Yes, you can, It's your property and locking it is the wise decision. The question should be why you should lock your meter box and what type of lock you should use. Below are the answers to all the questions that can come into anyone's mind when deciding to lock the meter box.
Okay, But Won't That Stop My Meter Reader Getting In?
Not if you use the right lock. This is really the whole trick to the question. Every electricity distributor runs an approved lock system, so their staff can still get in with a master key, even while your box stays locked to everyone else.
In Western Australia, that system is the Western Australian Services (WAS) lock. It gives Western Power, Synergy, the Water Corporation, and Alinta Gas access with one shared lock. Fit that, and your meter reader isn't affected at all.
If you want to install the lock by yourself you can buy DIY Western Power Approved Meter Box Cam lock from our Ebay Store.
What Happens If I Just Use a Padlock I Already Have?
This is where people run into trouble. A regular padlock, even a solid, expensive one, generally isn't part of your distributor's system. Your meter reader won't have a key for it, which means they can't get in.
The usual outcome is that your account gets switched to estimated billing, your usage is guessed based on past readings, rather than an actual read. It's not a penalty exactly, but it's an easy hassle to avoid entirely, just by using the right lock from the start.
Do I Need to Ask Anyone's Permission First?
For a standalone house, no. It's expected, and encouraged, that homeowners lock their own meter box, as long as it's an approved system.
It's a bit different if you're in a strata or shared building. If the meter box is common property, changing the lock without checking first can cause a dispute, even with good intentions. In WA, this generally falls under the Strata Titles Act 1985, which usually makes the strata company responsible for common property upkeep. Worth a quick check with your strata manager if that applies to you.
Is There Any Downside to Locking It?
As long as you are using power-company's approved lock, there's no downside. Using an unapproved lock can block the access of the meter-reader.
What If I'm Renting, Can I Lock It Myself?
Worth checking with your landlord or property manager first, since the meter box is part of the property, not something you own outright as a tenant. Most landlords are fine with an approved lock being fitted, but it's a quick, easy conversation to have before doing it yourself.
Why Should I Even Bother Locking It?
A few genuinely good reasons:
- It stops tampering with your meter, wiring, or main switch
- It reduces the chance of a break-in, since some intruders cut power first to disable alarms or lighting
- It protects curious kids or pets from live components
- It reduces the risk of electricity theft, which is both illegal and dangerous
- It protects against simple accidental damage from garden tools or general wear
None of these are dramatic, day-to-day risks, but they're the kind of thing worth covering off for a relatively small, one-off cost.
What About Emergency Services, Can They Still Get In?
Yes, in many approved lock systems, emergency crews can also gain access if genuinely needed. This is one of the strongest arguments for sticking to an approved lock rather than a private one only you can open, since it keeps the box accessible to everyone who legitimately needs to be there.
So What Type of Lock Should I Actually Buy?
Look for:
- Approval — confirmed compatible with your distributor's system
- Material — brass or stainless steel, both handle outdoor weather far better than basic finishes
- Fit — matched to your meter box's existing hasp, or a hasp kit if it doesn't have one fitted
If you're setting this up for a commercial or strata property, rather than a single home, a restricted key system through an MLAA-accredited locksmith is worth considering instead of a basic padlock.
Quick Recap
- Yes, you can lock your own meter box
- It just has to be an approved lock, so your meter reader and distributor can still get in
- Homeowners generally don't need permission, strata properties may need a quick check first
- Emergency services can usually still access an approved lock system too
- The only real risk is using the wrong lock, not locking it at all
Frequently Asked Questions
Is locking my meter box legally required?
Not typically a strict legal mandate for homeowners, but it's widely recommended for safety and security, and often expected in commercial or strata settings.
Can I get in trouble for locking my meter box the wrong way?
Not trouble exactly, but a non-approved lock can lead to estimated billing until access is restored, which is an easy problem to sidestep.
Do I need a locksmith to fit a lock myself?
Not usually, for a home. If your meter box already has a hasp fitted, swapping in an approved padlock is generally a simple DIY job.
Can I lock a gas or water meter box the same way?
Generally, yes, though it depends on the state and utility. In WA, the WAS lock covers gas and water access alongside electricity, since it's a shared system.
Final Thoughts
Yes, you can lock your meter box, and honestly, you should. The only thing worth getting right is which lock, so it keeps everyone else out while still letting your meter reader, and if it ever comes to it, emergency services, straight in.
