If you live in an older property, chances are there is something you can do to improve its energy efficiency. A home’s energy efficiency is defined as using less energy to perform the same task (i.e. heating and cooling.) This Top Ten Tips list has been created with Victorian through to early 1950s homes in mind. Cost estimations have been included, based on 3-4 bedroom semi-detached properties. However, many of these tips will also be of benefit to those living in properties constructed up until the early 2000s, before Part L of the Building Regulations – Conservation of Heat and Power – was first published.
