Best security device for motorbike insurance is a question every UK rider considers when seeing the impact of security on the premium. The honest answer is that no single device delivers the largest premium reduction. The combination of an approved chain and lock, a ground anchor, a disc lock for daytime use, an alarm and a tracker produces the largest cumulative effect. Sold Secure and Thatcham Research are the two recognised approval bodies in the UK, and insurers usually require devices meeting their standards as a condition of cover for higher-value motorcycles.
Best security device for motorbike insurance and the recognised standards
Best security device for motorbike insurance starts with the recognised approval standards. Sold Secure is the independent testing body for physical security devices including chains, locks, ground anchors and disc locks. The Sold Secure rating ranges from Bronze at the lowest to Diamond at the highest, with Powered Cycle Diamond used specifically for motorcycle products. Thatcham Research operates a parallel approval system for vehicle-based security including alarms, immobilisers and trackers.
Most UK motorcycle insurers require security devices to meet either Sold Secure or Thatcham approval as a condition of cover. The exact requirement varies by insurer and by the value of the motorcycle. Lower-value bikes may only need a basic Sold Secure Silver chain, while higher-value bikes often require Diamond rated chains plus a ground anchor and a tracker. Reading the policy schedule for the specific security requirements is essential before relying on cover.
The Police Service approved product list draws on Sold Secure and Thatcham approvals. Devices on the list are recommended by UK police forces because they have been tested against the typical attack methods used in motorcycle theft. The Metropolitan Police, the National Police Chiefs' Council and other police bodies promote these standards as part of crime prevention work.
Motorbike lock insurance discount and chain selection
Motorbike lock insurance discount is one of the most common discount categories on UK motorcycle insurance. Insurers typically offer reductions of 5 to 15 per cent for using an approved chain and lock when the motorcycle is left unattended away from home. The chain must be passed through a fixed point such as a Sold Secure ground anchor or a substantial street furniture point such as a lamp post or bicycle stand.
Chain selection is a balance between security level and practicality. Higher Sold Secure ratings use thicker link material and more robust locks but weigh more and cost more to carry. A Sold Secure Diamond rated chain typically weighs 4 to 6 kilograms and costs £80 to £200. For daily commuter use this weight is significant, and many riders compromise with a Sold Secure Gold chain at lower weight and cost. Insurers usually accept Sold Secure Gold for mid-range motorcycles but may require Diamond for higher-value bikes.
Lock selection matters as much as chain selection. The lock is usually the weakest point of the chain assembly and is the target for most attack methods. Hardened steel locks with anti-pick cylinders meet the relevant Sold Secure standards. Some riders use two locks at either end of the chain to slow down an attacker, although this approach adds weight and is not always practical.
Approved bike security devices UK - ground anchors and disc locks
Ground anchors are the most effective overnight security device for home storage. A Sold Secure Diamond rated ground anchor cemented into the floor of a garage or driveway provides a fixed point for the chain, removing the risk of an attacker simply lifting the motorcycle off the chain. Installation costs typically £100 to £300 including the anchor itself, with professional fitting recommended for security and structural reasons.
Disc locks are useful for daytime use and short stops. The lock fits through the front or rear brake disc and prevents the wheel from turning. Disc locks are usually paired with a chain when the motorcycle is left for longer periods, but a disc lock alone can deter opportunistic theft for short stops. Sold Secure ratings apply to disc locks in the same way as to chains. Disc lock reminder cables are essential to prevent the rider attempting to ride off with the lock still fitted.
Combination products such as chain plus disc lock kits, ground anchor with chain bundles, and lockable storage boxes for chains all save costs against buying components separately. Specialist motorcycle accessory shops and online retailers stock the full range, and the leading specialist insurers often have affinity arrangements with security brands that produce discounts for policyholders.
Alarms, immobilisers and Thatcham approved trackers
Alarms and immobilisers form the electronic side of motorcycle security. Most modern motorcycles include factory-fitted immobilisers as standard, which prevent the engine starting without the correct transponder key. Aftermarket alarms add audible deterrents and movement sensors that activate when the bike is disturbed. Thatcham category 1 ratings cover alarm-and-immobiliser combinations, while category 2 covers immobiliser-only devices.
Trackers operate on a different principle. Once a motorcycle is stolen and reported, the tracker reports its location to a monitoring centre, which works with police to recover the bike. Thatcham category 5 and category 6 are the recognised standards for vehicle trackers, with category 5 including driver identification and category 6 covering basic tracking without driver ID. Trackers can reduce premiums by 10 to 20 per cent on some insurers, and recovery rates for tracked motorcycles are materially higher than for untracked bikes.
The leading UK tracker brands include Datatool, Tracker, Roadhawk and BikeTrac. Annual subscription fees apply, typically £100 to £200 a year, in addition to the upfront fitting cost. For higher-value motorcycles the subscription is usually recovered in insurance savings within the first year. For lower-value bikes the calculation is less favourable, although the recovery rate benefit alone may justify the cost.
Storage location and the combined effect of multiple devices
Storage location combined with security devices produces the largest single discount on theft risk. A motorcycle stored in a locked garage with a ground anchor, an approved chain and lock, an alarm and a tracker presents a much lower theft risk than one parked on the street with only a basic chain. Insurers price this combination explicitly, and the premium difference between worst case and best case storage can be substantial.
For riders without garage access, secure compound storage in cities offers a middle ground. Several UK cities have motorcycle storage businesses offering covered or compound storage with CCTV and access controls. The cost is typically £50 to £200 a month depending on location and facilities. The premium saving over street parking is often comparable to the compound cost, particularly for higher-value bikes in central London or other high-theft postcodes.
Insurance industry data from the National Motorcycle Council and the Motorcycle Industry Association consistently shows that theft is the single largest claim category for motorcycle insurance. Investing in approved security and secure storage is the most reliable way to bring down the premium and to reduce the personal risk of losing the motorcycle. Combined with no claims discount built over years, the savings can be significant across the life of motorcycle ownership. Riders should review their security setup at each policy renewal to confirm devices meet current insurer requirements.

Frequently asked questions
What is the best motorbike security device for insurance discounts?
The combination of an approved chain and lock, a ground anchor, an alarm and a tracker produces the largest cumulative discount. No single device delivers the biggest reduction. Sold Secure and Thatcham approved devices are required by most insurers, with Diamond ratings increasingly expected for higher-value motorcycles in higher-risk postcodes.
Do Sold Secure chains reduce motorcycle insurance premiums?
Yes. Most UK motorcycle insurers offer discounts of 5 to 15 per cent for using an approved chain and lock. Sold Secure Diamond is the highest rating and is increasingly required by insurers for higher-value bikes. Sold Secure Gold is usually accepted for mid-range motorcycles, while Silver may be acceptable for lower-value bikes.
Are motorcycle trackers worth the cost?
For higher-value motorcycles yes. Trackers can reduce premiums by 10 to 20 per cent on some insurers, and recovery rates for tracked motorcycles are materially higher than for untracked bikes. Annual subscription fees of £100 to £200 are typical. For lower-value bikes the calculation is less favourable, although the recovery rate benefit alone may justify the cost.
What is a Thatcham category 5 tracker?
Thatcham category 5 is the recognised standard for vehicle trackers including driver identification. The tracker reports the motorcycle's location to a monitoring centre if it is stolen, and the driver identification feature confirms that the rider is authorised. Category 6 is a similar tracking standard without driver identification. Insurers usually specify the category required for higher-value motorcycles.
Do I need a ground anchor for motorcycle insurance?
Many insurers require a ground anchor for higher-value motorcycles stored at home. The anchor is cemented into the floor of a garage or driveway and provides a fixed point for the chain. Sold Secure Diamond rated ground anchors are typically required for newer or premium motorcycles. Lower-value bikes may not need an anchor but cover terms vary by insurer.
How much can I save with motorcycle security devices?
Combined savings from approved chains, locks, ground anchors, alarms and trackers can reduce premiums by 20 to 40 per cent across the full security package. Storage location combined with security devices produces the largest single discount on theft risk, with garaged bikes attracting much lower premiums than street-parked ones.
