Looking at Streetview I wonder if the current arrangement is a piece of 'DIY' by a previous occupant. It is as already observed very close to the side junction though I'd have thought that could be mitigated for by removing/reducing the boundary hedge.

I think you need to have a proper conversation, with outcomes formally recorded, with the relevant Officers in the Council. You may need to involve your ward councillor and possibly professional advice. I wonder if @Happy Blue of this parish who is a Surveyor would comment?

Keep us posted.

Its the Highways Department,

I just don't see how they can apply current rules to something that predates the Highways Act 1980? I found on by house searches that planning permission was granted for vehicular access in 1967, and building control signed of the garage in 1970. if my self and others have enjoyed and used the current vehicle crossover point for almost 50 years I don't see that they can reverse it without a major event occurring?

A footnote to my earlier post.

This morning I was waiting for a bus home and opposite the bus stop, on a residential side-street, the two end houses, on the corner, had "crossings" that were right adjacent to the curved part of the kerb. It was impossible for the houses in question to have a dropped kerb less than 2/3 metres from the junction. Admittedly the road in question was a cul-de-sac, but I don't believe the 10-metre rule, which seems universal across different local authorities, is slavishly adhered to.
