Several leading UK energy suppliers have pledged to pass on significant cost savings to customers following new measures introduced in the latest Budget. The policy changes, which include the removal of certain levies from household energy bills and a shift of costs into general taxation, are expected to reduce average annual bills by approximately £150.


The government has emphasised that these savings should benefit all customers, including those on fixed-rate contracts, putting pressure on suppliers to ensure transparent and full implementation.

New Policy Measures to Reduce Household Energy Bills

Chancellor Rachel Reeves announced in the Budget a package aimed at easing the burden on households facing high energy costs. Key measures include the abolition of the Energy Company Obligation (ECO) scheme levy from customer bills and transferring three-quarters of the cost of subsidies for older renewable energy projects (the renewables obligation) from electricity bills to general taxation.


According to statements made during the Budget, these steps, combined with related VAT adjustments, are intended to yield average annual savings of approximately £154 per household. The government has positioned these changes as an important part of efforts to support families amid ongoing cost-of-living challenges.

Government's Expectations for Energy Providers

Following the Budget, Energy Secretary Ed Miliband wrote to suppliers, underscoring the government’s 'clear expectation' that all savings from these policy amendments are fully reflected in customers’ bills.


He insisted that this commitment must extend to households with fixed-term energy contracts, despite these agreements usually being set at predetermined rates. The government’s directive aims to prevent discrepancies among energy customers and to ensure that the intended relief from policy changes is accessible and equitable.

Leading Suppliers Confirm Bill Reductions

A number of the UK’s largest energy firms have confirmed they will automatically apply the savings to both variable and fixed-rate tariffs starting from 1 April.


Octopus Energy, currently the country's largest supplier by customer numbers, announced that its customers will see reductions with no action required on their part. Greg Jackson, CEO and founder of Octopus Energy, commented, 'These changes will bring welcome relief to customers, and we’ll pass them through on all of our tariffs as soon as they kick in, so no one misses out.' Other major energy providers, including E.ON Next, British Gas, OVO, and EDF, have issued similar commitments.


Each company stated it will ensure the announced savings are automatically reflected in all customer bills. E.ON Next stated, 'When these savings start in April, we’ll pass them on in full to all our customers. No ifs. No buts. No small print.'

Fixed-Rate and Variable Tariff Customers Included

A prominent aspect of the government’s guidance is the inclusion of customers on fixed-term contracts in these price reductions. British Gas confirmed it would ensure those on fixed-rate tariffs benefit as well as variable tariff customers, closing potential gaps that could have left some households excluded.


ScottishPower indicated it is working with the government to clarify details and is planning for both fixed and variable customers to receive the reductions from 1 April.


OVO and EDF similarly confirmed their intention to pass through the savings, noting that further detail would be provided as implementation plans are finalised with the government and energy regulator Ofgem.

Industry and Consumer Response

Consumer campaigner Martin Lewis has been vocal in urging all energy firms to clarify how the reductions will be applied. Lewis explained that households could expect about a 3.5p per kilowatt hour, or 13 percent, decrease in electricity prices, and a 0.35p per kilowatt hour, or 6 percent, decrease in gas prices, assuming other variables remain unchanged.


However, Lewis highlighted that energy costs are subject to fluctuation, stating that actual savings may differ due to expected increases in the April price cap. He estimated the likeliest reduction would equate to around 6 percent compared to January’s rates, if current forecasts hold.

Final Summary

The latest policy changes signal a coordinated effort by the government and the UK’s largest energy suppliers to address the financial strain of high energy bills. Major providers have confirmed that both fixed and variable tariff customers will receive the £150 annual savings, beginning in April.


Ongoing discussions between companies, the government, and the regulator are expected to settle any remaining operational concerns. As households prepare for these reductions, the Pie app remains a useful resource for tracking personal finances and navigating cost-of-living changes.
