You definitely need to.I have already paid for it, and I will be going back for clarification.
That might possibly be a factor, but moving the CU a bit doesn't necessarily impact much on the cost of the job. How close is the CU to the gas meter/pipes at present? - per the guidelines (not regulations), it only needs to be 150 mm away from gas pipes (and cables should be 25 mm from gas pipes).As for replacing the CU, the company that have quoted for the works say they will have to move the CU location to be away from the gas meter, which is currently right next to the CU, which is presumably why the cost is so high.
Kind Regards, John
