  • Mr Evans Denmead, Hampshire

    Technician was excellent, took care of my property, hoovered as he went along and took the time to channel the wiring properly and back filled as required – Absolutely first class service.  I was hesitant to use CIA but friends recommended them and I am very pleased that I followed up on their advice.
