That is what happens polly, you never really see supermarkets, petrol stations, or utility companies undercut each other to any real degree, and all make massive profits, even the government body (eaga) set up to distribute central heating grants have a company, it was supposed to do 20% maximum of the grant work, they actually do around 40%, Iguana do 40% (came from nowhere to get that work), leaving 20% for any other heating companies, iguana and warmfront insist they are not linked, Mmmm!
