OK. this one maybe a bit hit and miss as it will only benefit a few people (so dont slate it to much!)
Powergen are offering customers in certain areas their Central Heating Care 50 Package free when they move house. If you move home to a house that doesnt have the gas supplied by them and agree to have them supply it then as a sweetner they will throw in the package for free for a year if you tell them you have heard about it. The normal price is £9 a month or £108 a year.
Its a fairly good package and its a bonus if you can get it for free as it gets you an inspection of your boiler and stuff when you first take it out.
like I said though, not everyone will be able to get it but those who can may as well get the most from them.
the link is to their site so you can see if it covers your area but like i said you can only get it if you are moving and you call their house moves department.
Slate Away peeps.
