Professional Vault Design, Supply and Installation across Bristol and UK
Established Security Specialists since 1983
Demountable vaults provide the highest level of structural security when a standard domestic or commercial safe is no longer sufficient. Designed for environments where asset protection, compliance and risk mitigation are critical, vault systems deliver reinforced protection far beyond standalone safes.
Vaults are typically specified by the following settings where both capacity and certified resistance to attack are essential.
Financial Institutions
Jewellers
Pharmaceutical Companies
Government
Businesses Safeguarding High-Value or Controlled Assets
Vaults are constructed to meet defined security grades and are fitted with an approved strongroom door to ensure maximum protection. The vaults that Thornhill Security can supplied are available in a range of sizes, wall specifications and configurations. The benefit of a demountable vault is that it can be integrated into your premises with minimal structural disruption.

A demountable vault is a modular, high-security structure designed to meet certified security grades for protecting high-value or controlled assets. It is typically specified where maximum resistance to attack is required. A strongroom may offer enhanced physical protection but is generally designed for broader secure storage applications rather than the highest security classifications. The appropriate solution depends on risk level, insurance requirements and regulatory obligations.
Yes. Demountable vault systems are specifically designed for installation within existing commercial, retail or specialist premises. A detailed site survey is carried out to assess structural suitability, access constraints and installation logistics. This ensures the vault can be installed safely and compliantly without major structural alterations.
Installation timelines vary depending on vault size, security grade and site conditions. Following specification and manufacture, on-site installation is typically completed within a defined and carefully managed programme. A clear schedule is agreed in advance to minimise disruption to business operations.
