    Whats the best way to dig a trench for extension footings if its beside an existing extension (neighbours), no digger as terraced house.

    If you mean because of getting the digger around the back, you can get diggers that go through a doorway.

    Without a digger, you're stuck with handheld breakers, spades and if the ground is tough a pick-mattock.

    Depending on when their extension was built, it'll likely have deepish foundations anyway; you may only need to go as deep as theirs which shouldn't cause any issues.

    Unless you've already had the ground checked independantly you'd normal dig to the 1m depth assuming normal foundations. Depending on what you find, 1m may be enough. If you need deeper, worry then.

    It depends on the level of ineptitude of the person holding the shovel.

    If you only go as deep as theirs it's OK. If you need to go deeper for some random reason, then you'll need to shore the ground below their footings, and you should be serving a PW notice on them in that case.

    Yes.

    We had an incident local to me a few years back, whereby a builder excavated along the whole gable end of a neighbouring building. It collapsed.

    Subsequently local building inspectors were nervous. In a similar scenario (another local job) we had to do something similar, i.e. dig along side an existing building. We ended up digging hit and miss trenches, concreting in stages.
