Insurance Approved Safes – Approval from AiS (Assurance of Insurance Surveyors) confirms that these safes have been independently attack tested by recognised testing centres like BRE and ECBS. Insurance companies in the UK approve safes with the AiS label as testing from these centres are of the highest standards. AiS labelled safes are accepted by all UK Insurance companies as they represent an accurate reflection of the level of attack these safes can withstand. Indicated by a cash or valuable rating, this terminology relates back to the value of asset being stored in the safe.
