Sorry as a landlord and home owner, I expect the person I
pay to design a system and install the boiler to recommend the best boiler for me, including having a good value manufacturer's service plan.
Telling a tenant that Ideal cannot come out to fit their boiler on Christmas day, is a lot better than trying to make a tenant believe that I can’t find any GS person to come out.
Any landlord reading this should join LNPG
http://www.lnpg.co.uk/compare-pts-prices.php, and then you will see just how much cheaper real trade prices are compared to what most installers pretend they are paying. (PS the buying power of LNPG members is more than most national house builders.)
A GS person fitting a boiler that the landlord brought var LNPG should be able to make a lot more money for the day’s work by charging a realistic rate for labour, then the GS person that pretends to pass on a trade discount, when the real discount a normal local independent GS person gets is not great anyway. (As well as remaining under the vat limit)
However not as bad as kitchen fitters, where both Magnet and Hoydens will provide fake invoices to kitchen fitters, so the fitter can make it look like they are passing on their the 30% trade discount. The true trade discount for kitchens are 70% plus.
