Solar panel installations and electric vehicle chargers have both seen strong growth across Sydney, driven by falling hardware costs, government incentives, and rising electricity prices. What the sales process for both products often fails to communicate is that a significant proportion of Sydney homes need electrical work done first — performed by a class of licensed tradesperson that most homeowners have never heard of.
What Is a Level 2 ASP?
A Level 2 Authorised Service Provider (Level 2 ASP) is a licensed electrician who holds additional authorisation from the local network distributor — Ausgrid across most of eastern Sydney, and Endeavour Energy across the west and south — to work on the network side of the electricity supply. Standard electricians are not permitted to work on this part of the system. When a property's switchboard is outdated or undersized, a solar inverter or EV charger cannot be legally connected until it is upgraded, and that upgrade must be done by a Level 2 ASP.

The Hidden Cost That Arrives Late
A consumer mains upgrade or switchboard replacement in Sydney typically costs between $800 and $2,500 depending on the scope and the age of the existing switchboard. Much of Sydney's housing stock was built in the 1960s, 1970s, and 1980s with switchboards not designed for modern electrical loads. Adding a solar inverter or a 7.4kW EV charger to a switchboard already working near its designed capacity requires assessment and, in many cases, upgrade.
How to Avoid the Surprise
Level 2 electricians in Sydney who work alongside solar and EV charger contractors have developed efficient workflows for combined projects, meaning the switchboard upgrade and hardware installation can often be coordinated to happen on the same day. For homeowners planning solar or EV projects, building a preliminary conversation with a Level 2 ASP early in the process is the most reliable way to avoid late surprises. The assessment is typically free or low-cost.
The Property Purchase Context
Buyers who commission building inspections occasionally receive reports noting that the consumer mains or service connection requires attention. According to Energy NSW, acting on those findings requires a Level 2 ASP and a formal application to Ausgrid or Endeavour Energy before the work can proceed. Understanding this before exchanging contracts avoids settlement delays.
