Our Security Services in Horsham
Quantum Group provides a full range of security services for businesses across Horsham and the wider district. Our Crawley pages show how each service runs from our Manor Royal base: manned guarding in Crawley, mobile patrols in Crawley, CCTV monitoring in Crawley, construction site security in Crawley and event security in 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 logged and reported, 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 a 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 on the business estates around the town, CCTV monitoring adds a critical layer of protection that works hand-in-hand with physical security measures.
Keyholding and 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.
Retail 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.
Construction Site 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.
Corporate 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.
Event Security
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.
Choosing a local security provider in Horsham
Local Cover
Our headquarters is at Manor Royal in Crawley, and our officers work across the Horsham district. That means a team that knows the area and is briefed on your site, rather than a national firm dispatching from London or Brighton.
Local Knowledge
Our team knows Horsham. We understand how footfall builds around the Carfax, West Street and Swan Walk, how busy the town centre gets on show nights at the Capitol Theatre, and how traffic on the A24 and A264 affects routes into town. That knowledge shapes more effective security planning for your premises.
Accountability
Every officer we deploy in Horsham holds a valid SIA licence and is background-checked before starting. Our mobile patrols are logged and reported, so you can see exactly when your site was visited and what was checked. You always know what you are paying for.
Community Investment
We are a Sussex business based just along the road in Crawley, and Horsham is part of our home patch. Your success is our success, and we approach every client relationship in Horsham with that in mind.

Frequently Asked Questions
Learn more about our security services.
How do you get started with security in Horsham?
We start with a free, no-obligation site survey at your Horsham premises. We look at how the site operates, where it is exposed and when it is most at risk, then recommend the right mix of services, such as manned guarding, mobile patrols or CCTV monitoring, and agree a start date with you. Every officer we supply holds a valid SIA licence.
Are your security officers in Horsham SIA licensed?
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.
What types of businesses do you provide security for in Horsham?
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 security for events in Horsham?
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, 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 is the difference between manned guarding and mobile patrols for Horsham businesses?
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 protection.
Do you provide 24/7 manned guarding in Horsham?
Yes. Our manned guarding can run around the clock, with SIA-licensed officers on site 24/7, or for the hours you choose, such as overnight at a warehouse in Broadbridge Heath or during trading hours on West Street. See manned guarding in Crawley for how the service works from our Manor Royal base.
Can you monitor CCTV for Horsham businesses?
Yes. Our CCTV operatives monitor cameras 24/7, or for the hours you choose, checking each alert on live video and following the response plan agreed for your site. Existing camera systems can often be connected without replacing them. See CCTV monitoring in Crawley for how monitoring is set up for sites across the area.
Do you protect construction sites in Horsham?
Yes. Developments in North Horsham, Broadbridge Heath and the surrounding villages hold plant, tools and materials that are at risk overnight and at weekends. We provide SIA-licensed site guarding, access control at the gate and monitored CCTV. See construction site security in Crawley for how we work with sites and contractors.
Can you provide mobile patrols in Horsham?
Yes. Our mobile patrol officers visit your premises at set or varied times to check doors, windows, gates and fences, and report what they find. Patrols suit sites that do not need a full-time guard, such as offices, industrial units and yards around Horsham. See mobile patrols in Crawley for how patrol visits work.
How much does a security guard cost in Horsham?
Our guide to security guard costs puts standard manned guarding across Crawley, Sussex and Surrey at typically £18 to £25 per hour, with nights, weekends and higher-risk sites costing more. The price for your site depends on the hours, the risk and the number of officers, so we give a transparent quote after a free site survey.
