Car garage energy suppliers, tariffs and costs

Car garages in the UK face unique energy challenges due to their operational requirements. With a need for both power-intensive equipment and consistent lighting, these businesses must carefully manage their energy consumption to maintain profitability. Understanding how to optimise energy use can lead to improved cost management and a more sustainable operation. By evaluating consumption patterns, garages can make informed decisions about their energy suppliers and tariffs. This page offers insights into energy usage for car garages, factors affecting their bills, and how they can effectively compare tariffs and switch providers to ensure they are finding the right option.

How much does energy cost for a car garage?

There is no published price list for car garages. What a car garage 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, a car garage 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 a car garage 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 car garages 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 car garages?

No supplier specialises in car garages 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 Car garage

Car garages typically have a diverse energy usage profile, largely driven by the need to power machinery, tools, and lighting. During working hours, energy demand can be high, particularly when operating equipment such as lifts, air compressors, and diagnostic tools. Additionally, heating and ventilation systems may contribute to energy consumption, especially during colder months. Understanding these patterns is crucial for garages aiming to manage their energy costs efficiently. By identifying peak usage times, garages can explore strategies to reduce consumption and opt for tariffs that cater to their specific needs.

What affects bills for Car garage

Several factors can influence the energy bills for a car garage, including:

• Operating hours – longer hours increase energy use.
• Equipment efficiency – older machinery may consume more energy.
• Lighting – reliance on high-intensity lighting can raise costs.
• Seasonal variations – heating requirements in winter can spike usage.
• Number of service bays – more bays typically mean higher energy demands.
• Building insulation – poor insulation can lead to increased heating costs.

How to compare tariffs

Car garages looking to compare energy tariffs can follow this checklist:

• Assess your current energy usage patterns to understand needs.
• Gather recent energy bills for accurate comparison.
• Identify peak operating times and required power levels.
• Research available tariffs that cater to business energy needs.
• Check for dual fuel options if using both gas and electricity.
• Consider fixed vs variable tariffs based on business stability.
• Evaluate the potential for renewable energy solutions.

Gas vs electricity considerations

For car garages, electricity is often more critical due to the need to power various tools and lighting systems. However, gas may still play a role, particularly if used for heating or specific machinery. The decision between prioritising gas or electricity will depend on the specific operational needs of the garage. It's important to evaluate the cost-effectiveness of each energy source and consider any potential benefits of switching to more energy-efficient or renewable options.

Switching process overview

Switching energy suppliers for a car garage involves several steps:

1. Review current contract terms and identify the switching window.
2. Gather detailed usage data to inform decisions.
3. Research and compare potential new suppliers and tariffs.
4. Contact chosen supplier to initiate the switch.
5. Coordinate with the current supplier to ensure a smooth transition.
6. Confirm the switch date and manage meter readings as required.
7. Monitor the first few bills to ensure accuracy post-switch.
