Storage or water heating
Use “Heat water” or “Custom load” for an energy estimate. For Economy 7, check the actual off-peak hours and heater controls with your supplier.

Off-peak on your tariff. Flexible in your day.
The current GB signal supplied by Elecz uses Octopus Agile’s London reference. It is not a universal wholesale price or the rate on every household bill. Use your own tariff to plan charging and other flexible loads.
Loading market data…
The GB signal currently uses Octopus Agile.
Elecz identifies the GB source as Octopus_Agile and defaults to the London reference. Agile is a particular supplier tariff, not a GB-wide wholesale benchmark. This page displays the source label and preserves p/kWh units. Compare with your own region, supplier and tariff; we do not infer its final rates from this reference.

EV charging
Choose “Charge an EV” and compare with the dedicated charging band, if your plan has one.
Compare my electricity use →Laundry / dishes
Choose the appliance and edit the estimate. A shift changes your energy bill only where your tariff rewards it.

This GB page covers Great Britain’s market signal. Northern Ireland is part of the all-island Single Electricity Market with Ireland, so do not use GB as a Northern Ireland retail reference. Ofgem’s regional retail rates and standing charges are also distinct from the market-price signal shown here. Economy 7 hours also need checking with your supplier; the signal does not redefine them.

Before you run an appliance
Does the price cap equal the number on this page?
No. The price cap concerns eligible default tariffs. The current GB source supplied by Elecz is an Octopus Agile reference, not the price cap or a tariff applicable to every household.
Will Economy 7 be cheapest for everyone?
No. The result depends on how much you use in each band and the rates and charges on your offer. Check your own pattern rather than assuming that seven cheaper hours guarantee a cheaper annual bill.
Should I pick GB for Northern Ireland?
No. This page is for Great Britain. The Ireland page explains the shared wholesale market, but neither page calculates your Northern Ireland supplier’s tariff.
Can the tool schedule an exact continuous charging block?
It can compare energy or power and runtime with available data. It does not guarantee a continuous block of exactly your requested duration and does not control the charger.
