2 Your usage

What your home actually uses

Half-hourly readings turn a vague bill into a clear picture: when you use power, what’s always-on, and how you compare to a typical home.

Live from your smart meter. Figures below are your own half-hourly readings.
£3.93a day on electricity · about 13.6 kWh

What’s costing you

🔌~£452 a year always-onestimated

About 37% of your electricity is a constant background draw — fridge, router, standby — estimated from your quietest half-hours.

Hunt down standby: TVs and set-top boxes, old chargers, a forgotten second fridge.

Sun 02 Nov: about £6 in one day

That day used 23.4 kWh — roughly 1.7× your typical 13.6 kWh. 4 day(s) stood out like this.

Cast your mind back — heating flat out, guests, tumble dryer, immersion heater?

£~£197 a year in standing charges

A fixed daily fee of 54.0p every supplier charges before you use a single unit. It’s easy to miss — but it’s a real part of your bill.

Standing charges vary between tariffs — it’s built into the deals comparison below.

~£564/yr above a typical home

You're about 84% above the Ofgem typical home on current usage.

The evening peak and heating are the usual places to claw this back.

£About 1.3 kWh in your priciest evening hoursestimated

Around 19:00 something power-hungry runs — typically an oven, tumble dryer, dishwasher or immersion heater. We’re inferring from your usage shape (not certain). That’s use sitting in the dearest part of the day on a flat tariff.

Moving it earlier/later, or onto a time-of-use tariff (priced for you below), could cut it.

~£1,435/yr (4,963 kWh) — about 84% above a typical home Based on 365 days of your readings, vs the Ofgem typical-home figure of 2,700 kWh/yr.

Near-term heating outlook. The next 7 days look mild locally (no cold snap forecast), so heating demand should stay low. Indicative only.

Could a time-of-use tariff help?

  • An overnight charging pattern suggests an EV — a day-night / EV tariff prices those overnight units far lower. See what it would cost you below.

What’s coming — your year, forecast

Based on how your home responds to cold weather, on a typical local year. I learn the pattern from your own readings and check it against itself — lately it’s landed within about 9%. It’s a careful estimate with a range, never a promise.

3 Is your bill right?

Are you paying the right amount?

The simplest money rule there is: your direct debit should track what your energy actually costs — no more, no less. Pay too much and you’re handing over an interest-free loan; too little and a winter shortfall is waiting.

Tell me your direct debit and I’ll check it — I won’t guess it At cap rates this works out near £1,435/yr (your smart meter), so a right-sized direct debit would be about £125.54/mo — enter what you actually pay and I’ll show whether you’re over- or under-paying.

A right-sized direct debit for that cost (incl. a small 5% seasonal cushion)

These figures are from your own smart meter — tell me your monthly direct debit and I’ll check it against what your electricity actually costs.

📅 Coming up

The price cap is changing on 1 July

Ofgem has announced the energy price cap will rise about 13% for 1 Jul - 30 Sep 2026. Here’s what that looks like for your home, on your current usage.

About £187 a year more Your energy would go from about £1,435 to £1,621 a year (roughly £16 a more a month). A good moment to check you’re on the best deal — see below.

This applies Ofgem’s announced average rise to your own usage; your exact change depends on your region’s new unit rates, which Ofgem publishes per region. Source: Ofgem price-cap announcement.

5 Your money-saving actions

What to do, biggest win first

Ranked by effort then size — the free, do-it-today wins come first. Every figure is an estimate from your own usage; we keep them realistic and label an ‘up to’ saving as exactly that.

Cut always-on / standby loadup to ~£68/yr
Always-on is ~37% of use (~£452/yr). Cutting standby and replacing an old fridge/freezer could claw back up to ~£68/yr.

Total estimated saving if you do all of the above
~£68/yr

Savings don’t simply add up — some overlap (a cheaper tariff and shifting peak use touch the same units). Treat the total as a realistic indication of the prize, not a guarantee.

Get paid to save

Saving Sessions: get paid to use less at peak

On cold winter evenings the grid pays people to cut their electricity for an hour or two (the Demand Flexibility Service — Octopus call theirs “Saving Sessions”). It’s real money for shifting a wash or a dinner by an hour.

💰 You could earn roughly £1.30–£3.89 per session You typically use about 1.9 kWh in the evening peak, of which ~1.3 kWh looks shiftable. Sessions have historically paid around £1–3 per kWh saved — an illustration from your own usage, not a guarantee (payouts vary by event and supplier).

Sessions run mainly Nov–Mar, announced about a day ahead, and you sign up through your supplier. Coming soon: I’ll alert you when one’s scheduled so you never miss the payout.
