What £1,723 actually represents
Ofgem's 1 October to 31 December 2026 price cap is £1,723 a year for a typical household in England, Scotland or Wales that uses both gas and electricity and pays by Direct Debit. It is an annualised illustration, not a promise that your yearly bill cannot go above that figure and certainly not a charge of £1,723 for the final quarter alone. The regulator limits covered default-tariff unit rates and standing charges; bills still reflect usage. Someone heating a large, poorly insulated house could pay more, while a highly efficient flat could pay less. Start with your own meter readings instead of the headline figure.
The Ofgem unit rates in this quarter
For covered Direct Debit customers, Ofgem publishes average electricity costs of 26.32p per kWh plus a 54.83p daily standing charge. The average gas unit rate is 7.97p per kWh with a 29.68p daily standing charge. The actual rates differ by region, payment method and some meter arrangements. They should not be quoted as if every postcode has identical prices. Look at the rate card from your supplier, including whether taxes are already reflected in the displayed figure. Different unit rates apply to some Economy 7 households, while prepayment and standard credit use separate published tables. The official regional breakdown is more useful than a single national average.
A realistic 92-day bill example
Imagine using 650 kWh of electricity and 2,400 kWh of gas over 92 days. With Ofgem's average Direct Debit rates, electricity consumption costs £171.08 and its standing charge about £50.44. Gas consumption costs £191.28 and its standing charge about £27.31. Added together, that gives approximately £440.11 for this illustrative period before account credit, adjustments or a different local tariff. It is not a quotation, and it does not establish what an individual household will pay. Use the same formula with your actual readings and each rate shown on your own bill. If the billing period overlaps rate changes, split the calculation by date.
How to calculate the bill yourself
Take the opening meter reading away from the closing reading to find electricity kWh used. For gas, follow the supplier's conversion from meter units to kWh rather than treating raw cubic-metre readings as kilowatt-hours. Multiply each energy total by the applicable unit price in pounds and add each daily standing charge times the days in the period. Then check discounts, any separate charges and account credit. If a bill uses estimated rather than actual readings, it may not reflect real usage; provide a meter reading where possible. Keep the calculation on a simple spreadsheet or piece of paper so you can compare offers transparently.
Who is covered, and who is not?
The price cap governs relevant household default tariffs, including payment arrangements with their own rates. A fixed-price contract is not automatically reset whenever Ofgem changes the cap, so compare the actual contract terms. Northern Ireland follows a different energy market and should not be folded into the Great Britain benchmark. Business tariffs are another separate case. Customers with smart meters or time-of-use products may have different day and night rates, meaning an average unit price tells only part of the story. When considering a fix, calculate the expected annual cost from your actual consumption, not merely whether its marketing message mentions a cap.
Why an electricity tax change does not settle the bill
Ofgem says the typical cap rose four per cent from the preceding quarter even as electricity VAT treatment changed from 1 October 2026. Energy supply costs, standing charges and usage patterns affect the final number, so an electricity tax cut does not guarantee that every household's total bill will fall. Conversely, a higher national benchmark does not mean each individual household uses or pays more. If you are struggling to pay, contact your supplier early to discuss a realistic repayment plan and possible support. A smart meter can help reveal consumption patterns, but insulation, heating habits and tariff suitability still deserve examination.
The next decision point in November
Ofgem's published schedule says the cap for 1 January to 31 March 2027 is due to be announced by 25 November 2026. That announcement date is not the date the new rates start. Until the new decision is published, forecasts should not be treated as confirmed charges. Keep your latest bill, tariff description and up-to-date readings ready, then review any fixed-rate offers against your own expected usage. The right search question is not simply 'is the price cap £1,723?' but 'what are my electricity and gas unit charges, standing charges and likely kWh use?' The answer can be estimated now, without guessing about winter policy.
