I have been very impressed by the thoroughness of their work and the quality of the sub-contractor and equipment used on site. The project manager for the work has gone above and beyond the call of duty on numerous occasions and I have been very impressed by the professionalism of the Osborne Energy team and the management of the contractors on site. The work has been challenging due to the nature of the sites, but Osborne have succeeded and impressed all concerned. Overall, I would recommend Osborne Energy for LED replacement work very happily.”

“I have been thoroughly impressed with Osborne Energy and their commitment to assist with our projects as and when we have had to call upon them.
