How do I know that the green deal will save me money?

Properties will be rigorously evaluated by accredited Green Deal accessors before any Green Deal funding can be allocated. This ensures that ONLY properties which will benefit financially from Green Deal will be allowed to participate. This protects the property owner and ensures that cost of any improvement will be covered by the savings that the improvement will make to the energy bill.  However, the government are keen to point out that there is no way to predict the future cost of energy bills and all calculations will be based on current prices.
