Ofgem’s October 2026 Energy Price Cap Rise: What Homeowners Need to Know

What has changed?

The energy price cap limits the rates suppliers can charge customers on protected default tariffs. Ofgem reviews it every three months, taking account of wholesale energy prices, network charges, policy costs, supplier operating costs and other allowances.

For October to December 2026, higher wholesale gas costs are an important reason for the increase. The government’s removal of VAT from electricity bills has softened some of that pressure, but it has not been enough to prevent the overall typical dual-fuel figure from rising.

The £1,723 figure is not a maximum household bill. It is an illustration based on Ofgem’s assumed typical annual gas and electricity consumption. The cap controls unit rates and standing charges, not the total amount a household can be billed. Use more energy and you will pay more; use less and you will pay less.

This distinction matters particularly for larger detached homes, poorly insulated properties and households where somebody is at home throughout the day. Their consumption can sit well above the typical assumptions used in the headline figure.

Why an October increase matters more than the headline suggests

Energy consumption is heavily seasonal. A household does not normally use one-twelfth of its annual gas in each month. Gas demand is relatively low during summer, when a combi boiler may only be providing hot water, but it rises quickly once space heating is switched on.

As a result, the average £5-a-month increase should not be treated as a prediction of what will appear on every monthly statement. A home that uses most of its annual gas between October and March will expose a larger proportion of its consumption to the new capped rates.

Weather also makes a significant difference. A prolonged cold spell increases the amount of heat escaping through walls, roofs, windows and floors. The boiler must replace that heat to maintain the chosen indoor temperature. Turning the thermostat higher increases the difference between indoor and outdoor temperatures, accelerating heat loss further.

Local housing adds another layer. The area around Alton, Farnham and Haslemere includes substantial older housing stock, while Bordon and Whitehill have a mixture of established homes and modern development. Older solid-wall houses can behave very differently from newer properties built to tighter insulation standards. Rural and exposed homes around Liphook may also experience greater wind-driven heat loss than sheltered urban properties.

What the change means technically for gas heating

A modern condensing boiler saves energy by recovering heat from water vapour in its flue gases. To do that effectively, the water returning from the radiators must be cool enough to encourage condensation inside the boiler’s heat exchanger.

Many systems are set to unnecessarily high flow temperatures. The boiler heats the water rapidly, radiators become very hot, and the returning water may remain too warm for sustained condensing operation. The property still heats up, but the appliance may not achieve the efficiency homeowners expect from its label.

Where the system and property allow, reducing the central-heating flow temperature can improve condensing performance. This setting is different from the room thermostat. Flow temperature controls the temperature of water sent to the radiators; the room thermostat controls the target air temperature inside the home.

Adjustments should be made gradually because every system is different. Smaller radiators, poor insulation and very cold weather may require a higher flow temperature. Homes with hot-water cylinders also need suitable stored-water temperatures and controls for hygiene, so boiler settings should not be reduced without understanding how the system is configured.

System balance matters too. If radiators close to the boiler take too much flow, rooms farther away may warm slowly. Occupants often respond by raising the thermostat or extending heating times, even though the underlying issue is uneven water distribution. Correct balancing helps radiators receive an appropriate share of the available flow.

Air in radiators, sludge, sticking thermostatic radiator valves and inaccurate controls can all increase running costs or reduce comfort. A cold strip at the top of a radiator commonly suggests trapped air. A radiator that is cold across the bottom may indicate restricted circulation or internal deposits, although proper diagnosis is important before recommending chemical cleaning or a powerflush.

How much could the price rise cost your household?

The difference between £1,663 and £1,723 is £60 on Ofgem’s typical annualised illustration. Your own change cannot be calculated reliably from that figure alone.

The most useful approach is to check your supplier’s new gas and electricity unit rates and standing charges, then compare them with your previous rates. Recent meter readings or annual statements will show how many kilowatt-hours you actually use.

For example, a household using more gas than Ofgem’s typical assumption could see a larger cash increase, even if its percentage rise is similar. A well-insulated home with efficient controls and modest thermostat settings may spend considerably less than the headline figure. Standing charges also mean that very low users do not see their bills fall in direct proportion to consumption.

Direct Debit amounts can create confusion. Suppliers often spread estimated annual costs across the year and may change monthly payments to account for expected winter use, an existing debit balance or previous underpayments. A sharp increase in a requested Direct Debit is therefore not necessarily caused solely by the 4% cap rise.

Submit an up-to-date meter reading, check whether the bill is based on estimated consumption and review the account balance before comparing tariffs. Customers with smart meters should still check statements for unexpected estimated readings or communication problems.

Fixed tariff or price-capped tariff?

Customers already on a fixed tariff are largely protected from this October change until the fixed term expires, although the contract’s standing charges and any exit fees still apply. Those on default tariffs may find fixed offers that provide greater certainty.

A fixed tariff is not automatically cheaper. It is an agreement to pay specified rates for a set period, rather than a guarantee of a lower total bill. The decision depends on the offered unit rates, standing charges, contract length, exit fee and expectations for future cap periods.

Compare annual costs using your own consumption rather than relying only on a supplier’s estimated monthly payment. It is also worth comparing payment methods, as rates can differ between Direct Debit, standard credit and prepayment arrangements.

Practical steps before winter heating demand peaks

The most effective response is not to stop heating the home or accept uncomfortable rooms. It is to reduce avoidable consumption while ensuring the system produces and distributes heat properly.

• Record meter readings: Take readings around the tariff change so usage at the old and new rates can be checked accurately.
• Review the heating schedule: Match operating times to the household’s routine rather than heating an empty property for long periods.
• Use room controls properly: Set a comfortable main thermostat temperature and use thermostatic radiator valves to avoid overheating lesser-used rooms. Do not turn every radiator off, particularly where doing so could create damp or freezing risks.
• Check boiler pressure: Follow the manufacturer’s instructions and investigate repeated pressure loss rather than continually topping up the system.
• Test the heating early: Run the system before the first cold spell. Check every radiator, listen for unusual noises and confirm that thermostats and programmers respond correctly.
• Reduce draughts: Seal appropriate gaps around doors and windows, but do not block purpose-provided ventilation, air bricks or appliance vents.
• Keep heat emitters clear: Avoid placing large furniture directly in front of radiators or covering them with heavy curtains.
• Maintain the boiler: Regular servicing supports safe operation and can identify deteriorating components, combustion issues or condensate problems before a winter breakdown.

Homeowners should be cautious about products promising dramatic savings from a single device. Boiler efficiency, heat loss, control strategy and occupant behaviour work together. Improvements are most effective when they address the actual weakness in the property rather than relying on a generic claim.

What homeowners across the local area should prioritise

In newer homes around Bordon and Whitehill, checking control settings and avoiding overheating may deliver more value than major system changes. Modern properties often retain heat well, but poorly programmed heating can still waste energy.

Older homes in Farnham, Alton and Haslemere may benefit from a broader approach combining appropriate insulation, draught management, balanced radiators and efficient boiler operation. In Liphook and surrounding rural locations, exposed pipework and external condensate routes also deserve attention before freezing conditions arrive.

The price cap cannot be controlled by an individual household, but the number of kilowatt-hours purchased can. Establishing accurate consumption, correcting heating faults and configuring controls properly are practical ways to limit the effect of the October increase without sacrificing safe, dependable heating.
