Thatcham Research flags SERMI concerns

Thatcham Research has raised awareness of growing industry concern ahead of the introduction of the Security-Related Repair and Maintenance Information (SERMI) scheme, set to come into force on 1 April 2026.

Having identified a level of nervousness across the sector, Thatcham Research has engaged with stakeholders to better understand the potential impact and explore how it can support insurer and repair partners as the changes take effect.

According to the Independent Garage Association (IGA), the scheme will restrict access to security-related repair and maintenance information for vehicle manufacturers (VMs) that choose to adopt it. While SERMI is mandatory across EU member states under Commission Delegated Regulation (EU) 2021/1244, its application in the UK is voluntary. However, a number of major manufacturers – including Stellantis, Volvo, Jaguar Land Rover, Nissan, Toyota and Ford – have already opted to participate.

Uncertainty remains around the scope of restricted data, as each VM defines what constitutes “security-related” information. While key coding and immobiliser functions are expected to be included, the impact could extend further to areas such as ECU coding and components linked to VIN-based security protections.

From April, existing routes to access this information may no longer be available. As a result, any business requiring access will need to register as a recognised independent operator (IO), regardless of whether they are an approved or independent repairer.

The registration process involves an online application supported by documentation, including basic DBS checks for business owners and technicians. Costs are set at £1,800 for five years or £30 per month over the same period, with additional fees for further technicians. The process can take between six days and one month to complete, excluding DBS processing times.

With timeframes tightening, the IGA and Thatcham Research are urging early action. Repairers are encouraged to engage with VM support teams or the IGA to clarify requirements, while insurers are advised to assess the potential implications across their repair networks.

Thatcham Research has also called for greater transparency from manufacturers adopting the scheme, alongside a coordinated implementation approach to minimise disruption and protect consumers as the industry adapts to the new requirements.
