How can we help?

Credit billed customers (monthly billing)

Why has my bill been estimated?

Your smart meter reading will normally be marked with an ‘A’, to show that it is an actual reading taken automatically from your energy meter – and is therefore an accurate record of what you have used. If we have been unable to obtain a recent meter read, you may receive an estimated bill. This will be indicated by an ‘E’ marked in the ‘Heat Charges’ section of your bill (see our ‘Understanding your bill breakdown for more information). Where possible we will try to use your previous consumption to generate an appropriate estimate meter read. However, it may be that you have been charged more or less than expected. Once we can get an actual metering reading from your energy meter, we will work out what you actually owe on your next bill, factoring in any payments you may already have made towards your estimated charges.

If your meter cannot be read for a prolonged amount of time, or you wish for your estimated bill to be updated with an actual meter read, you can submit a meter read through our online form. If you provide us with a manual read, this will be shown on your bill denoted with a ‘C’. 

Our estimates are calculated like this:

  • If we have received actual readings for the previous three months, we will use the average consumption for your home to estimate your new bill.
  • If we don’t have the last three actual reads from your property, we will use the last three months’ average consumption from the other homes in your building to make an estimate.
  • If there has been an issue across all the homes in your building within the past three months, we will use average data from across the country this season to make an estimate about your likely usage.

Why isn’t my payment showing on my bill?

If you’ve made a payment and it isn’t showing on your latest bill from us, it might be because the payment didn’t reach us or wasn’t processed before we issued your bill. However, it should appear on your next bill. If you made a payment within 5 days of your bill being issued it will not show on your bill. It will, however, show on your next bill. If you have any concerns, please get in touch.

How do I submit a manual meter reading if required?

If we are unable to obtain an actual reading from your meter remotely through an Automatic Meter Reading (AMR) system, and you have received an estimate bill as a result, we may ask you to provide us with a manual meter reading. To do this you can submit your reading along with a photograph of your heat meter showing the latest read via our ‘Submit a meter read’ form.

Your heat meter is typically found either inside or near your Heat Interface Unit (HIU), which is normally located within the utility cupboard. Some examples of what your heat meter may look like can be found below. Please contact your building owner or landlord if you’re unable to find your meter. Sometimes your energy meter may be located in a communal area, outside your property. If you need any help locating your energy meter, please contact your internal maintenance team. Please note, Insite Energy is not responsible for the installation or operation of your heat meter.


If you have a combined heating & hot water and cooling meter, you will be able to see your usage for both on the same meter.

Your meter may also display your energy consumption in megawatt-hour (MWh). If this is the case, please times your meter read by 1000 to convert it into kilowatt-hour (kWh) when submit your manual meter reading. This is because the bills we issue are based on kWh. For example, if your meter reads 0.123MWh, you would submit 123 under the 3 digits part of the form because 0.123MWh x 1000 = 123kWh.

Why have I not received my bill?

If you haven’t received a bill in a while, there are a few possible reasons for this. Below, we’ve outlined the most common scenarios:

Your bill may have been sent, but not received. The most common reason for not receiving a bill is that it has been sent but hasn’t reached you. This can happen if a physical bill is lost or delayed in the post, or if an e-bill has been sent to your email but ended up in your spam or junk folder. To resolve this, please check your post, and email inboxes, including your junk or spam folders. If you still can’t find your bill, please contact us to confirm whether one has been issued. 

Your account may be on hold during a tariff review. There may be instances when your heat supplier temporarily instructs us not to issue bills while they review the tariff for your development. Once the tariff review is complete, you will receive a bill covering the period since your last bill and reflecting the change in tariff. There is no action for you to take until you receive this bill. When you receive this bill covering a longer period than usual, we recommend setting up a Direct Debit or payment plan to help manage your payments. To set up a variable or payment plan Direct Debit, please head to ‘my insite’. You can find instructions on how to set up a Direct Debit in our how-to guide

Your account may be on hold due to a billing investigation. Finally, there may also be instances where we will delay issuing you a bill if your meter reads look unusually high or abnormal. In these cases, billing may be paused while we investigate and look to rectify the issue. There’s nothing you need to do during this period as once the investigation is complete, we will issue a corrected bill.
