Dental practice energy suppliers, tariffs and costs

Dental practices in the UK have unique energy needs due to their reliance on specialised equipment and a comfortable environment for patients. With the considerable energy consumption associated with dental chairs, sterilisation equipment, air conditioning, and lighting, it's crucial for dental practices to efficiently manage their energy use. Understanding the specific energy requirements and exploring competitive energy tariffs can help practices reduce their running costs without compromising on the quality of care. YourUtilities.co.uk is dedicated to helping dental practices navigate the complexities of energy consumption and find appropriate energy solutions that suit their operational needs.

How much does energy cost for a dental practice?

There is no published price list for dental practices. What a dental practice 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 dental practices?

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 dental practices 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 dental practices?

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

Dental practices typically have a distinctive energy usage pattern due to their operational requirements. The use of high-powered dental chairs, sterilisation units, and imaging equipment contributes to significant electricity consumption. Additionally, maintaining a comfortable environment for patients necessitates the use of heating or air conditioning systems, which can further impact energy usage. Lighting also plays a vital role as dental procedures demand precise visibility, necessitating the use of bright lighting solutions. Understanding these patterns can help practices make informed decisions regarding their energy supply and efficiency improvements.

What affects energy bills for dental practices

Several factors can influence the energy costs for dental practices, including:

• Operational hours: Longer hours can lead to increased energy consumption.
• Equipment usage: High usage of electrical equipment such as autoclaves and imaging devices.
• Seasonal changes: Heating in winter and cooling in summer can affect bills.
• Energy tariffs: The choice of energy tariff can significantly impact costs.
• Building efficiency: Older buildings may have poor insulation, leading to higher energy usage.

How to compare tariffs

When comparing energy tariffs for a dental practice, consider the following checklist:

• Assess current energy usage patterns to understand needs.
• Identify peak operational hours and align with tariff offers.
• Look for tariffs offering competitive rates for business users.
• Check for any additional fees or contract terms that may affect costs.
• Consider fixed vs variable tariffs based on stability needs.

Gas or electricity: what matters most

For dental practices, electricity is typically more critical than gas, due to the reliance on electrically powered dental and sterilisation equipment. However, gas may still play a role in heating the premises, especially in larger practices. Balancing the use of gas and electricity, while ensuring energy efficiency, can help manage overall energy costs effectively.

How switching works

Switching energy suppliers for a dental practice involves several steps:

1. Review your current energy contract and termination terms.
2. Gather usage data to understand your needs.
3. Compare alternative suppliers and tariffs tailored for businesses.
4. Choose a new supplier and agree on a contract.
5. Coordinate the switch date to ensure seamless energy supply.
