With heating bills and global warming putting an increased emphasis on the energy use and environmental impact of homes, a new report has shown that it will take six-and-a-half decades to insulate every home in London if progress labours along at its present rate.
Historically conservatories have been seen as draughty and chilly – allowing precious heat energy to seep out of an otherwise well-insulated home.
Modern conservatories, glasshouses and lean-to glazed extensions on the other hand are much more environmentally-friendly (and stylish) than their antiquated counterparts.
London Assembly figures show that if all homes were properly insulated and had double glazing, carbon emissions in the capital would fall by a quarter (4.2 million tonnes).
Assembly environment committee chairman Darren Johnson, called for more to be done to insulate homes after it emerged that even basic insulation could save the average family between £250 and £350 per year on heating.
"Home insulation does not inspire photo shoots in glossy magazines like a new bathroom or kitchen – but those other home improvements will not save money or help cut carbon emissions like roof and wall insulation will," he said.
He also urged Boris Johnson to deliver 90,000 insulations per year to help the capital get up to speed.
Boris Johnson became mayor of London earlier this year after fending off Labours Ken Livingstone and the Liberal Democrats Brian Paddock – who recently appeared on Im A Celebrity, Get Me Out Of Here.
