SEVERNSIDE SECURITY LTD

What SEVERNSIDE SECURITY LTD does

Severnside Security Ltd is a Gloucester-headquartered, privately-held UK fire and security systems integrator founded in 1992, operating across South West England with nationwide delivery. The company designs, installs, and maintains intruder alarms, CCTV (HD and IP), access control, door entry, warden call, automatic doors, automated gates and barriers, speed gates, and communal security doors, together with BAFE SP203-1 accredited fire detection and life safety systems. It complements this core hardware portfolio with proprietary-branded technology offerings — InsideOut Technology, Smart Home, and Smart Business — that layer intelligent automation and analytics on top of physical security deployments, including UniFi-based centralized network management.

The business serves a broad mix of commercial, corporate, education, government, healthcare, housing association, leisure and hospitality, retail, and private/residential clients. Notable institutional references include NHS, Gloucestershire County Council, Gloucestershire Constabulary, Knight Frank, Bromford Housing, Sanctuary, Riverside, Curo, Sue Ryder, and Watch House. It has documented service to over 1,000 UK customers and a 30+ year operating history.

The go-to-market is consultative direct sales with no public pricing; projects are quoted on a bespoke basis following free site consultations, supported by localized SEO across multiple UK regions. Revenue is generated from one-time installation projects supplemented by recurring maintenance and servicing contracts, with the fire-safety line specifically structured around accredited installation and ongoing compliance. Industry accreditations — BAFE SP203-1, SSAIB, ISO 9001, SafeContractor, ConstructionLine, DHF, SSIP, CQS, and Living Wage Employer — underpin eligibility for regulated and public-sector work. The company appears to operate as an owner-managed SME with no disclosed external funding, M&A, or institutional ownership.

Direct peers

• ADT UK: ADT UK is one of the largest national providers of intruder alarms, CCTV, access control and 24/7 monitored security. Directly comparable to Severnside on product scope (intruder alarms, CCTV, smart-home integration, maintenance contracts), but operates at much greater scale and brand recognition across the UK.
• Banham Group: Banham is a long-established London-based security installer offering intruder alarms, CCTV, access control, door entry, locksmith services and locks. Directly comparable to Severnside's integrated design-install-maintain model with strong credentials in residential and high-end commercial security, including high-net-worth clients similar to Severnside's Private Clients segment.
• Verisure UK: Verisure UK specialises in monitored intruder alarms and smart-home security for residential and small-business customers, with professional installation and 24/7 monitoring. Closely comparable to Severnside's residential/homeowner segment on technology (connected alarms, mobile apps, monitoring) and GTM (consultative direct sales).
• ERA Home Security: ERA is a UK-based provider of home security products and professionally installed intruder alarm and CCTV systems. Comparable to Severnside's residential/homeowner segment with a similar focus on professionally installed, monitored smart security, though ERA is more product-led.

Emerging players

• Ring (Amazon): Ring offers DIY-installed video doorbells, smart cameras and home security with optional professional monitoring. Not a direct installer competitor, but it represents the smart-home/DIY trend that competes with Severnside's residential intruder alarm and CCTV offering on price and ease of installation.

Others

• CSL Group: CSL Group is a UK provider of secure connectivity (dual-path signalling, IoT/M2M) for fire and security systems, including for intruder alarms and CCTV. Adjacent enabler to Severnside's monitoring and alarm signalling infrastructure rather than a direct competitor.
• Texecom: Texecom is a UK designer and manufacturer of professional intruder alarm panels and detectors. Enabler/supplier to installers like Severnside rather than a competitor; its products are commonly integrated into UK commercial and residential security installations.
• Pyronix: Pyronix is a UK-based manufacturer of intruder alarm detectors, panels and wireless security products (now part of Hikvision). Adjacent supplier relationship to Severnside, which integrates third-party alarm hardware rather than manufacturing its own.

Broad incumbents

• Securitas UK: Securitas is a global security services giant offering manned guarding, electronic security, fire & safety and remote monitoring. Broader and far larger than Severnside, but its UK electronic security division (post-ADT acquisition) directly overlaps with Severnside's CCTV, access control and intruder alarm offerings.
• G4S / Allied Universal UK: G4S (now part of Allied Universal) provides manned guarding, facilities management, electronic security systems and monitoring across the UK. Overlaps with Severnside on integrated security installations and BAFE-accredited fire safety, though it operates at far greater scale across multiple security verticals.
