If you run a business in the UK, energy prices are probably never far from your mind. After years of elevated costs following the 2022 energy crisis, many business owners were hoping for relief in 2026. Instead, a new geopolitical storm has hit — and the ripple effects are being felt on every energy bill across the country.

Here's everything you need to know about where UK business energy prices stand right now, what the US–Iran conflict has done to global markets, and what a fragile ceasefire really means for your bottom line.

## Where UK Business Energy Prices Stand in 2026

Even before the Iran conflict erupted, UK businesses were already paying far more for energy than a few years ago. Following a 90% surge in electricity costs between 2021 and 2024, commercial electricity rates remain approximately 75% higher than pre-2021 levels — a significant and sustained burden on cash flow and growth.

As of early 2026:

- **Small businesses** are paying around **27.8p per kWh** for electricity, with a standing charge of approximately 45.6p per day — translating to roughly **£238 per month** for a typical SME.
- **Larger businesses** are paying around **26.2p per kWh**, costing an average of **£862 per month**.
- A "good rate" for business electricity in 2026 is considered to be between **20p and 23p per kWh** — but many businesses are locked into contracts above this.

On top of the unit rate, businesses face:

- **VAT at 20%** (some qualifying non-profits pay 5%)
- **Climate Change Levy (CCL)** at 0.801p per kWh from April 2026
- **TNUoS charges**, which were forecast to nearly double for many users from April 2026, and are expected to rise by over 10% per year until the end of the decade
- A new **Regulated Asset Base (RAB) charge** of 0.346p/kWh to fund new nuclear power stations

Non-commodity costs — the network charges, levies, and government-imposed fees that sit on top of the wholesale price — now make up nearly **60% of a typical business electricity bill**, according to Cornwall Insight. That means even when wholesale gas prices fall, business energy bills don't fall proportionally.

## The Iran War: How It Shook Global Energy Markets

On 28 February 2026, Israel and the United States launched military strikes against Iran. Iran retaliated — and critically, closed the Strait of Hormuz, the narrow sea lane through which approximately **20% of the world's oil supply** passes.

The International Energy Agency described this as the **"largest supply disruption in the history of the global oil market."** The consequences were immediate and severe:

- **Brent crude surged** from around $72–$73 per barrel before the war to a peak of nearly **$120 per barrel**
- **UK wholesale natural gas prices rose by roughly 75%** between late February and 23 March 2026
- UK NBP (National Balancing Point) gas prices spiked to **175p per therm** at their worst
- **Qatar's Ras Laffan** LNG complex — which accounts for around 20% of global LNG supply — was "extensively damaged," with analysts estimating **17% of its LNG capacity offline for three to five years**
- European gas storage, which should ideally be at 80% by summer, entered the refill season at just **28% full** — the lowest level since the 2022 energy crisis

For UK businesses, this fed through rapidly into pump prices and energy contract quotes. Petrol prices rose by **14p per litre** in the first month of the conflict, while diesel climbed by **29p per litre**. The Bank of England revised UK inflation forecasts upward, projecting CPI of between **3% and 3.5%** for Q2 and Q3 of 2026, and the interest rate cuts many businesses had been counting on appear increasingly unlikely — with rate hikes now back on the table.

## The Ceasefire: Relief or False Dawn?

On 8 April 2026, President Trump announced a **two-week ceasefire** between the US and Iran, contingent on Iran immediately reopening the Strait of Hormuz. Markets responded with a surge of optimism:

- Brent crude fell **13%**, settling at around **$94.80 per barrel**
- WTI crude dropped more than **15%** to $95.75
- European gas (TTF) fell by **16.66%**, dropping below €45/MWh

But here's the critical point for UK businesses: **these prices still remain well above pre-war levels**, and energy experts are warning that a return to normality is nowhere near as simple as a signed truce.

### Why the Ceasefire Isn't a Full Fix

**1. Infrastructure damage is permanent in the near term.** The Ras Laffan complex in Qatar — a major LNG supplier to the UK and Europe — has sustained severe physical damage. Analysts now expect the timeline to restore full capacity to extend to "months, if not years," far beyond the earlier estimate of four to six weeks.

**2. The Strait of Hormuz is still not fully open.** Iran allowed 10 tankers through during ceasefire negotiations — the first traffic in a month — but mines remain in the water and shipping is still constrained. Full commercial operations require mine-clearing, which alone takes months, plus new risk assessments for carriers.

**3. Shipping costs remain elevated.** The Baltic Dirty Tanker Index hit a record **3,737** at the height of the conflict, compared to around 1,000 for most of 2025. War-risk insurance premiums remain high, adding to the delivered cost of crude.

**4. European storage faces a crisis-level challenge.** With the continent entering summer at just 28% storage capacity, strong injections are needed urgently. But supply remains constrained from multiple directions: Ras Laffan damage, Hormuz restrictions, and Norwegian maintenance outages all limit what can be injected.

**5. The ceasefire is temporary and fragile.** Iran's Supreme National Security Council has threatened a "severe response" in the event of any violations, and peace talks in Islamabad involve deeply divergent negotiating positions — Iran's nuclear programme, sanctions relief, and US force withdrawal among them. Even optimists acknowledge the gap between the two sides remains significant.

The EU's Energy Commissioner summarised it bluntly: even if peace were achieved tomorrow, "we will not go back to normal in the foreseeable future."

## What This Means for UK Business Energy Bills Right Now

The picture is mixed, and it depends heavily on your contract situation:

**If you're on a fixed-rate contract**, you're currently shielded from the worst of the volatility — but your renewal quote, when it comes, will almost certainly be higher than your current rate. The forward curve for Summer 2026 delivery has shifted dramatically upward.

**If you're out of contract**, you are being exposed to elevated spot prices at one of the most volatile moments the market has seen in years. Getting onto a fixed deal quickly — even at elevated rates — provides certainty in an uncertain environment.

**If your contract renews in summer or autumn 2026**, watch the market closely. Prices have come off their peak following the ceasefire announcement, but structural supply damage means elevated prices are likely to persist. Locking in now could protect against further spikes if the ceasefire collapses.

**For all businesses**, the Iran conflict has reinforced a brutal truth about the UK energy market: non-commodity charges are rising regardless of geopolitics, TNUoS charges are increasing year on year, and the end of the Energy Bill Relief Scheme in 2023 means there is no government safety net for commercial customers.

## What Can UK Businesses Do?

Given all of the above, here are the most effective steps you can take:

**1. Compare your contract now.** Don't wait for your renewal date. The market is volatile, and prices can spike further if the ceasefire breaks down. Use a broker or comparison service to see whether current market rates beat your renewal quote.

**2. Consider a fixed-rate deal for certainty.** While flexible or basket contracts can sometimes deliver savings, the current environment rewards predictability. A fixed contract removes your exposure to further spikes.

**3. Explore renewable energy options.** Wind, solar, and biomass generation remove reliance on the gas-driven wholesale market altogether. On 25 March 2026, UK wind generation hit a record **23,880 MW in a single day**, demonstrating the scale renewables can now deliver. A 100% renewable tariff also provides greater insulation from fossil fuel price shocks.

**4. Check eligibility for exemptions.** Some businesses in energy-intensive sectors may qualify for Network Charging Compensation (NCC) or Energy Intensive Industry (EII) exemptions from some non-commodity charges. These can meaningfully reduce bills.

**5. Reduce consumption.** The most reliable hedge against any price environment is using less energy. Smart meters, LED lighting, better HVAC controls, and shift-based energy management can all cut consumption without cutting output.

## The Bigger Picture: Energy Security Is Now a Business Issue

The Iran conflict has exposed something UK business owners have long suspected: the UK's commercial energy market is deeply exposed to geopolitical events thousands of miles away. As an island nation that has wound down its own North Sea production and relies heavily on imported LNG — much of it from Qatar — any disruption to Middle Eastern supply routes hits UK wholesale prices fast and hard.

Calls have grown louder in recent weeks for the UK government to reconsider its North Sea licensing policy and expand domestic energy production. Whether or not that happens, the Iran crisis has given urgency to the case for energy independence — both at a national level and a business level.

For now, the ceasefire offers a moment of relative calm. But with talks fragile, infrastructure damaged for years, and Europe scrambling to rebuild gas storage, UK businesses should treat this as a window of opportunity — not a signal that the storm has passed.

## Key Takeaways

- UK business electricity rates in 2026 sit around 26–28p per kWh, roughly 75% above pre-2021 levels
- The Iran conflict triggered the largest global oil supply disruption in history, pushing UK wholesale gas prices up ~75% in a month
- The US–Iran ceasefire (8 April 2026) brought prices back from their peak, but Brent crude remains well above $90 — far higher than the pre-war $72
- Physical infrastructure damage at Ras Laffan means LNG supply shortfalls will persist for years, regardless of diplomacy
- The ceasefire is fragile and temporary — further volatility remains a serious risk
- Businesses should lock in fixed contracts, explore renewables, and review their energy strategy now while prices have eased from their worst
