The loan would be linked to your property, rather than to you, and is designed to help spread the cost of energy saving improvements by allowing households to pay back the loan from the energy savings made each year.

The ‘save-as-you-pay’ initiative is part of the Governments plan to cut emissions from all 22 million UK households by 29% by 2020.

Installing solar panels can reduce energy bills by up to 80%, and can even earn money from selling energy back to the grid. But many are unable to fund the initial cost of installing such measures, which can amount to around £7000-£10,000.

Whilst this new scheme would help to reduce this initial investment, critics argue that new home owners could be forced to pay for the previous owners loans, and could lead to problems selling a home in the first place.

“I think it could have a detrimental effect on the housing market. Just the principle of attaching a loan to the property complicates things unnecessarily and it interferes with the free market value of the house,”  Gary Smith, President of the National Association of Estate Agents says.

However, Ed Miliband argues that the improvements made to the home, and therefore the energy savings, would far outweigh any loan attached to the property:  “You’ll find that the energy bills are significantly lower so, say, you’ll be having a few hundred pounds off your energy bills and offsetting that you’ll have a couple of hundred pounds in payments.”

The Conservatives argue that any loan paypack should be linked to household energy bill, allowing greater transparency: “It would not be a debt attached to the home, we would pay it off over time through the electricity bill,” Greg Clark, the Conservatives energy spokesman.

The Goverment is due to launch a new Feed in Tariff for solar panels and wind turbines in April, allowing homes to sell energy back to the grid in return for tax-free cash. This is coupled with existing grants available towards the cost of cavity wall and loft insulation.

Whatever your view, it seems evironmental policy, and specifically how to encourage households to cut emmissions, will be a popular point of discussion in the run up to this year’s general election.

It says that 3.6 million homes are entitled to loft or wall insulation, which could save £150 off their annual energy bill, but so far only a fraction of the amount available has been claimed for.

Free insulation grants are available for cavity wall and loft insulation, preventing around 40% of heat from an average home escaping through walls and lofts.

Huge savings can be made by those households who take advantage of the insulation grants. And it is not just available for households on low incomes or the elderly – anyone can claim a grant of up to 50% of the cost of insulation.
