Could your Inner West terrace's old meter board contain asbestos?

Could your Inner West terrace's old meter board contain asbestos? If the board was fitted before the mid 1980s, quite possibly yes, since asbestos cement sheeting was a common material for switchboard and meter panels right across that era. The good news is this doesn't have to derail a switchboard upgrade, it just means the panel gets assessed and handled properly before anyone drills into it, and every new panel fitted afterwards is required to be completely asbestos free.

1. Why Inner West terraces are more likely to have an asbestos board

Large parts of Marrickville, Leichhardt, Petersham, Dulwich Hill, Newtown and Annandale were built or last substantially rewired well before the mid 1980s, when fibre cement sheeting containing asbestos was the standard, inexpensive material for meter and switchboard backing panels. A terrace that's never had its switchboard touched since the original wiring, or one that's only had circuit breakers added over the decades without the panel itself ever being replaced, is exactly the profile where this turns up.

It isn't a sign of a badly maintained property. It's simply what was available and compliant at the time, and the issue only becomes relevant once someone needs to drill into, cut or otherwise disturb that original panel to carry out new work.

2. What the rules actually say about asbestos panels

The Service and Installation Rules of NSW are direct about this. Under SIRNSW Clause 4.4, accredited service providers and electrical contractors should not carry out work that disturbs the integrity of an existing meter or switchboard panel that may contain asbestos, such as drilling into it, without taking suitable precautions first, and guidance on those precautions comes from SafeWork NSW rather than the electrical rules themselves. The same section of the rules also sets the standard going forward: every new service equipment panel installed must not use materials containing asbestos at all.

Put simply, the old panel is handled carefully and the new one is never a risk in the first place. This is the same logic that sits behind our switchboard upgrade guide for Inner West terraces more generally, where an old board is being replaced for capacity reasons as much as for compliance.

3. Signs worth knowing, and why guessing isn't good enough

A flat, grey or off white sheet material behind or around the meter and circuit breakers, especially on a board that predates the mid 1980s and has never had major work done on it, is worth treating as a possibility rather than ruling out by eye. Fibre cement sheeting can look remarkably similar to ordinary compressed cement board once it's painted over or covered in decades of dust, which is exactly why appearance alone is never treated as proof either way.

The only reliable approach is an assessment before any drilling, cutting or forceful removal happens, not after. This matters just as much in a Federation or California bungalow with original wiring as it does in a plainer postwar terrace, since the switchboard material itself isn't tied to any one architectural style.

4. What happens during a safe assessment and removal

Where asbestos is suspected, the first step is identifying it properly rather than working around an assumption. For a small, contained panel this can sometimes be managed with the careful precautions SafeWork NSW sets out for minor work, but where the sheeting is larger, deteriorated or needs to be cut rather than simply unscrewed intact, the job moves to a licensed asbestos removalist before the electrical work resumes. High Demand Electrical coordinates that handover rather than leaving a homeowner to arrange two separate trades independently and hope the timing lines up.

Once the area is confirmed clear, the electrical work, from new circuit protection to a full board replacement, proceeds exactly as it would on any other job, with nothing left behind that still carries the original risk.

5. Why the new panel has to be asbestos free

This part of the rule isn't really a judgement call. Every new service equipment panel fitted anywhere in NSW has to be free of asbestos containing material, full stop, which is one of the easier compliance requirements to meet since modern switchboard enclosures are made from steel or non asbestos composite materials as standard. The practical upshot for an Inner West terrace is that a genuine switchboard upgrade doesn't just add capacity and modern safety switches, it also permanently closes off this particular risk at that location.

6. How this fits into a broader switchboard upgrade

Asbestos handling is rarely the main reason someone books a switchboard upgrade in the first place. It's far more often found along the way, when a home is adding an all electric load, a solar and battery system, or simply running out of spare circuit space on an old board. Building the possibility of an asbestos panel into the quote and the schedule from the outset, rather than treating it as a nasty surprise halfway through the job, is the difference between a one day visit and a stop start job that drags on for weeks.

The same applies where the switchboard's actual position in the home needs to change as part of the upgrade, which brings its own separate set of switchboard location rules to work through alongside the asbestos question.

7. What it means for strata and multi unit buildings

Older Inner West walk up apartment blocks and strata titled terraces often share exactly the same original meter board materials as a standalone house of the same era, just multiplied across several units on one common board. A strata committee planning a main switchboard replacement benefits from getting an asbestos assessment done as part of the scoping stage rather than after a contractor is already on site and ready to start cutting into the existing panel, since a larger shared board can mean a larger area to assess and, occasionally, a larger removal scope than a single home would involve.

Why It's Level 2 ASP Work

Connecting, testing and energising a replacement switchboard still sits with a Level 2 electrician, exactly as it does for any other service equipment work, regardless of whether an asbestos panel was involved beforehand. What changes is the sequencing: the assessment and, where needed, licensed removal has to be genuinely finished and the area confirmed clear before the Level 2 work on the new board begins, never run in parallel or treated as something that can be sorted out after the fact.

How High Demand Electrical Helps

We're a licensed local team working on Inner West terraces every week, not a call centre reading from a script, and we'd rather flag a suspected asbestos panel honestly during the initial site assessment than discover it mid job and have to stop. Where removal is needed, we coordinate directly with a licensed asbestos removalist so the handover between trades is organised properly, and we keep you informed the whole way through rather than leaving you to manage two separate contractors. The same careful, no surprises approach applies across our sister site's work on private power pole connections for Sydney properties, and to electrical safety inspections on this side of the business, where an older board's condition is exactly the kind of thing we'd flag honestly rather than skim over.
