Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate he has made of the average savings accrued to households of using LED instead of conventional lightbulbs.

Each LED bulb will save a household around £55 over its 15 year lifetime. This consists of £43 in reduced energy consumption and £12 in reduced replacement costs (given LED bulbs last around 7.5 times longer than traditional halogen bulbs). Our analysis suggests that there are approximately 35 bulbs in an average household, so savings will be around £125 per year.
