What customers say
Yet again Paul and the staff at Onsite Electrical have rescued me. Ernie My electric van is a thirsty beast in the winter and needs proper charging overnight. Paul and his team installed a rapid charger for me and i’m no longer suffering from range anxiety. the standard of work has been exemplary and the pricing excellent...
I’ve used Onsite a couple of times, and found them to be punctual and efficient. Ciaran, who recently installed new ventilators in our bathrooms, was absolutely punctual at 8.00am. He worked swiftly and the ventilators are effective.
I would like to thank you for replacing my lights in my front room. I decided to put my exercise pole in the front room and was concerned that the fan light might have been in the way. Ray even found the beam that the pole needed to be below.
