What to Tell Your Neighbours Before Installation Day

You're not legally required to tell your neighbours you're installing solar, but scaffolding, noise, and shared access make a short heads-up genuinely worth giving before the actual work gets underway.

What does a typical installation day actually involve that a neighbour might notice?

Scaffolding, ladders, or lifting equipment visible from an adjoining property, some drilling or mounting noise during the working day, and a delivery or installer vehicle parked nearby, sometimes on a shared driveway or a narrow access road. A standard landed home installation usually runs 1 to 3 days on site, a short but genuinely noticeable window for anyone living right next door to an active work site.

Why give a heads-up if it isn't legally required?

Because the alternative, a neighbour discovering scaffolding and unfamiliar workers with no warning, tends to generate more friction than a short conversation a few days ahead ever would. This is squarely the kind of good-neighbour practice BCA's own guidance for homeowners doing construction work encourages, even where solar specifically carries no formal notification requirement. It's also simply practical: a neighbour who understands what's happening and why is far less likely to escalate a minor inconvenience into a genuine complaint than one caught completely off guard.

What should you actually tell them?

The rough dates, roughly how many days of work to expect, and anything specific that might affect them directly: scaffolding visible from their side, a work vehicle needing a shared driveway, or noise during particular hours. Keeping it brief and genuinely practical, rather than an exhaustive technical explanation of the system itself, is usually all that's actually useful to the person receiving it.

Does a shared driveway or narrow access road need special handling?

Worth flagging directly to whoever else relies on it, even without a formal requirement to do so. A work vehicle parked for a day or two on a shared or narrow access point is a minor inconvenience most neighbours will accept without issue, provided they know in advance rather than encountering it unannounced.

See party walls and boundaries on a terrace house for how this consideration compounds specifically on an intermediate terrace unit bounded by shared structure on both sides.

Does this change if the property is part of a strata cluster development?

The courtesy conversation with immediate neighbours still applies the same way, but a cluster house under an MCST adds a separate, formal layer entirely distinct from this: approval from the MCST itself before installation can even proceed. See solar for strata and cluster homes for that formal process, which runs alongside, not instead of, the informal neighbour conversation covered here.

What don't you actually need to worry about telling a neighbour?

You don't need their permission, their sign-off, or a formal notification through any authority, for a standard installation on your own landed property. The heads-up covered here is entirely a courtesy, not a step that affects whether your installation can legally proceed, which is worth knowing so the conversation doesn't feel like seeking approval you don't actually need.

What if a neighbour actually has concerns once they hear about it?

Listen carefully to the specific concern rather than assuming it's a broader objection to solar generally, since it's often something narrow and genuinely addressable, timing, a particular access point, or noise during specific hours of the day. Most concerns raised this way turn out to be practical scheduling questions rather than genuine opposition to the installation itself, and treating them that way from the outset usually keeps the conversation short and constructive.

Should you also tell neighbours further down the street, not just next door?

Generally not necessary for a standard installation, since the practical disruption, scaffolding, noise, vehicle access, is realistically confined to the immediately adjoining properties. A wider heads-up makes more sense only where a shared access road or driveway genuinely serves several households beyond your immediate neighbours.

Is a verbal heads-up enough, or should it be in writing?

A verbal conversation is generally sufficient for a standard courtesy notice, and most neighbours don't expect anything more formal for routine construction-adjacent work. Following up with a brief written message, a text or a note, is a reasonable option if you want a record of having raised it, particularly on a street where you don't know a neighbour especially well.

Neither approach is a legal requirement, so the right choice comes down to what actually suits the specific relationship and street, not a fixed rule.

What should you actually do in the days before installation?

A short, friendly conversation or a note through the letterbox a few days ahead, covering the dates and what to genuinely expect, is generally sufficient for a standard installation.
