A home safe serves two distinct purposes: protecting valuables from theft and, where fire-rated, protecting documents and data media from fire damage. Choosing the right safe requires understanding how safes are graded for both threats, what your insurer actually requires, and the practical considerations of weight, fitting, and access.
The UK safe market uses European standards for both burglary resistance and fire resistance. Understanding the grading system before purchasing prevents the common mistake of buying an unrated or insufficiently rated safe that your insurer will not recognise.
Insurance Cash Ratings
UK insurers express safe capacity in terms of a cash rating — the maximum value of cash the safe is approved to protect. Jewellery and other valuables are typically covered at a multiple of the cash rating, most commonly 10×.
Example: a safe with a cash rating of £1,000 would be approved by most insurers to protect up to £10,000 worth of jewellery.
Cash ratings are set by the insurer (not the standard) and depend on the safe’s tested resistance to burglary attack. Common insurer cash ratings for domestic safes:
| Insurer cash rating | Typical safe grade | Approximate minimum EN 1143-1 grade |
|---|---|---|
| £1,000 | Basic / ungraded (some insurers) | None (entry-level) |
| £2,500 | Tested to EN 1143-1 Grade 0 | Grade 0 |
| £6,000 | EN 1143-1 Grade I | Grade I |
| £10,000 | EN 1143-1 Grade II | Grade II |
| £17,500+ | EN 1143-1 Grade III+ | Grade III |
Always check with your specific insurer before purchasing — cash ratings and acceptable grades vary between policies. Some budget home insurance policies do not specify a grade at all; others require EN 1143-1 minimum Grade I for any claim on valuables stored in a safe.
EN 1143-1 Burglary Resistance Grades
EN 1143-1 is the European standard for burglary-resistant safes. Grades run from 0 to VI, each requiring progressively greater resistance to attack by increasingly capable burglary tools tested over defined time periods:
| Grade | Resistance units (RU) | Typical cash rating (UK insurer) | Typical weight | Typical cost |
|---|---|---|---|---|
| Grade 0 | 30 RU | £2,000–£4,000 | 30–80 kg | £150–£500 |
| Grade I | 50 RU | £6,000–£8,000 | 80–200 kg | £400–£1,200 |
| Grade II | 80 RU | £10,000–£15,000 | 150–350 kg | £800–£2,500 |
| Grade III | 120 RU | £17,500–£35,000 | 250–500 kg | £1,500–£5,000+ |
| Grade IV–VI | 180–1,000 RU | Commercial/high-value | 400 kg–1+ tonne | £5,000–£50,000+ |
Grades IV and above are primarily commercial. For domestic use, Grade 0 or Grade I meets the requirements of the vast majority of UK home insurance policies.
Fire Ratings
Burglary resistance and fire resistance are separate properties — a safe that is excellent at resisting attack may provide no fire protection, and vice versa. Two standards apply:
EN 1047-1 — the higher standard for data media (hard drives, USB drives, film) as well as documents. Specifies performance in a fire reaching 1,000°C, including survival of the cool-down phase. Rated in time periods: 30, 60, or 120 minutes. The internal temperature of a safe tested to EN 1047-1 must not exceed 50°C and humidity must remain below 85% throughout the test.
EN 15659 (LFS 30P) — the lighter standard for documents only. Internal temperature must not exceed 170°C (the ignition temperature of paper) for the rated period. Common ratings are 30 or 60 minutes at 843°C. Less protective than EN 1047-1 but more affordable and available in lighter safe bodies.
No fire rating — most burglary-rated safes, particularly small domestic models, have no meaningful fire resistance. The heavy steel construction provides some incidental protection but will not preserve paper documents or electronics in a significant house fire.
If fire protection is a priority (for passports, deeds, hard drives), specify the fire rating separately from the burglary grade and confirm both are present in any safe you purchase.
Types of Safe
Freestanding home safe — the most common type. Ranges from small entry-level units (10–20 kg, ungraded or Grade 0) to large Grade I–II units (80–200+ kg). Smaller units must be bolted to the floor or wall; larger units resist attack by virtue of their own weight. Typically floor-standing.
Floor safe — set into a concrete floor or built into a floor void and concealed by carpet or floorboards. Extremely difficult to remove; access is through the top. Less useful for frequent access but excellent for long-term storage of documents and valuables. Requires structural floor work to install; typically fitted by a locksmith or safe engineer.
Wall safe — fitted into a stud wall or masonry wall and concealed behind a mirror or picture. Smaller cavity limits size and grade — most wall safes are ungraded or Grade 0 at best. Useful for everyday valuables (passports, cash) but not appropriate for high-value items or fire protection.
Document safe (data safe) — a fire-rated safe optimised for document and data storage rather than burglary resistance. Often rated to EN 15659 or EN 1047-1. May be a filing-cabinet form factor. Burglary rating is typically low (Grade 0 at best).
Gun cabinet / firearms cabinet — a legal requirement under UK firearms licensing. A steel cabinet fixed to a wall and conforming to the dimensions and specifications set out in the Home Office Guide on Firearms Licensing Law. Not a safe in the burglary-resistance sense — purpose-built to deny casual access and meet police requirements. Cost: £100–£400 supply, fixed by a registered firearms dealer or approved fitter.
Portable travel safe — small, lightweight (1–5 kg), with a cable to anchor to a fixed point. Provides nominal security for a hotel room or short-term situation. Not insurance-rated for home use; no meaningful burglary resistance.
Locking Mechanisms
| Mechanism | Typical use | Cost premium | Key risks |
|---|---|---|---|
| Key lock | Entry-level, gun cabinets | Low (included) | Key loss; picking |
| Combination dial | Mid-range, classic | Low–medium | Manipulation; user forgetting combination |
| Electronic keypad | Most common mid-range domestic | Low–medium | Battery failure; electronic attack on cheap units |
| Biometric (fingerprint) | Premium domestic | Medium–high | Sensor failure; false rejection in cold/wet conditions |
| Time-delay lock | Commercial, Grade III+ | High | Inconvenient for routine access |
Electronic keypad locks are the most practical for home use — fast access, no key to lose, and battery low-warning indicators are standard on quality units. Change the code on installation and periodically thereafter. Most units have an emergency key override — store this key separately and securely.
Biometric locks add convenience but introduce additional failure modes; always choose a model with a keypad or key backup.
Fixing Requirements
Most insurers require that any free-standing safe be bolted to the floor or wall as a condition of cover. A safe that can be carried away and attacked at leisure provides far less protection than one that is fixed.
Manufacturer-supplied anchor bolts should be used through the pre-drilled base fixings into a concrete floor or solid masonry wall. Stud partitions are not adequate for fixing a safe — the fixings will pull through the plasterboard under attack.
Fixing kits are usually included with the safe; a locksmith or safe engineer can install and anchor a safe for £80–£200 depending on the fixing substrate.
Large Grade I–II safes (150+ kg) resist removal by weight alone but should still be fixed where possible.

Practical Advice
Check your insurer’s requirements before purchasing — the specific grade or cash rating they require should be in your policy schedule or confirmed in writing. A safe that is one grade below the insurer’s requirement will not support a claim.
For most UK homes, a Grade 0 or Grade I electronic keypad safe bolted to a concrete floor, costing £150–£600, will meet insurer requirements and provide adequate protection. If you also want fire protection for documents, purchase a separate document safe or specify a combined burglary and fire-rated unit — confirm both ratings are independently certified before buying.
Professional installation by a locksmith or safe engineer adds £80–£200 but ensures correct anchoring and proper operation, which matters when you need to access the safe in an emergency.
