"We engaged with GSH at the beginning of the new Hospitality Building Project in October 2016 and we have used them ever since. Completing all Electrical work from Design to Completion, within the project and also the new stand extension. We have found Gavin and his team to be extremely efficient and easy to work with whether it be on a building site or within a customer environment such as our restaurant. GSH work has been of the highest standard and I would highly recommend them. Nothing has been too much trouble for Gavin and his team and they are always there to cover any unexpected emergency no matter the time of day or night. That kind of service is why we continue to use them."
