cavity wall insulation... too many scare stories floating around
Is this too good to be true?
There are catches, however. British Gas has around five million dual fuel customers and a limited stock of 200,000 installations available so anyone interested should register on its website as soon as possible, even though the deadline is 31 May.
Plus, it is only free for those with less than 60mm of insulation already while the size of their loft must be 80m2 or under. The cavity wall is also only free up to 140m2.
Homes with a loft space bigger than 80m2 or walls bigger than 140m2 still won't pay for the free components but they will be charged a top up fee of £5 per square meter to get the rest of the home insulated.The deal also excludes any scaffolding or specialist equipment that may be necessary.
Until Sunday 10 July
