Here at DeepStore we provide unrivalled specialist storage for regulated documents, power industry equipment, pharmaceutical records, and other high‑value or high‑risk assets. Operating from the UK’s largest salt mine in Cheshire, our underground storage environment offers a level of protection and stability that traditional above‑ground facilities simply cannot match.
Why Choose DeepStore for Specialist Storage?
A Unique Underground Environment
DeepStore’s facilities sit 150 metres below ground, an environment naturally shielded from environmental risks such as flooding, UV damage, vermin, and climate change.
This subterranean setting provides consistently stable temperature and humidity conditions ideal for long‑term preservation of sensitive or regulated materials.
Controlled Temperature & Humidity
Our underground location offers a naturally regulated climate, further supported by continuous environmental monitoring. Controlled temperature and humidity help protect materials that may degrade due to heat, moisture, or atmospheric fluctuations—such as pharmaceutical records, technical documents, and precision equipment.
Ultra‑Secure, Compliant Storage
Our secure storage model includes:
- CCTV and vetted staff
- Restricted access areas
- Vehicle‑tracking during transfers
- Alarm and security systems aligned with regulatory requirements for sensitive records
We also operate to ISO 27001 (Information Security), ISO 9001 (Quality Management), and ISO 14001 (Environmental Management), ensuring full compliance for regulated industries including pharmaceuticals and the power sector.
