i worked for them a couple of years ago. Worst company i have ever worked for. They are franchised so run by people who have never picked a spanner up before and run ruthlessly. The "overtime" was not optional, at 4.45 you might get a call with 2 more jobs to attend at different ends of the city. I was paid £11 per job no matter where it was or how long it took.
Did one at hour and half drive, 3 hour repair and hour half home at 3 in the morning all for £11.
i cant even take any positives from my experience with them im afraid
told the boss lady to F off and walked out after 6 months and started on my own
