Business electricity supplier British Gas has been urged to set a good example for its customers by improving the energy efficiency of its own premises.
An investigation by the Daily Mirror using thermal imaging cameras revealed the supplier's head offices in Slough often has lights and heating on, even during periods when very few staff are in the building.
Centrica, the owner of British Gas, responded by observing that over the past five years, energy consumption in its buildings has been cut by 21 per cent due to features such as motion-sensitive lighting, while it is investing millions of pounds in boosting its green credentials.
Like the other Big Six suppliers, British Gas also offers schemes to help customers improve their energy efficiency, such as providing free and subsidised insulation measures.
Recently, an investigation by independent price comparison site EnergyHelpline.com revealed many government departments may also be spending more on energy than necessary, with the Home Office's gas and electricity bill for their London headquarters coming to over £1 million per year.
