Energy Bills Summer 2026: Ofgem Price Cap, Unit Rates & How to Cut Costs
The Ofgem price cap for Q2 2026 (April–June) is £1,849/year for a typical household on direct debit. Unit rates, what drives changes, and practical ways to cut your bill before Q3 2026.
What is the Ofgem price cap?
The Ofgem energy price cap was introduced in January 2019 to protect households from very high variable tariff rates. It limits the maximum unit rate and standing charge that energy suppliers can charge customers on default (variable) tariffs.
Crucially, it is not a cap on your total bill — it's a cap on the rate per unit of energy. A household using more than average will pay more than £1,849.
The cap is reviewed quarterly and set based on:
- Wholesale energy prices: the cost suppliers pay for gas and electricity on the futures market
- Network costs: transmission and distribution infrastructure
- Operating costs and supplier profit allowance
- Levies: Warm Home Discount, smart meter rollout, etc.

The cap for April to June 2026 reflects further falls in wholesale gas prices compared to the 2022-23 crisis peaks, but remains elevated by historical standards.
| Component | Unit | Rate |
|---|---|---|
| Gas unit rate | per kWh | 6.04p |
| Gas standing charge | per day | 31.6p |
| Electricity unit rate | per kWh | 24.5p |
| Electricity standing charge | per day | 61.0p |
| Combined standing charges | per day | ~92.6p |
| Annual standing charges alone | per year | ~£338 |
Worked example: 3-bed home
A typical 3-bedroom semi-detached home in England uses approximately:
- Gas: 12,000 kWh/year (central heating + hot water)
- Electricity: 3,100 kWh/year (lighting, appliances, cooking)
Under Q2 2026 cap rates:
| Item | Calculation | Annual cost |
|---|---|---|
| Gas (energy) | 12,000 × 6.04p | £724.80 |
| Gas (standing charge) | 365 × 31.6p | £115.34 |
| Electricity (energy) | 3,100 × 24.5p | £759.50 |
| Electricity (standing charge) | 365 × 61.0p | £222.65 |
| Total | £1,822.29 |
This closely matches the Ofgem typical household estimate of £1,849 (slight regional variation applies).

Wholesale gas prices
Natural gas wholesale prices are the single biggest driver. Europe's gas storage levels, LNG import volumes, cold winters, and Russia-Ukraine war disruptions all affect the price. As of mid-2026, European gas storage is above average seasonal levels, putting downward pressure on the Q3 2026 cap.
Network costs
National Grid and regional distribution networks charge suppliers for transporting energy. These costs rise with infrastructure investment and are socialised across all consumers.
Policy levies
The Warm Home Discount, Renewables Obligation, and Contracts for Difference costs are bundled into bills. Renewables levies have risen as more offshore wind capacity comes online — partially offsetting lower gas costs.
Q3 2026 (July–September): what to expect
Cornwall Insight, the leading energy market analyst, forecast the Q3 2026 cap at approximately £1,700–1,800/year — a fall of £50-£150 from Q2. The main driver is lower wholesale gas prices following a mild spring across Europe.
However, the Q3 figure is not confirmed until Ofgem announces it — typically around 26 weeks before it takes effect, in late May.
How to cut your energy bill in 2026
1. Fix vs cap: compare tariffs now
Some suppliers are offering fixed-rate tariffs below the Q2 cap rate. A 12-month fix at, say, 23p/kWh for electricity and 5.8p/kWh for gas would save a typical household ~£80-100/year versus the cap.
However, locking in for 12 months risks paying above the cap if wholesale prices fall sharply in Q3 or Q4. Assess your risk tolerance and the duration carefully.
2. Claim the Warm Home Discount
The Warm Home Discount (WHD) provides a £150 automatic credit to eligible households' electricity accounts. In 2026, eligibility is based on whether your household data (held by DWP) matches qualifying criteria, including:
- Receipt of Pension Credit (Guarantee Credit)
- Receipt of certain means-tested benefits (Universal Credit, income-based JSA, ESA, etc.) AND being in a property with a high energy cost score
Check your eligibility at gov.uk — if you qualify, the credit is applied automatically and you don't need to apply.
3. ECO4 scheme: free insulation and heating
The Energy Company Obligation (ECO4) runs until March 2026 (with extension expected). It provides free or heavily subsidised:
- Loft insulation
- Solid wall, cavity wall, and underfloor insulation
- Air source heat pumps
- First-time central heating
Qualifying criteria: fuel poverty, receipt of means-tested benefits, or a property with EPC rating E, F, or G. Contact your energy supplier (large suppliers are obligated to offer ECO4) or use the Simple Energy Advice website.
4. Get a smart meter
Smart meters (available free from your supplier) let you track real-time energy use and often unlock time-of-use tariffs where overnight electricity is cheaper.
5. Shift to Economy 7 if you charge an EV or have storage heaters
If you charge an electric vehicle overnight, Economy 7 overnight rates of ~8-11p/kWh (versus 24.5p/kWh daytime) can save £400-600/year on charging alone for an average EV. You'll need a compatible meter and to shift large loads to overnight hours.
6. Simple behaviour changes (low effort, meaningful savings)
| Action | Estimated annual saving |
|---|---|
| Reduce thermostat by 1°C | ~£100-150 |
| Fix dripping hot tap | ~£20-40 |
| Shower 4 min vs 8 min (daily) | ~£75-100 |
| Switch to LED lighting (whole home) | ~£40-60 |
| Insulate hot water tank | ~£50-70 |
| Full dishwasher loads only | ~£15-25 |
| Turn off standby appliances | ~£30-50 |
7. Insulation: the biggest one-off saving
The Energy Saving Trust estimates:
| Insulation type | Typical annual saving | Typical cost | Payback |
|---|---|---|---|
| Loft (uninsulated → 270mm) | ~£150 | £300-600 | 2-4yr |
| Cavity wall | ~£200 | £500-1,000 | 2-5yr |
| Solid wall (external) | ~£300 | £8,000-15,000 | 25-40yr |
| Floor (ground level) | ~£60 | £500-1,500 | 8-25yr |
ECO4 makes loft and cavity wall free for qualifying households — the most cost-effective insulation to do first.
Prepayment meters: are you paying over the odds?
Since Ofgem equalised prepayment and direct debit rates in January 2023, prepayment customers are no longer penalised at the unit rate level. However:
- Many prepayment customers cannot easily access fixed tariffs (which can be cheaper than cap)
- Topping up in small amounts can lead to running out of credit at inconvenient times
- Smart prepayment meters can be switched to credit meters remotely — worth asking your supplier
If you're on a prepayment meter and eligible to switch, contacting your supplier to request a switch to a credit meter (and set up direct debit) can open up better tariff options.

Frequently asked questions
What is the Ofgem price cap in April–June 2026?
The Ofgem price cap for Q2 2026 (April to June 2026) is £1,849 per year for a typical household in England, Scotland and Wales paying by direct debit. This covers average usage of approximately 12,000kWh gas and 3,100kWh electricity.
What are the unit rates under the Q2 2026 price cap?
Under the Q2 2026 cap, typical unit rates are approximately 6.04p/kWh for gas and 24.5p/kWh for electricity. Standing charges are around 31.6p/day for gas and 61p/day for electricity — roughly 92p/day combined.
Will energy prices fall in summer 2026?
Cornwall Insight and other forecasters predicted the Q3 2026 (July–September) cap to fall to approximately £1,700–1,800/year, driven by lower wholesale gas prices. Nothing is guaranteed until Ofgem confirms the cap each quarter.
Does the price cap mean I pay exactly £1,849?
No — the cap limits the unit rate and standing charge Ofgem can set, not your total bill. If you use more than average you'll pay more; less than average and you'll pay less. £1,849 is the estimate for typical household usage.
What is the ECO4 scheme and who qualifies?
ECO4 (Energy Company Obligation) provides grants for insulation and heating improvements for households in fuel poverty or on certain benefits (Universal Credit, Pension Credit, Child Benefit etc.). Contact your energy supplier to check eligibility.
What is the Warm Home Discount in 2026?
The Warm Home Discount provides a £150 credit on electricity bills for eligible low-income households. It's applied automatically if you qualify — check gov.uk to see if you're eligible.
Are prepayment meter customers charged more?
Since Ofgem equalised rates in 2023, prepayment meters should be at the same unit rate as direct debit customers. However, topping up less frequently, or being unable to shop around for fixed tariffs, can mean prepay customers effectively pay more over time.
How do I find the cheapest energy deal in 2026?
With base rates falling, some suppliers are offering fixed tariffs below the current cap. Use Ofgem's accredited comparison sites (Uswitch, MoneySuperMarket) to compare. If a fixed deal is 5%+ below the current cap, it's worth considering.
What is Economy 7 and is it still worth it in 2026?
Economy 7 offers cheaper overnight electricity (typically 7-11pm to 6am) in exchange for a higher daytime rate. It's worth it if you can shift significant electricity use to night — typically storage heaters, overnight EV charging, or running appliances after 10pm.
How much can I save by improving insulation?
According to the Energy Saving Trust, a semi-detached house with uninsulated walls and loft could save £350–£600/year with full wall and loft insulation. Combined with an ECO4 grant (free for eligible households), the payback can be near-immediate.
