Dark backing board or old fuses? Leave them alone
Black or dark brown backing boards made before 1987 can contain asbestos, and some old fuse types, Federal fuses among them, can hold friable asbestos inside the fuse carrier. In NSW, any amount of friable asbestos must go to a Class A licensed removalist, and tradespeople aren't permitted to remove it. Don't drill, sand or prise at the board. Mention it when you book so the electrician plans for it.
Why Sydney boards age the way they do
Post-war council and Commission homes
Ryde's council built 599 houses between 1945 and 1952. Sutherland Shire only turned suburban in the early 1950s, and the Housing Commission's Green Valley estate went up between 1961 and 1965. All of it predates 1987, so a dark backing board is worth asking about.
The spread west in the 1960s and 1970s
Blacktown and the suburbs north of Mount Druitt saw large-scale housing in those two decades, and Menai's urban release began in the 1970s. If your board has had circuits added over the years, the electrician will want to see what each one feeds before planning the new layout.
Older still: terraces and Federation homes
Paddington's terraces date mainly from 1870 to 1895, and Haberfield's Federation houses from about 1900 to the 1940s. Whatever has been changed since, NSW Fair Trading recommends any home built before 2000 has a licensed electrician check whether safety switches are fitted.
Knockdowns and new estates
Where a mid-century house has been replaced, as across much of Seven Hills, or a new street has gone in at Box Hill or Oran Park, the board is recent. The question there is spare room for a charger, a battery or another air conditioner later.
Meters on the Ausgrid and Endeavour networks
The switchboard is yours, but on both of Sydney's networks your electricity retailer arranges the meter. On Ausgrid's network, every new or replacement meter installed since 1 December 2017 has had to be a smart meter, and Endeavour Energy says NSW homes are set to move to smart meters by 2030.
So if the upgrade touches the meter, ask early who's contacting the retailer, because that part runs on the retailer's timetable. Ausgrid says a faulty meter should be reported to your retailer, which should arrange a replacement within 15 business days.
If the main switch, the service fuse or the line from the street needs work, that's a job for a Level 2 Accredited Service Provider authorised by your network. Level 2 electricians in Sydney explains that side.
Solar, batteries and chargers on a Sydney board
If solar is on the way, timing matters. From 23 November 2026, new and upgraded systems on Ausgrid's network fall under the NSW Emergency Backstop rules, and Ausgrid wants new inverters that can talk to the network over the internet. Endeavour Energy's rollout runs by postcode from 2 November 2026 to February 2027. The installer looks after the inverter, but the board needs the space and circuits for it.
An EV charger needs its own circuit, and Endeavour Energy expects the electrician to tell it if the switchboard or meter box needs upgrading for one. If both solar and a charger are on your list, have one electrician size the board for both at once.
A switchboard upgrade and a Level 2 EV charger are both on the approved list for NSW Home Energy Saver loans, which are interest-free up to $15,000. Read the scheme's eligibility rules before you book.
Landlords and tenants
In a NSW rental, a faulty safety switch is an urgent repair, and so is any other electrical fault. The condition report at the start of a tenancy records whether there's a safety switch and whether it works, so a board with none is on paper from day one.
Questions for a Sydney electrician before you say yes
- Is my home on Ausgrid or Endeavour Energy, and does this job need anything from the network?
- Could the backing board contain asbestos, and how will you handle it?
- Does the meter need to change, and who's contacting my retailer?
- How much spare room will be left for solar, a battery or a charger?
- Will you lodge the CCEW with my email address so I get a copy?
- What's your NSW licence number, so I can check it on Service NSW?
If it were our board
If the board predates 1987, we'd treat the backing as possible asbestos until someone qualified says otherwise, and plan the upgrade around that. We'd list everything coming in the next few years, from solar to a charger to another air conditioner, and get the board sized for all of it in one visit. Then we'd press the test buttons every six months, as NSW Fair Trading suggests.
