RTS Meters Are Being Decommissioned: What Homeowners Should Know

RTS meters, which control off-peak tariffs using a radio signal, will stop working soon as the signal is permanently shut down. Energy suppliers are replacing them with smart meters, but the upgrade may fail if your existing RTS meter box is too small or damaged.

 

Why Choose a Large 3‑Phase Meter Box for RTS Meter Replacement?

Smart meters come in different sizes and need extra space for a communications hub and proper cable routing. Our large 3-phase meter boxes—available in recessed (794 × 565 × 180 mm) and surface-mounted (794 × 565 × 190 mm) options—offer a roomy internal cavity of approx. 690 × 465 mm, making them ideal for smart meters and future upgrades — especially when replacing an outdated RTS meter setup.
