- Period: October 1, 2026 to March 31, 2027 (6 months).
- Scope: All domestic electricity bills, including those under the price cap.
- VAT change: 5% to 0%.
- Gas bills: VAT remains at 5%.
- Benefit: approximately £32/year savings on electricity bills for a typical household using 2,500 kWh/year.
The VAT removal partially offsets the cap increase. Net effect for a typical direct-debit household: £60 cap increase - £32 VAT savings = £28 net increase (£2.33/month) (UK Treasury; Ofgem, 2026).
How to switch UK energy supplier
Switching is fast, free, and typically saves £100-£200/year for SVT customers:
- Get your current usage: check your last 12 months of bills or request a usage statement from your current supplier.
- Use a comparison site: MoneySupermarket, Compare the Market, uSwitch, or Citizens Advice Price Comparison tool.
- Compare fixed tariffs: 12-month fixed rates are typically 4-8% below SVT (Ofgem data).
- Consider exit fees: check if your current fixed tariff has exit fees (most modern fixes have no exit fees).
- Switch via your new supplier: the new supplier handles the entire switch; takes 17-21 days.
- Auto-switching services: services like Look After My Bills or Switchcraft automatically switch you when a better deal is available.
Special considerations:
- Prepayment meter customers: PPM rates are higher than direct-debit; switching to direct-debit saves more.
- Economy 7 customers: ensure the comparison site handles your time-of-use tariff correctly.
- Smart meter customers: may qualify for cheaper off-peak rates (varies by supplier).
- Vulnerable customers: the Warm Home Discount (£150-£300 rebate) and Cold Weather Payment (£25/week during cold periods) apply regardless of supplier.

UK energy market context
The UK energy price cap is a regulatory tool introduced by Ofgem in January 2019. Key facts:
- Protects 22 million households on default tariffs (Standard Variable Tariff).
- Reviewed quarterly (February, May, August, November).
- Based on typical domestic consumption values (TDCVs): 2,500 kWh electricity, 9,500 kWh gas.
- Updated TDCVs July 2026: reflecting 7% less electricity and 17% less gas consumption due to energy efficiency improvements, warmer weather, and higher prices.
- Wholesale allowance = 47% of cap: the largest single cost component.
Customers on fixed-rate tariffs are protected from quarterly cap changes for the duration of their fix. The cap does not apply to commercial energy customers (Ofgem, August 26, 2026).
What to expect through 2027
| Period | Expected cap change | Drivers |
|---|
| Oct-Dec 2026 | +4% (confirmed) | Wholesale gas prices; Middle East tensions |
| Jan-Mar 2027 | +3 to +7% (forecast) | Winter heating demand; continued Middle East impact |
| Apr-Jun 2027 | -2 to +2% (forecast) | End of winter; potential wholesale easing |
| Jul-Sep 2027 | +1 to +4% (forecast) | Summer cooling; geopolitical uncertainty |

Annual average energy bill for a typical household could reach £1,750-£1,850 in 2027 if forecasts hold - the highest sustained level since the 2022 energy crisis peak.
FAQ
Does the UK energy price cap affect all UK households?
The cap applies to standard variable tariff (SVT) customers in England, Scotland, and Wales - approximately 22 million households. Customers on fixed-rate tariffs are protected for the duration of their fix. Northern Ireland has separate Northern Ireland energy price cap arrangements. Commercial and industrial customers are not covered by the cap - they negotiate rates directly with suppliers (Ofgem, 2026).
Can energy suppliers charge more than the cap?
No. The Ofgem cap is the maximum amount suppliers can charge per unit rate (p/kWh) and per standing charge (p/day) for SVT customers. Suppliers cannot exceed these rates. If a supplier charges more, customers can complain to Ofgem and the supplier can face enforcement action. Fixed tariff suppliers may offer rates below the cap but cannot exceed it for the SVT portion of their business (Ofgem, 2026).
Will the UK government do more to help with energy bills?
The VAT removal (Oct 2026 - Mar 2027) is the current support measure. The government could extend it in the March 2027 Budget if energy prices remain high. Additional measures under consideration: Energy Price Guarantee (capping bills at a fixed level per household, similar to the 2022-2023 Energy Price Guarantee), additional Warm Home Discount expansion, or targeted support for vulnerable customers. The Chancellor has stated the government will 'respond proportionately' to the energy situation (UK Treasury, 2026).
