    NSI Gold Certified for 21 Consecutive Years

    SDS Security is a fully approved NSI ‘Gold’ company. Gold status is only awarded to companies who consistently meet the industry’s highest standards. SDS employs their own personnel and doesn’t use sub-contractors on an ad hoc basis. You can therefore rest assured in the knowledge that all staff have been security screened in accordance to the latest ACPO and NSI requirements.


    1. Complete Service

    We offer free no-obligation consultations and inspections by highly trained and screened staff, many of which have been with the business for over a decade (we don’t use sub-contractors). We’ll educate and work with you to ensure you’re getting exactly what you want and need. From first enquiry to final payment we endeavour to be everything you need in a security company.

    2. Complete Security

    We’ll recommend a bespoke combination of security solutions to match your requirements and keep your home or business safe from intruders & fire. While we carry the latest and most advanced products on offer for home & business security, we’ll never sell you anything you don’t need. We’ll also conduct a yearly check so you’ll rest easy knowing you’re always fully protected.

    3. We’re Quick & Leave No Mess

    Your time is precious so we work around your busy schedule. However, we’ll happily sit with you and take you through everything in plain english before we leave. Any work carried out comes with a one year guarantee and no mess is left behind.

    4. Hidden In Plain View

    We’ve got a range of aesthetically pleasing alarms, sensors and equipment that we professionally install with minimal disruption to your home or business. Where possible all wiring and devices are hidden in cupboards, under floorboards or under the edge of carpets to ensure your security system is as unobtrusive as possible

    5. Quick Response

    In times of need, our engineers are with you inside 4 hours – usually much quicker (and we don’t charge extra for emergency call outs). Your peace of mind is our priority.

    6. We Care About Aftercare

    Most of our customers have been with us for many years. That is because we make sure we have enough capacity to respond quickly when needed. You won’t be waiting weeks for an issue to be rectified or queries answered.

    7. NSI Gold

    For over 25 years we’ve held the coveted NSI Gold accreditation for the highest standards in intruder, access and CCTV products, installation and maintenance – the highest accolade in our industry.

    8. The Latest Technology

    Our roots might rest in the 20th century but our security systems certainly don’t! Our new App allows you to control and monitor your home & business security from your phone or tablet.

    9. System Takeovers

    Whether you’ve just moved house or have been with your previous supplier for a while we can take over any system so you benefit from our robust security checks and friendly, responsive service.

    10. Full Transparency

    Whether the first appointment or your 10th annual service call, you’ll know exactly what time we’re coming, how long we expect to be and when you can expect to hear from us again. All documentation and estimates are clear so you know exactly what you’re paying for.
