What our customers say

Having started in the UPS business a few years ago I soon realised I needed professional assistance when it came to Bypass and DC panels. The professionalism and technical support I have received from RB1 has been invaluable. The end solution has always been the correct spec required and delivered in the given timeframe making in my opinion their service second to none.
Heather SharpSales and Service Administrator - Power Saver LTD
We have been working with the guys at RB1 for a few years now. The products they manufacture and the service they provide us with is always of the highest standard. They have manufactured a number of bespoke AC and DC panels for us when we have had some unusual requirements and our engineers find the panels great to work with. Nothing is ever too much trouble, if we have urgent requirements or need advice they are always willing to help us out. Since we started working with RB1 we don’t use any other panel manufacturer for UPS installations.
Gavin BanksManaging Director - Source UPS
We have worked with RB1 for a number of years and have always been impressed by their ability to deliver excellent technical solutions in any environment and adapt to the challenges that come from service work. Effective communication is the key to working together and the RB1 engineering team’s experience and understanding of the products and solutions allow them to add a genuine benefit to any project they take on.
Cliff CheethamBusiness Development Manager – Secure Power Ltd
RB1 have been manufacturing AC & DC panels for us for a while; the guys are great, friendly and are always happy to help. The lead-time is really good and have managed to turn things round in a few days for urgent requirements. Any minor errors are fixed no questions asked and in the past have offered to go to site and correct. The panels are labelled clearly both internally and externally with our company name and contact details along with warning labels and even details of torque settings of terminals etc. The safety screens are solid and the ones inside the bypass switch have a safety device fitted as standard that prevents inadvertent switching. The guys at RB1 will also help with bespoke requests and are very helpful. The panels are always delivered well wrapped and are delivered on time. Absolutely fantastic.
Neil SydenhamSales Application Manager
