In the bustling theatre district, One Aldwych is London's most eco-friendly hotel. Having won several awards for sustainability, the hotel prides itself on green practices including recycling, LED lighting, biodegradable packaging and water-reduction systems. Wander around the Edwardian building to admire more than 300 works of contemporary art, or head to Indigo restaurant for dairy- and gluten-free modern British cuisine made with seasonal ingredients sourced from the British Isles.

Showcasing the same sense of creativity as its namesake (the founder of Notting Hill Carnival, Rhaune Laslett), this hotel pairs quirky antiques and avant-garde artwork with muted colours and soothing tones. Peruse the stalls of Portobello Road Market and check out Notting Hill's impressive café scene before returning to The Laslett for the evening. An ode to its location, The Henderson restaurant uses produce that is locally sourced, seasonal and organic. Dinner demolished, round off the evening with the hotel's signature rum-laced cocktail.

Despite being a picture of Victorian elegance, this classic white-stucco terrace house has a shockingly modern outlook. A tranquil haven in the Big Smoke, it is adorned with contemporary art and eclectic furnishings from across the globe, while a tree-filled private garden helps to offset the hotel's carbon footprint. Rooms, some benefitting from private outdoor spaces, are decorated with bold colours and rich woods and have granite bathrooms kitted out with sustainable toiletries from local London brand Miller Harris.

Founded on the idea that a hotel escape should be filled with as much adventure, excitement and imagination as a child's treehouse, Treehouse London is designed with nostalgia in mind. Pared-back rooms feature exposed-concrete walls and ceilings, while charming touches such as soft toys perch on beds. Reclaimed-wood furnishings give the hotel an outdoorsy atmosphere, while it also runs eco-conscious composting and recycling programmes, has reduced single-use plastics and uses organic cottons and locally sourced toiletries.

Perched along a tree-lined street, this London townhouse pairs sophisticated interiors with a sustainable ethos - it has a great recycling scheme and uses environmentally sound products. Spend days gazing at art-lined walls of the drawing room or cuddling up with a book in the hotel's library before heading out to explore Knightsbridge, where you'll be spoiled for choice with dining and drinking options.

Dreamed up by actress Anouska Hempel, Blakes Hotel's boutique style and decadent touches ooze nothing but class and sophistication. Spend mornings sipping coffee amid the colourful foliage, patterned cushions and Moroccan-tiled floors of the Matthew Williamson-designed garden, and afternoons dining on Mediterranean dishes in the sleek restaurant. Cutting down on water and chemical waste, the hotel only offers towel- and sheet-washing services on request.

This boutique hotel sits pretty in historical Clerkenwell. A converted 19th-century warehouse, the it pairs original features with stylish, contemporary design and eco-friendly tech galore. Sustainable systems are rife in the hotel: water is pumped from a 1500ft borehole which means that the building is self sustaining, while an energy loop system simultaneously heats rooms and cools down refrigerators. There's an energy-saving occupancy detection system installed bedrooms, too, and all timber and paints are environmentally friendly. If that isn't enough, the hotel's restaurant only uses seasonal ingredients sourced from local suppliers - cosy up with a cocktail amid retro lamps and velvet-upholstered chairs to feast on plates of classic British dishes (be sure to try the charcuterie and cheese boards, served with homemade crackers and seasonal chutney).

This eclectic boutique hotel pairs quirky design with a strong eco-conscious disposition. Artist Residence London prides itself on recycling waste as well as using energy-saving light bulbs and eco-friendly cleaning products. Reclaimed and salvaged materials are used throughout the hotel's interiors, from the wooden furnishings in the lounge to the wood-lined en suites and four-poster beds in hotel bedrooms. Dine on reclaimed-wood tables in the Cambridge Street restaurant among artwork supplied by local art gallery Lawrence Alkin before heading upstairs to soak in the bath with natural Bramley bath products.
