What affects your energy bill?
Your bill is driven by how much gas and electricity you use (in kWh), the unit rate you pay per kWh, and the daily standing charge. Property type, insulation, heating system, and number of occupants all affect usage. Ofgem's current typical use for a medium home is 2,500 kWh of electricity and 9,500 kWh of gas a year. The price cap limits the unit rate and standing charge on a default tariff. A household that uses more than that typical amount pays more.
The cap from 1 October 2026
From 1 October to 31 December 2026, Ofgem's typical dual-fuel bill for a household paying by Direct Debit is £1,723 a year. That is £60 higher than the £1,663 cap for July to September 2026. The same typical use costs £1,861 on standard credit and £1,678 on a prepayment meter. Households on a fixed tariff are not on this cap.
The England, Scotland and Wales average Direct Debit rates for that period are 26.32p per kWh of electricity with a 54.83p daily standing charge, and 7.97p per kWh of gas with a 29.68p daily standing charge. Your standing charge depends on your region, so a Swindon bill will not match those averages exactly. Electricity has no VAT from 1 October 2026 to 31 March 2027. Gas prices include VAT at 5%. The rates are on Ofgem's unit rates page.
How to reduce your bills
Use less energy where you can (thermostat, insulation, efficient appliances), fix leaks and dripping taps, and compare tariffs. If you're on a standard variable tariff, switching to a competitive fixed deal when available can save money. See energy suppliers in Swindon and cheapest energy deals in Swindon for how to compare and switch.
Help with bills
If you're struggling to pay, contact your supplier first. They can agree a payment plan. You may also be eligible for support such as the Warm Home Discount or grants from the council or charities. Citizens Advice and GOV.UK have the latest on help available.
