Document Storage Service

CAS provide flexible document storage for all your secure archiving needs across London and the South East of England. We offer tailored storage rates based on your individual requirements. For more than 20 years, CAS has supported public sector, corporate and private clients. Our head office is just four miles from the City of London, backed by our advanced storage centres.

By using CAS’s storage facilities, you can you maximise your office space by reducing the areas required to store and archive records. Storing records off-site can help to achieve lower rents and discounts on insurance premiums. You’ll also have the added peace of mind of dealing with a company with years of experience storing important documents safely and securely for a range of different clients.

Digital document storage system

CAS also provides digital storage solutions through our advanced digitisation and CAS Cloud document management system so that you can back up your paper documents with a fully-searchable digital archive.

We have clients of all sizes, from small- and medium-sized enterprises, right up to NHS trusts and financial services providers. However big or small, CAS works with its clients to find out what they need. That’s why our document storage service, together with our other secure facilities and document management services, are accredited to the highest standards.

Your security is our priority

At CAS we continually strive for the highest levels of security in our document storage service. We have a dedicated fleet of GPS-tracked vehicles to control all document transport to and from storage. Our secure storage facilities have gated perimeter fences, 24/7 security patrols and advanced CCTV. Security staff on the gate require anyone entering the facility to provide identification, and only authorised personnel are admitted. All CAS document-handling and security staff have been checked by the Disclosure and Barring Service (DBS, formerly the Criminal Records Bureau or CRB).

Entry to the warehouses within these facilities is controlled with Suprema BioEntry W2 outdoor vandal-proof fingerprint IP access terminals. BioEntry provides the latest algorithm coupled with powerful quad-core CPU and LFD (live finger detection) technology, with a rugged IP67/IK08 housing. Environmental controls and advanced fire protection systems are fitted throughout.

Document identification which is right up-to-date

If you sign up for our document storage service, you can choose Radio Frequency Identification (RFID) for your legal documents. RFID is one of the most advanced systems to track clients’ documents and provides new levels of accuracy and efficiency far beyond standard barcode management. RFID asset tracking means faster, more cost-effective report generation. It also enables comprehensive audits to be performed in close to real-time with 99.999% accuracy which is essential for practical records storage and compliance regulations (including the strict UK, US and EU financial-sector requirements).

International accreditations to give you peace of mind

Our accreditations and international certifications (ISOs) demonstrate a commitment to excellence in our document storage service. These ISOs prove our compliance with the strictest national, European and international laws.
