Division 80 of the UK SIC 2007 list. It holds 2 codes, listed in full below with the number of active UK companies filed under each.
Division 80 holds two very different populations. Code 80100, private security activities, covers manned guarding, door supervision and close protection. It is a labour-heavy trade where contracts and licensed staff are the whole business. Code 80200 covers security systems services. Those firms install and monitor alarms, CCTV and access control, and they behave more like specialist electrical contractors. The two buy in completely different ways, so they should rarely get the same emails. Both groups contain many small subcontractors built around one client.
Guarding firms under 80100 attract workforce management software vendors, payroll and invoice finance providers, and insurers. SIA licensing consultants chase new incorporations before the first contract lands. Systems installers under 80200 draw a different set: wholesale equipment distributors, monitoring station partners, and the accreditation bodies whose inspectorate badges unlock commercial work. In both camps a big contract win forces sudden hiring or stock buying. So visible growth is the strongest buying signal here. Filing deadlines point to thinly-run firms that need back-office help.
No. SIC codes are self-declared at Companies House and nobody vets them. Security Industry Authority licensing applies to individuals doing licensable roles, such as guarding and door supervision. The voluntary Approved Contractor Scheme applies to businesses. A company can sit under 80100 and hold no licences at all. Check SIA status separately from the register.
Use 80200, security systems service activities. It is the standard fit for installing and monitoring alarms, CCTV and access control. Some installers also register an electrical installation code from division 43. Companies House permits that, since each company may hold up to 4 codes. Set codes at incorporation and change them on the confirmation statement (CS01). No approval is needed either way.
