THOUSANDS of households have been issued an energy meter warning which they must follow to avoid losing water and electricity supply.
Homes with electricity meters using the Radio Teleswitch Service (RTS), will need to upgrade to a smart meter come June 30.

The RTS switches electricity meters between peak and off-peak rates at certain times of day, letting customers access cheaper off-peak electricity.
But the service is being switched off at the end of June, meaning customers with this type of meter need to get an upgrade.
Around 530,000 households are still yet to upgrade from an RTS meter, according to the latest figures from Energy UK.
A number of councils have flagged the issue to their residents to ensure they do not miss out ahead of the deadline.
That includes Glasgow council who said it would deploy door knockers to directly reach customers and “emphasise the importance of getting an upgrade”.
Councillor Ruairi Kelly, convener for housing and development at Glasgow City Council, said: “It’s really important that anyone with one of these meters has it replaced, as it could lead to them not being able to use their heating.”
Leicester council also warned that around 4,000 need to upgrade their meter.
It said customers should contact their energy suppliers to arrange a meter upgrade.
If you think you have a RTS meter but are not sure what your next steps are it may be worth getting in touch with your local council and supplier.
One way to tell if you have a RTS meter is if your home has a separate switch box near your meter with a Radio Teleswitch label.

RTS meters are also typically used in areas with no gas supply, such as for high rise flats or houses in a particularly rural setting, so if this applies to you it’s worth checking your meter.
If you’re still not sure, contact your energy supplier and ask whether you have RTS equipment. They will be able to confirm for you.
You will not be charged for upgrading an RTS meter to a smart meter as all electricity suppliers are required to offer this upgrade at no extra cost to customers.

Smart meters offer the same features as RTS in that they can record the different prices at different times of day offered by Economy 7 tariffs.
It can help you save money as they help you avoid estimated energy bills as the reading are sent to your supplier automatically.
The device can also help you track your energy use as you can see how much your using and when you using it.
Smart meters are being rolled out by suppliers across the country and around 36million households have one, though they are not without issues.
Around one in ten are thought to be “dumb” according to recent data from Ofgem.
Issues include a broken display and trouble connecting to the network in some areas, while many first-generation smart meters have outdated technology, though this is unlikely to be an issue with ones fitted now.
Suppliers should make efforts to fix smart meters that are not working, but you may have to make meter readings in the meantime to ensure accurate bills.
