Are business energy prices going up?

What actually drives your business energy price

The biggest single driver is the wholesale price of gas. Most of the UK's electricity is still generated from gas, so when gas prices rise, electricity tends to follow. UK wholesale gas is heavily influenced by global liquefied natural gas (LNG) supply, European storage levels and geopolitical events, which is why headlines about conflicts or supply routes can move your renewal quote.

On top of the wholesale cost sit network charges, policy costs such as the Climate Change Levy, supplier operating costs and metering. For business supply there's no price cap, so these costs are priced into the rate agreed on your contract.

Where the market stood in autumn 2026

Through the summer of 2026 the market was volatile, and UK wholesale gas reached some of its highest levels since late 2022 during September, before easing slightly from the peaks. Forward prices for the coming winter have continued to move upward in early October, with wind output dips and tight European gas storage adding pressure.

For businesses, the practical effect is that fixed-rate offers are generally more expensive than they were earlier in the year. That doesn't mean prices will keep rising indefinitely — markets move both ways — but it does explain why quotes feel higher than the rates many firms agreed in the summer.

Why nobody can promise where prices go next

Anyone who claims to know exactly where energy prices will be next year is guessing. Wholesale prices respond to weather, storage levels, global supply events and policy changes, often within days.

What matters more for your business is the shape of the market when you sign: the rate you agree on a fixed contract is locked for the term, whatever happens after. That's why the decision at renewal is less about predicting the future and more about how much certainty your budget needs.

Fixed vs variable when the market is high

When prices are elevated, fixing locks in today's rate — which can feel uncomfortable if prices later fall, but protects you if they climb further. A variable or out-of-contract rate moves with the market in both directions and is typically much higher than a negotiated fixed rate.

For most small and medium businesses, the deciding factor is budget certainty. If a large bill increase would cause real problems, a fixed rate even at a higher unit price is often the safer choice.

What you can actually do about it

You can't control the wholesale market, but you can control how you buy.

• Diary your contract end date and start comparing up to six months before it, while you still have leverage.
• Compare quotes on the same term and the same included charges, so you're seeing genuine differences.
• Check the standing charge as well as the unit rate, especially on low-usage sites.
• Ask whether the price includes network and policy costs or bills them as pass-through.
• Align electricity and gas end dates so you can review both together.

The bottom line

Business energy prices in the UK have been under upward pressure through autumn 2026, but nobody can say with certainty where they'll be in twelve months. The reliable move is to review your options during your switching window, understand exactly what you're signing, and pick a term that matches your plans. A comparison across suppliers is free and puts real numbers against the market's current level.
