Insulating Your Home Properly

Most people assume that the cost of insulating their homes is a great deal more than it actually is. New materials, government initiatives, climate change, home information packs and rising energy prices, prove that there has never been a better time to insulate your home.

The money that you spend in some areas could be repaid in less than 12 months. An insulated home will also produce fewer carbon emissions and you will be playing a part in fighting climate change. Remember, all the savings you make will happen year after year after year…

We have highlighted below many of the ways that you could insulate your home. Costs, savings potential and payback times will vary depending on each job.

What is certain is that each measure will save you a significant amount of money on your heating bills and reduce your carbon dioxide emissions.

loft insulation

Loft insulation is an easy way to save energy in the home. You can install yourself, and save around £110 year on year. It could pay for itself in less than 3 years.

hot water tank & pipe insulation

Good insulation will keep the water in your pipes and tank hotter and for longer. Fit this yourself and save around £30 per year on your heating bills.


Relatively affordable and extremely effective, draught-proofing is a great energy-saving measure for the home – yet it is often overlooked. Eliminate draughts and stop heat escaping through those gaps by fitting low cost, easy-to-fix brushes and seals. You could save around £20 and 155kg of carbon dioxide per year.

New Windows and doors

Investing in good quality windows and doors is a great way to help your home become more energy-efficient. If you decide to update your windows or doors that you choose the right style for your home, for example, double glazed bifolding doors or French doors add a more elegant yet energy-saving look to the home.

Double glazing can prevent heat loss through windows by 50%, saving you around £100 per year.

If you are on a budget there are ‘other ways’ to prevent heat from escaping out through your windows,  although double glazing is highly recommended, not only for energy-efficiency but to improve security.

cavity wall insulation

If your house was built after the 1920s the external walls would probably be made of two layers of brick with a small air gap or cavity between them. If you insulated your wall cavities you could save around £90 on your heating bills and 750kg carbon dioxide per year.

solid wall insulation

If you live in a home with solid walls (non-cavity walls) such as solid brick, solid stone, pre 1944 timber frame and non-traditional i.e. concrete construction approximately 45% of the money you spend on heating is escaping out through the walls. Solid wall insulation is not cheap but the savings both financially and environmentally are huge!

floor insulation

Gaps and draughts from skirting boards and floorboards are easy enough to fix yourself with a tube of sealant. Timber floors can also be insulated by lifting the floorboards and laying an insulating material between the joists. Save around £60 and 470kg carbon dioxide per year.
