Will it make a mess – will the garden be dug up?

If we repair a leak, this will involve digging a hole. If Find 'n' Fix replace a pipe, where possible we use a pipe-pulling “mole” which effectively drills underground and avoids the need to dig a trench in your garden/drive to a certain extent. However, we will probably have to make a succession of small holes, but again only a survey will determine how much digging has to be done.
