Our own DBS-checked engineers design, install and service fire alarms, CCTV, intruder alarms, access control, door entry and AOV smoke ventilation.
We work across all 32 London boroughs, with most of our work in South London and Zone 1, providing BS 5839 fire alarm systems, HD CCTV, door entry and access control for homes, commercial premises, HMOs and blocks of flats. Every installation and service visit is certificated.

"Security Red Alert are an amazing company! My mums fuse board was really old and the electric kept tripping. I needed an up to date fuse board installed as an emergency. Security Red Alert contacted me immediately, went to my mums house to check out the situation, gave me a quote, and completed the work the next day. They have great communication, are super efficient, polite, knowledgeable, and extremely professional. They are fairly priced and supply you with a certificate on completion of the work. I recommend this company to anybody that requires electrical work! 10/10."

"I recently hired Security Red Alert to rewire my home, and I couldn't be more pleased with the results. From start to finish, their professionalism and expertise were evident. The team arrived promptly, worked efficiently, and paid close attention to every detail. Akthar made sure to explain the process clearly and addressed all my questions with patience and knowledge. The quality of their work was outstanding, and they ensured everything was up to code. They also kept the workspace tidy and cleaned up thoroughly once the job was done. If you're looking for a reliable and skilled team for electrical work, I highly recommend Security Red Alert. Their exceptional service and dedication to customer satisfaction truly set them apart!"

Fire & Security Questions, Answered
How much does CCTV installation cost in London?
Professionally installed CCTV in London starts from £600 for a small 4K system with recording and app viewing. Most home and small-business systems with two to four cameras fall between £600 and £1,500; larger commercial systems are quoted after a free site survey. Security Red Alert provides free, no-obligation site surveys before quoting.
