How Energy Suppliers React to the Energy Price Cap

The energy price cap, set by Ofgem, is crucial for the UK energy market. It controls how much energy companiescan charge domestic customers for each unit of energy. This cap helps protect direct debit customers, users of prepayment meters, and those on a standard variable tariff. However, it also has a big impact on energy companies.

Energy suppliers need to handle wholesale energy prices, network costs, and operational costs. They have to do this while keeping within the price cap limits.

How the Energy Price Cap Affects Energy Suppliers

The energy regulator, Ofgem, updates the current price cap four times a year: in January, April, July, and October. This change depends on several factors. These are wholesale prices, network costs, and customer service obligations.

Key Effects on Energy Suppliers:

Revenue Constraints

  • The price cap level sets a maximum amount energy suppliers can charge for each unit of energy. This rule makes it difficult for them to earn more when wholesale prices rise.
  • Suppliers cannot easily pass on the changes in wholesale energy prices to customers on standard variable tariffs. This creates financial pressure on them.
  • They still have to pay for costs like network costs, standing charges, and customer service expenses. This lowers their profit margins.

In the last part of 2023, many suppliers had issues. This happened because wholesale energy prices went up. At the same time, the price cap limited how much they could charge.

Year Price Cap Level (£ per year, average household) Wholesale Market Cost Share
2022 £1,277 55%
2023 £1,834 60%
2024 £1,717 50%

As wholesale prices rise and fall, energy suppliers must manage their risks. This could lead to higher fees or the removal of certain rates.

Impact on Energy Tariffs

  • A lot of suppliers have reduced their energy rates. There are now fewer fixed-rate options available.
  • Discounts for dual fuel plans used to be easy to find. Now, they are rare due to efforts to save money.
  • Some suppliers now provide time-of-use tariffs. These plans tell customers to use energy during off-peak hours.

The energy market used to offer many different tariff options. Now, since Ofgem added the price cap, there are fewer choices available.

Tariff Type Availability Before Price Cap (2018) Availability in 2024
Fixed Tariffs High Limited
Dual Fuel Tariffs Common Less Common
Green Tariffs Growing Trend Still Available
Time-of-Use Tariffs Limited Expanding

The reduction in tariff options has made switching suppliers tougher. It has also narrowed down choices for consumers.

Financial Struggles and Market Exits

  • Since 2021, more than 30 energy suppliers have stopped working. They could not manage the rising wholesale prices while keeping to the energy price cap.
  • Smaller suppliers have been affected the most. They do not have enough resources to deal with energy costs.
  • The Supplier of Last Resort (SoLR) plan has made larger companies like British Gas, Octopus Energy, and E.ON accept these lost customers.

Reduced Investment in Energy Efficiency Measures

  • A lot of energy companies are reducing their funding for energy efficiency measures. They have less money coming in now.
  • In the past, suppliers supported home insulation grants and smart meter installations. Now, some are decreasing their help with these programs.
  • Investments in renewable energy incentives are slowing down. Companies are now focusing more on staying financially stable.

Impact on Government-Supported Energy Efficiency Programs

Scheme 2020 Supplier Contributions (£m) 2024 Contributions (£m)
Energy Company Obligation (ECO) £640 million £450 million
Smart Meter Installations £1.2 billion £950 million
Renewable Incentives £300 million £180 million

This drop in energy efficiency investments might mean that homes and companies will save less energy over time. Because of this, their bills could be higher in the future.

Impact of the Energy Price Cap on Energy Supplier Profitability

Breakdown of Supplier Costs (2024 Price Cap Cycle)

Cost Component Percentage of Average Bill
Wholesale energy costs 50%
Network costs (transmission, distribution) 20%
Operating costs (customer service, metering) 10%
Environmental/social obligations (renewable schemes) 8%
VAT & other costs 5%
Profit Margin 7%

Wholesale energy prices make up the largest portion of costs for energy suppliers. When these costs rise significantly, like in the energy crisis, it becomes tough for suppliers to remain profitable due to price cap limits.

How Energy Suppliers Adapt to Price Cap Changes

1. Adjusting Tariff Offerings

Before the price cap, energy suppliers offered many different plans, like fixed-rate deals. Now, many of them have reduced their options to:

  • Default tariffs (SVTs) – These have a limit set by Ofgem’s energy price cap.
  • Dual fuel tariffs – Some suppliers offer discounts when you pay your gas and electricity bills together.
  • Time-of-use tariffs – The goal is to encourage you to use energy during off-peak times.

2. Reducing Operational Costs

Some suppliers have found ways to handle the limits on income by:

  • Cut down the number of customer service teams. This made wait times longer.
  • Began using automation and online-only billing for direct debit customers.
  • Hired outside help for some tasks to save money.

3. Passing on Costs to Consumers

Suppliers must stick to the price cap limits. But some of them have increased their standing charges. This means that bills might be higher, even though the unit rates are capped.

Standing Charges Comparison (April 2024) Electricity Gas
Direct Debit Customers 60.99p/day 31.66p/day
Prepayment Meter Users 63.5p/day 34.5p/day

4. Managing Wholesale Price Volatility

Suppliers try to keep energy costs steady by:

  • Hedging strategies – This means buying energy before it’s needed. It helps you avoid sudden price changes.
  • Diversification – This means investing in renewable energy. It helps reduce dependence on changes in the wholesale market.

Energy Supplier Struggles and Market Exits

The UK is experiencing an energy crisis. This is happening because wholesale energy prices are rising. As a result, many energy suppliers have had to shut down. Since 2021, over 30 suppliers have exited the market because of this problem.

  • Cannot raise prices for consumers due to price cap limits.
  • Face high operating costs and have low cash savings.
  • There are big changes in the cost of energy from global markets.
Major Supplier Failures (2021–2024) Date of Collapse Number of Affected Customers
Bulb Energy November 2021 1.6 million
Avro Energy September 2021 580,000
Green Supplier Ltd September 2021 255,000

Big energy companies, such as British Gas, EDF, and E.ON, have welcomed customers from companies that went out of business. They did this through the Supplier of Last Resort (SoLR) plan. But these changes have led to higher costs for the other suppliers.

How Energy Suppliers Are Preparing for the Next Price Cap Changes

The next price cap updates will be in April 2025. These updates will determine if suppliers have to change their pricing plans again.

Predictions for Future Price Caps

  • The wholesale price volatility will probably continue to affect unit rates.
  • There could be changes in standing charges aimed at helping suppliers’ income.
  • Greater focus will go to renewable energy investments to maintain stable pricing in the future.
Price Cap Levels Over Time (Average Household Bill) Annual Cost
October 2023 – December 2023 £1,834
January 2024 – March 2024 £1,928
April 2024 – June 2024 £1,717
July 2024 – September 2024 Projected £1,765
