Readiness for SERMI remains mixed across the UK independent sector, with some garages preparing for accreditation while others are still assessing the impact ahead of a 2026 launch.
The Security-related Repair and Maintenance Information (SERMI) scheme is moving steadily towards operational reality in the UK, following its establishment across Europe as the framework governing access to security-related vehicle data.
For independent garages, it marks a shift in how security-critical work is accessed and controlled.
Functions such as key programming, immobiliser resets, secure ECU replacement and other security-related operations are increasingly protected by formal access controls.
SERMI represents a structural change in how security-related vehicle work is controlled and delivered.
For independent garages, it offers the opportunity to retain high-value work and compete more evenly with franchised dealers, but only if they are ready to meet the technical, digital and security standards that come with access.
In the UK, the Independent Garage Association (IGA) has worked with industry partners to establish a national framework aligned with SERMI principles.
This provides a single route to accreditation for independent garages and technicians, replacing the need to apply for multiple manufacturer-specific approvals.
SERMI accredidation can secure growing customer parc for independent garages
Without accreditation, Laurence Abbott, chief technology officer at Autotech Connect, warned that many independents risk losing access to a growing area of repair and service work as vehicle security systems become more tightly controlled.
With it, accredited garages can continue to support customers with diagnostics, module replacement and security-related programming.
However, levels of preparedness vary widely across the sector.
Some workshops are already reviewing internal processes, documentation and IT systems in anticipation of accreditation. Others are only just becoming aware of the operational, compliance and investment requirements SERMI will introduce.
The framework also brings increased responsibility for garages granted access to security-related data. Modern vehicles are software-driven and connected, and each secure login represents a potential cyber risk if systems are not adequately protected.
Workshops with weak IT controls could be exposed to data breaches, key cloning or wider security incidents. Responsibility for any failure is likely to sit with the garage, with insurance cover potentially limited if reasonable cyber safeguards cannot be demonstrated. For many businesses, the reputational impact of a breach could be as damaging as the financial cost.
As SERMI access becomes more widely available, cyber security is becoming a core operational issue rather than an optional extra. Secure networks, controlled user access, strong authentication and basic cyber awareness among staff are increasingly essential for any workshop undertaking security-related work.
Accreditation alone will not guarantee capability. Security-critical repairs require advanced diagnostics, software competence and technicians confident working within manufacturer platforms. With skills shortages already affecting the aftermarket, some garages may struggle to use newly accessible data efficiently or safely without further investment in training and tooling.
Abbott said: “SERMI is an important step forward for independent garages, but access to data is only part of the picture.
“Garages also need the right cyber safeguards, processes and technician capability in place.
“The businesses that take a joined-up approach now will be in a stronger position as vehicle security systems continue to evolve.”
