How energy market conditions shape SME growth and investment plans

As UK energy prices remain relatively high, small and medium-sized businesses (SMEs) are feeling the strain on budgets, investment plans, and overall growth potential. Understanding how the UK energy market affects your business is crucial to building resilience and planning. 

This guide explores current market conditions, why prices remain volatile and practical ways SMEs can cut costs, improve efficiency and secure better energy deals to stay competitive in today’s challenging environment.

Five-point summary of our energy market conditions and SME growth guide

1. UK energy prices remain volatile, with electricity costs up to 92% higher than the EU average for medium-sized businesses.
2. Household energy debt has reached record levels, indirectly impacting SME revenues as consumer spending falls.
3. Global factors like the war in Ukraine and supply disruptions have kept wholesale energy prices elevated across the UK energy market, despite recent stabilisation.
4. SMEs are shifting focus from growth to survival, prioritising cost control and cash flow management amid rising energy expenses.
5. Investment in energy efficiency and sustainability - including smart meters, LED lighting, and on-site renewables - is helping forward-looking UK businesses cut costs long-term.

What does the current energy market landscape look like?

In a recent state of the market report, Ofgem outlined the following key trends in the UK energy market. 

Electricity prices in the UK continue to rank among the highest in Europe. They are about 44% higher than the European Union (EU) average for households and a striking 92% higher for medium-sized businesses. But gas prices are closer to the European median.

And energy debt has continued to rise, reaching a record high of £4.48 billion in late 2025 with around 3.6 million customers in arrears. 

While this data centres on household energy debt, it has knock-on effects within the business energy market because when households struggle to pay their bills, they spend less money in shops, restaurants and on other services. 

Despite the UK energy market's challenging outlook, there are also some positive changes.

Service quality is reported to have improved despite the high prices, with fewer companies making complaints and contacting suppliers becoming easier. The market includes 22 domestic suppliers and 94 business suppliers, although 6 large firms still control 92% of the market share. Octopus has been the only major supplier increasing its share and has expanded to more than 200,000 customers within a year.

The transition to smarter energy use is ongoing. Suppliers installed 650,000 household and 26,000 business smart meters during a single quarter in 2025. Smart tariffs are still at an early stage but growing, with time-of-use tariffs rising quickly and electric vehicle tariffs expanding fast. The Market-wide Half-Hourly Settlement (MHHS) rollout is expected to increase the number of flexible tariffs in the market throughout 2026.

Why have energy prices been rising?

A combination of global and local pressures has caused energy prices to rise, not just one single cause. 

Wholesale energy prices increased by more than 500% between August 2021 and August 2022. The market was heavily affected when Russia invaded Ukraine and gas supplies were disrupted, with key infrastructure such as Nord Stream 1 being shut down. In response, European countries reduced their dependence on Russian gas and filled storage facilities with liquified natural gas from across the globe.

During 2025, prices stabilised, and business gas prices even fell slightly as we entered 2026. This suggests the market has calmed after the extreme changes of recent years. But prices are still high, and political tensions around the world, particularly in the Middle East, could make them unstable again. Experts at Cornwall Insight believe prices may not return to pre-pandemic levels for the rest of this decade.

What impacts the cost of business energy?

The cost of business energy is influenced by several internal and external factors, such as:

• Season - energy use typically rises in winter for heating and in summer for cooling, which increases demand and often raises prices.
• Location - network and distribution charges vary by region, so businesses in different areas can pay different rates for the same energy.
• Supply and demand - wholesale energy prices change depending on how much energy is available and how much is being used nationally.
• Renewable energy transition - investment in cleaner generation and grid upgrades can affect costs as the energy system modernises.
• Lighting - inefficient or constantly used lighting significantly increases electricity consumption and operating costs.
• Heating - poor insulation or outdated heating systems require more energy to maintain comfortable temperatures.
• Office equipment - computers, printers, kitchen appliances and other equipment all add to daily electricity usage, especially if left on unnecessarily.
• Peak time demand - using energy during high-demand periods is usually more expensive than operating during off-peak hours.

How long will the energy crisis last?

A common question for SMEs is how long will the energy crisis last? 

While the acute phase of the energy crisis has eased, instability is likely to continue. Energy prices fell in early 2025 after a period of relative stability and slight increases. Even so, energy is still much more expensive than before, and gas prices are around double what they were in early 2021. Electricity prices are about a third higher. 

Current forecasts suggest that prices could fall again during 2026, but instability in the Middle East could affect this.

How will energy costs affect SMEs?

For small and medium-sized businesses, rising energy costs influence whether a business can grow, invest or sometimes continue operating. Here’s a list of some of the ways energy costs can affect SMEs:

Growing concern over energy prices

Many small businesses have reported energy bill increases that have cut profit margins, reduced hiring plans and in some cases, forced shorter opening hours or temporary closure. While larger organisations can often negotiate lower energy rates, smaller firms have much less bargaining power. This can mean SMEs are more exposed to sudden price increases that they cannot control.

Planning and budgeting challenges

Unpredictable prices make financial planning difficult. When energy costs can change quickly, businesses struggle to forecast spending, set stable prices or confidently commit to long-term investments.

No business energy bill support

Government support schemes have played an important role in helping businesses manage their business energy bills. But, unlike with domestic energy, there is no price cap on business energy. Many SMEs are postponing strategic decisions, including expansions, new hires or even basic maintenance, as they wait to see if they will receive relief. This level of dependency is particularly worrying because it shows that SMEs are increasingly being placed in a reactive position.

Surviving rather than scaling

For many SMEs, the focus has shifted from growth to simply trying to stay afloat, with businesses aiming to stay strong and adaptable in an unpredictable environment. Instead of prioritising expansion, hiring or entering new markets, companies are concentrating on strengthening cash flow, reducing costs and protecting themselves against future uncertainty.

Investment in energy efficiency and sustainability

While rising costs create pressure, they are also pushing businesses to rethink how they use energy. Many SMEs are investing in energy-efficient lighting, heating systems, smart meters and other technology to reduce long-term energy costs. Although these upgrades require upfront spending, they can lower operating costs over time and make businesses less exposed to future price spikes. 

How to offset rising energy costs

While SMEs cannot control wholesale markets, they can control how they respond.

Energy efficiency

Improving energy efficiency is one of the simplest ways to reduce bills. Upgrading lighting to LEDs, improving insulation and maintaining HVAC systems can significantly cut consumption. Replacing old equipment with modern, lower-energy models also helps. Small operational changes, like turning off equipment when not in use, add up to meaningful savings over time.

Energy audit

A business energy audit can identify where power is being wasted. By analysing usage patterns, equipment performance and building efficiency, businesses can prioritise the most effective improvements. Audits often reveal low-cost fixes such as smart heating controls like timers or temperature adjustments, as well as longer-term upgrades that deliver measurable financial savings.

Staff training

Training staff to turn off equipment properly, manage heating and cooling settings and recognise waste can help reduce consumption. When teams understand the cost impact of energy, efficiency becomes part of everyday operations.

Renewable energy generation

Many UK businesses are now exploring on-site energy generation as part of their long-term energy strategy, with solar power being the most popular option. While renewable energy systems require upfront investment, they deliver multiple benefits, including reduced grid reliance, lower energy bills, improved energy resilience and enhanced environmental credentials.
