About Us
We deliver manned guarding, door supervision, concierge, fire marshals, mobile patrols, keyholding and alarm response, CCTV and wireless detection, and commercial cleaning.
Overt means done or shown openly; plainly apparent. We built the company on that meaning: clear pricing, clear communication, and an infrastructure that allows real-time visibilit— — from incident reporting to patrol logs and on-site tasks. Full visibility is what makes us Overt.
Our Ethos
Integrity Through Transparency
Personal Care, Nationwide Strength
Innovation in Action


Our Systems
This is what makes the nationwide model work.
Real-time visibility is the backbone of that model:
- Incident reports, patrol logs and on-site tasks visible as they are completed
- One method for booking, deploying and checking a shift, on every site
- People and technology planned together, so cover is neither wasted nor short
- A named account contact, with director involvement on complex work
Officers are SIA licensed. SafeContractor independently tests our health and safety, training and risk controls. ISO 14001 independently tests how we manage our environmental impact. We stay current with the requirements of the Security Industry Authority.
That is the standard for every client. It is also why we can work with organisations that require a higher level of scrutiny, including Cardiff Council, Vale of Glamorgan Council and Ringley Group.
Social value and local employment
The community keeps the jobs. The client keeps the record. Supervision stays close to the work.
That is the social value: local employment that lasts, and a standard that can be checked.

The vision
A regulated, accredited operator that stays current with the Security Industry Authority, and that can take a single site or a UK-wide portfolio without the service changing.
That adaptability, and the infrastructure behind it, is what has made Overt one of the leading security and facilities companies in the UK — a known solution for clients who need cover they can see and keep.
Our Happy Customers
"I have worked with Overt for over five years, and they consistently provide waking watch, concierge, and security services across our sites. They are reliable, quick to respond, and always reassuring whenever they are on the job. I would highly recommend Overt and would not trust another company with our requirements."
"I have worked with Overt on a number of projects across the Council. They are very professional and demonstrate their full experience and expertise, particularly when it comes to more intrusive or complex jobs.
Steve, the Director, has never failed to impress me with the level of industry knowledge and support he provides. I would have no hesitation in recommending Overt for security-related requirements."
"I have worked closely with Overt for several years now. They have been providing waking watch services across a number of apartment blocks that we oversee. Throughout this time, we have consistently received a reliable and professional service from their team. I would be happy to recommend them to others requiring similar provisions."
"As a company who holds other client's stock and valuable trucks and trailers, security is a necessity. At the drop of a hat, Overt Security stepped in and have safeguarded our premises, vehicles and all medical stock. I would like to give a big thank you to Overt and the guards, within times of worry. You have saved myself and my clients from one less major worry knowing our stock and valuables are secure and safe."
"I was recommended Overt Security by a friend, they met with us on the day of enquiry and came to view the venue. We discussed the events held at the Museum and they were able to suggest and guide us with the staff set up, which was a great help. Upon request, Overt also provided Welsh speaking security guards, which was exactly what we were looking for. We have since used Overt Security on a number of occasions and will continue in the future."
"We have been using Overt Security for the past three years to provide event security & security guards across our Academy Coffee establishments. Throughout this time, we have consistently received a professional and reliable service that gives us complete peace of mind. I would highly recommend Overt for any venue's security needs."
"Overt have provided us with mobile patrol services for a few years now. They have always been highly professional, and it gives us great peace of mind knowing our sites are being regularly checked.
We have also used their wireless detection system and security guards when needed. They are quick to respond, efficient, and have helped me deal with several emergencies over the years.
I wouldn't hesitate to recommend Overt for anyone looking for reliable security services."
"Overt installed a CCTV tower with 24-hour monitoring on one of our sites and we couldn't be happier with the service. The whole process was easy and straightforward from start to finish."
"Overt assisted us with our end of year cleans and they were excellent. They were quick, effective, and extremely well organised, which meant we had no involvement at all and could trust that the job was being done properly.
Their team handled everything smoothly from start to finish. It was a huge weight off our shoulders during a very busy period.
I would definitely recommend Overt for any cleaning or end-of-tenancy projects."
