Typical clients include retailers who require in-store security guards to prevent shoplifting, licensed premises owners who need door supervisors, event organisers who require stewards to control access to their events and prevent crime, and property developers and other construction firms who require security guards to prevent theft, vandalism or unauthorised entry at construction sites.

Many private security agencies also supply close protection officers (‘bodyguards’) for private clients, particularly high-profile or high net worth individuals. Some also provide consultancy and advice about security precautions in relation to any risk to property or people, or about whether or not to engage a security firm or operative.

Manned guarding, door supervision, close protection and other licensable private security activities are strictly regulated in the UK. Anyone carrying out a licensable activity under a contract for services must be licensed by the Security Industry Authority (SIA) and a licence is also required to employ or supervise licensed security operatives.

In 2010, the Home Office proposed the introduction of a mandatory business licence for private security firms. The proposals were scheduled for implementation by April 2015 and would, assuming personal licences are retained, result in a two-tier licence system. However, at the time of writing (July 2018), the proposals have not yet been implemented.
