As one of the very last security companies that still operates from an office in central London, with friendly and experienced staff who are dedicated to providing excellent customer service.

We pride ourselves in our flexible and efficient service that truly puts the customer first.

Why Have a Maintenance Agreement?

It is a well known fact that regularly maintained systems are cheaper to run in the long term and much more reliable day to day. Police forces require all monitored intruder alarms to be professionally maintained in order to get a police response. Insurance companies often make this a requirement too.

In addition, our contracts give you 24/7 access to engineers, maximum 4 hour response times and preferential rates for call outs and replacement equipment.

We’re There For You

Most of our staff have been with SDS for a long time meaning they have had time to form strong relationships with clients. The same goes for our home security specialists, we always try to send an engineer that you are familiar with.

When routine servicing comes around we offer guaranteed AM/PM appointments. However, if possible, we can carry out remote diagnostics to save you time.

Home Security Takeovers

We are happy to takeover or repair non-SDS systems. This includes emergency call-outs, depending on availability. We tend to send a surveyor to assess the system who then provides a quote. If you’re interested in a free surveyor or want to know more about our maintenance services, please don’t hesitate to get in contact.

Testimonials

I was very happy with the work SDS did. On time and to budget and the installer was very tidy and found a way to install the system with minimal internal or external property damage.
Mr Cass
I have used SDS Security Ltd to provide my security needs for the last 19 years. I have chosen to stay with them for this period of time as their staff are always reliable, courteous and helpful. Having been a customer of SDS Security Ltd over this length of time it is apparent that there good reputation has grown over the years and I would have no hesitation in recommending their services.
Angela Holy-Hasted
We have been SDS customers for 12 years and cannot fault the service they provide. I have total faith in their security services. The customer service is exceptional and when I do stupid things like put the alarm on from habit forgetting I am leaving my mum in the house they are very understanding! When we renovated our home we went through all options available to us and I feel we got really good advice and were not sold anything we didn't need.
