Lock and Unlock Services Northern England

Guaranteed Site Perimeter Integrity

Eliminate the “did I lock the back door?” anxiety. 

Our officers perform a full internal and external sweep, ensuring all windows, doors, and gates are bolted and alarms are set correctly every single night.

Reduced Risk to Your Employees

Lone working at the start or end of the day is a major safety liability.

By using a professional security team for “open and close” duties, you remove the risk of staff encountering intruders or being targeted for their keys.

Operational Efficiency & Punctuality

In an emergency, every second counts. On-site guards provide immediate intervention while emergency services are still en-route.

De-escalating a conflict or managing an evacuation, instant response minimises property damage and ensures the personal safety of everyone on-site.

Significant
Insurance Benefits

Technology records events, but guards interpret them in real-time.

By combining foot patrols with active surveillance monitoring, guards identify suspicious behaviour that automated systems might miss. 

Reliable Site Start-ups
& Secure Shutdowns

At Northern Security, we understand that the beginning and end of the day are when your premises are most vulnerable. Our service provides a disciplined, professional alternative to entrusting keys to junior staff or lone workers.

Our process is thorough and systematic:

Our mobile units arrive at your scheduled closing time. We conduct a “floor-to-floor” sweep to ensure no staff or intruders remain on-site, check that all fire exits and windows are locked, turn off unnecessary lighting/equipment, and set the alarm system.

We arrive ahead of your staff to unset the alarms, unlock main access points, and perform a perimeter check for any signs of attempted entry overnight, ensuring your team walks into a safe, ready-to-work environment.

Whether you run a single retail unit, a busy construction site, or a sprawling industrial estate, our service is tailored to your specific operational hours. We can also provide facilitated access for out-of-hours contractors, deliveries, or cleaners, ensuring they are supervised and the building is re-secured once they leave.

Lone Worker Risk Mitigation

Every visit is logged via our digital patrol system, providing an electronic audit trail that proves your site was secured at the exact time required by your insurance policy.

You eliminate the risks associated with Lone Working. Your staff no longer have to be the first in or last out in the dark, reducing the risk of accidents or confrontations.

If an officer discovers a leak, a fire hazard, or a break-in during the lock-up sweep, they are trained to deal with the emergency immediately, potentially saving you thousands in property damage.

Beyond just turning a key, this service is a comprehensive security sweep. When unlocking, our officers disarm alarms and ensure the building is safe for staff entry. During a lock-up, we perform a full internal walkthrough to ensure all windows are closed, non-essential lights/taps are off, fire exits are clear, and no unauthorized persons are left on-site before arming the alarm.

It eliminates the risk associated with Lone Working. Opening or closing a business, often in the dark, can make staff vulnerable to “tiger kidnapping” or opportunistic crime. By using professional security, you fulfil your duty of care by ensuring no employee is ever the first or last person at a potentially isolated site.

If a door lock is broken, a window won’t close, or the alarm system fails, our officer will not leave your premises unprotected. They will immediately contact your emergency lead and remain on-site to provide a physical security presence until the building is made secure or a repair team arrives.

No. Most clients use a secure Keyholding system. Your keys are held in a secure, encrypted safe at our central hub or within a tracked mobile unit. They are only released to the attending officer for their scheduled shift, creating a clear digital audit trail of who had access to your building and when.

Absolutely. We recognize that business needs change. Whether you have an early morning delivery, a late-night inventory count, or a one-off weekend event, our schedules can be adjusted. You simply notify our control room of the time change, and we ensure an officer is there to meet the new requirement.
