E3G, an independent climate change think tank, published a report on 23 October 2026 setting out eight "Essential Actions" it says would lower household and business electricity bills in Great Britain by approximately 20% by 20301. The report was produced with major contributions from members of the Electricity Bills Taskforce, and the call for the government to deliver the actions is backed by 20 organisations, including energy suppliers, business representatives, consumer advocates, academia and charities1.
E3G says only two of the actions can lower bills immediately: removing levies from bills and improving targeted support for households in fuel poverty and trade-exposed businesses1. It puts the cost of these two measures at roughly £10 to 11bn per year to 2030, tailing off each year, and says there is evidence that the economic boost from removing levies would outweigh the cost1. The report cites an anticipated 16% rise in Ofgem's energy price cap in January 2027 and says bills are not projected to fall again until the 2030s1.
The report's projections, powered by Cornwall Insight data and further analysis by the taskforce, show the eight actions lowering a projected typical household electricity bill in 2030 from £956 to £6411. The individual savings it attributes to each action in 2030 are set out below.
| Essential Action | Stated saving in 2030 |
|---|---|
| Move all levies from electricity bills to general taxation | £150 per household; 16% for businesses |
| Develop a strategy to reduce the cost of energy debt | £45 per household for everyone |
| Ensure network build is affordable and good value | £20 per household; 2% for businesses |
| Modernise how the system is operated faster | £20 per household; 3% for businesses |
| Enable consumer-led flexibility | £33 per household; 4% for businesses (spread across other areas) |
| Prevent excess profits in the wholesale market | £60 per household; 7% for businesses |
| Introduce better targeted support | £2bn extra; 3 million more households; £250 more per household |
| Create a minister-led process to ensure bills go down | Not quantified |

On levies, E3G says moving them to general taxation would cost roughly £8 to 10bn a year from now to 2030 but would deliver a £130bn boost of additional economic growth from now to 20501. On targeted support, it recommends paying an additional £2bn to support households in fuel poverty, supporting an extra 3 million households, up from 6 million today, with support increased by £250 per household1. It says removing levies for all businesses would support an additional 120,000 manufacturing businesses, relative to current plans to remove levies for only about 10% of this1.
"The real success will lie in government undertaking a comprehensive and concerted programme to deliver all 8 actions."
Why it matters for households
The report treats levies, which are policy costs recovered through electricity bills, as the largest single lever on a household bill, at £150 in 2030, and the only one alongside targeted support that can act in the short term1. For a household, the difference between the projected £956 and £641 figures is about a third of a typical annual electricity bill, though E3G says the potential for savings depends on the exact package the government puts together from its suggestions1. Several of the actions, including network reform and wholesale market change, would take years to affect what a home pays, which is why E3G argues for acting across each bill component now1. The report also links consumer-led flexibility, meaning use of electricity when it is cheap and plentiful, to lower costs for everyone, and says government must fill policy gaps to make the technology accessible and appealing1. The report does not set out changes to standing charges or to the price cap methodology itself.
What happens next
The report urges the government to fund the levy removal and targeted support this year, ahead of the full package by 2030, citing pressure on households and businesses from the conflict in Iran and rising gas prices1. It also recommends a minister-led process to expedite delivery of all eight actions1. No government response to the report has been reported.
