again, that's not how it works, I'm looking at my paperwork as we speak.

You are talking about your experience of one crossover in one location.  I'm talking about my experience of dealing with hundreds of crossovers, and with many different highway authorities.

In your case the highway authority employed the contractor and you paid the council.  Therefore it is a variation on the option 1 I outlined above.

Option 2 involves the property owner employing the contractor directly.  You didn't do that.

the dropped kerb is not yours, it's part of the road network, hence public. as such, all you do is instruct the council to build something for you. the whole point of using a pre-approved contractor is that should anything go wrong, they/the council is responsible and will absorb the costs.

The dropped kerb is part of the highway, there is no dispute about that.

The rest of that paragraph is simply wrong in all respects.
