About us
A UK security provider with 25+ years of experience, SIA Approved Contractor status and a simple promise: our team is your team.

Our story
Having successfully attained Approved Contractor status with the Security Industry Authority (SIA) in 2020, Marvellous Security Services experienced considerable growth. Our services — particularly supporting some of the world’s and the UK’s largest security providers — became very much sought after.
In 2022 we opened a second office in Glasgow to deal with increased demand and to enhance our operational options nationally. We now operate from offices in Manchester, Glasgow, Nottingham, Belfast and London, with regional offices in Grantham and Widnes.
Marvellous Security Services Limited is constantly striving to raise standards within the security industry. As a business, we are always looking at new ways to be innovative and creative, helping us remain competitive in a very fast-paced sector.
