The UK Energy Research Centre (UKERC) published a briefing paper on 28 July 2026 examining the drivers of high domestic electricity bills, the expected trajectory of bill components through 2030, and the policy and market reforms that could reduce costs for UK households1.
The paper reports that average annual domestic electricity bills have grown in real terms from £643 to £968 over the last decade, driven by wholesale, network, operating and policy costs1. Gas-linked wholesale prices are described as the most volatile component, spiking by 381% between 2021 and 2023 following Russia's invasion of Ukraine1. UKERC states that government moved a proportion of policy costs from electricity bills to general taxation in April 2026, delivering a reduction of approximately £100 per household, but adds that the escalating conflict in the Persian Gulf has already overwhelmed much of this progress1.
On the outlook, the paper says network costs are set to rise in the short to medium term because of substantial investment in maintaining and expanding networks, while wholesale costs are expected to fall with increasing renewable energy capacity under a fixed price contract1. It argues that high gas dependence, low gas storage and the strong link between gas and electricity prices leave both gas and electricity bills particularly vulnerable to fossil fuel price volatility, and that individual fossil fuel energy crises each have the potential to be more expensive for the UK than the transition to net zero by 20501.
The paper sets out several areas of focus for reducing bills, including shifting remaining policy costs into general taxation, which it says could reduce bills by as much as 10%, and a tiered standing charge as fixed costs continue to rise1. It also points to reform of system costs driven by constraint and curtailment, stronger consumer-led flexibility, and accelerating electrification to spread fixed costs across growing demand1. UKERC says the influence of gas on electricity prices is already weakening and will be further aided by recently announced government plans, but that more ambitious proposals closer to its Pot Zero plan could deliver substantially greater reductions1.
"This UKERC Briefing Paper provides an analysis of the drivers behind high electricity bills, the expected trajectory of bill components through 2030, and the policy and market reforms that could meaningfully reduce costs for UK households."
| Measure discussed in the paper | Stated effect |
|---|---|
| Policy costs moved to general taxation, April 2026 | Reduction of approximately £100 per household1 |
| Shifting remaining policy costs into general taxation | Could reduce bills by as much as 10%1 |
| Tiered standing charge | Described as a more progressive approach to cost recovery as fixed costs rise1 |
Why it matters for households
The paper's central point for a household is that the bill is made up of parts that move for different reasons. Wholesale costs track gas and have proved the most volatile element, while network costs are expected to rise as investment continues1. That means a fall in one component does not necessarily produce a lower total bill, as the paper's account of the April 2026 policy cost shift and the subsequent Gulf conflict illustrates1. The paper also links the price of electricity relative to gas to the case for heat pumps and electric vehicles, noting that wider adoption would be supported by action to reduce electricity prices relative to gas1. For a home weighing its exposure to fossil fuel price swings, the paper frames the gas-to-electricity price link, and the fixed costs recovered through standing charges, as the levers that determine how much control a household has over what it pays. UKERC states that most of the UK public still supports the push to renewable energy and net zero, but that support for the 2050 timeline has weakened in recent years1.
What happens next
UKERC describes the briefing as laying a foundation for subsequent work to explore specific options and a package of reforms1. A press release on the report is dated 29 July 2026, and a parliamentary roundtable write-up is dated 28 July 20261. No implementation dates for the reforms discussed have been reported1.
