What customers say

Based on genuine customer reviews

Bespoke installations following theft or accidental triggering form a large part of what reviewers describe about SDS Security across south London, covering intruder alarms, CCTV and fire protection for a restaurant in Peckham as well as private homes in London and Kent. Several customers note that they have remained with the firm for over a decade without considering an alternative, crediting efficient and reliable service delivered by staff who stay with the company long term.

Several accounts note the knowledge and friendliness of attending technicians and the responsiveness of the office team, with Ola, Donna, Anna and Debi Middleton named for explaining faults clearly, replying to emails promptly and talking customers through system resets without an engineer visit. A theme running through the feedback is the absence of pressure selling, with customers appreciating that no attempt is made to upsell on alarm maintenance.

Workmanship on replacement camera setups after a theft is described as thorough, and the company is credited with reacting quickly when alarms were set off accidentally, during a break-in or by builders on site, contacting the householder by phone and alerting the police where required. Fair pricing relative to the specification supplied is noted alongside prompt communication throughout.

We inherited the system from previous home owner so now pay the annual fee etc. It's the most antiquated difficult to use system that breaks constantly and then to get someone to fix it they charge 150 quid call out fee every time (even when it was due to a system upgrade their end). We have just resigned ourselves for it to be non operational now and hope we don't get burgled. It's terrible.

I just called SDS today to talk through the resetting of a friends alarm. I spoke to Anna (not an automated message) and she was absolutely brilliant. With her 26 years of experience, in a 6 second phone call, she was able to talk me through getting the system reset and back to working order!- amazing knowledge and customer care and ask for her if you need alarm advice in the future (unless of course, I’ve stolen her first!)- Lorna

We had a problem where our CCTV was stolen and we needed a bit of a bespoke solution to help prevent this from happening in the future. When I spoke to the company initially they were rather unhelpful and not really interested in looking at the specifics of our particular situation. I initially gave them a poor review which then triggered a far more helpful response from the company. Our new CCTV is now installed and is lot more secure thanks to the cooperative nature of the people involved.

SDS SECURITY, part of SPY ALARMS. Took half a dozen quotes from various security firms and I found SDS SECURITY value for money because their quote was of neither cheapest nor dearest. The system they installed was in line with what e needed in our property. Communication from the company very excellent. All my e-mails were answered promptly by various members of staff. Few of the staff members are namely Debi Middleton, Mellisa, Lucy VanAckerman, Anna Mcateer, Ola Worowska Aileen Thomas. Surveyor who came for the quote Nick Nazroo exlained the Intruder Alarm system fully and finally the Engineer Michal Klimaszewski installed our Intruder Burglar Alarm and he was friendly, co-operative and did tidy work. I have no hesitation in recommending this form. In my opinion one of the best in South London. RASIKLAL

We have been customers of SDS for 22 years both in London and Kent. Their service, efficiency and professionalism are excellent. They are always contactable (even at 1am on a Sunday/Monday when the alarm triggered and couldn't be turned off) and their engineers are courteous, professional and very good. I have absolutely no hesitation in highly recommending SDS and regularly to so to clients of mine looking to install or upgrade an alarm system.

My experience with SDS Security has been fantastic from the start! Ola has been extremely helpful and responsive via both email and on the phone and all the the technicians that have been on site have been really knowledgeable and friendly. We're a restaurant in Peckham and use them for our CCTV, intruder alarm and fire security. A definite 5*'s and I would highly recommend using their services!
