SIA Approved Contractor
SIA-licensed security guards in London.
Licensed, BS 7858-vetted security officers for London sites, from an SIA Approved Contractor with a 24/7 operations line.

Licensed and approved
What “SIA approved” means.
Every contracted security officer doing licensable work needs the matching licence from the Security Industry Authority. The SIA’s Approved Contractor Scheme goes further: it assesses the company itself, against a published quality standard.
2015 Security Services Ltd is listed on the SIA Register of Approved Contractors for Security Guarding and Key Holding, so you get licensed officers from a company that is independently assessed. Check our listing on the SIA register.

FAQs
SIA-licensed guards: questions.
What is an SIA-licensed security guard?
A security officer who holds a licence from the Security Industry Authority (SIA) for the work they do. Under the Private Security Industry Act 2001, contracted officers doing licensable work, such as security guarding or door supervision, must hold the matching SIA licence.
What is the difference between SIA licensed and SIA approved?
The licence belongs to the individual officer. The Approved Contractor Scheme (ACS) is the SIA’s voluntary quality standard for security companies. 2015 Security Services Ltd is an SIA Approved Contractor for Security Guarding and Key Holding, and every officer we deploy holds the licence their role requires.
How can I check a guard’s SIA licence?
Ask for the officer’s licence number and check it on the SIA’s public register of licence holders. Our own approval can be checked on the SIA Register of Approved Contractors.
Are your officers vetted?
Yes. Every officer is screened in line with BS 7858 before day one: identity, right to work, employment history and criminal record disclosure.
Which parts of London do you cover?
All 33 London boroughs, from our London head office, with nationwide cover from our offices in Birmingham, Manchester and Glasgow.

How much do security guards cost in London?
