Business Energy VAT: Rates, Relief and How to Claim
Business energy VAT is often treated as a fixed cost, but that is not always correct. In the UK, the standard VAT rate is 20%, yet some fuel and power supplies qualify for the reduced 5% rate. That includes certain domestic or residential uses, charity non-business use, and some low-consumption sites that fall within HMRC’s de minimis thresholds.
That matters because incorrect VAT treatment can push energy costs up unnecessarily. HMRC’s internal guidance also notes that many suppliers default new non-domestic customers to standard rating unless evidence for reduced treatment is provided, which means some eligible organisations do not get the right VAT rate until the issue is reviewed.
For businesses, landlords, charities and mixed-use sites, understanding the rules can make a real difference to invoice accuracy and cash flow. It can also affect other charges on the bill, including Climate Change Levy in qualifying cases.
What is the VAT rate on business energy?
For most business gas and electricity supplies, the VAT rate is 20%. HMRC’s current VAT guidance confirms that the standard VAT rate in the UK is 20%, while electricity and gas for domestic and residential use, or for non-business use by a charity, are charged at 5%.
It is also important to understand that VAT on a qualifying supply is not limited to the unit rate alone. HMRC says the reduced rate can apply to inseparable charges made by the supplier up to and including the meter, and that standing charges form part of the gas or electricity supply. Where the supply qualifies, the whole bill, including the standing charge, is reduced-rated.
When can a business pay 5% VAT on energy?
A commercial site can qualify automatically for the reduced rate if its energy use stays within HMRC’s de minimis thresholds. For electricity, that is not more than 33 kWh per day or 1,000 kWh per month. For piped gas, it is not more than 145 kWh per day, 4,397 kWh per month, or 150 therms per month. HMRC states that supplies within those limits are treated as domestic use even when supplied to a business customer.
This point is often missed by small offices, workshops, kiosks, small retail units and lightly used sites. If your usage falls below those thresholds, the reduced rate should apply and HMRC says you do not need a certificate for de minimis supplies.
The reduced rate also applies where energy is supplied for genuine domestic or residential use. HMRC includes houses, flats, children’s homes, hospices, care settings, self-catering holiday accommodation, religious communities, and school or university residential accommodation within that definition.
Just as importantly, HMRC says some premises do not count as residential accommodation for this purpose. Hotels, inns, hospitals and prisons are specifically excluded, so businesses in those sectors should not assume the 5% rate applies simply because people sleep on site.
A charity can pay 5% VAT on fuel and power used for its non-business activities. HMRC’s charity guidance states that fuel and power in buildings used by charities for non-business purposes is reduced-rated, and the fuel and power notice says that where a charity does not make a charge, its activities are generally non-business.
This is a key distinction. Charity status alone is not enough in every case. If a charity carries out both business and non-business activity on the same premises, the energy use may need to be apportioned.
Mixed-use sites are one of the biggest areas of confusion. HMRC says that if 60% or more of the fuel or power is for qualifying use, the whole supply can be treated as qualifying use and charged at the reduced rate. If qualifying use is less than 60%, the supplier should charge 5% on the qualifying portion and 20% on the non-qualifying portion.
This rule can be relevant to care homes, student accommodation blocks, religious sites, mixed commercial and residential buildings, and charities using one meter across different activities.
How to claim reduced VAT on business energy
The practical route to claiming reduced VAT is usually straightforward, but it needs to be done properly.
Start by reviewing how the energy is used and whether the site falls into one of the recognised qualifying categories. The main ones are low usage within de minimis thresholds, domestic or residential accommodation, charity non-business use, or mixed-use with a calculable qualifying percentage.
HMRC says a mixed-use certificate should include the supplier’s name and address, the customer’s details, the premises address, the exact qualifying percentage, and a signed declaration from a responsible officer confirming the accuracy of the facts. HMRC also says suppliers must make reasonable checks, and customers should keep copies of the certificate and supporting documents.
HMRC’s internal manual adds that certificates are the usual way of evidencing qualifying use, even though they are not legally required if there is alternative evidence the supplier accepts. It also says a separate certificate should be provided for each supply, and a new one should be issued when you move premises or switch supplier.
If the supplier has been charging 20% where the site qualifies for 5%, ask them to update the account and review earlier invoices. HMRC’s internal fuel and power manual says suppliers may accept backdated certificates and agree to adjust VAT, but whether they do so is a commercial decision between the supplier and the customer, subject to the normal VAT rules on errors and adjustments.
Can VAT-registered businesses reclaim VAT on energy bills?
Yes. If your business is VAT registered, HMRC says you can reclaim VAT on items bought for use in the business through your VAT Return, provided the normal input tax rules are met. That includes utility bills, but only to the extent they relate to business use and you hold a valid VAT invoice.
If any part of the bill relates to personal use, you can only reclaim the business proportion. HMRC gives the example of someone working from home who uses 20% of the floor space as an office and can therefore reclaim 20% of the VAT on utility bills.
If your business makes both taxable and exempt supplies, partial exemption rules may restrict how much input VAT you can recover. If you use the VAT Flat Rate Scheme, HMRC says you generally cannot reclaim VAT on purchases except for certain capital assets over £2,000.
Does reduced VAT also affect Climate Change Levy?
Often, yes. HMRC’s Climate Change Levy guidance says that supplies excluded from the main rates of CCL include domestic use and charity non-business use, and that these exclusions are based on the same qualifying-use principles used for VAT on fuel and power.
For mixed-use supplies, HMRC applies a similar 60% rule for CCL. If domestic or charity use is at least 60% of total use, the whole supply can be treated as excluded from the main rate of CCL. If it is less than 60%, the non-qualifying portion remains taxable, and the customer should provide a VAT certificate showing the qualifying percentage.
That means a VAT review can sometimes uncover two separate savings opportunities on the same energy account.
Common mistakes businesses make
A common error is assuming all commercial sites must pay 20% VAT. HMRC’s de minimis rules show that some low-usage business sites should be billed at 5% automatically.
Another is confusing reduced-rate eligibility with VAT recovery on the VAT Return. These are separate issues. A site might correctly be billed at 20% and still allow a VAT-registered business to reclaim some or all of that VAT as input tax. Equally, a site might be entitled to 5% but still need to give the supplier evidence first.
A third is assuming public EV charging qualifies for reduced VAT if the electricity volume is low. HMRC is clear that electricity used at public charging points is always standard-rated, regardless of quantity.
Why this matters for invoice accuracy
VAT is one of several charges that can materially affect the true cost of business energy. Nationwide Utilities’ current service offering includes business energy procurement, energy management, bill validation and overcharge recovery support, which makes VAT accuracy a natural part of a wider invoice and contract review. Nationwide Utilities is a London-based business energy consultancy founded in 2000 and describes itself as supporting large and multi-site organisations with procurement, utility management and sustainable solutions.
For organisations with mixed-use buildings, multiple sites, charity activities, residential elements or unusually low usage, a VAT review is not just an admin exercise. It is part of making sure the bill reflects the actual use of the premises and the correct tax treatment.
Making business energy VAT work for you
Business energy VAT is simple in principle but easy to get wrong in practice. Most businesses pay 20%, but some premises qualify for 5% because of low usage, residential use, charity non-business activity, or mixed-use rules. Where the wrong rate has been applied, the right evidence and the right supplier process can make a meaningful difference to future billing and, in some cases, historic overcharges as well.
FAQs
What is the VAT rate on business energy in the UK?
Why is my business energy VAT 5% instead of 20%?
The most common reasons are that your site uses less than HMRC’s de minimis threshold, the premises are treated as residential accommodation, or the energy is used by a charity for non-business purposes. In mixed-use cases, the whole supply can also be reduced-rated if qualifying use is 60% or more.
What are the de minimis thresholds for reduced VAT on energy?
Does a mixed-use property qualify for 5% VAT?
It can. If 60% or more of the energy is used for qualifying use, HMRC says the whole supply can be charged at the reduced rate. If the qualifying use is below 60%, the bill should be apportioned between the reduced rate and the standard rate.
How do I claim reduced VAT from my energy supplier?
Can I reclaim VAT on business energy through my VAT Return?
Does public EV charging qualify for the 5% VAT rate?
No. HMRC says electricity supplied through public EV charging points is always standard-rated for VAT, regardless of the amount supplied.
