“Sincere thanks for your stirling efforts in turning this around for us so quickly…I can’t thank you enough for your help; you are a great advocate to your company and my only disappointment is that so many others suppliers don’t emulate this level of customer excellence.

"Niche market security manufacturer Hoyles Electronics Developments Ltd, have recently supplied over twenty door interlocking units all for installation in small laboratories and cleanrooms for Eden Bio Design a large Pharmaceutical company based in Speke Liverpool. All the IG432 interlock units are being used to replace existing equipment installed by Unique Integrated Systems over ten years ago. After installation Eden Bio needed to change the specification to allow the air to stabilize for 30 seconds after the doors had been used. Hoyles were able to modify the software quickly to accommodate the changes needed. Mark Ashall Operations Director at Unique says… ‘I can confidently recommend Hoyles Electronics as a KISS ‘Keep It Simple Solution’ product manufacturer and supplier to the trade. We regularly use the Hoyles IG432 interlocks as we are confident in getting great result for us as an installer and for our customer.’”

“As a major supplier to the UK’s Retail and Banking sectors providing both Physical and Electronic Security Solutions, Sec 2 Security Limited had been approached by one of the World’s Largest Cash in Transit Companies asking for help to overcome a serious problem with raids on its staff and customers worldwide. We realised that this was a challenging task and one that required significant and vast experience within the electronic interlocking marketplace. We approached Stephen Hoyles, Director of Hoyles Electronic Developments with our idea and initial prototype. We were extremely impressed at the attentiveness and speed that the Hoyles Team showed in helping develop our prototype into the product that it is today. It would be fair to say that the product exceeds all our expectations due to the dedicated way in which Hoyles work with their customers. Together we overcame almost impossible issues and today we are proud to state that Hoyles Electronic Developments are our sole strategic supplier for specialist interlocking solutions."
