Important information about old electricity meters (RTS meters)

Some older electricity meters are due to stop working correctly because the Radio Teleswitch Service (RTS), which controls switching between peak and off‑peak electricity rates, is being permanently phased out across the UK.

This affects certain Economy 7, Economy 10 and other multi‑rate meters that rely on a radio signal to automatically switch tariffs or control heating/hot‑water schedules.

Watmos Community Homes is unable to arrange these changes because they relate directly to each tenant’s or leaseholder’s own electricity supplier account. This means it is the responsibility of the tenant or leaseholder to take any required action.

What’s happening?

The national RTS system is reaching the end of its life and is being switched off.
Once the service in your area is turned off, any meter that depends on RTS will no longer operate properly.

This means:

  • Your meter might stop switching between day and night rates
  • Storage heaters or hot water systems could run at the wrong times
  • Your energy supplier may be unable to bill you accurately

How could this affect your home?

If you have an RTS meter, your energy supplier will need to replace it.
They will contact you directly to arrange a suitable appointment.
The replacement is normally free and may be a smart meter or another modern equivalent.

It is important you arrange this as soon as your supplier contacts you, to avoid losing heating or hot water when the RTS signal in your area is turned off.

Do You Have an Older Multi‑Rate Meter?

You may have one if:

  • Your home uses storage heaters or electric heating
  • Your meter switches automatically between off‑peak and peak times
  • You are on an Economy 7, Economy 10 or similar tariff
  • There is a small separate box next to your meter labelled Radio Teleswitch
  • Your property has no mains gas

If you are unsure, your energy supplier can confirm this for you.

What you need to do next?

This is your responsibility as the account holder.
Watmos Community Homes cannot update or replace electricity meters because this must be done by your energy supplier.

Please:

  1. Check your meter or contact your supplier if you think this applies to you
  2. Book a replacement appointment when your supplier offers one
  3. Do not ignore letters or messages about upgrading your meter

Upgrading your meter ensures your heating, hot water and billing continue to work normally.
