Richmond Hill Hotel
Nestled atop a hill in London's greenest borough, Richmond Hill Hotel is committed to a greener future. Since 2015, they have been on a mission to minimise their environmental footprint. This has included: achieving a carbon-neutral status from Carbon Neutral Britain; using only Renewable Energy to cover all of their electricity needs; and investing £9 million in technology across the hotel to reduce emissions. They clear waste responsibly with none heading to landfill; encourage green travel and invested in EV chargers for electric car-driving guests; and have worked with some fantastic partners to deliver training for their staff with a particular focus on diversity and inclusion in the last 12 months. Looking ahead, they are shooting for the stars and looking to achieve net-zero emissions by 2040. Sustainability is more than just a buzzword for them, as London’s gateway to nature, they are truly committed to a greener future. For delegates looking to make a greener impact, why not take part in a river clean-up by paddleboard? This team activity is available to book at Richmond Hill Hotel.
Eton College, Dorney Lake
Best known as the 2012 Olympic and Paralympic rowing venue, Dorney Lake is actively managed with biodiversity in mind. Changes to mowing practices across the site have allowed wildflower species to grow more naturally, including self-seeded orchids, helping to support richer habitats across the parkland. The wider site spans 400 acres and includes an arboretum with a diverse range of tree species, as well as a designated conservation area for birdlife. These features are part of the wider story of Dorney Lake: a venue shaped by sport, landscape and careful stewardship. For corporate events, that creates a stronger sense of place and a more meaningful connection between delegates and their surroundings. For businesses planning conferences, leadership meetings, away days or team-building events, Dorney Lake offers much more than a functional event space. It gives delegates room to think, connect and reset, while spending time in a landscape that continues to support nature and biodiversity.
