UK Energy Bills 2026 — Gas and Electricity Price Cap Explained

Energy bills remain one of the biggest financial pressures on UK households. Although they have fallen from the extreme highs of 2022–23, they are still far above where they were before the energy crisis — and the Ofgem price cap has risen again in 2026. Here is everything you need to know.

What is the Ofgem price cap?

The Ofgem price cap does not set a maximum total bill — it limits the unit rate and standing charge that suppliers can charge domestic customers on default (variable) tariffs. Your actual bill depends on how much energy you use. Ofgem updates the cap quarterly based on wholesale energy market prices.

The "typical household" figure Ofgem uses assumes annual consumption of 2,900 kWh of electricity and 11,500 kWh of gas. Actual usage — and therefore bills — varies significantly by property size, insulation, heating system and household size.

How the cap translates to unit rates

What the cap means in practical terms for a typical dual-fuel direct debit customer:

• Electricity unit rate: approximately 24–25p per kWh
• Electricity standing charge: approximately 61p per day
• Gas unit rate: approximately 6–7p per kWh
• Gas standing charge: approximately 32p per day

Standing charges alone add up to roughly £340/year before a single unit of energy is consumed — a source of significant frustration for households that use very little energy.

How much more are we paying than in 2020?

Before the energy crisis, the typical annual bill sat at around £700–£800. At the current cap level of £1,849, households are paying more than double what they were just five years ago. Even at the 2024 low of £1,568, bills remained roughly double pre-crisis levels.

Fixed tariffs vs the price cap

When the price cap is expected to fall, staying on a variable tariff tracks those reductions automatically. When wholesale prices are rising — as they have been again in 2025–26 — locking in a fixed tariff before cap rises can make financial sense.

• Use a comparison site (Uswitch, MoneySupermarket, Energy Guide) to compare fixed deals against the current cap rate
• Check the unit rate and standing charge, not just the headline annual figure — your usage may differ from the "typical household" assumption
• Fixed deals often come with early exit fees, so factor that in if your circumstances might change

Practical ways to reduce your energy bill

Reducing consumption is the most direct way to cut costs regardless of which tariff you are on:

• Heating — dropping your thermostat by 1°C reduces heating costs by around 10%. A programmable or smart thermostat pays back quickly
• Hot water — set your boiler's hot water temperature to 60°C (the minimum safe level to prevent legionella) rather than higher
• Washing machine and dishwasher — use 30°C or 40°C cycles and run full loads. Avoid heat-dry settings on dishwashers
• Standby — devices left on standby can account for 5–10% of a typical electricity bill
• LED bulbs — if you haven't already switched, LED bulbs use 75–80% less electricity than traditional incandescent bulbs
• Draught-proofing — one of the cheapest home improvements with the fastest payback

Support schemes available

If you are struggling with energy costs, several support mechanisms exist:

• Warm Home Discount — £150 off your electricity bill if you are on certain means-tested benefits or have a low income. Applied automatically for most eligible households
• Winter Fuel Payment — available to those born before a certain date; eligibility rules have changed, so check GOV.UK for current criteria
• Cold Weather Payments — £25 for each 7-day period of very cold weather if you receive certain benefits
• Energy company hardship funds — most major suppliers operate funds for customers in genuine difficulty; contact your supplier directly
