Energy saving light bulb

Energy suppliers have been banned from sending energy saving bulbs to customers

Energy saving light bulbs have been by far the most popular method of energy saving among people in the past twelve months, according to new research by Which?.

The survey of more than 2,000 people found that just over three quarters had installed energy-saving light bulbs in the past year, with the next most popular measure, loft insulation, adopted by just one third of people. A quarter had double glazing put into their homes, while only a handful had solid wall insulation or floor insulation put in.

People don't trust energy companies

The Which? survey also found a general lack of trust for energy companies. Only around a quarter said they trusted their energy supplier to sell them the right tariff to suit their needs, while less than a fifth felt that energy companies try to keep tariffs at a reasonable level.

Only around one in 10 believe that energy companies treat their customers fairly, or are open and honest about the costs that make up their bills. Our energy satisfaction survey  shows you the best and worst energy companies, according to the experiences of Which? members.

Save money with energy saving tips

The most common things people believed they could do to save energy in the home was to turn off appliances and lights when they were not being used, but almost nine in ten felt they were confident they knew what to do to make their home energy efficient.

But while three quarters think they're doing their bit for energy efficiency, four in ten think it's too expensive to make their home energy efficient. In general, the majority of consumers we surveyed are worried about the cost of energy bills.
