Highlights
"Hris has installed a top rate alarm and video door bell for our house. He is completely up to date on products available on the market, rather then rolling out “the same old things”. He is extremely knowledgeable about the products he installs and is incredibly hardworking, punctual and professional. If you are looking for a reliable, modern, excellent value installer please give Chris at Diligent Security a call. It’s rare these days to find the dedication he offers. Highly Recommended"
"I was impressed with Chris. He is professional and fully up to date on new systems. He has installed a great alarm system for us today and completely the work professionally and on time. I shall be having him back to fit doorbell security. Thank you Chris for an excellent job."
"He was quick in his diagnosis of the problem, and quick in ordering the parts and fixing the problem. He was polite and knowledgable too."

Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check — a layer of accountability an unregistered trader doesn't offer. Around 5 years on the register also points to an established business rather than a brand-new one.
