Looking for Electricians

Hello, When we bought this house there was a summer house at the bottom of the garden with a cable for the light going along the fence and into the house (I suppose it goes into the house, but I could check it only to the edge of the patio). We took the summer house down, but the cable is still there and I would need it checked and fixed – whatever is needed I also want to add a few more spotlights in the kitchen/dinner and replace some in the bathroom. Thank you.
