Mate of mine has asked me to install a dishwasher into a utility room next to his kitchen. There is no plumbing in that room. So i will need to run pipework from the kitchen cold mains, through the wall into the utility room. I then need to connect this up to the dishwasher. The I will need to go through the wall, install a waste upstand and out into the outside drainage.
I'm looking at charging £120 for this job (pipework and fittings, waste fittings etc included). Is this a fair price?
Note: just to add, i've called several local plumbers and got 5 estimates.
1) £450
2) £300
3) £270
4) £250
5) £150
Why such variation in the prices?
