What Constant Security Services does
Constant Security Services is an independent, family-managed UK security company founded in 1985 and headquartered in Mexborough, South Yorkshire, with a regional North West office in Warrington. It provides a comprehensive portfolio of security services spanning static manned guarding, mobile patrol and keyholding, CCTV remote monitoring, special event security and stewarding, security surveying and consultancy, drone-based surveillance, electronic and physical security system installation, and canine security teams. The company operates across nine named verticals — public sector, manufacturing, education, healthcare, critical infrastructure, sports & leisure, research & technology, distribution and commercial — with dedicated contract managers running bespoke multi-year enterprise contracts for clients such as universities, electricity suppliers, oil and gas operators, racecourses, manufacturing plants and R&D facilities.
Its underlying technology combines human guarding with electronic monitoring systems. Proprietary operational tooling includes a Patrol Evidencing System using proximity points to record on-site patrol activity, Spot-On real-time vehicle tracking to allocate the nearest response unit, and Mobile Response Tablets that transmit operational instructions from the control room to field units. CCTV remote monitoring is delivered through the third-party Immix Platform for event-based surveillance, augmented with Calipsa AI-powered false alarm filtering. Drone security is delivered in partnership with Evolution Yorkshire rather than built in-house.
The business model is a direct enterprise field-sales motion selling bespoke, quote-based professional and managed security services on multi-year contracts. Revenue streams are diversified across professional services (guarding, mobile, events, surveying, canine, drone) and managed/hardware services (CCTV remote monitoring, electronic and physical system installation with leasing options). Pricing is not publicly disclosed and is tailored to scope, sector and contract terms. The company holds NSI Guarding Gold with UKAS Product Certification, SIA Approved Contractor status within the top 5% of scheme scores, ISO 9001:2015, Cyber Essentials and a comprehensive suite of British Standards certifications.
