Over half the warmth lost from most homes is lost through the walls and roof. Insulation can substantially reduce this heat loss enabling you to keep warm for less money. When your home is insulated your boiler, or other heating source, will not have to work so hard to provide you with the warmth you need, and it will not take so long for your home to warm up after the heating is switched on. You can adjust your timer to switch the heating on later than before - saving energy every day.
Cavity wall insulation can save you about £140 a year on your energy bills.
Loft insulation can save you up to £180 a year on your energy bills.

Lofts can be insulated in just a few hours and with minimum disruption to you, provided you have good loft access and the loft area is clear.
If you do not have good loft access we may be able to help: we can increase the size of the existing loft hatch if this is necessary, and even create a new loft hatch if you don't have one.
We install loft insulation to Building Regulations requirements, which is 270mm (about 10½ inches). If you already have insulation, perhaps installed ten or twenty years ago, it may be less than this, in which case we can ‘top-up’ to 270mm.
In any event it is worth getting a surveyor around to check what insulation you have and what extra could usefully be installed.
Cavity Wall Insulation
Most cavity walls can be filled at very low cost or even free of charge and the work can be completed in half a day. We offer a variety of materials, including bead and fibre.
We drill holes in the wall at regular intervals in order to ensure walls are fully insulated. We always drill in the gaps between bricks and plug the holes afterwards – it is very hard to see evidence of where the drill had been, especially after a few months of weathering. The same applies to homes that are rendered, where we make every effort to match the colour of your walls.
Whatever wall insulation material we install, it is covered by a 25-year guarantee by CIGA (the Cavity Insulation Guarantee Agency).
If you have been turned down for cavity wall insulation in the past we encourage you to contact us. New materials mean we can now insulate 'hard-to-treat' cavities that could not have been filled just a few years ago.
Solid or Cavity Wall?
As a rough guide, most homes built after about 1930 are of cavity wall construction and most homes built before that are of solid wall construction.
It is important to know what type of walls you have, as cavity walls can be insulated in less than a day at low cost (or even free of charge), whereas solid walls require special insulation that takes a week or more to install and is costly, running into many thousands of £’s.
If you are not sure contact us and we can arrange a home survey.
Blocks of flats have often been left 'out in the cold' in the past, but we can insulate your block, and it might not cost you a penny!Read More
