Our Security Services in Crawley
Quantum Group provides comprehensive security solutions across Crawley:
Manned Guarding
Our manned guarding service places trained, uniformed security officers at your Horsham premises. Whether you need a permanent security presence at a commercial building near Horsham station, a night-shift guard for a warehouse in Broadbridge Heath, or front-of-house security for a retail unit on West Street, our officers provide a visible deterrent and a professional first point of contact.
Manned guards are particularly effective for businesses in Horsham town centre where footfall is high and the risk of shoplifting, antisocial behaviour, or unauthorised access requires a constant, vigilant presence.
Mobile Patrols
For businesses that need regular security checks without the cost of a full-time on-site guard, our mobile patrol service provides the ideal solution. Our patrol vehicles cover Horsham and its surrounding areas including Roffey, North Horsham, Warnham, Southwater, and Billingshurst, conducting scheduled and randomised checks on your property throughout the day and night.
Each patrol is GPS-tracked and logged, giving you full transparency over when your site was visited and what was inspected. This service is especially popular with landlords managing multiple properties, retail parks, and industrial units across the Horsham district.
CCTV Monitoring
Modern security demands modern technology. Our CCTV monitoring service connects your Horsham premises to our 24/7 monitoring centre, where trained operators watch live feeds and respond immediately to any suspicious activity. We work with existing camera systems or can advise on new installations to ensure complete coverage of your site.
For businesses around Swan Walk shopping centre, along the Bishopric, or in the expanding commercial areas near Christ’s Hospital, CCTV monitoring adds a critical layer of protection that works hand-in-hand with physical security measures.
Alarm Response
When your burglar alarm activates at 3am, the last thing you want is to drive across Horsham in the dark to investigate. Our keyholding service means we hold a secure set of your keys and respond on your behalf. Combined with our alarm monitoring service, we can have an SIA-licensed officer at your Horsham premises within minutes of an activation.
This service is invaluable for business owners who live outside the Horsham area, or for property managers responsible for multiple sites across West Sussex. It gives you peace of mind knowing that every alarm is investigated promptly and professionally.
Construction Site Security
Horsham’s retail sector is a cornerstone of the local economy. From independent boutiques on the Carfax to national chains in Swan Walk, shops face ongoing challenges from shoplifting, staff safety concerns, and antisocial behaviour. Our retail security officers are trained specifically for the retail environment, providing a reassuring presence for staff and customers alike while actively deterring theft.
We understand the balance between maintaining a welcoming shopping experience and ensuring robust loss prevention. Our retail security teams in Horsham are skilled in conflict de-escalation, customer interaction, and evidence gathering to support prosecutions where necessary.
Retail Security
Horsham is experiencing significant development, with new housing and commercial projects underway across North Horsham, Broadbridge Heath, and the surrounding villages. Construction sites are prime targets for theft of materials, plant machinery, and tools, as well as vandalism and trespassing.
Our construction site security service provides manned guards, mobile patrols, and CCTV solutions tailored to the unique demands of building sites. We work with developers, main contractors, and project managers to ensure sites remain secure throughout every phase of construction, from groundworks to handover.
Event Security
For offices and corporate premises in Horsham, our corporate security service delivers discreet, professional protection. This includes reception security, access control management, visitor screening, and executive protection. We serve businesses of all sizes, from SMEs in serviced offices to larger firms with dedicated Horsham headquarters.
Door Supervision
Horsham has a lively events scene. From live performances at the Capitol Theatre and outdoor events in Horsham Park to private functions at local venues, every gathering requires a proper security plan. Our event security team handles crowd management, access control, VIP protection, and emergency response planning.
We have experience providing security for public festivals, corporate conferences, charity events, and private celebrations across Horsham and West Sussex. Every event engagement begins with a thorough risk assessment to identify potential threats and ensure a safe, enjoyable experience for all attendees.

How quickly can you respond to incidents in Crawley?
Because our headquarters is located at Crawley Business Quarter, just 15 minutes from Horsham town centre via the A264, we can deploy security officers rapidly. For planned engagements, we typically have officers on-site within 24 to 48 hours of contract agreement. For emergency or urgent requirements, we can often respond the same day.

What qualifications do your security officers hold?
Yes, without exception. Every security officer we deploy in Horsham holds a valid Security Industry Authority (SIA) licence, which is a legal requirement for anyone carrying out licensable security activities in the UK. Beyond licensing, all our officers undergo thorough background checks, reference verification, and receive ongoing professional training in areas including conflict management, first aid, fire safety, and customer service.
Do you provide security for construction sites in Crawley?
We provide security services in Horsham for a wide range of sectors. This includes retail shops and shopping centres, offices and corporate premises, construction and development sites, warehouses and industrial units, pubs, restaurants, and hospitality venues, schools and educational facilities, healthcare premises, residential estates, and public events. Whether you are a sole trader with a single shop on the Carfax or a national developer building hundreds of homes in North Horsham, we have the experience and resources to protect your interests.
Can you provide 24/7 security coverage?
Absolutely. Our event security service caters for both one-off and recurring events in Horsham. We have provided security for concerts and performances at the Capitol Theatre, outdoor gatherings in Horsham Park, corporate conferences at The Forum Horsham, charity fundraisers, private parties, and sporting events. Every event engagement includes a full risk assessment and a detailed security plan tailored to the specific venue, expected attendance, and nature of the event.
What areas around Crawley do you cover?
Manned guarding places a dedicated security officer at your premises for a set period, providing a continuous, visible security presence. This is ideal for sites requiring constant monitoring, such as retail stores, reception areas, or high-risk locations. Mobile patrols, on the other hand, involve our patrol vehicles visiting your premises at scheduled or random intervals to conduct external and internal checks. Patrols are a cost-effective option for businesses that need regular security oversight without the expense of a full-time guard. Many of our Horsham clients combine both services for comprehensive, round-the-clock protection.
