3 Steps to Full Bars
Capture the Signal
Position the outdoor antenna where reception is strongest.
Boost It Indoors
Connect the booster and indoor antenna.
Stay Connected
Help your meter send readings automatically.
Help readings reach your supplier
When weak cellular reception stops automatic reporting, a booster can help restore the connection. Bring stronger signal to your meter’s location so its communications hub can send readings to your supplier.
Better signal where the meter is fixed
Your meter stays where it is. The outdoor aerial captures available signal, while the booster and indoor aerial bring it into the cupboard, cellar or garage where reception is weak.
Make the most of connected readings
Automatic readings mean less manual reporting and help your supplier bill from actual usage. Reliable reporting can also support access to smart tariffs that require half-hourly readings, subject to your supplier’s terms.
Award-Winning Signal Booster (2025 Winner)
Your Questions, Answered.

The kit brings available outdoor cellular signal into the area where your meter is installed. If weak reception is preventing its communications hub from sending readings, stronger signal can help restore automatic reporting.
Our team helps with your meter setup, aerial placement and installation questions after purchase. Contact us through the existing chat, email or phone options for personal guidance.
Core 600 Pro boosts cellular Band 20 (800 MHz) and Band 3 (1800 MHz). It needs usable outdoor signal and a hub using a supported network and band. Long-range radio, the local meter/display network and supplier account faults are outside what a cellular booster fixes.
Yes—the outdoor aerial captures available signal and the indoor aerial brings coverage to the meter’s location. Follow the supplied guide for aerial separation and cable routes. There is no direct connection to the meter, and sealed meter equipment stays untouched.
Restoring automatic readings can help your supplier bill from actual readings. Some smart tariffs also require reliable half-hourly readings. Your supplier confirms that reporting has resumed and that its tariff requirements are met.
