Cavity wall insulation is something which most people have not done, but if you’re one of the few people who’ve yet to do it themselves then you should seriously consider looking into whether or not your home has that option. It is typically a pretty cheap and fast option and compared to most other energy saving options, it is very cost effective.
Most energy saving plans involve a measurement of how quickly you can make your investment back in savings, and cavity wall insulation ranks as one of the best. Another one worth looking at is loft insulation, which is an even better investment. There are also calculators available online which will show exactly how much money you could expect to save on a yearly basis.
Another important thing to note is how much value this can add to your property. For a small investment of just a few thousand, you can also increase the value of your home by an equivalent amount.
