Based in Hertfordshire, (on the M1, M25, A1 corridors), we are conveniently situated to cover London, Essex, Bedfordshire, Kent, Surrey, Middlesex, Cambridgeshire Berkshire and Buckinghamshire. However, it is not uncommon for us to be on assignments in the North or further South. Recent assignments have been performed abroad with distance proving to be no object. Unlike most companies of this nature we employ our own Operatives on a full time basis rather than subcontract the work out to others in the field.

Please feel free to browse the site and to either telephone 0800 0439 324 or email admin@securityun-limited.com with your enquiry.

Normally any guidance as to what service you require is given free of charge.
