“It has been my privilege to have used the services of Grammar electrical since 2005; I mention John and Reuben as Stars in this organization. In all this time we have had nothing but exceptional service and quality workmanship. Wonderful responses to our needs no matter how small the job. On occasions where we have required urgent work they have been able to accommodate all our needs. To the Grammar team, keep up the amazing work you do.”

Mike Carter – Campus Manager

“Grammar Electrical did a magnificent job in refitting an old tyre warehouse into a thriving café/restaurant. There were a number of significant hurdles they had to cross in dealing with an old existing structure, and they were excellent in making the project work brilliantly form an electrical perspective. They were flexible, timely and always willing to adapt to the evolving needs of us as clients. We had a few unusual elements in the build and from all aspects of cabling data/AV/electrical, they found solutions to our needs.”
