01Equipment demand
List the equipment you may use together, including heating and machinery. For larger tools, send the manufacturer's electrical requirements. This helps establish the demand rather than assuming every garage only needs power for a few small appliances.
02Attached or detached route
Explain whether the garage is attached or detached, its distance from the house and any wall crossings. Show paving or landscaping along possible routes. Both the route and the existing electrical supply affect the work required.
03Power at usable positions
Mark benches, doors and storage so the sockets remain accessible once the garage is in use. Discuss isolation, lighting and any provision you want for future equipment before the supply route is completed.
