I don't think Ms Crozier is responsible for Enforcing this particular racket, as she works for Oxfordshire County Council (and the BPA, of course) not the Environment Agency.
According to Oxfordshire County Council, who do all CPE in Oxfordshire, their CPE enforcement is done by our old (ahem) 'friends' NSL in Oxford, which, along with Abingdon and Wallingford are the only places in Oxfordshire where CPE exists, TVP being responsible for on street Enforcement everywhere else.
I suppose it is fairly inevitable that the Environment Agency contract goes to a BPA Ltd member company as most (if not all) PPCs belong to that particular organization.
Interestingly, District Enforcement gives it's "nature of business" as "other business support services" and lists no directors at Companies House, but as they are a Private Limited Company, I guess they don't have to?
