a bloke from www.markgroup.co.uk came to our door today and tried to sell us Cavity Wall Insulation (at a reduced rate through the government scheme). I know very little about Cavity Wall Insulation but i know it improves overall heating costs/carbon footprint etc etc
My (semi det) house was built circa 1990 and is not really a cold house, always warm. So can anyone suggest if its worth getting installed or not? He obviously knows his stuff and was desperate for me to accept it but i need to know more first. I thought it was good for older properties etc?
He's quoted us around £100 (after the governments part payment)
Thanks
Mike
