The History of Ofgem’s Energy Price Cap

There is currently an Energy Price Cap managed by the industry regulator Ofgem that caps the price of electricity for an average user of gas and electricity. The unit rates and standing charges change quarterly.

What are the current energy price cap rates?

Current energy price cap rates 1st October 2025 – 31st December 2025

• Average dual fuel bill: £1,755 (+2.1%)
• Electricity unit rate: 26.35p/ kWh (+2.4%) plus 53.68p/ day (+4.5%)
• Gas unit rate: 6.29p/ kWh (-0.6%) plus 34.03p/ day (+14.1%)

Previous energy price cap rates 1st July 2025 – 30th September 2025

• Average dual fuel bill: £1,720 (-7.0%)
• Electricity unit rate: 25.73p/ kWh (-4.8%) plus 51.37p/ day (-4.5%)
• Gas unit rate: 6.33p/ kWh (-9.4%) plus 29.82p/ day (-8.7%)

Rates vary by region with East Midlands the cheapest, and North Wales the most expensive.

When is the next energy price cap change?

Ofgem review the charges each quarter. Below are the next reporting dates:

• 25th November 2025 – period 1st January 2026 to 31th March 2026
• 25th February 2026 – period 1st April 2026 to 30th June 2026

What is the energy price cap and when was it introduced?

An energy price cap limits the maximum price that a supplier can charge its customers per unit of energy used. It also sets a maximum daily standing charge (the cost of connecting your home to the national grid). However, the price cap never limits your total energy consumption; if you use more, you pay more than the set limit. The set rates were introduced in January 2019 by regulatory body, Ofgem, and reviewed every six months.

Why was it introduced, and how does the energy price cap work?

Ofgem introduced the cap to help homeowners avoid having to fork out on extortionate bills, and to prevent suppliers from making excessive profits from consumers. There is no price cap in place to fix business electricity rates in the UK. In addition, the rate intended to limit costs associated with the most expensive rates on standard and default variable tariffs.

However, as market prices soared, rate differentials narrowed on the whole, giving homeowners no clear cheaper option — exposing the first flaw of the cap: when prices go up, the cap rate follows.

What does the latest cap increase mean for households?

The latest change means your energy prices will rise if you’re on a variable tariff. Fixed-priced tariff customers are unaffected until their deal expires. Below are the current and previous energy price cap rates.

The cap decreases are largely as a result of lower wholesale energy costs. Wholesale energy prices are lower as a result of global and local issues. Moving into the summer months usually sees a reduction in energy prices due to lower demand.

Previous issues closer to home include lower wind levels, which have led to lower renewable energy generation. An outage at a National Grid site in Kent knocked out a power cable that runs between England and France. The UK also has some of the lowest gas reserves in Europe, which means there is almost no way of stockpiling gas to use when needed.

The cap accounts for both fuels, but respectively, gas costs have increased by 81% whereas electricity rates have jumped by 36%. Around 23 million homes in the UK are heated by gas boilers, favoured as the cheaper, more convenient option. The changing cap rates could trigger a shift amongst homeowners though, and many may consider switching to electric heating.

While there might be savings to be had in the long run by changing to electric heating, there are still initial expenses that won’t amount to any significantly lower monthly bills than the figures we can expect to see from the new capped gas rate.

For homeowners who want to make the change, investigating tariff options is key. On certain tariffs, and depending on when you use your heating, savings may be possible. However, customers are once again stuck with no clear advantage — over time and because of market climate and future cap rates, bills may not stray much at all from the proposed new figure.

With genuine concern around the rise of fuel poverty, various government-backed rebate schemes were actioned. These are detailed below.

The Ofgem energy price cap history & timeline

Throughout the energy price cap history, no rate increase has taken as steep of an incline as the April 2022 announcement.

Notes: Data correct as of 2nd October 2025 and rounded to two decimal places. The total bill calculation takes average usage data from Ofgem. These were 3,100kWh for electricity and 12,000kWh for gas in January 2019. In 2025, the usage figures have reduced to 2,700kWh and 11,500kWh, respectively. The October 2025 price cap is 54% higher than the January 2019 launch. However, using the original usage figures shows the actual increase is 62%.

Critics of the price cap have called it a ‘halfway house’ of sorts, serving only a niche group of consumers and the governing bodies which have enacted it. It could be argued that the cap has distorted the market, based on the fact that when the cap was first introduced, prices fell dramatically between April 2019 and October 2020. When the price cap rose in January 2021, the cheapest market deals weren’t far off the capped rate of £1,138. These unrealistically low prices supported the agenda that customers were getting a good deal, and now that prices have soared, the price cap simply follows.

Should the cap remain in place?

Cap rates have taken customers on a rollercoaster ride — even if a household uses less energy, they’re still roped into paying the daily rate, while suppliers have created the perception that fair deals do exist. Without the cap, regulatory bodies and governments could once again be faced with the issue of tackling providers profiting excessively from bill payers. As we veer towards a crisis in cost of living, with or without a price cap in place, authorities would have to find substantial ways to cushion households from the looming rate hike.

Government Energy Rebates

In addition to the price guarantee, various government credits supplemented consumer bills.

• £200 credit per meter if you used an alternative fuel to gas (for example, LPG, Oil) – credited February 2023.
• £400 energy bills support scheme per meter – credited over six months from October 2022.
• The Energy Price Guarantee restricted average bills to £2,500 between October 2022 to June 2023.

A winter fuel payment for people of pensionable age also continued until the winter of 2024.

Energy Price Cap FAQs

Is there an energy price cap for businesses?
There is no energy price cap in place for business users, although prices are usually similar to domestic gas and electricity tariffs. There was an Energy Bill Relief Scheme and an Energy Bills Discount Scheme for businesses during the highest prices, but these finished in March 2024.

Should I switch suppliers before the new energy price cap rates begin?

Despite the fact that switching tends to help customers avoid price hikes and secure better deals, the nature of the market means that there’s no guarantee of savings. If you’re still keen to switch, consider how much costlier a new tariff would be than your current rates and factor in the average amount of time it takes to switch — typically, 17 days.

What happens if my current energy supplier goes bust?

Ofgem has a responsibility as a regulatory body to protect customers from unforeseen circumstances, such as in the event a provider enters liquidation. Your energy supply will not be interrupted in this occurrence.

Is the cap likely to change again in 2025?

Cornwall Insight are anticipating further price changes as wholesale energy costs remain volatile, though this is not certain. Wholesale prices depend on the market and levies on firms, and Ofgem has no control over these aspects.
