Accurate billing, immediately

The clearest benefit is the end of estimated bills. Automatic reads mean your invoices reflect actual usage and your renewal quotes are based on a real consumption profile rather than an assumed one — usually the difference between an accurate price and a cautious one.

Half-hourly data changes how you manage cost

Half-hourly data shows exactly when you use energy. That opens up shifting load away from peak periods, spotting equipment left running overnight, and validating whether an efficiency project delivered what it promised.

What to check before installation

Confirm there is no charge, agree an installation window that avoids trading hours, and check that your existing supplier's meter will still communicate if you switch. Most modern installs are supplier-agnostic, but older units are not.
