f you buy or rent a house ask to look at the Energy Performance Certificate (EPC) (which tells you how insulated and energy efficient your house is).
Things you can do to improve home insulation:
1. Look In Your Loft
For most homes, this can be a DIY job.
2. Check Your Walls
In most houses built between 1920 and 1980 the external walls are made in two layers, with a cavity in between.
Filling the gap is effective but expensive (around £500 for an average home)
3. Floors: Mind The Gaps
Lifting the floorboards and laying insulating material, supported by netting, between the joists.
Use a cheap tube sealant, such as silicon, you can fill any gaps between the floorboards and skirting boards to stop draughts.
Excluders on the bottoms of doors and across letterboxes.
