AI or software company energy suppliers, tariffs and costs

For AI and software companies, energy considerations are crucial, especially given the industry's reliance on high-performance computing and data processing. These businesses often operate around the clock, demanding a stable and efficient energy supply to maintain productivity and ensure seamless operations. While software development might not seem energy-intensive at first glance, the infrastructure supporting it, such as servers and cooling systems, requires significant power. Understanding the specific energy needs of your business is key to managing costs and ensuring sustainability. Tailoring your energy strategy can also help in meeting corporate social responsibility goals, particularly in reducing carbon footprints and enhancing green credentials.

How much does energy cost for an AI or software company?

There is no published price list for AI and software companies. What an AI or software company pays is set mainly by how much it uses in a year, because suppliers price by consumption band, and then by contract length, meter type, payment method and credit history. The most recent government figures (first quarter of 2026, provisional) put the average unit price paid by UK non-domestic customers at 24.14p per kWh for electricity and 5.17p per kWh for gas, including the Climate Change Levy and excluding VAT. A year earlier the averages were 25.74p and 5.54p. The smallest sites pay the most per unit: businesses using under 20,000 kWh of electricity a year averaged 35.02p per kWh, and those using under 278,000 kWh of gas averaged 7.48p per kWh.

Q1 2026 figures are provisional; next update 29 September 2026. Prices are fully delivered averages including the Climate Change Levy and all other elements except VAT, so standing charges are already spread across the units. Averages across every UK business in a band, not quotes.

Working out a monthly figure for your business

Take the annual kWh from your latest bill or annual statement, find the band above and multiply. A site using 15,000 kWh of electricity a year sits in the very small band: 15,000 × 35.02p is about £5,250 a year, or roughly £440 a month before VAT. A site using 60,000 kWh of gas a year: 60,000 × 7.48p is about £4,490 a year, or roughly £375 a month. Because the smallest band pays a much higher unit rate, an AI or software company that moves into the next band by growing, or that sits near a band boundary, can see its per-unit price change noticeably at renewal.

VAT and the Climate Change Levy on business energy

The prices above exclude VAT. Business energy normally carries VAT at 20% plus the Climate Change Levy (CCL). HMRC applies the 5% reduced rate, with no CCL, in three cases. First, low usage: supplies averaging no more than 33 kWh of electricity a day (1,000 kWh a month) or 145 kWh of gas a day (4,397 kWh a month) are treated as domestic use whoever the customer is. Second, fuel and power for domestic use, which HMRC defines to include homes providing care for the elderly or disabled, children’s homes, hospices and school or university residential accommodation. Third, a charity’s non-business activities. Where a site is mixed, 60% or more qualifying use means the whole supply is charged at 5%; below that the supply is split between the two rates, and the customer gives the supplier a certificate declaring the qualifying percentage.

Is an AI or software company a microbusiness?

Ofgem treats a business as a microbusiness if it has fewer than 10 employees (or their full-time equivalent) and an annual turnover or balance sheet total of no more than £2 million, or if it uses no more than 100,000 kWh of electricity or 293,000 kWh of gas a year. A business can be a microbusiness for one fuel and not the other. Independent AI and software companies that meet either test are covered by Ofgem’s microbusiness rules, which give extra protections around contract terms and renewals (Ofgem: get energy for your business).

Do business energy rates vary by region?

Yes. Part of every unit rate covers the cost of the local electricity distribution network, and Great Britain has 14 licensed distribution areas each with its own charges, so identical contracts are priced differently in, for example, the north of Scotland and London. DESNZ does not publish non-domestic prices by region, so regional figures quoted elsewhere are supplier or broker estimates rather than official statistics.

Which energy supplier is best for AI and software companies?

No supplier specialises in AI and software companies or publishes tariffs specific to them. The cheapest supplier for one business is often not the cheapest for the next, because each prices on the consumption band, meter type, contract length and credit profile in front of it. Compare the total annual cost of like-for-like contract lengths rather than the headline unit rate, and check the standing charge and any out-of-contract rate before signing.

Energy usage profile for AI and software company

AI and software companies typically have a distinct energy usage profile characterized by high electricity consumption, particularly for powering servers, data centers, and cooling systems. These businesses often require uninterrupted power to maintain operations and ensure data integrity. Moreover, with the rise of cloud computing and AI applications, energy needs can fluctuate based on server demand and computational intensity. It's essential for these companies to assess their operational hours and peak usage times to optimize energy consumption effectively. Understanding these patterns enables businesses to negotiate more favourable energy tariffs, potentially reducing overall costs.

What affects bills for AI and software company

Several factors influence energy costs for AI and software companies:

• Operational hours: Extended working hours can lead to increased energy consumption.
• Server and data center usage: High computational needs require more power.
• Cooling requirements: Maintaining optimal temperatures for equipment is energy-intensive.
• Energy efficiency: The efficiency of hardware and infrastructure impacts overall consumption.
• Tariff structures: Choosing the right tariff based on usage patterns can affect costs.
• Location: Regional variations in energy prices can influence bills.

How to compare tariffs

When comparing energy tariffs, AI and software companies should consider the following checklist:

• Analyze historical energy usage to identify patterns.
• Consider flexible tariffs that accommodate peak operational times.
• Evaluate green energy options to align with sustainability goals.
• Check for any hidden fees or contract terms.
• Assess the reliability of the energy provider's service.
• Ensure the tariff supports high consumption needs without penalties.

Gas vs electricity considerations

For AI and software companies, electricity is typically more critical than gas due to the power needs of servers and data centers. However, gas may still play a role in heating office spaces, especially in cooler climates. Given the primary reliance on electricity, companies should focus on securing competitive electricity tariffs that cater to high usage requirements. Additionally, exploring renewable electricity options can enhance sustainability efforts and reduce environmental impact.

Switching process overview

Switching energy providers for an AI and software company involves the following steps:

1. Review current energy usage and contract terms.
2. Research and compare potential energy suppliers and tariffs.
3. Contact the chosen supplier to initiate the switch.
4. Provide necessary business details and current energy consumption data.
5. Ensure a seamless transition by coordinating with both current and new suppliers.
6. Monitor the switch to confirm that billing has commenced correctly.
