I was sadly amused to hear about the promotion of Warmfront by the gov't the other day.
In theory they are supposed to be able to supply central heating installation, upgrades and replacement for the old and poor.
In practice there are so few approved contractors that they are able to ask for more that the allowance given by Warmfront. From the OAP's POV they are great value. However I feel that scheme is very wasteful.
I could go into details of how they operate... They are technically correct but have zero customer relation skills.
