Why Crawley Building Sites Are Targeted
Crawley keeps building. New homes at Forge Wood and Kilnwood Vale, warehouse and office schemes on Manor Royal, town centre refurbishment and projects linked to Gatwick Airport all bring plant and materials onto open ground, most of it a short drive from the M23 and A23. That gives thieves a quick route in and out.
The Chartered Institute of Building puts the cost of theft and vandalism to UK construction at over £800 million a year. The usual targets are:
- Plant: excavators, dumpers, telehandlers and generators, often taken by organised groups who have watched the site first.
- Tools: cordless drills, grinders and laser levels left in vans and cabins.
- Copper and cable: first-fix wiring and cable drums, a particular risk on housing schemes during the M&E phase.
- Fuel and materials: diesel from bowsers, timber, insulation and roofing stock.
The risk peaks between 18:00 and 06:00, at weekends and over bank holidays. A theft costs more than the replacement: it can delay the programme, raise insurance premiums and trigger liquidated damages.

How we secure your site
Security that follows your build programme
A building site changes every few weeks. The fence line moves, deliveries fill the compound and high-value stock arrives in stages. We plan cover around those phases, from groundworks to handover.

What Our Construction Site Security Covers
Most Crawley sites need more than one layer of protection. These are the parts we combine into your site's plan:
Out-of-Hours and 24/7 Guarding
A static, SIA-licensed officer is the strongest deterrent and the only option that can act on the spot. We cover the 18:00 to 06:00 night shift, weekends and bank holidays, or provide full 24-hour guarding on larger projects. Officers patrol the perimeter and interior at random intervals so nobody watching can learn a pattern. For static cover away from building sites, see manned guarding in Crawley.
Gate Duties and Access Control
Our officers log visitors, sign contractors in and out, and check deliveries against paperwork before anything is unloaded. That also gives you an accurate headcount if you need to evacuate. On larger projects we can support card or fob turnstiles, visitor pre-registration and ANPR at vehicle gates.
Plant, Tool and Material Protection
We look at where high-value items are kept and how easy they are to reach. That usually means a secure compound for plant, tools and copper, checks on fuel bowsers, and patrol routes focused on stores and containers. We also advise on anti-climb fencing, fence-mounted vibration sensors, concrete blocks at vehicle entrances and PIR floodlights.
CCTV Towers and Remote Monitoring
Rapid-deploy CCTV towers are self-contained units, typically solar-powered with 4G, that can be set up in hours on sites with no fixed power. Pan-tilt-zoom and thermal cameras cover large plots at night, analytics filter out foxes and weather, and operators can issue a live audio challenge through on-site speakers. See also our CCTV monitoring in Crawley.
Mobile Patrols for Smaller Sites
For smaller housing plots, sites in early groundworks or snagging, and contractors with several Crawley sites, marked patrol vehicles visit at scheduled and random times. Each visit includes a perimeter check, confirmation that access points are secure, and a timestamped report with photographs. More on our mobile patrols in Crawley.
Keyholding and Alarm Response
If your cabins, compound or completed units are alarmed, we can hold the keys and respond to out-of-hours activations, so your site manager is not called out at night. This can be added to a guarding or patrol package.
CDM 2015 and Site Induction
CDM 2015 requires principal contractors to prevent unauthorised access, particularly outside working hours. Our officers enforce your induction rules, know your evacuation routes and carry site-specific emergency procedure cards. Night officers work alone, so lone worker check-ins and GPS tracking are built in, and access logs and incident reports form part of your health and safety records.
Reporting Through to Handover
You receive digital reports on patrol times, access, incidents and observations. As the build moves from groundworks through first fix, second fix and handover, we review cover with your site team, adding guards when copper, boilers and fittings arrive and scaling back once the risk drops.
Why Contractors in Crawley Use Quantum
Based in Manor Royal
Our office is on Fleming Way, inside Manor Royal, so site visits, briefings and changes to cover are handled locally.
Site-Ready Officers
Every officer on a construction site holds a current SIA licence and CSCS card, wears full PPE and completes a CDM-compliant site induction.
One Contract, Several Layers
Static guards, mobile patrols, CCTV monitoring, access control and keyholding can all sit under one agreement, so you deal with one supplier instead of several.
Contracts That Fit the Programme
Building projects have an end date. Our construction agreements have no long-term tie-ins, and cover scales up or down as the site moves through each phase.

Frequently Asked Questions
Common questions from contractors and developers about construction site security in Crawley.
How much does construction site security cost in Crawley?
It depends on site size, hours and the mix of services. As a guide, typical UK rates for construction guarding are around £20 to £35 per hour, a 12-hour night shift in Sussex or Surrey typically costs £280 to £420, and 24/7 guarding usually runs at £5,500 to £10,000 a month. See our security guard cost guide. We quote for your site after a free risk assessment.
Do your construction site security officers hold CSCS cards?
Yes. All officers we deploy to construction sites hold current CSCS cards as well as SIA licences, wear full PPE and complete your site induction before their first shift.
How quickly can you put security on a site in Crawley?
We can typically deploy CSCS-carded officers within 24 to 48 hours of instruction. After a break-in, or if a site has been left unsecured, we can often have an officer on site within hours. Contact us with your site details.
Is a mobile patrol enough for a small building site?
Often it is, for smaller plots, early groundworks or snagging. If plant, copper or fit-out stock is on site, an overnight guard, or patrols plus a monitored CCTV tower, gives stronger cover. The risk assessment will show which fits.
Is construction site security a legal requirement?
No law says you must hire guards, but CDM 2015 requires principal contractors to take reasonable steps to prevent unauthorised access, and the Health and Safety at Work Act 1974 sets a duty of care to the public. If an intruder is injured on an unsecured site, the contractor and client can face prosecution. Some insurers also ask for evidence of professional site security as a condition of cover.
