The UK’s electricity prices remain closely linked to gas costs, even as renewable energy grows, with the government now moving to reform how power is priced amid rising household bills. The issue has come under renewed focus following a surge in global gas prices, which has pushed up electricity costs across Britain despite increased reliance on wind and solar energy.
Why Gas Continues to Set Electricity Prices
The UK relies heavily on gas across its energy system, with around a third of total energy consumption tied to it, and gas-fired power stations generating a significant share of electricity. Under the current pricing system, known as marginal pricing, the cost of electricity is determined by the most expensive source needed to meet demand, which is often gas. This means that even when cheaper renewable energy is available, gas prices still dictate overall electricity costs, keeping bills high. As reported by The Guardian, gas set the electricity price in the UK for the vast majority of the time in recent years, highlighting the system’s dependence on fossil fuels.
Why Renewables Are Not Lowering Bills Yet
Although renewable energy sources like wind and solar are cheaper to produce, they do not directly reduce market prices under the current system. Energy providers prioritise lower-cost sources first, but when demand rises, gas-powered generation is used — and its higher cost becomes the benchmark for pricing. Experts note that while renewable capacity is increasing, it may take several years before it significantly reduces overall electricity prices.
The Government Plans to Weaken the Gas Link
The UK government has announced plans to reduce the influence of gas on electricity pricing by encouraging older renewable energy projects to move to fixed-price contracts. This shift would help stabilise costs by breaking the direct link between volatile gas markets and electricity prices. Generators that do not adopt the new system could face higher windfall taxes, as part of efforts to ensure more predictable pricing and reduce excess profits.
What It Means for Household Bills
Despite the proposed reforms, energy bills are expected to remain high in the short term, with forecasts suggesting continued pressure on household costs. The transition to a new pricing model is likely to take time, and immediate relief for consumers remains uncertain. In the longer term, the government hopes that expanding renewable energy and reducing reliance on gas will lead to more stable and potentially lower electricity prices.
Shift Towards Long-Term Energy Changes
Alongside pricing reforms, efforts are being made to encourage households to adopt low-carbon technologies such as solar panels and electric vehicle charging systems. These measures are aimed at reducing dependence on fossil fuels and giving consumers more control over their energy use. While reforms are underway, the UK’s electricity pricing system continues to reflect its reliance on gas — a factor that remains central to both current costs and future policy changes.
