What is an AEDM?

AE Designated Manager (AEDM) — the core idea

The AE Designated Manager (AEDM) is the named individual responsible for the day-to-day management of MOT testing standards across the AE’s sites.

DVSA guidance explains that the AEDM is the primary point of contact between the AE and DVSA, and is responsible for ensuring the AE’s testing operation is run to the required standard.

What an AEDM is expected to manage

In practical terms, AEDM oversight links together:

• tester competence and annual training/assessment compliance
• how testing standards are monitored and supported at site level
• the quality-management evidence you can show to DVSA
• making sure the correct roles have appropriate access to the MOT Testing Service

AEDM vs Site Manager vs AEC

• Site Manager: typically handles day-to-day operation at a specific VTS (tester supervision, equipment maintenance coordination, and first-line QC activity).
• AEC (AE Consultant): an non-mandatory role with read-only access to MTS so a consultant can advise the AEDM/AEs without conducting or submitting tests.

How MOT Lens supports the AEDM workflow

MOT Lens helps AEs and AEDMs keep operational evidence connected: tester records, training progress, assessment results, QC activity, and equipment status (see MOT Lens for Authorised Examiners).

FAQ

Is an AEDM required?

DVSA guidance expects every AE to appoint an AEDM as part of managing testing standards.

What happens if the AEDM changes?

DVSA expects the AE to have the appropriate AEDM in place, so that DVSA can continue to work through the correct point of contact.

Who does the Site Manager report to?

The Site Manager typically supports day-to-day operation at the VTS and works within the AEDM’s oversight responsibilities.

Can an AEC carry out MOT tests?

No. An AEC is a read-only role intended for advice; it is not a testing role.
