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 depends on how much it uses in a year, when it agreed its contract and for how long, wholesale prices at that time, the standing charge, meter type, payment method and credit history. The most recent government figures, for the second quarter of 2026 (April to June, provisional), put the average price paid by UK non-domestic customers at 24.51p per kWh for electricity and 5.28p per kWh for gas, including the Climate Change Levy and standing charges and excluding VAT. A year earlier the averages were 24.03p and 5.31p. Smaller users typically pay more per unit: businesses using under 20,000 kWh of electricity a year averaged 38.36p per kWh, and those using under 278,000 kWh of gas averaged 9.31p per kWh.

Q2 2026 figures are provisional; next update 17 December 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, and not comparable with a supplier’s unit rate.

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 for a rough benchmark. A site using 15,000 kWh of electricity a year sits in the very small band: 15,000 × 38.36p is about £5,750 a year, or roughly £480 a month before VAT. A site using 60,000 kWh of gas a year: 60,000 × 9.31p is about £5,590 a year, or roughly £465 a month. The bands are statistical groupings used by the government, not supplier price breaks, so treat them as a guide to what similar-sized sites paid rather than a price you will be offered. To judge an actual quote, compare its total annual cost (unit rate × your annual kWh, plus the daily standing charge × 365) with what you pay now.

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. From 1 October 2026 to 31 March 2027, electricity that qualifies for the reduced rate is charged at 0% VAT instead of 5% in England, Scotland and Wales; qualifying gas stays at 5%, qualifying electricity in Northern Ireland stays at 5%, and electricity returns to 5% from 1 April 2027. HMRC has not changed which supplies qualify or the certificate process; the same rules decide whether a supply gets 0% or 20%. Where a site is mixed, 60% or more qualifying use means the whole supply gets the reduced rate; below that the supply is split between the two rates, and the customer gives the supplier a certificate declaring the qualifying percentage.

Do Ofgem’s microbusiness protections apply to AI and software companies?

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?

There is no single answer. Suppliers price business contracts individually rather than publishing standard tariffs for AI and software companies, so the cheapest supplier for one business is often not the cheapest for the next: each prices on the consumption, 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 what happens when the contract ends before signing.

How AI and software companies use energy

AI and software companies typically have a distinct energy usage profile characterised by high electricity consumption, particularly for powering servers, data centres, 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 optimise energy consumption effectively. Understanding these patterns enables businesses to negotiate more favourable energy tariffs, potentially reducing overall costs.

What affects energy bills for AI and software companies

Several factors influence energy costs for AI and software companies:

• Operational hours: Extended working hours can lead to increased energy consumption.
• Server and data centre 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:

• Analyse 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 or electricity: what matters most

For AI and software companies, electricity is typically more critical than gas due to the power needs of servers and data centres. 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.

How switching works

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.
