I was approached by a lady over the road who wanted some radiators fitting urgently. I quoted her £20 per hour regardless of when. Spent 5 hours one day & 4 hours the next (Saturday) & billed them £180.
Don't really know them that well, just neighbours.
Work involved running complete new pipework with soldered joins (they didn't want compression), linking rads through walls, fixing rads to walls etc.
Customer supplied pipe & most fittings.
I didn't charge for the hour I spent getting the fittings he hadn't ordered, nor did I charge for the half dozen fittings from my toolbox. Job was a good un if I say so myself.
They complained about the bill, saying that they thought 'mates rates' would be much cheaper. They thought about £130 would be nearer. I don't really want to fall out with neighbours, so I negotiated to £150 to finalise the matter.
So, I ended up with £16 ish per hour for a 100% quality job. Doesn't sound dear to me. Last time I agree to 'mates rates'.
I reckon £20 per hour is cheap for a plumber?
