Checklist Security was recommended to us by a trusted friend who had just had an alarm installed by Neil. We knew, if he was happy, we probably would be too. And we weren't disappointed. Our situation was quite complex and involved data cabling as well as two linked alarms, but Neil understood instantly what was needed and how best to achieve it. He was very helpful, accommodating and delightful to deal with and his workmanship was absolutely A1. He found his way into the tiniest, remote ceiling spaces and made it look easy. Follow-up service when we needed it was outstanding - extremely prompt and he remembered the tiniest details of our installation a couple of years later. As the charges were extremely reasonable, the workmanship superb and the technical knowledge second to none, we would never use or recommend any other security company. We have dealt with several others in the past since 1981 and we know excellence when we come across it. We simply can't fault Neil and Checklist.
