What is the Domestic Energy Price Cap in the UK?
The UK energy domestic price cap is the maximum amount energy suppliers can charge you for your gas and electricity consumption, either per unit of energy or as a standing charge. Unlike business energy tariffs, the cap applies to domestic households and is designed to protect consumers from sudden and excessive increases in energy costs.
This price cap is based on the average dual consumption (gas and electricity) for a typical household paying via direct debit. For those on a standard variable tariff, the cap is made fair by aligning energy prices with the average unit price. However, your rate will vary depending on where you live, how you pay and the type of meter you have.
To ensure you’re covered by the domestic energy price cap in the UK, you must pay for gas and electricity by either:
- Standard credit
- Direct debit
- Prepayment meter
- Economy 7 (E7) meter
Therefore, the domestic UK energy price cap is not necessarily a cap on what you pay but a limitation on the price of energy you use. In other words, if you use more energy, you’ll still pay more despite the cap.
What is the Current Domestic Energy Price Cap in the UK?
Following a recent energy price cap reduction in the UK, Ofgem announced that, between April and the end of June, the domestic UK energy price cap is set at £1,641 per year for a typical household. Compared to the domestic UK energy price cap in Q1 (January through March), that amounts to a 6.6% decrease.
The current domestic energy price cap in the UK per unit and daily standing charge includes the following:
Electricity - 24.67p per kWh - 57.21p daily standing charge
Gas - 5.74p per kWh - 29.09p daily standing charge
Compare Q2 with Q1 in 2026:
Electricity - 27.69p per kWh - 54.75p daily standing charge
Gas - 5.93p per kWh - 35.09p daily standing charge
The amount is based on an average for typical households across England, Scotland, and Wales that pay by direct debit, including a 5% VAT, with all figures rounded to two decimal places.
What Can Cause the Domestic UK Energy Price Cap to Change?
Multiple variables can influence the domestic UK energy price cap to change. As we saw in Q1 and Q2, with the overall cap decreasing, it can go either way depending on multiple factors:
These factors include:
- Wholesale costs (Suppliers purchasing energy for customers)
- Network maintenance costs
- Supplier business costs
- Changes to policies (Government, social, environmental, etc.)
- EBIT Allowance (Earnings Before Interest and Taxes)
- Uncertain costs and risks
- Levelisation allowance (Ensuring prepayment and direct debit charges are equal)
- VAT (5%)
In Q2 2026, changes to the current domestic energy price cap in the UK have been influenced positively, with two environmental and social schemes funded through general taxes from April 2026, helping customers save around £150.
Other changes include the Warm Home Discount moving from standard charges to a unit rate, with global wholesale energy prices decreasing by an overall £38 per year.
However, some network costs have increased by £66 based on the current price control framework (RIIO-3). This investment in infrastructure is seen as an essential upgrade for stabilising future energy prices.
Will the Domestic UK Energy Price Cap Change in Q3 2026?
Ready to be announced on the 27th May, 2026, the domestic UK energy price cap for Q3 of 2026 is expected to rise significantly due to rising wholesale costs. Much of this rise in UK wholesale energy prices has been influenced by the Middle East conflict and other geopolitical issues.
Because energy suppliers purchase energy in advance, unfortunately, the recent increases in wholesale prices are likely to feed into the next price cap period.
