These are just associated costs you need to suck up as part of your works, why should your neighbour forgo their rights/protection to save you a few quid?
They are the maximum costs possible. You can incur no costs at all, but I wouldn't recommend that or expect that as no one would have any protection.
And also communication, I feel I may have mentioned that more than once?
