Assuming a labour cost of £80 per hour, even a chimp could replace 4

£360 for the labour = £460. Tell me how you'd bump that up to £2,240?

I thought it was about £700 quoted for the valves. and 4 an hour is
rather fast; valves often differ in size and pipework has to be
modified.

Or is that really an inconvenient truth?

Not really. I prefer to stick to facts.

Well, your idea of the facts according to the 'Greenwash Dictionary'.
