Connecting AC pipe to Vent?

Spies

I bought this https://www.screwfix.com/p/manrose-flap-vent-brown-125-x-125mm/94320

But its the exact same diameter as the pipe I'm trying to connect, do I need some sort of adapter?

They are designed to be used with 125mm round ducting like this -

Is the pipe you have a flexible or solid one?

Yes.

Normally you would have a plate that mounts on the inside of the wall that lines up with that vented plate & then a length of corrugated (aluminium?) hose between the 2 through the wall. That internal plate then has a slightly smaller diameter spigot flange that the indoor pipe will then fit onto.

I've got a feeling that just doing with an adaptor & the external vent plate would be a breech of the building regs. At the very least it will look awful & be difficult to attach the internal pipe

It's only though a back door of a shop so I don't think building regs come into it.

Starting to think this hose is non-standard.

Building regs apply to almost all aspects of buildings, particularly the outer shell and features such as doors.

What varies is the process, and whether or not you have to get consent in advance etc.

Is the hose/vent going through the opening part of the door?
