Your energy — a full year, at today’s prices
£2,460/yr
Electricity and gas together, modelled from your meter readings.
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 itAt cap rates this works out near £2,460/yr (your smart meter), so a right-sized direct
debit would be about £215.26/mo — enter what you actually pay and I’ll show whether
you’re over- or under-paying.

These figures are from your own smart meter — tell me your monthly direct debit and I’ll check it against what your energy actually costs.
💰 Your direct debit through the year
How a fixed direct debit moves through the year
A fixed monthly direct debit stays the same all year, but your energy costs more in winter and less in summer. So you naturally build up credit in the cheaper summer months and draw it back down over winter — the balance swings within the year even when the direct debit is right over the whole year.
●Let it ride
Leave the direct debit as it is — if it's the right size for your year (that's what the direct-debit check looks at), the summer credit covers the winter draw-down.
●Adjust your direct debit
Ask your supplier to change the monthly amount if you'd rather smooth the balance differently — for example to build less credit, or more.
This is the normal seasonal cash-flow of a fixed direct debit, not a judgement on whether your direct debit is the right size — that's the direct-debit check. All figures are £ per month. Both options are equally valid; the choice is yours.
📊 Your forecast
Your year ahead — should you fix?
The cap could rise again into winter — when your heating, and any rise, bite most. Here’s what you’re
likely to pay across your gas and electricity as the cap moves. On about 11,466 kWh of gas + 4,963 kWh of electricity a year.
Your year ahead, on your usage
Likely about £2,492/yr
That’s about £32 more a year than you pay now — roughly £3 a month.
Staying on the price cap, across your gas and electricity. Likely between about £2,453 and £2,649 depending on how far the cap rises this winter.

💡 Worth knowing
A few things worth knowing about your bill
🔌~4 kWh / £1Estimate
At your rate of 26.4p a unit, £1 of electricity buys about 4 kWh — roughly 34 kettle boils. A handy feel for what your power actually costs.

⚡Tariff fit: a time-of-use tariff could suit you.About 36% of your electricity is used overnight and your day is fairly peaky — so an Economy 7 / EV / time-of-use tariff (cheaper at night, dearer at peak) may beat a flat rate.

Worked out from your own half-hourly readings against the current cap rate for your region (26.38p a unit, 53.9p a day standing charge). Unlike gas, electricity has time-of-use options — but this is the simple total: how much, and how it stacks up. (The when-you-use-it detail is in ‘Your usage’ below.)
£1,506a year on electricity at today’s rates — about 4,963 kWh
Standing charge — 53.9p a day, the fixed daily fee£197 / yr
The power you use — 26.38p a unit£1,309 / yr
About £197 a year (13% of your electricity) is the standing charge — you pay it before using any power. Using less cuts the power you use, not this fixed fee.
⚡about 84% more electricity than a typical homeA typical home uses about 2,700 kWh of electricity a year (Ofgem).

🌙 Move it around
What if you moved some use to cheaper hours?
A different lever from using less: run flexible things — the dishwasher, washing, the EV — overnight instead of at peak. Same energy, cheaper hours.
£87a year saved on a night-time tariff if you move about 1 kWh a night into the cheap window
Night 9.5p vs day 33.32p a unit, cheap window 00:30-05:30. Based on your own evening use — about a third of your 3.1 kWh evening peak.
On your current flat tariff (26.38p a unit) this saves £0 — you pay the same whenever you use power. This is what a night-time (time-of-use) tariff would save you. See the tariff comparison on this page to weigh up switching.
🔥 Your gas
What your gas is really costing you
Worked out from a full year of own gas readings against the current cap rate for your region (7.26p a unit, 33.3p a day standing charge). Gas is one flat rate — no clever timing tricks — so this is simply: how much, and how that stacks up.

A fixed daily fee of 53.9p on your electricity that every supplier charges before you use a single unit (your gas meter has its own standing charge too). Easy to miss — but a real part of your bill.
→ Standing charges vary between tariffs — it’s built into the deals comparison below.
▲~£597/yr above a typical home on electricity
Your electricity use is about 84% above the Ofgem typical home.
→ 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.
Your average day
Where it goes (estimated)
A best guess from the shape of your usage: your meter records the totals, not which appliance is which, so we split them by time of day and by what’s always drawing in the background. The appliance names are typical examples for each slot, not devices we can actually see.

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.

☀️ Your seasons
Good news — summer is your cheaper season
Your electricity use runs about 13% lower per day in summer (around 13.0 kWh/day) than in winter (around 15.0 kWh/day). That swing is normal — shorter, warmer days mean less lighting and heating-related electricity.
Your summer electricity use is about 13.0 kWh/day versus 15.0 kWh/day in winter — around 13% lower per day in summer. That swing is normal.
Based on your OWN summer vs winter daily use (kWh/day). A higher winter figure isn't a fault or a broken meter — it's the season.
⏱️ Is now a good time?
Run it now, or wait a little?
A gentle steer on when to run something power-hungry — from your region’s live
grid, not a national figure. Two simple signals: how clean the grid is now, and the cheapest upcoming half-hour.
🌱Cleaner after 20:00Your area’s grid is around 146g CO₂/kWh now, dropping to about 79g then — a greener moment to run the dishwasher, washing or an EV charge.
⚡Cheapest upcoming window: tomorrow at 11:30Around 8.5p/kWh then — about 27.6p/kWh less than running now. On your flat rate that won’t change your bill, but on a time-of-use tariff (like Octopus Agile) that gap is exactly the saving you’d unlock.
Live grid carbon for your region (Carbon Intensity API), and real Agile rates via Octopus’ free API. A gentle nudge, never a nag — and we’d never imply a saving your tariff doesn’t give you.

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 sessionYou 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.
