School energy suppliers, tariffs and costs

In the UK, schools are unique entities when it comes to energy consumption, requiring a tailored approach to managing their energy needs. With varied building sizes, operating hours, and energy-intensive activities, schools face distinct challenges in balancing cost efficiency and sustainability. From classrooms to sports facilities, the energy demand can fluctuate significantly throughout the year, necessitating a strategic approach to energy management. Understanding the nuances of energy usage within schools is crucial for ensuring that they operate efficiently while also adhering to budgets and environmental goals.

How much does energy cost for a school?

There is no published price list for schools. What a school 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.

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, a school 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.

Do schools pay 5% VAT on energy?

Only in part. HMRC lists “school and university residential accommodation” as domestic use, so energy for boarding houses and other residential accommodation is charged at the 5% reduced rate with no Climate Change Levy. Teaching blocks, offices, sports halls and kitchens are non-qualifying, so a day school pays 20% plus the levy unless its usage is small enough to fall under the low-usage limits. Where a boarding school has one supply for the whole site, the 60% rule applies: 60% or more qualifying use means the whole supply is charged at 5%; below that it is split, and the school gives the supplier a certificate declaring the qualifying percentage.

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 a school 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 schools 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 schools?

No supplier specialises in schools 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 School

Schools typically experience varied energy usage patterns depending on their size and facilities. Most schools see peak electricity demand during weekdays, especially in the mornings and early afternoons when classes are in session. Additionally, energy consumption can increase during particular periods, such as examination times or when hosting events. Heating is another significant component, particularly in older buildings that may not have modern insulation. Energy needs may also vary seasonally, with higher heating demands in winter and increased cooling requirements in summer.

What affects bills for School

Several factors can influence energy bills for schools, including:

• Building size and age, which can affect insulation and energy efficiency.
• Number of students and staff, impacting overall energy consumption.
• Type and number of electrical equipment used, such as computers and laboratory devices.
• Heating systems and their efficiency.
• Renewable energy installations, such as solar panels, which may manage costs effectively.

How to compare tariffs

When comparing energy tariffs for schools, consider the following checklist:

• Evaluate current energy usage patterns and peak demands.
• Check for tariffs that offer lower rates during off-peak hours.
• Consider the benefits of fixed versus variable rate contracts.
• Look for suppliers offering green energy options.
• Assess any additional services or support offered by energy suppliers.

Gas vs electricity considerations

For schools, both gas and electricity play vital roles, though their importance can vary. Electricity is essential for lighting, computing, and other educational technologies, while gas is primarily used for heating and cooking. Schools with older buildings may rely more heavily on gas for heating, whereas newer constructions might integrate more efficient electric heating solutions. Balancing the use of both resources can lead to more cost-effective and environmentally friendly operations.

Switching process overview

Switching energy providers for a school involves several steps:

1. Review your current energy contract terms and end date.
2. Gather energy usage data for accurate comparison.
3. Research and select a new supplier that meets your needs.
4. Notify your current supplier of your intention to switch.
5. Coordinate with the new supplier to ensure a seamless transition.
