About OffPeakly

OffPeakly is an independent electricity timing tool for UK households using, considering, or comparing Octopus Agile-style half-hourly pricing.

It helps answer quick timing questions: what the current price is, when the next useful cheap window starts, whether an appliance is worth delaying, and when tomorrow's prices are ready.

Why it exists

Most Agile price pages show the data. OffPeakly makes the data easier to act on.

A half-hourly chart is useful, but it does not always answer the real question. A washing machine needs a run of slots. An EV charge needs a longer block. A negative price is only useful when there is something meaningful to run. A cheap average can still hide an expensive evening peak.

OffPeakly is built around those checks rather than just the raw table.

Who it is for

OffPeakly is most useful for households that can move some electricity use around the day.

That might mean running a dishwasher or washing machine outside peak times, charging an EV when prices are lower, charging a home battery during cheap slots, setting alerts for negative or unusually cheap periods, or comparing Agile against simpler tariffs using realistic usage assumptions.

It is also useful if you are not on Agile yet but want to understand whether your routine fits this kind of tariff.

What it does not do

OffPeakly is not a supplier, broker, switching service, or financial adviser.

It does not switch your tariff, control your appliances, access your smart meter account, guarantee savings, replace a full bill comparison, or know every household constraint.

Use the tools alongside your own tariff details, supplier rules, standing charges, and actual usage.

Independence

OffPeakly is independent. Referral and support links are separate from the calculations shown in the tools.

Calculations are intended to be transparent and conservative. When an estimate depends on assumptions, the page shows or explains those assumptions.

Privacy approach

OffPeakly works without an account.

Alert emails are used only for the alert you create. Smart meter CSV files are processed locally in the browser, and the raw file is not uploaded to OffPeakly.

The main tools do not require access to your energy supplier account.
