Your energy bill is mainly the energy you use multiplied by your tariff’s unit rates, plus standing charges and any account adjustments. The price-cap headline is a comparison benchmark, not a ceiling on your household’s total spending. The most useful first step is to check billed kWh, the billing dates and the rates actually printed on your statement.

What the £1,723 price-cap headline means
Ofgem’s published October–December 2026 page gives a £1,723 annualised headline for typical Direct Debit use. It also publishes the following average rates. Your regional and payment-method rates can differ. Use your own tariff for a bill calculation; neither the headline nor an annualised example predicts the next 12 months of prices.
| Charge | Published GB Direct Debit average: 1 October–31 December 2026 |
|---|---|
| Electricity unit rate | 26.32p/kWh |
| Electricity standing charge | 54.83p/day |
| Gas unit rate | 7.97p/kWh |
| Gas standing charge | 29.68p/day |
The quoted electricity and gas standing charges together are 84.51p per day, or approximately £308.46 over a hypothetical 365 days at unchanged rates. An electricity-only household would not add the gas charge. These published figures are a dated reference, not a substitute for a postcode-specific quotation.
Five lines to find on your statement
| Bill line | What to check | What can go wrong |
|---|---|---|
| Billing period | Start date, end date and number of days | Comparing a long statement with a shorter one |
| Meter readings | Actual, customer-supplied or estimated readings | A catch-up adjustment can look like a sudden change in use |
| Energy consumed | Electricity and gas kWh separately | Treating a gas meter’s volume units as kWh |
| Tariff rates | Each applicable rate and the change date | Applying one price across a period containing a rate change |
| Account balance | Payments, credits, previous debt and charges | Confusing the Direct Debit with the cost of that month’s energy |
A fixed monthly Direct Debit is a payment towards the account. It can be higher or lower than the energy charged during that particular month. To understand usage, compare the consumption section first. To understand the amount collected, then reconcile the opening balance, new charges, credits and payments.
Ofgem explains the tariff and bill components here. A fixed tariff fixes specified rates for a contract period; it does not fix how many units you consume. On a multi-rate tariff, calculate each rate band separately.
A worked 30-day electricity bill
Suppose a hypothetical statement shows 240 kWh over 30 days at 26.32p/kWh and 54.83p/day. The energy charge is 240 × £0.2632 = £63.17. The standing charge is 30 × £0.5483 = £16.45. Together they are £79.62, before any separate account adjustments. This example uses the published rates above as displayed; do not add tax again to a rate already inclusive of applicable tax.
If a previous statement covered 35 days, its higher total would not by itself prove waste. Convert both periods to kWh per day. Here, 240 ÷ 30 = 8 kWh/day. Compare with a period of similar weather and occupancy, especially if electricity supplies heating or hot water.
For a bill that straddles a tariff change, split the consumption and days using the supplier’s documented allocation. If that allocation is estimated and appears wrong, provide dated meter readings and ask the supplier to explain the correction rather than silently substituting a guess.
Why gas meter units do not match the billed kWh
A gas meter generally records volume, while the bill charges for energy. The government’s gas-bill calculation guide explains the conversion. For a metric meter, volume used is multiplied by the bill’s calorific value and 1.02264, then divided by 3.6. Imperial readings need the appropriate volume conversion first.
Use the calorific value shown on the actual bill. Do not compare a raw gas-meter difference with an electricity kWh reading or reuse a conversion factor without confirming the meter type. Photograph the meter display and its units if you need the supplier to investigate a mismatch.
Three practical fixes, chosen from what the bill shows
1. Fix the reading or tariff mismatch first. Confirm the meter serial number, submit an accurate reading through the supplier’s approved channel, and compare annual costs using the same annual kWh on each tariff. Include standing charges and exit fees. A lower unit price can still be a worse deal for a low-use household if its daily charge is substantially higher.
2. Reduce a measured electricity load. Pick one repeatable activity: a lighting circuit, unnecessary standby load, or a laundry programme suitable for the clothes. For example, replacing a hypothetical 40 W lamp with an equally suitable 6 W lamp used four hours daily avoids 49.64 kWh per year. At 26.32p/kWh that is about £13.07, assuming those hours and rates. An existing efficient LED will not produce that saving.
For standby loads, measure before buying accessories. See the standby-power checklist. Keep refrigeration, alarms, medical equipment and devices that need continuous service powered as required. A blanket “save 10%” promise is not supported by every household’s load profile.
3. Address an actual heat-loss problem. Check unwanted gaps around external doors and windows and suitable draught-proofing options. Keep designed ventilation open. Energy Saving Trust distinguishes unwanted draughts from necessary airflow. Choose materials appropriate to the building, and seek help for older or unusual construction. Do not assume every room needs more sealing.
A seven-day check that produces useful evidence
On day one, record electricity and gas readings, the time and your tariff. Note whether the heating, EV charger or immersion heater is operating. Over the next week, write down unusual events: visitors, extra laundry, a cold spell or charging a car after a long journey. On day seven, read the meters at approximately the same time.
Change one controllable habit at a time and keep comfort and normal needs consistent. A single week cannot establish annual heating savings, but it can reveal an unexpectedly continuous electrical load or an incorrect schedule. Use longer, seasonally comparable data before paying for major equipment.
Questions worth asking before a bigger upgrade
If a large share of the bill is heating, obtain a heat-loss assessment before selecting equipment; the UK heat-pump cost and grant guide explains the quote components. If charging drives the increase, use the UK home-charger guide and compare whole-home tariff costs.
Will solar remove standing charges? Not while the relevant supply remains connected under a tariff that charges them. Solar may reduce imported kWh, but fixed charges require separate treatment.
Should I divide the price-cap headline by 12? That can describe the benchmark monthly equivalent, but it is not your personal budget. Use actual annual consumption, the tariff and your account balance instead.
What if the bill still looks wrong? Send the supplier a concise record of the disputed dates, readings, meter identity and calculation. Keep copies and follow its complaints process if the explanation does not resolve the discrepancy.
