Well I did the math on this job by getting the prices for all the bits and bobs (and no, I didn't get them to install any rads) and adding a supposed labor charge
I matched their total by adding about 5% to the trade purchase price of all parts, (I'm sure I've missed out a fair bit, and they did a small amount of building and repair work) and assuming that the 2 guys here are charged out at £45 per hour. On top of everything I did get a 210Ltr Albion recovery tank for the price of the next smaller one down.
They may be expensive, but, the work is very tidy, they arrived on time at
8am each day, I get a 6 year warranty, good call out times - should I need to call them, 6 years low rate payment option (which was the deal clincher), and after seeing so many 'Rogue trader' programmes on TV I just didn't want to risk using anybody else.Thanks for all your help
