Savings calculator

Although energy saving bulbs initially look expensive to buy, once compared with a high energy alternative the savings are quickly evident! Energy costs are not coming down so let us help you keep your bills down and reduce your carbon footprint.

Each 50w halogen bulb you use costs you more than £10 a year compared to an LED alternative.

All energy saving bulbs will save you money, but working out exactly how much cash you will save can be difficult.

Our savings calculator will tell you exactly how much you will save each and every year when you buy an energy efficient light bulb.
