Retainagroup Ltd is a leading provider of security marking systems designed to deter theft and aid in the recovery of stolen assets. Since 1982, Retainagroup has led the way in providing vehicle protection solutions. Our mission is simple: To prevent theft, support recovery, and assist law enforcement and insurers every step of the way.

We manufacture and sell innovative and effective technology to mark vehicles, bicycles and assets with proven reduction in theft risk.

The International Security Register (ISR) is a secure database used by police, insurers, and the public to instantly verify and trace marked components and support the recovery of stolen vehicles and other valuable items. Since 1991, the ISR has played a critical role in crime prevention, asset recovery, and successful prosecutions.

Asset marking involves applying a permanent, unique identifier to an item, making it traceable. This acts as a powerful theft deterrent and helps law enforcement recover and return lost or stolen property. Marking also adds credibility to ownership and can support insurance claims.

Retainagroup have a method for marking almost any surface. Therefore, our systems are suitable for many applications, including:

Vehicles (cars, motorcycles, vans, HGVs)
Bicycles
Marine equipment
Agricultural and plant machinery
Tools and construction equipment
Electronics (e.g., laptops, tablets)

Markings are permanent and designed to last the lifetime of the asset. They are tamper-resistant and cannot be removed without visible damage, which helps in both theft deterrence and identification.

If your address or vehicle details change, or if you sell your vehicle, you should update your information promptly with the International Security Register to keep records accurate - you can do this for free. This helps to ensure continued protection and prevents complications if checks are performed in the future. You can update it here https://www.retainagroup.com/registration/vehicle_amendments.html

We work with the automotive industry - OEM, dealerships, vehicle import/export centres, retailers, IT companies, contractors, construction firms, glazing industry, insurers and the police service.

Vehicle windows and/or valuable parts are marked at production plants, import/export centres, or dealerships using a range of methods, including bespoke laser units, stencil & proprietary fluids, electrolysis, and ultra-destruct labels.
Data from marked vehicles is uploaded onto our standalone servers before being transferred into our International Security Register (ISR).

The ISR Stolen & Recovered Vehicle File integrates daily updates from the Law Enforcement Data Service (LEDS), enabling automatic alerts for stolen vehicles and the creation of skeleton records for unmatched entries, with all data retained indefinitely. This powerful system supports police investigations into vehicle cloning and the detection of false plates or stolen parts, such as catalytic converters.

Retainagroup products are used internationally. Please contact Retainagroup directly to confirm availability or request regional support.

Vehicle windows and/or valuable parts are marked at production plants, import/export centres, or dealerships using a range of methods, including bespoke laser units, stencil & proprietary fluids, electrolysis, and ultra-destruct labels. Vehicle details are then registered on the International Security Register (ISR) for 24/7 traceability and verification.

Law enforcement data indicates that both vehicle and asset marking substantially decrease the chances of theft for cars and valuable belongings alike. Stolen vehicles and items are traceable and far more difficult to sell on. Dealers and OEMs benefit from stronger anti-cloning protection, easier verification of replacement parts, and data reporting that helps insurers and authorities track theft trends and recover vehicles faster. Verification through the ISR quickly allows police to confirm ownership. 

We offer a range of methods, including bespoke laser units, stencil & proprietary fluids, electrolysis, and ultra-destruct labels.

If a vehicle has not already been marked at OEM or at the vehicle dealership then the system can be retro fitted either by going to an authorised re-seller, such as Halfords, or contacting us directly.

Markings are permanent and designed to last the lifetime of the asset. They are tamper-resistant and cannot be removed without visible damage, which helps in both theft deterrence and identification.

Both options are available. Marks can be visible to deter theft or applied covertly depending on the application and asset type. Warning labels are also used to supplement etched marks.

Marking an item means it has an identity - which can be checked and verified, making fraud much harder.

Catalytic convertors, high value parts, high risk theft parts and windows are the main parts that are marked. Other parts can also be marked with easy to use kits.

 Typically all the vehicle window glass would be marked but depending on the manufacturer, other high value parts will also be marked such as the catalytic converters, doors, main body areas, and removeable parts including doors, bonnets, boot etc.

Yes - there are regulations and compliance to adhere to.

Vehicles have unique IDs, so recovering them to an owner is possible through tracing via the ISR.

Each vehicle has a unique code, which is stamped on various parts of the vehicle, so that once checked, it can be established that the vehicle is correct and hasn't been passed off as another, or built from multiple vehicles.

The vehicle ID tells you exactly what vehicle it should be.

Only vehicles that are compliant can be given a genuine ID.

Markings are permanent and designed to last the lifetime of the asset. They are tamper-resistant and cannot be removed without visible damage, which helps in both theft deterrence and identification.

Proper record-keeping is essential for compliance with the Companies Act 2006 and for the accurate preparation of statutory financial statements.

The Companies Act 2006 requires companies to keep adequate accounting records to show their financial position and explain their transactions.

Establishes Clear Legal & Liability Protection:

It shields manufacturers, fabricators, and installers from unwarranted injury lawsuits and insurance claims by proving the product was fully compliant before it left the shop floor.

Prevents Fraud and Cheap Counterfeiting

Permanent markings raise the barrier to entry, ensuring that non-compliant glass cannot easily pass off as safety glass. This preserves market prices, protects reputable fabricators from unfair undercutting, and keeps bad actors out of the supply chain.

Guarantees Traceability Throughout the Supply Chain

If a batch of glass experiences a manufacturing defect or failure, the permanent bug allows investigators to trace the glass back to its source, batch, and production plant. This targeted traceability prevents wide-scale product recalls across the whole industry when an issue is localized to a single lot.

Streamlines Inspections & Building Code Sign-Offs

Permanent markings eliminate guesswork. They prevent costly teardowns, project delays, or forced glass replacements at the end of a build, maintaining the industry’s reputation for reliability and efficiency with general contractors and developers.

Prevents Catastrophic On-Site Alterations

A visible safety bug warns field glaziers, glaziers on future renovation jobs, and glass cutters NOT to attempt post-fabrication cuts or modifications on that panel. This protects field workers from violent glass breakage and workplace injuries.

Retainagroup's glass marking systems comply with British Standards BS 6262-4 and Building Regulations Requirement K for the permanent marking of safety glass, ensuring products meet industry and regulatory standards.

There is no extra cost to use the ISR - registration is included in the unit price and verification is free if someone has a code to check.

No - the ISR simply tells you if the ID code on the vehicle matches the vehicle it was registered with. Everything else is confidential.

Only authorised users, such as police, insurers, or Retainagroup staff, can access stored data—strictly for theft recovery or verification purposes. Personal information stored on the ISR is never shared for marketing.

If asked questions about a vehicle ISR operators will only confirm whether the information given to them corresponds to the details held on the ISR.
If there is any doubt about an enquiry, an ISR operator will telephone the registered owner or keeper to clarify the situation.

When police find a marked item, they contact the ISR quoting the code etched on the item. Once the caller’s identification is verified, the ISR operators will confirm the item’s registration status (stolen or not) and may provide contact details to assist recovery.
