Current Situation: UK Industrial Electricity Prices in 2026
2026 Industrial Electricity Price Context
UK industrial electricity prices in April 2026 stand at approximately 28–32p/kWh for medium and large manufacturing sites on fixed-term contracts. This remains significantly elevated compared to pre-energy-crisis levels of 10–15p/kWh in 2019–2020. While prices have eased from the extreme peak of 2022 (when spot prices briefly exceeded 100p/kWh), they have stabilised at a level approximately 2–2.5x the pre-crisis norm.
The elevated price environment has lasted longer than most industry analysts initially forecast. Several structural factors — described below — suggest that a full return to pre-2021 pricing is unlikely in the 2026–2030 planning horizon relevant to most factory capital investment decisions.
For factory owners, this means that the electricity cost assumptions used for solar financial modelling are well-established. Unlike the uncertainty of 2022–2023, when price forecasts varied wildly, the current market provides a more stable base for investment decisions.

Key Drivers of Future UK Electricity Prices
Understanding what drives UK electricity prices helps assess which scenarios are most likely. Five structural factors will shape prices through to 2030.
1. Gas Dependency and Wholesale Gas Prices
Gas-fired power stations remain the UK's "swing" electricity generation source, setting the marginal price of electricity on most days. When gas is expensive, electricity is expensive. The UK's gas dependency has reduced as more renewables come online, but gas still set the marginal price in 2024 approximately 40–50% of the time. Any sustained gas price increase — driven by supply disruption, LNG competition, or geopolitical events — will feed through to electricity prices within weeks.
2. Renewable Capacity Build-Out
The UK government's target of 50GW offshore wind by 2030 (up from ~14GW currently) should, if achieved, substantially reduce the frequency with which gas sets the marginal electricity price. More zero-marginal-cost renewable generation pushes wholesale prices down. However, build-out delays, grid connection queues, and planning bottlenecks may mean targets are missed, limiting this downward price pressure.
3. Network Costs: TNUoS and DUoS
Transmission network use of system (TNUoS) charges and distribution use of system (DUoS) charges are structural components of the electricity bill that have been rising steadily and are expected to continue rising. These charges fund the upgrade of the electricity grid to accommodate renewable generation and increasing electrification of heating and transport. They are largely independent of wholesale gas prices and will not fall even if gas prices decline.
4. UK Emissions Trading Scheme (UK ETS)
The UK ETS carbon price applies to electricity generators, adding a carbon cost to fossil-fuel generation that feeds through to electricity prices. The UK ETS price was approximately £35–45/tonne CO2 in 2026. As the cap on emissions is tightened in line with the UK's Net Zero trajectory, the ETS price is expected to rise, adding further upward pressure on electricity prices — particularly if gas remains in the generation mix.
5. Electricity Market Reform
The UK government's Review of Electricity Market Arrangements (REMA) is exploring fundamental reforms to how electricity is priced, including potential zonal pricing (different prices in different regions of the UK). Reform could theoretically improve the pass-through of low-cost renewable energy to consumers, but the outcome and timeline remain uncertain. Factories in Scotland or North England could benefit from lower zonal prices if reform proceeds.
Three Scenarios for UK Electricity Prices 2026–2030
Rather than relying on a single forecast, factory owners should plan using a range of scenarios. Here are three plausible paths for UK industrial electricity prices to 2030.
Optimistic Scenario
Offshore wind and interconnectors deliver on schedule; demand falls as efficiency improves; LNG supply remains ample
Probability: 25%
Base Case Scenario
Renewable build delayed but progressing; gas remains in mix; network costs rise gradually; modest ETS price increases
Probability: 50%
Pessimistic Scenario
Gas supply disruption returns; wind build significantly delayed; grid constraint costs rise steeply; ETS price spikes
Probability: 25%
What This Means for Solar ROI Under Each Scenario
The following table shows how the financial return on a typical 300kW factory solar system (£220,000 installed) varies under each electricity price scenario over 10 years.
| Scenario | Avg Price 2026–2030 | Year 1 Saving | Simple Payback | 10-Year Net Return |
|---|---|---|---|---|
| Optimistic (prices fall) | ~26p/kWh | £70,200 | 3.7 years | +£482,000 |
| Base case (stable) | ~29p/kWh | £78,300 | 3.3 years | +£563,000 |
| Pessimistic (prices rise) | ~35p/kWh | £85,500 | 2.8 years | +£698,000 |
Key Insight
Factory solar is financially attractive under all three scenarios. In the optimistic scenario (prices fall), payback is 3.7 years — still excellent. In the pessimistic scenario (prices rise further), payback is just 2.8 years. The investment is robust to price uncertainty: higher prices improve the return, lower prices merely moderate it. There is no realistic electricity price scenario in which a well-designed factory solar system is a poor investment.
Why Solar Insulates You From Price Uncertainty
The key characteristic that makes solar particularly valuable in an uncertain price environment is that it converts a variable cost into a fixed cost.
Your grid electricity price fluctuates with each contract renewal — sometimes significantly. Solar generation, by contrast, costs the same amount each year once installed (essentially zero, once the capital is deployed). The "cost" of each solar kWh is simply the annual capital repayment or the amortised capital cost, which is fixed and known at the time of investment.
This means that if electricity prices spike again — as they did in 2022 — your solar-generated electricity is not affected. You continue generating at your fixed cost whilst your unhedged competitors pay dramatically more for grid power. The 2022 energy crisis gave factory owners a visceral lesson in this risk, and many of the factories installing solar in 2024–2026 cite energy price volatility as a primary driver of the decision.
SEG Income Projections 2026–2030
The Smart Export Guarantee (SEG) obliges licensed electricity suppliers with over 150,000 domestic customers to offer export tariffs to small-scale generators. For factory systems, most exported electricity will be valued under SEG or a commercial Power Purchase Agreement (PPA) arrangement.
Current SEG rates from major suppliers for commercial solar in 2026 range from 3p/kWh to 6p/kWh, depending on the supplier, contract duration and system size. SEG rates for commercial sites above 50kW typically require individual negotiation rather than the published tariffs available to domestic generators.
| Scenario | SEG Rate 2026 | SEG Rate 2030 | Annual Export Income (300kW, 20% export) |
|---|---|---|---|
| Optimistic | 5p/kWh | 4p/kWh (stable or slight fall) | £2,850/yr |
| Base case | 5p/kWh | 5–6p/kWh (gradual increase) | £2,850/yr |
| Pessimistic | 5p/kWh | 8–10p/kWh (follows wholesale prices) | £2,850–£5,700/yr |
SEG export income is a relatively minor component of the solar financial case for factories (typically 3–5% of total annual benefit). The vast majority of financial return comes from avoided grid electricity cost, not export income. This is why maximising self-consumption — through good system sizing and potentially battery storage — is more financially important than maximising export.
Practical Planning Recommendations for Factory Owners
Based on the price analysis above, here is what factory owners should consider in their energy planning for 2026–2030.
Lock In Solar Costs Now — Do Not Wait for Price Stability
Current prices make factory solar highly attractive. Every month of delay means another month of full-price grid electricity — at 29p/kWh, a factory consuming 500,000 kWh/year and hoping for a 40% offset is spending an additional £4,800 per month on electricity it could be generating itself.
Model Your Solar ROI at Base Case and Pessimistic Scenarios
Request that your solar installer provides financial projections under at least two price scenarios — base case (stable at ~29p/kWh) and pessimistic (rising to ~35p/kWh). If the investment looks compelling under both, you have a robust decision. Only if it only works under the pessimistic scenario should you be cautious.
Consider a Power Purchase Agreement (PPA) as an Alternative
If capital expenditure is constrained, a solar PPA allows you to benefit from solar generation without the upfront cost. A third party funds, owns and maintains the solar system; you pay a fixed pence-per-kWh rate (typically 10–18p/kWh) for the electricity generated — still well below current grid rates, and with price certainty for the contract term (typically 10–20 years).
Factor in Electricity Price Risk in Your Capital Appraisal
When calculating the NPV of a solar investment, use a sensitivity analysis that includes electricity price as a variable. A project that delivers positive NPV under base case and pessimistic scenarios — with particularly strong returns under pessimistic — is genuinely well-hedged. This analysis satisfies most finance director and board-level scrutiny of capital investment decisions.
