  • First Class service

    10Verified Review

    It is rare nowadays to find a company that offers great service. But that is exactly what i received from Gardian. From the time i requested a quote for a CCTV system i received a first class service. Darren visited, provided a quote quickly, kept me updated on a start time. The fitting was professionally undertaken and Darren comprehensively explained everything and helped with any queries afterwards. I highly recommend Gardian as a professional, efficient and friendly company.

  • We would recommend Gardian without hesitation.

    10Verified Review

    We commissioned Gardian to completely replace our burglar alarm system. Darren is very professional to work with - everything was planned well in advance and executed seamlessly. Timing and costing was exactly as he quoted. We were delighted with the system - which he gave full instructions for use and is very UI friendly. We would recommend Gardian without hesitation.
