The company I work for has received a "Notice of Trespass" in relation to one of our wagons being stopped on the roadside on a private industrial estate in Felixstowe. Note that this was not parking in a bay or layby but simply pulled up on a roadway (on yellow lines). This was recorded on CCTV. The agents, Proserve Enforecment Solutions issued a Notice for Trespass on 10th May for £100 (plus VAT) which we ignored in the same way as we would for a private company issuing a parking PCN. We have now received a second letter with a 50% additional charge suggesting that if payment is not received by Friday 1st June they "will" register the charge with the County Court. Usually the parking PCN's use the word "may" rather than "will". Are we in a different situation because they are using Trespass rather than just an ordinary parking notice? I would appreciate anyone's experience or advice with Proserve Enforcement or this type of notice.
