When should you engage a larger contractor for modular or commercial electrical builds?

Opt for a larger contractor when the project involves modular construction, complex fitouts or school and commercial requirements that require coordinated design and approvals. For basic home work, a local domestic electrician is usually more economical and quicker. The trade-off is scale and integration versus price and speed, so consider requesting a combined proposal from both a specialist and a broader contractor to compare. Practical next step: specify the scope and obtain two to three detailed proposals to judge capability and value.
