Monitoring, Response & Key Holding

Permanex - Construction Site Security Monitoring Response Keyholding

Without the ability to effectively monitor all of our security systems, the data they deliver is useless. To best ensure the security of your construction site, temporary site or installation, or void property, we believe in going the extra mile.

Our monitoring station views all images and assesses any activation remotely. Over the years, however, we have also augmented our own security monitoring, response and key holding services by partnering with some of the most professional, trusted, and well-respected security firms in the UK—all of us here at your disposal should anything go wrong.


Our alarm monitoring centers are available 24/7, 365 days a week to respond to security breaches of all kinds, from intruders, vandals, and thieves to fire or accidents. Permanex monitors most of the alarms using your existing phone line or over secure mobile networks, to ensure we know exactly how your alarm is performing, whether you are on site or not.

Security Response MotorbikeAs part of our TOTAL SOLUTION, we are the only company in the UK to offer clients regular patrol teams, intruder/CCTV/fire systems and rapid-response motorbike units (within M25)—all controlled from the only UK central station to have a live back-up facility in case of shutdown—you can put your site’s security in our hands in full confidence. We only work with the most capable security teams and the most intelligent technologies, so that all security issues are dealt with quickly, professionally, and without any need to contact you. If a response team is called to the site overnight to handle a threatening situation, we present the site manager or foreman a detailed record of events, imagery, and an email report the following morning. That’s our guarantee.


We haven’t earned our reputation by resting on our laurels. We love the challenge of staying ahead of game by developing new technologies to make our services even better. Our rapid-response motorbike units are a perfect example of the lengths to which we’ll go to ensure that no stone is left unturned.

In order to make sure our clients are covered throughout the UK, we have a longstanding, national contract with Nikaro, and we also have our own dedicated response company CPR (CityPatrol & Response Ltd) withing the M25.
