Our Coverage Areas
Click on any area below to learn more about our security services in your location:
Crawley
Crawley is our home. Based right in the centre of Manor Royal Business District, we provide the fastest response times of any security company in the town. Our officers know every neighbourhood — from Three Bridges and Ifield to Maidenbower and Tilgate — and we serve hundreds of commercial, retail, and industrial clients. Whether you need overnight security for a warehouse on Manor Royal or retail officers for County Mall, we are already on the ground.
Horsham
Horsham is one of West Sussex’s most prosperous market towns, with a thriving town centre and a growing business community around Foundry Lane and the Broadbridge Heath retail parks. We provide manned guarding, mobile patrols, CCTV monitoring, and keyholding services to businesses and property managers across Horsham and the surrounding villages. Our teams reach Horsham in approximately 20 minutes from our Crawley base.
East Grinstead
Sitting on the border of West Sussex and Surrey, East Grinstead is a busy market town with a mix of independent retailers, professional services firms, and significant healthcare facilities including the Queen Victoria Hospital. We provide security coverage across the town and surrounding communities, with officers who understand the area’s specific requirements — from protecting high street shops to securing construction sites on the town’s expanding residential developments.
Haywards Heath & Burgess Hill
Haywards Heath and Burgess Hill are two of Mid Sussex’s most important commercial centres. Haywards Heath is a key commuter hub with a growing office sector, while Burgess Hill is undergoing substantial development with the Northern Arc housing project and new business parks. Together, they represent one of the fastest-growing areas in West Sussex, and we provide comprehensive security services to businesses, developers, and property managers across both towns.

Gatwick Airport Area
The Gatwick Airport corridor is one of the most commercially active zones in the South East. Beyond the airport itself, the surrounding area includes major distribution centres, logistics parks, hotels, and office developments that operate around the clock. Our proximity — Manor Royal is less than 10 minutes from the airport perimeter — means we deploy security officers and alarm response teams to any site in the Gatwick area faster than any competitor.

Brighton & Hove
Brighton is a city of contrasts — a major conference destination, a university city, a tourism powerhouse, and the hub of one of the busiest nightlife economies outside London. From The Lanes and North Laine to the seafront and Churchill Square, Brighton presents security challenges that demand experienced, professional teams. We provide the full range of security services across Brighton & Hove, from retail security and event management to construction site protection and corporate security.
Redhill & Reigate
Redhill and Reigate sit just across the Surrey border from our Crawley headquarters, making them among the fastest locations for us to reach outside Crawley itself. Redhill has developed into a significant commercial centre with ongoing town centre regeneration, while Reigate retains its character as a prosperous market town with a high-value retail and residential sector. We provide manned guarding, mobile patrols, CCTV monitoring, and keyholding across both towns.

Guildford
Guildford is Surrey’s county town and one of the most economically important centres in the South East. With the University of Surrey, a busy high street, the Friary Centre, and major employers including Electronic Arts, Guildford generates significant demand for professional security services. We serve businesses, retailers, event organisers, and property managers across Guildford, providing the same quality of SIA-licensed service that our closer clients receive.
