Phil W - Industrial Unit, Bournemouth

I have used Onetec for a number of years and have always been amazed by their ability to tackle any job head on and produce the results we have required. Their technical expertise has allowed us to create some custom access control, security and energy saving applications for the business that have realised their ROI within a year. Onetec’s employees are always professional courteous and work to the highest standard possible even ensuring they clean up after themselves. I would have no problem in recommending them to anyone considering using them and will continue to use them myself for years to come.

We were contacted by Onetec Ltd to install some glass partitioning next to some turnstiles that they were going to be fitting at an office complex in Slough. Our contact was Dave Feast and he was the main contractor for these works. All information supplied was accurate and detailed and their works were completed as planned allowing us to complete our element on time. This was a very well run project and would highly recommend. We would definitely work with them again
