Andy Teitge at Somerville Auto Electrics, is a good honest person.
Reasonably priced and always ready to help.
Have had our trailer and caravan wiring repaired by him and he spent quite some time tracing a fault on the caravan without any extra cost.

These guys really know their stuff, I took my car to the manufacturer, they said they'd fixed it but it still was playing up. It wouldn't start sometimes. Andy knew what it was straight away and fixed it within half an hour. I got my car back and didn't pay through the nose. Also they had these jump start packs which I bought, it charges everything and even starts my car.
