If you have a heating crisis in the middle of a winter night, you want to know that you have good people to call. November last year I lost heat and called the Lamprey Energy number just before midnight. Despite the late hour I got through straight away to a real person. An hour later the technician had everything fixed and the heating was back to normal service. It’s a great comfort to have an energy company that’s so responsive when I need them. Thank you Lamprey Energy!
