An ice-cream van parks outside my house every night after 19:00 playing loud distorted music/chimes. (My neighbour told me that it is a nuisance to her as well as her young kids want an ice-cream when they've gone to bed !)
I phoned local environmental health to complain giving them Registration number and the logo "Joe Bloggs Ices"
They have got back to me and said that they need to have the make of the vehicle and its colour before they can investigate.
Do they really need that info to identify the owner via the DVLA: I would have expected that they had privileged on-line access to the DVLA and they could just put reg in and get the details. Is that not the case? The officer from EH said that they need all info as they have to "send-off" a completed form to the DVLA.
