You can save even more money by making sure your home is as energy efficient as possible. Of course, one benefit of having a super energy efficient system is that less energy will be wasted too. You’ll be making the most of the energy that you’ve got and therefore getting better value, and needing less of it because little is wasted!
You can also consider draft proofing, cavity wall insulation and double glazing to help improve energy efficiency, and save even more money too.
