Companies are being invited to submit proposals to help a selection of government departments in Whitehall tackle prices from energy suppliers and reduce their emissions.
The Energy Efficient Whitehall competition is inviting suggestions from businesses for retrofitting ideas or technology plans that could help offices such as the Department of Energy and Climate Change and the Foreign and Commonwealth Office switch energy practices.
A budget of £2.5 million will initially be made available to fund the winning proposal and this figure could rise if the scheme proves a success in the first few departments.
Iain Gray, chief executive of the Technology Strategy Board, the organisation running the competition, said: "This retrofitting solution will provide the building blocks needed to engender a dramatic improvement in the energy efficiency of government buildings."
Entries will be accepted until the third week of February next year and the winning scheme could be initiated in the autumn.
Better insulation and the use of energy-saving light bulbs can both help reduce business energy costs.
