Hi, I need advice on a private parking fine.
I work for Northern Powergrid and was doing essential electricity infrastructure work on a substation in Sheffield on 5th Dec 2024 — the same substation that feeds power to the car park ANPR system.
I parked in the Broomhill Rooftop Pay Car Park (Excel Parking). I paid for three sessions: 08:41–09:41, 10:22–11:22, and 11:22–12:22. There was a 41-minute gap between 09:41 and 10:22 where I didn’t pay.
I couldn’t leave site to top up because I was working on live high-voltage equipment — leaving would have breached my duties under Health & Safety law and the Electricity at Work Regs.
Excel rejected my appeal even after I explained this and provided evidence.
Now ELMS Legal is chasing me for £170, threatening court action.
My questions are:
- Does my role doing statutory electrical work help my case?
- Could I argue frustration of contract or public duty defence?
- Does my health & safety duty give me a legal reason not to have renewed the ticket?
- I made payments before and after — does that weaken their claim?
- Should I defend this in court if it goes that far?
Any advice appreciated.
