Fixing problems with your smart meter’s in-home display
An in-home display (IHD) is a small portable screen that shows you how much energy you’re using. This is not the same as a smart meter. Your smart meter will be in a fixed position, usually in a cupboard inside or outside your home.
We can help you find the digital user guide for your IHD - even if you don't know what model it is. Find the user guide for your in-home display.
If your supplier gave you the IHD less than a year ago, they should be able to help you with it. They can often repair or replace it. If they won’t help you with it, contact them to make a complaint.
If your supplier won’t fix your IHD and the user guide doesn’t help, there are some things you can try to deal with the problem yourself.
If your IHD stops showing your energy usage or prepayment balance
Wait for an hour and check if this information has come back.
If your usage or balance hasn’t come back after an hour, your IHD might be having trouble connecting to your smart meters.
You can try to fix this by moving your IHD so:
it’s closer to your meters
there are as few walls as possible between your IHD and your meters
you can still look at it easily
If you have smart meters for both gas and electricity, it's usually best to make sure your IHD is closest to your electricity meter.
You might need to plug your IHD into a different socket and wait for it to restart.
After you move your IHD, it should connect to your meters within 24 hours and show your energy usage or balance. To make sure it has connected properly, you can check the meter readings on your in-home display and compare them with the readings on your smart meters. They should be the same or very similar.
If you’re not sure how to read your meters, you can:
If your IHD hasn’t connected to your meters after 24 hours
Contact your supplier and tell them. In many cases they can fix it by turning your communications hub off and on again - you won’t usually be able to do this yourself.
If they can’t help fix it or this hasn’t worked, it might be because your meters have stopped working in smart mode. This might happen if:
you have an older type of smart meter and you switched supplier
your supplier has gone bust
If your meter isn’t working in smart mode, you’ll need to send regular meter readings yourself.
You should still be able to use your online account or app to check your usage or prepayment balance. You can also contact your supplier to ask for this information.
If your IHD won’t turn on or the screen is blank
Check if your in-home display is:
plugged in or has working batteries
switched on - if it has an ‘on’ button
If your IHD still isn’t working, you might be able to use your online account or app to check your meter readings, usage, or prepayment balance. You can also contact your supplier to ask for this information.
If your IHD readings don’t match what your smart meters say
The readings on your IHD usually take a bit longer to update than the ones on your meters - this delay is normal.
If your supplier asks for meter readings, take them from your meters rather than your in-home display. You can:
If your IHD starts working differently after you’ve switched suppliers
This can sometimes happen if your old supplier doesn’t give the right information to your new supplier.
If it’s been over 48 hours since your in-home display started working differently, contact your new supplier to check if there are any problems. If there are, your supplier should help fix them so your IHD starts working again.
Check if your IHD has started working properly again
You can check your IHD has started working properly again by:
comparing the tariff information on your IHD with your bill or new contract - for example, the tariff name, unit rate and standing charge
checking that the meter readings on your IHD are similar to the ones on your meters
If your supplier can’t help you fix any problems, it might be because you have older types of smart meters. This can mean that your meters are no longer working in smart mode. Check your meters are still working in smart mode. If your meters aren’t working in smart mode, you’ll need to send regular meter readings yourself.
You can use your online account to check your meter readings, usage, or prepayment balance. You can also contact your supplier to ask for this information.
