Fire Alarm Repair

“Marcus is a great fire alarm technician. Took real pride in his work. There was one recurring fault (related to an earth warning) which he took it upon himself to fix. He knew the systems inside out and the British Standards. I would not trust my fire alarm with anyone else. Well done SDS, and well done Marcus.”

Burglar alarm installation

“I recently had to have my burglar alarm replaced and am very happy with the work done by SDS. They provided excellent advice on my requirements and I was pleased with the way they installed the system. Clearly it's vital to have a company who you can rely on and I've always found SDS very reliable, competent and trustworthy.”
