The Energy Price Cap Guide 2026 is essential reading for UK households facing rising energy costs. Ofgem sets the price cap every three months to limit what suppliers can charge on standard variable tariffs (default tariffs). It doesn’t cap your total bill—your usage determines that—but it protects against excessive unit rates and standing charges.
Latest Energy Price Cap Update for July–September 2026
From 1 July to 30 September 2026, the energy price cap for a typical dual-fuel household paying by Direct Debit rises to £1,862 per year. This marks a 13% increase (around £221 more) from the April–June 2026 level of £1,641.
Key rate changes (averages for Direct Debit payers in England, Scotland, and Wales, including 5% VAT):
- Electricity: 26.11p per kWh (up from 24.67p); standing charge ~57.19p per day.
- Gas: 7.33p per kWh (up from 5.74p); standing charge ~29.04p per day.
Note: Rates vary by region, payment method, and meter type. Prepayment meter customers face a different cap (around £1,812 for typical use), while quarterly payers or standard credit see higher figures (up to ~£2,005).
Ofgem uses updated Typical Domestic Consumption Values (TDCV) from July 2026, reflecting lower average household usage (e.g., electricity ~2,500 kWh/year and gas ~9,500 kWh/year in newer models).
Why Is the Price Cap Rising in 2026?

Many fixed deals available now are cheaper than the new capped rates. Switching could save you hundreds of pounds. Use comparison tools carefully (some hide the best deals) and consider Martin Lewis’s advice on MoneySavingExpert for finding hidden tariffs.
Pro tip: Even if you’re in credit on your Direct Debit, request a refund or adjustment before switching. Direct Debit remains one of the cheapest payment methods under the cap.
