Who is responsible for the manhole in my garden?

This all depends on who is responsible for the pipe that is below the manhole or inspection chamber. If the manhole is in your garden and is on a pipe that only serves your property (a drain) then it will be your responsibility. If it is on a pipe that serves you and your neighbours (a sewer) then it will most likely be United Utilities responsibility.

If you have a problem with a manhole outside your property, on the footpath or in the road, which is on a pipe that only serves your property (a lateral drain) then because of the change in legislation from October 2011, this would also be United Utilities responsibilty.

We understand it can sometimes be complicated to know who is responsible so if you think the manhole may be United Utilities responsibility after reading the above then give us a call and we'll come to check it out.
