Heidi Ondrak, 51, has seen her direct debits for gas and electric hike from £98-a-month to £268 - a 173 percent rise - and is dreading another increase in October this year. The mum-of-two is finding as many ways as she can to cut down on her bills and save energy. She has taken to showering at her local gym to save on her water bill, and limits showers to four minutes if using the one in her home in Plymouth, Devon. She saves £28-a-month on meals by switching off her oven and hob and instead using an air fryer, slow cooker or George Foreman grill to make her family dinners. Now Heidi has decided to light her home with cheap solar panelled garden lights which she charges at her window during the day, so that she can keep her house lit for free. Heidi, a project manager, said: “I try to do as much as I can to save where I can. “I had the idea to buy some garden solar lights in the sale and can charge them up all day on the window and then use them in the evening so we’re not using electricity by having the lights on.
