Loft insulation/tank and pipes

As much as a quarter of your heating costs could be escaping through the roof without loft insulation.  Loft insulation is a very effective way to reduce heating bills.

Simply by insulating your loft to the recommended depth of 270mm, you can save wasted energy and money. If you currently have no insulation you could save between £285 - £395 a year on your fuel bills depending on your house type.

If your home has an accessible loft with no damp or condensation problems, it should be a good candidate for loft insulation.  Installers tend to use mineral wool insulation and laying this is usually straightforward for a professional.

For lofts with difficult access, a loose, fire-retardant insulation material can be blown into the loft using specialist equipment. This is a job for a professional installer and can take a few hours depending on the size of the loft.

You can even do it yourself!  Remember to wear a facemask, goggles and protective clothing if you do it yourself and leave sufficient gaps around the eaves to avoid condensation. DIY cost is approximately £100-£350 and payback time is 3 – 8 years.

Tank and Pipes insulation

Hot water tanks

Insulating hot water tanks and pipes will help keep your water hot for that nice long bath after a hard day's work.

Fitting a British Standard "jacket" to your hot water cylinder will cut heat loss by around 75% and save you around £80 a year for a DIY outlay of just £15. They can be found in any good DIY store and are cheap and easy to fit. If you already have a jacket fitted to your hot water cylinder, check that it's at least 75mm (3") thick. If not replace it with a new heat saving one!

Not all home insulation work has to be carried out by a professional. It may work out cheaper to do the smaller jobs yourself with materials from your local DIY store.

Pipe Insulation

It’s easy to keep your hot water hotter for longer. Simply fit foam tube insulation around your pipes, if they are easily accessible. These are available at your local DIY store for a cost of around £20 and will save you around £3 per year. If your pipes are hard to reach, you may need professional help.
