Electricity prices in the United Kingdom remain elevated relative to many European peers, even as the government moves to cut VAT on domestic electricity. BBC reporting notes that medium-use households paid the fourth-highest prices in the European Union during the second half of the previous year, despite policy efforts to ease bills. The article outlines three core factors behind the higher cost of power in the UK, each supported by data and expert interviews.
First, wholesale gas prices continue to heavily influence electricity costs. The price generators bid for electricity, and even when gas-fired plants represent a small share of generation at a moment in time, they can set the marginal price that determine the wholesale rate paid to all generators. Gas-fired plants face higher input costs because they must procure fuel and cover emissions charges, known as a carbon price. The result is that fluctuations in gas markets tend to feed into consumer bills. The piece also notes that geopolitical tensions around Iran and Ukraine have added pressure to gas prices.
Second, the UK’s energy mix differs from some other large economies. Analysts point to the relatively large share of electricity produced from natural gas versus others that rely more on nuclear or renewables. In 2025, about 31% of UK electricity came from natural gas, compared with much lower shares in some European peers. By contrast, France generated about 69% of its electricity from nuclear power, and the United States generates a larger gas share than the UK but benefits from lower wholesale gas prices due to shale gas production.
Third, infrastructure and policy costs are shaping bills. The UK is expanding and modernising its electricity grid to accommodate wind and solar, which has raised network costs paid by consumers. The wholesale energy costs contribution to a typical Great Britain bill rose from £311 in 2024-25 to £320 in 2025-26, while network costs climbed from £136 in 2019-20 to £250 in 2026. Analysts say underinvestment in the prior decade required substantial and ongoing capital spending to catch up. The article highlights that policy costs tied to subsidies for wind and solar generation and grid investments are also embedded in bills, though some policymakers argue these costs should be funded through general taxation rather than customer bills to avoid discouraging electricity use over gas for heating.
Analysts quoted in the piece stress that future wholesale gas prices are difficult to forecast, making it challenging to predict exactly how bills will evolve. There is also debate over the structure of cost allocation—whether policy costs should be visible on bills or absorbed through taxation or other charges.
The BBC notes that the government has announced a VAT cut on domestic electricity this October from 5% to zero in an effort to ease cost of living pressures, but households will still be balancing multiple price drivers in the near term.
