Loft insulation is by far the best and most effective way to improve the warmth of your home whilst reducing energy bills. Up to 30% of all heat lost is through the roof and considering a typical installation will be in the region of £400 for a medium sized home, it doesn’t take a lot of thinking to see this pays back almost straight away. The payback is never more than two years.
Loft insulation should be at least 25cm in depth but the thicker the better. Typically a home should have 50cm of insulation. The cost upfront is repaid so quickly cutting corners makes no sense at all.
Reliable installers can be found easily all over the country through government initiatives meaning the installation itself might even be free up to 50cm in depth. The latest information is that any depth beyond 50 cm will not qualify for further free insulation however I would strongly advise going through Government channels in order that you can gain access to skilled tradesmen that are well vetted for the installation.
Installation is pretty straight forward, large rolls of insulation are laid out between eaves, they are then cut and fitted nicely into all corners and gaps. Sometimes, once eaves are filled with insulation a second layer can be placed directly on top to double up and ensure little to no heat loss through your roof. Keep in mind that after 50cm the government will no longer need to assist you with costs as this is the point best value for energy saving ceases to be viable. It’s here that we might consider other options for energy saving that the government is pushing such as solar, and the attempt to make solar financially viable.
Currently all homes are entitled to some sort of funding, the level depends upon income and size of home. Larger homes tending to gain additional funding. CERO was setup in an attempt to help all homes with cavity wall insulation and well as lofts that require insulation.
Many homes can qualify based on postcode as well as carbon reduction policies. It is worth checking with your local council as the schemes are different with each different council. There is no better way to save energy and money so if you want to go green, get the loft done first. Once the loft is done the next place to start looking for improvements will be cavity wall insulation and sash window draught proofing.
