I just paid £650 labour and ‘standard’ parts, but including new 3m section of gas pipe and 3m of drain pipe above normal.
Direct replacement in walk in cupboard, easy underfloor access, same flue exit etc
It was a long day for the two of them – they were there back of 8am, and just clearing off at 5:30. They did flush the system, but said it was clean enough anyway as I have been changing all the radiators bit by bit, and seem to have done a good neat job.
I bought all the parts myself, as I could get a better deal with some hunting, saving a further £200 and getting better timeclock – so Ideal Logic+ 30 with extended flue, weather compensation kit, magnetic filter thing and wireless stat/clock came to £1060 delivered.
This was last week by the way, central Scotland.
