What it is

A full-time guarding business that provides static guards, patrols and key holding for sites and premises, often overnight or at weekends. You manage rotas, clients and compliance while a small team covers shifts.

Your first three steps

  1. Get your own SIA licence and check the SIA website for business approval options such as the Approved Contractor Scheme
  2. Get quotes for public liability and employer's liability insurance, and set up as a sole trader or limited company
  3. Contact local contractors, letting agents and property managers to offer a trial contract or short cover period
Who pays

Building contractors, landlords and property managers, retail units, warehouses, car dealerships and owners of empty or vacant buildings.

How it makes money

Contracts are priced per guard hour or per patrol visit, often with a monthly retainer. Regular multi-month contracts give steadier income than one-off jobs.

Skills that help
  • Sales and building relationships with businesses
  • Rota planning and managing people
  • Record keeping and incident reporting
  • Reliable and trustworthy
Watch out for
  • All guards on contract work generally need the right SIA licence, so check licences before every shift
  • Check which business-level SIA rules or approvals apply in your part of the UK, as these can change
  • Employer's liability insurance once you hire, plus employment rules such as the minimum wage, holiday pay and working time
  • Lone night work carries risk, so plan check-in procedures and safe working
  • Large clients often pay late and expect approved-contractor status, so keep enough cash to cover wages
