Incredibly simple, man has cut his lighting bill from 133 to 14 pounds a year

There is no doubt that we are always looking for ways to save some money.

So it might be a shock to find out that there is something really simple to massively reduce your energy bill.

Retired electrical engineer Rodney Birks has revealed his simple trick to lower the lighting costs in his home - and you want to be stupid when you realize what a big difference a small change can actually make.

All you need to do is change your bulbs (picture in stock).

The 72-year-old from Swindon betrayed The Guardian at the weekend his "hack".

Rodney, who has spent his life developing tools for automobiles, adds, "Converting your fridge or freezer into an A +++ appliance is likely to add 20% energy efficiency.

"But if you change your lighting, the new LEDs are ten times more efficient than the bulbs they replace, and there's nothing like that in terms of electrical efficiency."

According to, LEDs last up to 50 times longer than incandescent bulbs and provide up to 50,000 hours of illumination.
