Three reasons why UK electricity prices are so high

By Ben Chu , Policy and analysis correspondent  and  Anthony Reuben , BBC Verify Published 13 minutes ago While the UK government has announced it will cut VAT on domestic electricity this October from 5% to zero in an attempt to help with the cost of living, British households are still paying more for power than many other European nations. Comparing UK prices with the EU shows that medium-use households here paid the fourth-highest electricity prices in the second half of last year including taxes and levies, although the government has taken steps to reduce bills since then. Here are three key reasons why British electricity prices are high. 1. The cost of wholesale gas often sets the electricity price The price energy suppliers pay for electricity is set by a bidding process with each generating company saying what it would be willing to accept to produce one unit of electricity. Once built, the cost of generating power from renewables like wind and solar is relatively low, so these typically come in with the cheapest bid. Nuclear might come next. Gas generators often have the highest costs because they have to buy fuel to generate electricity as well as paying a "carbon price" - a charge for emissions. The wholesale cost is set by the last unit of electricity needed to meet demand from consumers. This means that even if gas only generates 1% of overall electricity at a given time it can often set the overall wholesale price which gets paid to every type of generator. That raises prices for households - particularly because the wars in Iran and Ukraine have increased the cost of gas. Northern Ireland operates on a separate system to the rest of the UK, being part of the Single Electricity Market with the Republic of Ireland. 2. Other countries have a different energy mix Analysts say that one of the reasons why electricity prices are higher in the UK than some other countries is because we generate a relatively high share of our electricity from natural gas. In 2025 31% of the UK's electricity was produced from burning natural gas. This compares with just 3% in France, which generated the majority of its electricity - 69% - from nuclear power. The US has a higher share of natural gas in its electricity generation mix than the UK - 40% - but American wholesale gas prices are considerably lower thanks to the shale gas production boom of the past 20 years. 3. The UK is building much more electricity grid infrastructure Higher wholesale gas prices have pushed up UK domestic electricity bills this year. The wholesale energy costs contribution to a typical household bill in Great Britain rose from £311 in 2024-25 to £320 in 2025-26. But bills have also been pushed up in recent years by state subsidies to encourage private firms to build wind and solar farms and also national electricity grid network investment costs, which previous governments have added to household electricity bills. These network costs have been driven by the need to expa
