Will energy prices go up in 2026?
UK energy prices are expected to remain volatile through 2026-2030. The Ofgem price cap currently sits at approximately £1,568-£1,738 per year for a typical household, significantly above pre-2021 levels of £1,042. Most analysts forecast prices will stay elevated, with a long-term trend of approximately 5% annual increases driven by infrastructure costs, carbon pricing, and global gas market dependencies.
Key Points:
- Current price cap: £1,568-£1,738/year (vs £1,042 in 2021)
- Electricity unit rate: ~24.5p/kWh (vs ~17p in 2021)
- Long-term trend: ~5% annual increase expected
- Wholesale gas prices remain the primary driver
- Renewable energy provides a hedge against future rises

What Drives Energy Prices
Wholesale Gas Prices
The UK generates ~40% of electricity from gas. Global gas prices directly affect UK bills. This dependency is expected to slowly decline as renewable capacity increases.
Carbon Pricing
The UK Emissions Trading Scheme adds cost to fossil fuel generation. Carbon prices are expected to increase as net zero targets approach, pushing electricity prices higher.
Grid Infrastructure
Billions of pounds of investment in grid upgrades, offshore wind connections, and interconnectors will be recovered through bills over the coming decades.
Ofgem Price Cap
Reviewed quarterly, the cap adjusts to reflect wholesale costs. While it protects consumers from sudden spikes, it cannot prevent sustained increases.
What This Means for Scottish Homeowners
The Case for Renewable Energy
Once installed, solar generation is free. At current rates of 24.5p/kWh, every unit generated saves you money.
If prices rise 5% annually, a system installed today pays back faster each year as the value of self-consumed energy increases.
Greater spreads between off-peak and peak rates mean more profit from battery storage strategies.
Switching from gas to an electric heat pump removes dependence on volatile gas markets.
With solar, battery, and a heat pump, households can generate 60-70% of their energy needs, insulating against future price shocks.
