Energy Bills Set for Biggest Jump in Four Years—Here's What to Do
UK heating costs are rising sharply this autumn. We break down your options and show you how to cut your bill before winter hits.
Autumn 2026 brings unwelcome news for UK households. Energy bills are forecast to rise by their largest margin in four years, putting pressure on budgets already stretched by inflation. With winter approaching, now is the moment to act—not panic, but plan.
What's driving the increases?
The Ofgem price cap remains your benchmark for mains gas at 6.04p/kWh and electricity at 24.5p/kWh. These rates are set to move higher, reflecting global energy markets and supply chain pressures. Households relying on heating oil face a particularly tough outlook, with current wholesale prices at 99.5p/litre—a level that compounds over a winter's worth of deliveries.
The silver lining? Renewable energy is advancing. New offshore wind capacity coming online, including projects like the Montrose plant, is expected to add generation capacity and ease wholesale prices in the medium term. That won't help you this winter, but it signals the grid is transitioning.
Your heating fuel options ranked by current cost
If you're able to switch fuels, here's the real-world comparison:
- Wood pellets: 7.2p/kWh — cheapest option if you have a suitable stove or boiler
- Mains gas: 6.04p/kWh — stable, regulated, and widely available (though rising)
- Electricity: 24.5p/kWh — most expensive, but essential for those without gas
- Heating oil: 99.5p/litre — volatile, expensive, and tied to global crude prices
Wood pellets remain the standout value, but require upfront investment in a compatible heating system.
What you should do right now
1. Lock in a better rate
If you're on a variable tariff, investigate fixed-rate deals before prices climb further. Compare your options across mains gas, electricity, and heating oil suppliers.
2. Check your boiler efficiency
A poorly serviced boiler wastes money. Get a professional check-up before winter demand peaks.
3. Insulate, insulate, insulate
Loft and cavity wall insulation reduce heat loss by up to 30%. This is the single most cost-effective investment you can make.
4. Consider alternative fuels
If you heat with oil, explore whether wood pellets or a heat pump might work for your property. New renewable heating grants are still available in some regions.
5. Monitor supplier reviews
As bills rise, customer service quality matters. Read independent reviews before switching.
The bottom line
You can't control global energy markets, but you can control your response. Don't wait until November to act. The households that keep bills manageable this winter are those making decisions in September and October—that's now.
