Don-Bur Service Ltd has achieved IRTE Workshop Accreditation for the first time, alongside a Platinum rating under the Maintenance Provision Rating Scheme (MPRS) for its Stoke-on-Trent workshop.
Both recognitions followed an independent audit carried out on 2 July 2026 and are valid until 1 July 2029. The MPRS Platinum rating represents the highest level available under the scheme.
Independent assessment of workshop standards
IRTE Workshop Accreditation extends independent recognition beyond the competence of individual technicians to the workshop operation itself. Don-Bur Service has previously supported individual technician competence through irtec accreditation, while the workshop scheme examines the environment, systems and practices within which those technicians operate.
The Society of Operations Engineers (SOE) describes IRTE Workshop Accreditation as an independent commercial audit of workshop facilities, procedures and practice. The assessment examines areas including premises, equipment, technical staff, management, documentation and quality. Workshops are also expected to provide supporting evidence such as equipment calibration certificates, staff training records, health and safety procedures and completed vehicle inspection documentation.
Don-Bur Service already had the necessary workshop policies, procedures and documentation in place ahead of the assessment. Considerable work was undertaken by the Service team to collate and submit the evidence required for the application, before the workshop underwent its formal inspection. Accreditation was subsequently awarded without the need for remedial work.
Platinum MPRS rating
The same assessment also resulted in Don-Bur Service receiving the Platinum MPRS rating. MPRS is an independent recognition scheme for commercial vehicle workshops and maintenance facilities, developed with support from industry bodies, the Driver and Vehicle Standards Agency (DVSA) and the Office of the Traffic Commissioners.
According to the official MPRS scheme, ratings assess the quality and competence of workshop facilities and their workforce. Platinum is its highest level.
“For workshops with the most advanced facilities, the highest levels of staff qualifications, and full compliance with the latest industry standards.”
The significance of MPRS to vehicle operators is also recognised in the official DVSA Guide to Maintaining Roadworthiness, which describes MPRS as an independent recognition system that gauges workshop facilities and workforce quality through audits and supporting evidence. It states that the higher the rating, the greater the confidence operators should have in the competences of the maintenance provider.
The Traffic Commissioners have also supported the introduction of MPRS. Their 2024-25 Annual Report explains that the scheme is intended to enhance standards and professional practices in commercial vehicle maintenance while providing operators with greater reassurance when identifying high-quality maintenance providers.
What the accreditation means for Don-Bur customers
For customers, the two recognitions provide independent reassurance that Don-Bur Service's workshop operation has been assessed against recognised commercial vehicle industry standards rather than relying solely on the company's own assessment of its capabilities.
The Stoke-on-Trent facility supports commercial vehicle operators with scheduled servicing and inspections, MOT preparation, an ATF lane for MOT testing, LOLER testing, roller brake testing, repairs, shotblasting and painting.
The accreditations also complement Don-Bur's wider emphasis on engineering quality, providing external recognition of the standards applied within its after-sales and maintenance operation.
“Achieving IRTE Workshop Accreditation and the Platinum MPRS rating gives our customers independent reassurance that the standards we apply every day have been assessed against recognised industry benchmarks. What is particularly pleasing is that our existing systems, policies and procedures were already in place and we achieved the accreditation without remedial work.”
