01 — Service overview
A construction site is an open, changing environment holding a great deal of value. Plant, tools, copper, cabling and raw materials all sit exposed, often behind nothing more than a temporary fence, and the workforce changes daily as trades come and go.
MavCo Security provides premium security services for construction sites, offering a range of customisable options to suit your specific needs. Our personnel are equipped with the latest technology and techniques to deter theft, vandalism and unauthorised access from the first day on site to handover.
For CCTV, equipment tracking and drone surveillance on larger sites, see security for the construction sector.
02 — Why it matters
The direct loss from an overnight theft is rarely the real cost. Replacing stolen plant takes days. A stripped cable run means rework. An insurance claim raises next year's premium. And every one of those delays pushes against a programme that was already tight.
There is a safety dimension too. An open site is a hazard to anyone who wanders onto it, and uncontrolled access puts both your workforce and members of the public at risk — along with the legal exposure that follows.
We work with developers, contractors and site managers to put proportionate, well-documented security in place: enough presence to deter, enough control to account for who is on site, and enough reporting that you can see what happened overnight without having to ask.
03 — What we provide
/01
SIA licensed officers providing a visible, uniformed presence on your site. Our guards manage access, carry out patrols and respond to incidents as they happen rather than reporting them the next morning.
/02
Every entry and exit managed, so only authorised workers, subcontractors and approved visitors get on site — and you have a record of who was there and when.
/03
Continuous boundary protection through scheduled and unannounced patrols, fence-line checks and gate inspections, identifying weak points before anyone else does.
/04
The highest-risk window on any site is the one nobody is watching. We provide dedicated overnight and weekend cover for the hours when your site sits empty.
/05
Machinery, tools and materials protected through regular physical patrols, supervision of storage areas and clear reporting, reducing both opportunistic and organised theft.
/06
Construction carries a heightened fire risk from hot works, flammable stores and temporary structures. Our trained fire marshals can work alongside the security team or as a standalone provision.
/07
Thorough assessments to identify security weaknesses and build a tailored security plan for the site.
/08
Traffic flow managed in and around the site, and close communication with local police.
04 — Why MavCo
/01
Every officer deployed to your site holds a current SIA licence and is fully trained for the role they are placed into.
/02
Days, nights, weekends, shutdown periods and phased handovers — staffing scaled up and down as the build moves through its stages.
/03
Your site gets a plan written around its own layout, access points and risk profile, not a template with your name on the front.
/04
Security, fire marshals, trained workforce and facilities support all come from MavCo Group, so you are dealing with one supplier and one point of contact.
/05
Shift reports, incident logs and patrol records handed over in a form you can file, share with your insurer, or take to a client meeting.
/06
New site, emergency requirement or a supplier who has let you down — talk to us about how quickly we can get officers in place.
