The government's digital service DirectGov has urged consumers to switch energy tactics if they want to save money on their bills.
Householders were advised to abandon traditional light bulbs for more efficient energy-saving light bulbs because they are better at converting electricity to light and use less power.
Low-energy light bulbs such as Compact Fluorescent Lamps (CFLs), for example, last up to ten times longer and use less energy than incandescent bulbs.
Just one energy-saving bulb costing around £2 could save between £3 and £6 in a year, DirectGov said.
In order to generate light efficiently, low-energy bulbs typically contain 4mg of mercury, which can be harmful so in the event of a breakage, householders are advised to leave the room for at least 15 to 30 minutes, ensuring the room is well ventilated.
Rubber gloves should also be used to clear up debris, while the area where the breakage occurred should be cleaned with a damp cloth.
Recent studies from the Grantham Institute for Climate Change at Imperial College have found that installing energy-efficient light bulbs could reduce the UK's carbon emissions by up to 40 megatonnes a year.
