When you think of green accommodation, chances are you don't think of budget hotels. But tomorrow, Premier Inn will be opening Britain's greenest hotel in Tamworth, Staffordshire (premierinn.com). Endorsed by the Carbon Trust, it combines green building materials and an array of ground-breaking technologies unmatched anywhere in Britain. The 20-room hotel will have the same facilities and amenities as a standard Premier Inn, but will use much less energy, thanks to features including: ground-source heat pumps that use the earth's natural energy to cool and heat rooms; solar panels that heat bath water; and low-energy lighting with motion sensors which ensure that lights remain on only when they are needed. Double rooms start at £53.
