George randomly hit the keyboard and produced:

Ask the BCO to investigate whether or not it complies with BR (it
probably does) with the escape of fumes being directly into your
property

It complies, in that there's nothing in the Approved Document to say
where an outlet should or shouldn't discharge. I've had similar cases
before. The best I can do is to point out to the owner that if their
neighbour ever did build something against their wall, they'd block
the ventilation.

I'm sure that outlet is ugly, so you'll want to put some trellis
against their wall with some climbing plants on it, won't you?
