Using energy efficiently within the home is aimed at achieving the required level of comfort, at the least cost to the householder, while minimising damage to the environment.

Whilst the use of energy within the home is an essential part of daily life, nevertheless, an excessive amount of energy is wasted or lost within many or our dwellings. (source: Energy Action Ltd.)
