We’re one of very few security companies in Bedfordshire with accredited status from the industry’s top organisations, guaranteeing complete peace of mind for our residential, commercial and education clients. You can learn more about each of our certifications below:

NSI (National Security Inspectorate)

  • Meeting the technical requirements of the appropriate scheme(s) as well as all of the relevant British Standards.
  • Providing a high level of staff training and supervision to industry best practice standards.
  • Be comprehensively insured to protect customers and staff.
  • Be inspected regularly by NSI auditors to check technical competence with on-site visits and head office management administration.

Safe Contractor

Every company that is Safe Contractor Approved must demonstrate their ongoing commitment to compliance, carrying out high quality workmanship without compromising on safety, sustainability or ethics.

CHAS (The Contractors Health and Safety Assessment Scheme)

Created by experienced health and safety professionals in 1997 to improve health and safety standards across the UK, CHAS accreditation is awarded to contractors who demonstrate they meet the required health and safety standards.
