design and One Aldwych’s chemical-free pool, these spaces are not just luxurious — they’re reimagining what it means to stay responsibly, yet stylishly.

Where in London is best to stay?
If you're wondering where the nicest area to stay in London is, it really depends on your preferences! For that classic London energy, Covent Garden and Soho are spot-on — bustling with shops, theatres, and an endless array of eateries. If you're after something a little more refined and laid-back, Mayfair by Green Park offers that luxe atmosphere, with quiet streets and high-end spots. For a creative, local yet central feel, Shoreditch is where it’s at — full of quirky cafes, fantastic restaurants, street art, and unique shops. Need easy transport links? King’s Cross is super convenient and has its own charm. And if peace and greenery are more your thing, Regent’s Park near Baker Street offers both. The park is stunning, and you’re close to Marylebone, which has a lovely village feel. Plus, Baker Street brings that iconic Sherlock Holmes charm, with easy access to Oxford Street and beyond.
How many days do you need in London?
I’d recommend at least 5 days to see the main sights and really soak up the energy, but honestly, with any city, you don’t want to rush it. Especially with London – it’s HUGE! If you want to explore properly, 6-10 days or more will give you time to dive deeper. And yes, London is super walkable – you can wander for hours, and I promise you’ll uncover plenty of hidden gems along the way!
Where to go from London for a Day Trip?
If you’re in London and looking for a day trip, the options are endless! Bath is just a short train ride away, and it’s all about stunning Georgian architecture and natural hot springs. Windsor is a must if you’re into royal history, with the iconic Windsor Castle at the heart of it all. For something more cultural, Oxford is a beautiful university town, perfect for wandering around historic colleges and charming streets. If you’re craving countryside vibes, the Cotswolds will win you over with its rolling hills, picturesque villages, and quaint stone cottages. And if a seaside escape is what you’re after, Brighton’s got that fun, quirky vibe with its shops and lively pier, while Margate is a hidden gem with an incredible arts scene and amazing food – an absolute haven for food lovers!
