How to Sell a Security Services Company
Security services businesses — guarding, CCTV, access control, and alarm monitoring — achieve EBITDA multiples of 3.5–5.5× from FM groups, national security companies, and individual buyers. SIA-approved contractor status and individual SIA-licensed guard workforces create the regulatory credentials that underpin the business. Recurring alarm monitoring contracts are the most valuable revenue component, providing predictable monthly income from an installed base.
Who Buys Security Services Businesses?
National security groups (Mitie Security, G4S, Securitas, Alarm Company Group) seeking regional guarding capacity or monitoring capability. FM companies internalising manned guarding. Individual security industry professionals seeking business ownership. Electronic security (CCTV, access control, alarms) installers and monitoring companies.
What Drives Value in a Security Services Sale
SIA Approved Contractor Scheme (ACS) membership — a prerequisite for major commercial and public sector contracts. Alarm monitoring subscriber base (recurring monthly income per premise monitored) creates predictable revenue. Long-term guarding contracts with commercial or public sector clients. Lone worker, close protection, or specialist guarding capability commands higher rates. NSI Gold or SSAIB certification for electronic security businesses.
Common Due Diligence Concerns
Individual SIA licences are held by guards — new owner must ensure continuous licence compliance for all deployed staff. ACS reapplication may be required under the new ownership entity. DBS and vetting record documentation for all guarding staff. Public liability and employers' liability insurance claims history reviewed. TUPE considerations for guarding staff deployed on client sites.
Typical Sale Timeline
A security services business typically takes 4–8 months to sell from preparation to completion.
