This is all true, Pugwash. But I still feel it is up to the buyer to make their choices, don't you? Being a member of LAS2000 helps with ensuring the bills are fair and reasonable. And when paying the price for new and VERY good new double glazed windows, the council give people three years no interest credit. Still, it's a lot of money but when doing the search you should find out if anything is planned in advance by about five years, like new windows for example!
