3.7 Changes to Businesses 1 DVSA must be told within 7 working days about any significant changes to the control or operation of the business. Failure to notify such changes within this period maybe treated as a shortcoming under Section I. For further information on changes to business please refer to Section BA company that continues to operate under the same registration and company number may continue testing provided that any changes to the officers of the company or change in the relationship to any parent company have been notified to DVSA in writing. 3 It is possible for the AEDM, or other appropriate roles, to update some authorisation details directly, (e.g. telephone and fax numbers, email and correspondence addresses) via the MOT Testing Service. Any other details must be notified to DVSA in writing. 4 The AE can cease the nomination of a Tester. In the case of a multi-site AE, this cessation maybe from all sites, a selection of sites, or a single site. A cessation by one AE or DC does not affect any current or future nominations by other AEs. DVSA must be notified by recording the change of details on the MOT Testing Service.
