Steven serviced our alarm and replaced the keypad as well as fitting an additional sensor. Fantastic service & excellent value for money. I would definitely recommend SD Security.

Excellent Service

I contacted SD Securities and Stephen came out very quickly to provide me a quote for a house alarm and security cameras. Once we decided to go with him he was able to fit us in very promptly and came and did an incredible job. I would 100% recommend him to anyone.
