House that produces so much electricity the National Grid pays the owners! Couple receive £1,500 cheque after creating eco-property with two types of solar panels
As winter bites, many of us worry about the thud of a hefty heating bill on the doormat. But not Tim Willcox and his wife Margaret, who instead look forward to receiving a cheque from the National Grid paying them almost £1,500. The couple have built an eco home that is effectively a miniature power station, exporting their home-grown electricity. The impressive property (right), which cost £500,000 to build in Chilcompton, Somerset, includes solar panels that generate electricity, super-insulated walls and a rainwater harvesting system. Its interior, pictured (left), is stunning and includes all the modern features you would expect from a fully functioning property.
