Is this a reasonable cost for plumbing first fix?

This feels a bit high - what’s the opinion here?

 

Just before receiving this, I’ve been looking at running the pipework from plant room to the end points, then this came in (I’m now definitely considering running the pipework myself).

 

Approximate scope:

First fix plumbing pipework install. Only installing a mains connection point in the plant room (leaving the UFH / DHW / ASHP to others).

260sqm, 4 bed house with kitchen sink, dishwasher, freezer with water/ice dispenser, downstairs WC, washing machine, family bathroom & 2 en-suite. Doesn’t include bathroom installation (just pipes to the correct positions in the wall).

 

Labour cost £2,750.00 for all pipe installation (not bathroom install)

Materials cost £1,780.00 For all materials as above based on 28mm copper main to plank room plus fittings and stop cocks plus 22mm hep2o pipe and fittings for the hot and cold runs with 15mm hep 20 and 15mm copper spurs. Also, isolation valves to toilets, sinks, bath and showers.

 

Thoughts? Experience elsewhere?

If you have the time and inclination then it’s doable, work out the pipe runs to minimise crossovers and interference from other services if space is tight, go buy rolls of said pipe and clips to keep it tidy and go for it.  Many of us have trod this path, and history shows that we do like a good plumbing thread if you are so minded to let others have their 2p worth.  Biggest minor issues are how to bring the pipe work tidily into plant room if having individual runs, you can end up with 20 or so individual pipes.  And the various wall plate elbows and terminations at the end point.  I’m not sure it’s 4 and half grands worth of work in total, but in this day and age where labour costs mucho money then I’d diy it.

@crispy_wafer thanks - we do like some of the more doable DIY and are in need of controlling the budget, so doing this is very much worth our time! I also think I am more focussed on tidy routing of services…

My comments 

22mm main run for DHW, will take an utter age to get hot water out the tap. You really want a manifold system. Mine is DHW cylinder - 15mm to manifold central location, then from manifold 15mm run to each wet room and spur from there.

 

No comment on price

22mm backbone is fine if there’s a hot return. 
 

Otherwise, just painfully slow to get hot water from basin taps.

 

Avoid.
