With good loft insulation, homeowners can save up to £590 every year. Cavity wall insulation can cut
heating costs
by about £285 each year. Solid wall insulation can bring yearly savings of up to £375. These savings
come from
better heat retention and less transfer of heat in the home.
It’s important to know that real savings might change. They depend on things like the size of the
property, how
people use energy, and energy prices. The Energy Saving Trust says that a home with full insulation
can cut its
energy use by as much as 45%.
