Looking for a quick breakdown of your power usage? Easy! Just log into My Slingshot to see a handy graph that tracks how much power you are using on a daily basis.

The graph displays differently depending on whether you have a Legacy or Smart meter at your property because they operate and are billed for in distinct ways.

A Legacy meter requires someone to physically read your usage, whereas a Smart meter communicates this information remotely.

Legacy Meters

These older meters require a monthly visit from a meter reader to manually give us your usage.

Your power bill is estimated based on your previous usage; this is to make sure the bills you receive are consistent as we charge in advance. When the actual reading comes through, your next bill is credited or debited depending on whether we over or undercharged you.

The power graph is then updated so you can check your usage. The example graph below shows an actual read being done and that we had underestimated the usage by 98 kW/h for this customer.

^ If you can see 'Change Meter Access Information' within My Slingshot, it means you have a Legacy power meter.

Updating a legacy meter reading

Legacy meter power usage is estimated between readings (which happen every month or longer if a reading visit is not possible). You can submit a manual reading by selecting 'Update Meter Reading' and you will be taken to a page to confirm the meter number and enter in the current reading you see on the meter. This ensures you are being billed accurately.

Smart Meters

These are your typical meters that remotely send daily power readings - we can bill for your actual usage this way. With a 48-hour delay, the power graph accurately shows how much you’ve been using.

^ Blue usage bars are actual reads whereas orange are estimates. You'll see mostly blue for smart meters and mostly orange for legacy.

Frequently Asked Questions

• Why do the readings on My Slingshot look wrong?
  You’ll want to double-check your internal wiring is not the source of the problem, including the hot-water cylinder. If everything seems right, the incorrect readings could be caused by a faulty meter. Give us a call on 0800 89 2000 and we can arrange for this to be investigated – please be aware that there could be a call-out fee if nothing is wrong.
• Can I choose when the meter reader visits?
  The meter reads are co-ordinated by the metering company and cannot be changed.
• My meter is past a locked gate/door, how is this accessed?
  The meter reader will knock on your door to see if someone can unlock this for them. If they can’t get in, they will leave a card with our 0800-number asking you to give us a call and organise a day for access.
• How do I request to move the location of my meter?
  All the details on how to organise a meter move are here.
