I think if it was carried out by a sub contractor, they have to supply a 5-6 year warranty on shoddy work, the 2 years is for defective parts. I know my old boss had a bond retained for this period of time to cover defects that needed remedial work if he went bust..
Not sure how it all works now as they have lost a lot of pace recently and Carrillion have taken over from Eaga. My experience of Carrillion is that they can't organise a crap in a lavatory. I know a few years ago they were very hot on customer complaints and getting a local councillor involved normally got things moving pretty quick!
Did you contact Eaga/Carrillion/Warmfront or the installer direct?
