Our plumbers don't do trench works so we need a trench for our new waste pipe that currently comes down inside the back of our garage to run to our existing drain (just outside the front of the garage) and to run a new mains pipe across the shingle / grass drive to the border of our property so the water company can change the connection from the old lead pipe to the new one.
Marius and two of his team I took work for me, digging trenches and installing new water mains and waste pipes round the side of the house to link up with the main sewage. They finished the work quickly and to good standard. Marius communicated well with Building Control for me and was keen to ensure it was all signed off before he was happy the work was done. Would recommend to anyone.
