How the Smart Meter Savings Estimator Works
The estimator looks at your household habits and billing behaviour — your meter type, how often you submit readings, whether you monitor usage and how often you get estimated bills — to suggest where savings opportunities may exist. Homes with less visibility over their usage generally have more room to improve, so they see a higher potential range.
Can Smart Meters Save Money?
Smart meters don't directly reduce the price you pay for energy. What they can do is help you understand and manage your usage better, by showing where energy is going and making bills more accurate. Any savings come from the changes you choose to make as a result.
Do Smart Meters Reduce Estimated Bills?
Yes — smart meters can automatically send readings to your supplier, which reduces reliance on estimated bills. That means you're more likely to be billed for what you actually use rather than a supplier's best guess.
Why Smart Meter Savings Differ Between Households
Savings vary because of household size, everyday energy habits, your tariff choice, how much you already monitor your usage and how accurate your current billing is. A home that already tracks usage closely has less to gain than one relying on frequent estimated bills.
Smart Meter Benefits Beyond Savings
Beyond any potential savings, smart meters can offer more accurate bills, easier meter readings (no more manual submissions), better awareness of your energy use through an in-home display, and potential access to time-of-use tariffs that reward shifting usage to cheaper periods.
