Three reasons why UK electricity prices are so high
The government plans to eliminate VAT on domestic electricity, yet UK households continue to face higher energy costs compared to many European nations.

The UK government has announced a reduction of VAT on domestic electricity from 5% to zero, effective this October, as part of efforts to alleviate the cost of living. However, British households still experience some of the highest electricity prices in Europe.
In the second half of last year, medium-use households in the UK ranked fourth for the highest electricity prices when including taxes and levies. Despite government initiatives to lower bills, several factors contribute to the elevated costs.
One significant reason is the reliance on wholesale gas prices, which often dictate electricity pricing. Energy suppliers participate in a bidding process where generating companies propose prices for electricity production. Although renewable energy sources like wind and solar typically offer lower costs, gas generators often set the wholesale price due to their higher operational costs, including fuel purchases and carbon pricing. This situation is exacerbated by geopolitical tensions, such as the conflicts in Iran and Ukraine, which have driven up gas prices.
Another factor is the UK's energy mix. In 2025, approximately 31% of the UK's electricity was generated from natural gas, compared to just 3% in France, where nuclear power accounted for 69% of electricity generation. The US, while having a higher percentage of natural gas in its energy mix at 40%, benefits from lower wholesale gas prices due to its shale gas production.
Additionally, the UK is investing heavily in electricity grid infrastructure, which has contributed to rising domestic electricity bills. The wholesale energy cost component of a typical household bill increased from £311 in 2024-25 to £320 in 2025-26. State subsidies for renewable energy projects and the costs associated with modernising the electricity grid have also added to household expenses. The contribution of network costs to a typical bill rose significantly from £136 in 2019-20 to £250 in 2026.
Energy analysts suggest that the UK has underinvested in infrastructure over the past decade, leading to the current need for substantial spending to catch up. Future projections indicate that network costs may continue to rise, potentially adding another £48 to typical bills by 2030.
The government and some energy groups argue that reducing dependence on volatile international gas prices through the 2030 clean power policy could help lower wholesale electricity costs in the long run. However, the effectiveness of these measures will largely depend on future gas prices, which remain unpredictable. Some analysts advocate for a shift in how policy costs are allocated, suggesting that these should be funded through general taxation rather than being passed on to consumers in their electricity bills.
