The Green Deal aims to improve the energy-efficiency of homes and businesses by allowing energy improvements to be installed at no upfront cost. Instead, you pay for the improvements over time through your electricity bill. The repayments cannot exceed the amount you are expected to save on energy costs, so there should be no increase in your bills as a result of taking out a Green Deal Plan.
A Green Deal Plan is linked to the property, not to any individual: if you move out, the next bill-payer will become responsible for the repayments. This means that you can safely make improvements without tying yourself to the property.
All properties are eligible for the Green Deal, regardless of whether they are owned or rented. And credit check thresholds are expected to be much lower than average for Green Deal finance (source: Green Deal Finance Company), meaning that the Green Deal should be accessible to most.
