and the other double THAT price! that's not the manufacturer...
What about when you buy direct from the manufactuer?
On a side note I have just come back from installing a load of new smart controls for a house heating system.
When I powered it all back on I wondered why the boiler kicked in immediately.
30 seconds later I found that the installers hadn't removed the link wire in the boiler control box.
Dicks.
Don't know if it was a big boy, or a local firm.
But even worse was that BG had been servicing it for several years; and not a single person noticed until I went there.
im not sure about other manufacturers to be honest but the one I know you cant buy directly from them anyway and you have to use the merchant... an example I can give is a PCB for an appliance... one merchant had it up at approx. £150+ VAT and another had it at over £400 inc vat. its all down to mark up... it was exactly the same part and the manufacturer would charge the same for each.
That sounds about the usual for BG!
How long had they been in?
I can probably guarantee that the installer would say "it didn't say that in the book" - where it actually did but via a wiring diagram that required a bit of logic and sense/working out... instead of "you need to remove the link, below is a pretty picture of a unicorn to help you understand this"
