London homes are the least energy efficient in Britain according to a new survey commissioned by environmental charity Groundwork.
The Ipsos MORI survey asked 1,009 people in Britain about energy efficiency in their homes.
It found people in London had lower levels of cavity wall insulation, draught proofing and loft insulation than any other region.
The survey also found nearly a third of Londoners without cavity wall insulation or loft insulation would be more likely to invest in them if an expert could provide some personal advice.
Chief Executive of Groundwork, Tony Hawkhead, said: “What we need is a network of experienced advisors, skilled in providing support to communities, to help them navigate the red tape and paperwork.
“The recent freezing weather mean people’s fuel bills will be on the rise, for some to unmanageable levels, so it’s more important than ever to insulate our homes and save heat and money.”
