A safe is one of the most reliable ways to protect your most valuable possessions, from jewellery and cash to important documents and digital data. However, choosing the wrong safe can leave your valuables vulnerable. Keys4U Locksmith explains everything you need to know to make the right choice.
Understand Security Ratings
Safes are rated by the level of protection they offer against attack. In the UK, the main ratings to look for are:
- EN 14450 S1 and S2: Standard security for home and light commercial use
- EN 1143-1 Grade 0 to Grade VI: Higher security grades for valuables and cash storage, with insurance-approved ratings
- NT Fire 017: Fire resistance ratings indicating how long documents remain protected in a fire
For home jewellery and modest cash amounts, an S2-rated safe is usually sufficient. For larger cash holdings or high-value items, choose a Grade I or higher safe that meets your insurer's requirements.
Size and Capacity
Consider not just what you need to store now, but what you may need in the future. Common safe sizes range from compact A4 document safes to large floor-standing models. Remember that the internal dimensions are always smaller than the external dimensions due to the protective walls.
A safe that is too small becomes frustrating. One that is too large may be difficult to conceal effectively. Strike a balance based on your current and anticipated storage needs.
Lock Types
Safes come with various locking mechanisms:
- Key locks: Simple and reliable but vulnerable if keys are lost or stolen
- Digital keypads: Convenient and allow multiple user codes, but require battery replacement
- Biometric fingerprint: High-tech and fast, though more expensive
- Combination dial: Traditional, battery-free and extremely reliable
Many high-quality safes offer dual locking systems, combining a key with a digital code for added security.
Fire and Water Protection
If you plan to store documents, digital media or photographs, fire resistance is essential. Document safes typically offer 30 to 60 minutes of protection. For digital media such as USB drives and hard drives, you need a specialised data safe with lower internal temperature limits.
Water resistance is valuable in flood-prone areas or if the safe may be exposed to firefighting efforts.
Installation Matters
A safe is only as secure as its installation. Floor-mounted safes should be bolted through the base into solid concrete. Wall-mounted safes need secure anchoring into brick or blockwork, not timber stud walls. A free-standing safe that is not bolted down can simply be carried away.
Professional installation by a qualified locksmith ensures your safe is properly secured and positioned for both security and accessibility.
