It comes the week before parliamentary discussion of legislation to help insulate the nation’s homes begins.
Friends of the Earth is warning the Government’s current proposal will do little to keep vulnerable tenants warm without a tough new law to stop landlords letting the coldest properties until they’re improved.
Properties rented from a landlord or letting agency are most likely to be the worst insulated and a recent Friends of the Earth survey found half of these tenants were uncomfortably cold in their homes during the big freeze.
Natasha Khan, of Bat for Lashes, said:
"We suffered the worst mould you could imagine in my student house.
"Over our two-year let it got to the point where you’d have to dodge at least 20 slugs living off the moisture in the carpet – then inhale black mould spores if the steam from the shower got too much.
"The cold, draughts and dampness were pretty extreme!
"Everyone should get behind Friends of the Earth’s campaign to protect tenants in cold houses – it’s time to heat our homes, not the planet."
Friends of the Earth’s Warm Homes Campaigner Dave Timms said:
"No-one should have to put up with renting a cold, damp home that makes them ill and costs a fortune to heat – £1 in every £4 we spend heating our homes is wasted because of shoddy insulation.
"Stopping British houses leaking heat is one of the cheapest and quickest ways to fight dangerous climate change.
"We need a new law making it illegal to let the coldest, health-hazard properties until they’re improved to a minimum energy efficiency standard – and greater support for landlords.
"Tell your MP what it’s really like living in a cold home at www.coldtimes.co.uk to join the fight for warmer homes and a safer climate."
