About this guide

Describe the premises, the work required and any restrictions on access or operating hours. Distinguish an ongoing maintenance arrangement from a one-off installation or assessment. Confirm that the proposed team handles your building type and that its service area includes the site. Ask for a written scope covering access, equipment, disruption and completion documents. Clarify who coordinates with building management and how additional work will be approved. This guide helps you find providers; it does not assess electrical systems or verify an individual contractor's qualifications.
