I've submitted it now (took me all morning), explained the need for Part L and how much I estimate it would cost extra. The quote was roughly 3,500 without as there is no existing heating system in the property so it would push it well in 4,000 mark. If they opt not too then I'll get it in writing on a pre job agreement, with a signature. It's tricky this stuff, especially considering the extra wiring involved (I somehow doubt customers will be willing to pay 1000 plus for all singing and dancing wireless zone rad valves). Genuinely just wish the manufacturers would simplify the problem for us all, sooner rather than later.
