Dairy farm energy suppliers, tariffs and costs

For dairy farm businesses, managing energy effectively is crucial to ensure cost-efficiency and sustainability. Dairy farms typically operate around the clock, with energy-intensive processes such as milking, refrigeration, and lighting. Understanding the unique energy needs and patterns of dairy farms can help in choosing suitable energy tariffs and adopting energy-saving measures. Additionally, the fluctuating nature of energy prices makes it vital for dairy farms to regularly review and compare energy deals to optimise their operational costs. By doing so, they can focus on producing high-quality dairy products while maintaining their commitment to environmental responsibilities.

How much does energy cost for a dairy farm?

There is no published price list for dairy farms. What a dairy farm 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 dairy farms?

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 dairy farms 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 dairy farms?

There is no single answer. Suppliers price business contracts individually rather than publishing standard tariffs for dairy farms, 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 dairy farms use energy

Dairy farms are characterised by continuous operations, often requiring significant energy to maintain milk production and storage. Key energy-consuming areas include milking systems, cooling and refrigeration units to keep milk fresh, and barn lighting, especially in winter months. Machinery for feed processing and water heating also contribute to energy usage. Understanding these patterns can help dairy farms identify areas where efficiency improvements can be made, such as upgrading to more energy-efficient equipment or implementing renewable energy solutions like solar panels.

What affects energy bills for dairy farms

Several factors impact the energy bills of a dairy farm:

• Seasonal variations: Colder months typically increase heating and lighting needs.
• Equipment efficiency: Older or poorly maintained equipment can consume more energy.
• Operational hours: Extended milking and processing times lead to higher consumption.
• Energy tariffs: The type and timing of tariff chosen can influence costs significantly.
• Location: Rural locations may face different rates compared to urban areas.

How to compare tariffs

When comparing energy tariffs for a dairy farm, consider the following checklist:

• Review current energy usage and peak demand times.
• Check if the tariff offers flexibility for off-peak usage.
• Assess the contract length and any early termination fees.
• Look for tariffs that offer incentives for renewable energy use.
• Ensure the supplier provides reliable customer service support.

Gas or electricity: what matters most

On a dairy farm, electricity is predominantly used for milking machines, cooling systems, and lighting. Gas may be utilised for water heating and other specific heating needs. The balance between gas and electricity usage will depend on the farm's specific processes and equipment. Evaluating the cost-effectiveness and efficiency of using gas versus electricity can help in choosing the right energy mix for the farm.

How switching works

Switching energy suppliers for a dairy farm can be straightforward if approached methodically:

1. Review current energy usage and identify needs.
2. Research and compare potential suppliers and tariffs.
3. Notify your current supplier of your intention to switch.
4. Set up a new contract with your chosen supplier.
5. Ensure a seamless transition by coordinating the switch date.
