What our customers say

What our customers say…

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.

I have relied on Onetec for many years now for all our electrical and alarm requirements and found them to be both prompt and professional on every occasion. I have no hesitation in recommending their services.

Chris BriantBOFA International Ltd.

RTI Estates have instructed Onetec for a number of years on all of our planned and reactive maintenance. We have put the contract up for tender on a couple of occasions, out of best practice to our site users, but even then Onetec remained competitive and gave us the best quote along with the best service. We would highly recommend them for their quality of work, reliability, professsionalism and fair pricing. Their staff and operatives are always friendly and happy to help, even when we call late in the day or just before the weekend!! Keep up the excellent work 🙂


Professional and knowledgeable from start to finish. From advising on the right CCTV solution for my industrial unit to the completion of installation, I have found all the staff to be friendly and helpful. Would highly recommend.

Onetec carry out the servicing on your fire/burglar alarm and the work is always carried out to high standard with minimal fuss. They also completed a complete new install for our new 1st floor, electrics, networking etc and worked around the builders causing no delays to my business, highly recommended.

Peter Jones

Onetec have recently installed a full range of Access Control at 2 of our university’s student accommodation inc. turnstiles with bespoke glass partitioning, CCTV and intercom. This is a big project to implement but they have always been readily available to pass on their knowledge and assist with any questions we have had. Would highly recommend this company.

David DoddSouthern Piped Services Ltd.

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.

We regularly use Onetec to assist with our Fire and Intruder alarms, CCTV and Emergency Lights. They have always given a first-class service, and their broad knowledge and advice on any issues that arise is always appreciated. Would highly recommend them whether it’s servicing, upgrade or a new installation that is required
