Garden centre energy suppliers, tariffs and costs

Garden centres, with their sprawling spaces and diverse energy needs, face unique challenges when it comes to managing energy costs. The energy requirements of a garden centre can vary significantly depending on the size of the operation, the range of products sold, and the facilities offered. From maintaining the right temperature in greenhouses to ensuring efficient lighting in retail areas, energy plays a critical role in daily operations. Understanding these energy needs and finding the right energy plan is crucial for reducing overheads and enhancing sustainability.

How much does energy cost for a garden centre?

There is no published price list for garden centres. What a garden centre 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 garden centres?

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 garden centres 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 garden centres?

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

Garden centres typically exhibit varied energy usage patterns, often hinging on their operational scale and the range of services they offer. Key areas of consumption include lighting, heating, and cooling systems, particularly in greenhouses where maintaining optimal growing conditions is essential. Retail areas also require efficient lighting solutions to highlight products and create an inviting customer experience. Additionally, energy is needed for outdoor equipment and administrative functions. Understanding these patterns helps in managing energy use effectively, allowing garden centres to optimise their energy strategy.

What affects energy bills for garden centres

Several factors influence the energy bills of a garden centre, including:

• Seasonal variations, which affect heating and cooling needs.
• The size and layout of the centre, impacting lighting and heating efficiency.
• Types of plants and products, influencing temperature control requirements.
• Operational hours and peak times of activity.
• Equipment efficiency and maintenance practices.
• Local climate conditions affecting heating and cooling demands.

How to compare tariffs

When comparing energy tariffs for your garden centre, consider the following checklist:

• Assess your current energy usage and identify peak periods.
• Look for tariffs that offer flexibility to cater to seasonal demands.
• Consider the benefits of fixed vs. variable rate plans.
• Check for any hidden fees or contract termination charges.
• Evaluate the supplier's customer service and support options.
• Explore green energy options for sustainability goals.

Gas or electricity: what matters most

For most garden centres, electricity is a primary energy source due to the extensive use of lighting and climate control systems. However, gas may also play a significant role, especially in heating greenhouses and other spaces during colder months. Balancing the use of gas and electricity effectively can lead to improved cost management and improved energy efficiency. It's important to evaluate the specific needs of your centre to determine the optimal mix of energy sources.

How switching works

Switching energy suppliers for your garden centre involves the following steps:

1. Review your current energy contract and note the end date.
2. Gather recent energy bills to understand usage patterns.
3. Research and compare different energy suppliers and tariffs.
4. Contact your chosen supplier to initiate the switch.
5. Provide necessary details and confirm the switch date.
6. Ensure the final meter reading is taken on the switch date.
