Will UK electricity prices go down by 2030?

Most analysts expect UK electricity prices to stay near current levels or rise modestly to 2030, because falling wholesale costs are being offset by rising network and policy charges. A University of Cambridge study found prices could fall by around 45% by 2030 if European renewable targets are met, while business-focused forecasts see costs rising every year to 2030 as non-commodity charges grow. The realistic range for households is roughly 22-30p/kWh.

What will electricity cost in the UK in 2030?

Our base case puts domestic electricity at 24-28p/kWh in 2030, close to the mid-2026 price cap of 24.67p/kWh. The optimistic scenario, where Clean Power 2030 is delivered and gas sets the price far less often, lands at 20-22p/kWh. The pessimistic scenario, with renewed gas shocks and heavy network investment recovery, reaches 30p/kWh or more. Business rates typically run 1-4p above domestic unit rates.

Why are UK electricity prices so high?

Because gas-fired power stations set the wholesale price in most hours, and the UK generates a larger share of its electricity from gas than most of Europe. On top of the wholesale cost, network charges, policy levies and supplier costs now make up around half of a UK electricity bill, and those non-commodity elements are rising as the grid is upgraded.

Should I wait for cheaper electricity before installing solar panels?

Waiting only pays if prices collapse, and no mainstream forecast shows that before 2030. At today's 24.67p/kWh cap a typical 4kW solar system pays back in 10-13 years; even in the optimistic 20-22p scenario payback extends by only 2-3 years, while in the base and high scenarios solar savings grow. Solar acts as a hedge: you fix a large share of your electricity cost at generation cost, whatever the market does.

UK Electricity Price Forecast 2030: Where Bills Are Heading

Anyone modelling a solar payback, a heat pump, or a business energy budget runs into the same question: what will UK electricity actually cost in 2030? Nobody can answer it precisely, but the forces pulling the price in each direction are well documented, and the credible forecasts cluster tightly enough to plan around. This guide sets out where prices are now, what pushes them up and down between here and 2030, and three costed scenarios you can use in your own maths.

Where UK Electricity Prices Are in 2026

The Ofgem price cap for April to June 2026 put the average GB unit rate at 24.67p/kWh including VAT for direct debit customers, with a standing charge on top. Businesses are not capped: typical commercial unit rates run 25-30p/kWh depending on contract timing and consumption profile. Both figures remain far above the roughly 14-16p/kWh households paid before the 2021-22 gas crisis, and the House of Commons Library's ongoing price briefing shows the cap still moving in steps rather than trending back to pre-crisis levels.

The reason prices stay high is structural. Gas-fired stations set the wholesale electricity price in the majority of hours in the GB market, so UK electricity tracks international gas even as renewables grow. And the non-wholesale half of the bill, network charges, policy levies and supplier costs, has been rising steadily.

What Pushes Prices Up Between Now and 2030

Network investment. The grid build-out needed for electrification, new transmission lines, substations and connections, is recovered through network charges on bills. This is the largest single upward pressure on the non-commodity side of the bill through the late 2020s.
Non-commodity charges on business bills. npower Business Solutions forecasts business electricity costs rising every year to 2030, topping £250/MWh (25p/kWh), driven primarily by these charges rather than wholesale prices.
Gas exposure. Until gas stops setting the marginal price in most hours, any repeat of a gas supply shock feeds straight into electricity bills. The Financial Times has reported analysis suggesting UK electricity could cost more in 2030 than it did in the aftermath of the invasion of Ukraine.

What Pulls Prices Down

Renewables displacing gas. The government's Clean Power 2030 plan targets a decarbonised power system by 2030. Every hour in which wind and solar meet demand is an hour gas does not set the price. A University of Cambridge study found that if 2030 renewable targets are met across Europe, UK and Irish electricity prices could fall by around 45% by 2030, the largest predicted drop in Europe precisely because current prices are so gas-exposed.
Market reform. The Review of Electricity Market Arrangements (REMA) is reshaping how the wholesale market prices power, with the government pursuing a reformed national pricing model. The aim is to weaken the link between cheap renewable generation and the gas-set marginal price.
Cheaper generation. The government's own generation cost projections have wind and solar as the cheapest new capacity on the system, well below gas-fired generation.

UK Electricity Price Forecast 2030: Three Scenarios

Put those forces together and the credible outcomes cluster into three bands. These are our scenarios, built on the sources above; treat them as planning ranges, not predictions.

Scenario	Domestic (p/kWh)	Business (p/kWh)	What has to happen
Base case	24-28p	25-31p	Wholesale drifts down as renewables grow, but network and policy charges absorb most of the gain. Prices hold near today's level in real terms.
Optimistic	20-22p	22-25p	Clean Power 2030 delivered on time, REMA reform weakens the gas link, no new gas shocks. The Cambridge scenario starts to materialise.
Pessimistic	30p+	32p+	Renewed gas price shocks, grid build-out delays, and full network cost recovery land on bills together.

Note what is absent: no mainstream forecast has UK electricity returning to the pre-crisis 14-16p/kWh world by 2030. Even the optimistic case leaves prices a third above where they were in 2020.

What This Means for Solar Payback

Solar economics are a direct function of the electricity price you avoid paying. At the current 24.67p/kWh cap, a typical 4kW system costing £6,600-£8,500 pays back in 10-13 years, see our full solar panel cost guide and what bills look like with solar.

Base case (24-28p): payback holds at 10-13 years or improves slightly. The maths you run today stays valid.
Optimistic (20-22p): payback stretches by roughly 2-3 years, but your bill also falls, and export income through the Smart Export Guarantee still contributes.
Pessimistic (30p+): payback shortens towards 8-10 years, and every kWh you self-consume is worth more.

That asymmetry is the practical takeaway: solar is a hedge. Once the system is on the roof, the cost of the electricity it generates is fixed for 25+ years, whatever the wholesale market and network charges do. Businesses feel this even more strongly, at commercial rates of 25-30p/kWh a commercial rooftop system typically pays back in 3-5 years, well inside even the most optimistic window for market-wide price relief.

Bottom Line

Plan around 24-28p/kWh for households and 25-31p/kWh for businesses in 2030, hope for the Cambridge scenario, and stress-test against 30p+. If the deciding factor for a solar or battery investment is "electricity will be cheap again soon", the forecasts do not support waiting; if it is protection against the pessimistic case, they support acting.
