The energy price cap is often presented as one annual bill, but boilers, heat pumps, air conditioning, batteries and EV chargers do not run on that headline. They run on units of gas or electricity, at the tariff and efficiency of a real home.
The short answer
Ofgem says the price cap for a typical dual-fuel household paying by Direct Debit will be £1,723 a year from 1 October to 31 December 2026, up 4% from £1,663. That is not a maximum household bill. Under the national Direct Debit averages, electricity will be 26.32p per kWh with a 54.83p daily standing charge, while gas will be 7.97p per kWh with a 29.68p daily standing charge. Actual rates and bills vary.
What matters most
- The £1,723 figure is an annualised illustration based on typical use—not a limit on the total bill.
- Gas unit prices rise more sharply than electricity in the October national averages.
- Household electricity has no VAT from 1 October 2026 to 31 March 2027; gas retains 5% VAT.
- A heating decision needs the home's demand, tariff and system performance—not the cap headline alone.
What changes on 1 October 2026?
Ofgem announced on 26 August that the energy price cap will rise by 4% for the final three months of 2026. Its typical dual-fuel Direct Debit illustration moves from £1,663 to £1,723 a year if the October rates were sustained for twelve months.
The regulator's national average Direct Debit electricity unit rate changes from 26.11p to 26.32p per kWh, while the electricity standing charge falls from 57.19p to 54.83p a day. The average gas unit rate rises from 7.33p to 7.97p per kWh and the gas standing charge rises from 29.04p to 29.68p a day.
These figures cover England, Scotland and Wales and are rounded averages. Region, payment method, meter and tariff affect the rates on an individual bill. A fixed-tariff customer is not directly moved onto the cap rates simply because Ofgem publishes a new period.
Why the price cap is not a maximum bill
The cap limits the rates an energy supplier can charge customers on protected default tariffs. It does not provide unlimited energy for £1,723. A household that uses more gas or electricity than Ofgem's typical consumption assumptions will pay more; one that uses less will normally pay less.
Standing charges continue even on low-use days. Unit charges then rise with consumption, so the useful starting point for a home-energy review is twelve months of actual kWh—not the monthly Direct Debit amount, account balance or national headline.
Ofgem also changed its Typical Domestic Consumption Values in July 2026 because households are using less energy than under the previous benchmark. That makes direct comparisons with older cap headlines misleading unless the underlying consumption assumptions are checked.
What does the electricity VAT change do?
From 1 October 2026 to 31 March 2027, VAT is removed from household electricity bills. The government says customers do not need to apply: suppliers should apply the change to electricity use and the electricity standing charge. Gas continues to include 5% VAT.
Ofgem's October tables therefore show electricity figures without VAT and gas figures with VAT. This is one reason the new rates cannot be compared mechanically with previous periods or copied into an old spreadsheet without checking the tax basis.
The VAT change reduces the electricity side of the bill relative to what it would otherwise have been, but it does not guarantee that every electric technology becomes cheaper than every gas alternative. Equipment efficiency, controls, usage pattern, tariff and installation design still decide the result.
Does the new cap make a heat pump cheaper than a boiler?
The published unit rates are inputs, not a verdict. A gas boiler buys gas and converts part of it into useful heat. A heat pump buys electricity and moves heat into the home, so one kWh of electricity can provide more than one kWh of heat. The seasonal result depends on the actual boiler efficiency and heat-pump performance.
Flow temperature, heat emitters, weather compensation, hot-water settings, cycling and the building's heat loss can all affect heat-pump performance. Boiler condition, return temperature, controls and system losses affect gas use too. Comparing 26.32p with 7.97p without including performance compares fuel inputs rather than delivered warmth.
A useful comparison models the same home's annual heat and hot-water demand under each suitable design. It should also separate capital cost, grant eligibility, maintenance and tariff assumptions instead of hiding them inside one promised saving.
What about air conditioning, batteries and EV charging?
A reversible air-conditioning system is also a heat pump, but it serves rooms through warm or cool air rather than a wet radiator circuit. Its running cost depends on which rooms operate, for how long, at what temperatures and with what seasonal performance. The cap does not predict those details.
A home battery does not create energy or remove the standing charge. It can shift electricity between times when paired with a suitable tariff, or store solar generation for later use. Its value depends on usable capacity, losses, power limits, cycling pattern, tariff spread and the household's demand.
EV charging adds substantial electricity use, but cost depends on vehicle efficiency, mileage, charging losses and tariff timing. A specialist off-peak tariff may behave very differently from the national single-rate cap average, while its daytime rate may be higher. Compare the complete tariff against the complete home.
What should a homeowner do before winter?
Start with the supplier's actual October rates and check whether the current tariff is fixed or variable. Record annual gas and electricity kWh, then separate heating, hot water, household electricity and any EV demand where the evidence allows. Do not convert a Direct Debit into consumption without the bills.
For an existing heating system, practical steps include using sensible controls, checking schedules, avoiding unnecessary temperatures and arranging appropriate servicing when due. A fault, combustion concern, carbon-monoxide alarm or loss of heating needs the proper safety or repair route—not an energy-saving experiment.
If equipment is approaching replacement, compare designed options around the home and the outcome wanted. The October cap is useful current evidence, but a three-month price period should not be treated as a forecast for the whole life of a boiler, heat pump, solar array or battery.
- TariffUse the actual regional unit rates, standing charges and payment method.
- DemandWork from twelve months of gas and electricity kWh where available.
- PerformanceCompare useful heat or service delivered, not fuel prices in isolation.
- UncertaintyShow which future prices, usage patterns and efficiencies are assumptions.
Use the new rates as evidence—not as the whole decision.
The October 2026 price cap matters because it changes the rates paid by many default-tariff households and alters the relationship between gas and electricity. It still cannot tell a homeowner what their bill will be or which technology suits their property.
Vireo's approach begins with the home, its energy demand and the comfort result required. The next useful step is to decide which upgrade deserves attention first, then build a survey-led comparison with visible assumptions rather than a saving guessed from the national headline.
Before you move forward.
Is £1,723 the most I can be charged?
No. It is an annualised typical-use illustration for a dual-fuel Direct Debit customer under the October cap. Your bill depends on how much energy you use and your actual regional rates, payment method and tariff.
What are the October 2026 average unit rates?
Ofgem lists national Direct Debit averages of 26.32p per kWh for electricity and 7.97p per kWh for gas. Regional rates differ, and standing charges apply separately.
Is electricity VAT-free from October 2026?
Household electricity has no VAT from 1 October 2026 to 31 March 2027. The government says suppliers apply the change automatically. Gas retains 5% VAT.
Can I use the price cap to calculate heat-pump savings?
It can supply current tariff inputs, but not the complete answer. A comparison also needs the home's heat demand, the proposed system's seasonal performance, the existing system's efficiency and the applicable tariff.
