Prime Secure’s CCTV Towers and Security Guards offer tremendous protection and a highly visible deterrent for your construction site but, should an incident occur, effective protocols must be initiated immediately. The longer it takes for your site to be attended in the event of an intrusion, the greater the risk of damage or theft occurring.

We provide keyholding and alarm response services to building sites throughout the UK. Our round the clock service ensures your site is in the safe hands of SIA licensed security personnel and a professional keyholding service ensures that pre-agreed and effective protocols are initiated in the event of an intrusion on-site.

With Prime Secure’s keyholding service your keys will be kept safe, secure and readily available to our experienced and highly-trained security officers who will spring into action as soon as an issue is detected.

Once an incident has been detected, our security officers will be immediately deployed to your site. With our UK wide coverage, you’re never far from a Prime Secure security officer. No matter the time or location, we will have experienced personnel on-site as soon as possible. once on-site our staff will initiate pre-agreed protocols and thoroughly investigate your site to identify the source of the alarm activation and act accordingly.

Why use a keyholding service?

There are many reasons to take advantage of Prime Secure’s keyholding services.

Prime Secure keyholders

Our keyholding security officers are extensively trained, SIA licensed and undergo a rigorous development program to ensure the quality of the Prime Secure keyholding service. We are one of the few security companies in the UK to invest heavily in keyholding services and work closely with a range of service partners across the nation to keep response times as low as possible.

Incident response

Our seasoned security officers are SIA licensed and trained in dealing with incidents where intruders may still be on site. We also work with you to agree on a set of protocols and procedures that are initiated the moment our security team arrive on-site following the detection of an intrusion. The actions of our fully trained SIA licensed security officers will be specifically designed for your site and your business, no matter what security issues they face.

Should the alert turn out to be a false alarm, we will reset the alarm system, conduct vacant property checks to ensure that nothing is amiss, before locking up and leaving the premises.

How quickly can our keyholders respond?

With UK wide coverage we have keyholding security officers that can respond quickly to any intrusion detected on your construction site. Our national reach means we don’t subcontract out work to local companies and your site will only be attended by experienced and extensively trained Prime Secure keyholders, capable of carrying out a full range of security services.

Using site employees as keyholders

Some construction site managers opt to nominate a member of staff as designated keyholder. Considering the cost of keyholding is typically around £1 a day this option saves little money and when you consider the downsides of this option, is very much a false economy.


In our experience, the likelihood of a site employee providing the same level of service as a qualified keyholder is remote and, given the high value of equipment and materials on-site, any failure to do the following can result in significant loss of money and time.

Opening & closing

One of the main responsibilities keyholding involves is opening and closing the business or, locking and unlocking the property. Upon opening up the premises, the keyholder should inspect the property, deactivate the security system and switch on lights. When closing the property, it is the keyholder’s responsibility to do the same process in reverse, activating the security system and ensuring the premises is secure, locked, and primed to deal with a potential security breach.

We can also arrange for mobile patrols or other security services to be carried out by a security professional around the close of play as part of our key holding services to ensure all is well before the site is left empty.

Protecting your keys

Keyholding, naturally, will involve the protection of the keys 24 hours a day. They will also need to know the security code(s) for the alarm(s) and the keyholder must keep this information in the same place as the keys. If you were to hire an external security company to take on the keyholding role, you can be assured that protecting the keys would be dealt with professionally and securely at all times.

Emergency contact

As they can reset the alarm system, keyholders are often entrusted to be an emergency contact for the local police or a private security firm that monitors the property. This must be taken into consideration when selecting the right person for a keyholding position. They must be available, responsible and practical.

We have close contacts with the emergency services and will alert them immediately if required as part of our alarm response service, saving valuable time in the event of an emergency.

Why protect a construction site?

Each year the construction industry in the UK is victim to approximately £800 million of losses thanks to vandalism and theft, according to a report from insurers Allianz Cornhill, a sign that having a security firm act on your behalf is absolutely essential.

Their study shows that these huge losses are derived mostly from the costs of hiring replacement items, replacing those same items, business lost as a result, and increases in premiums from insurance companies.

Theft – The Chartered Institute of Building’s 2016 study on Crime in the Construction Industry reports that, of the 1,100 professionals surveyed from the construction sector, 21% had suffered theft the week they were surveyed. If that wasn’t bad enough, a massive 92% reported that they suffered from theft on an annual basis, with many experiencing it on a weekly or monthly basis!

Vandalism – Reported in the same CIOB study, 91% or participants surveyed stated that they had been the victims of vandalism. Fences and locks may put off the casual intruder, but to deter hardened criminals and prevent serious equipment damage, a CCTV Tower and other security service technologies are essential.

All these threats make having a key holding service provided by a professional keyholding company absolutely essential for all construction site and void property owners.
