Came out promptly, on a weekend, and sorted the problem out quickly. Highly professional from start to finish.
Our security alarm went off due to a low battery and the kids couldn’t sleep. Alex came straight over from the other side of London.
Thank you so much for fitting our alarm system. You were kind, helpful, and prompt. I felt very looked after.
Things people usually ask
Short, honest answers to the questions we hear most. Anything we’ve missed? Just give us a call.
Are your engineers professionally qualified?
Yes, we’re professionally qualified. In plain English, that means a properly independent body has checked our work meets the British Standards your insurer cares about. It’s also what you need for police response on a monitored alarm.
Which parts of London do you cover?
All of Greater London, including every major borough, plus Surrey, Hertfordshire, Buckinghamshire, Thurrock and Essex. Not sure if we cover your postcode? Drop us a call on 07848 247 247 and we’ll tell you straight away.
How much does CCTV cost?
Honest answer: it depends on what you need. The good news is the site survey and quote are free, the price we give you is fixed, and there are no surprise charges later. Most homes start around what a decent smartphone costs.
My alarm has gone off, can you come out tonight?
Yes. We run a 24/7 emergency callout service every day of the year, including bank holidays. Whether it’s a faulty alarm, a CCTV camera that’s gone down or a lockout, give us a ring and we’ll get someone out to you as quickly as we can.

Will my insurance company accept your work?
Yes. Every install we do is insurance approved, and we’ll give you a certificate of compliance you can send straight to your insurer. Quite a few customers see their premium drop afterwards.
