A number of factors in your home can contribute to heat loss, meaning that you may be inadvertently wasting energy on a daily basis by not addressing some bad habits.

Here are just some of the most common areas which are responsible for heat loss, and the measures you can take to improve heat retention.


Poorly insulated areas in your home can contribute significantly to heat loss, with loft/roof space, uninsulated walls and uninsulated solid walls standing out as particular culprits.

Good insulation works to keep your house warm in the winter and cool in the summer, with the small air pockets - air being a poor heat conductor - inside the insulation reducing the amount of heat that can move from between the exterior and interior of your home.

As a result installing the right type of installation can help to maximise the gains from the heat in your home, and this can include roof insulation, cavity wall insulation and solid wall insulation (both internal and external).

The combined impact of these measures can stand to make you annual savings of up to £1,270 a year – with the average annual energy bill only coming it just above this level at £1,420.

However, it is important to note that all of these measures will involve an initial financial outlay.


Drafts can also be a contributing factor to heat loss, with ventilation and draughts making up to 20% of heat loss in an average home. While your home will need ventilation to ensure a supply of clean air, draft excluders can be used to reduce drafts in your home.

With windows and doors also contributing to up to 20% of heat loss in your home, you may also want to consider installing a door with a high-performance insulating material, as well as double-glazing, which can save homeowners as much as £170 a year.

Finding energy-efficient home heating oil could also help to minimise heat loss significantly.
