October this year heralds the start of a possible game-changing Government initiative called the Green Deal. The Green Deal will open up the residential improvements market as never before by removing the need for householders to fund the cost of energy efficiency up front through the use of an innovative type of loan secured against the energy meter of a property, rather than the householders themselves, and is based on a principle known as the ‘Golden Rule’ that ensures the cost of financing the installed measures is less than the energy saved by their installation.
