VAT is a consumption tax levied on most goods and services in the UK, including the energy used to power your home. It is a percentage added to the net cost of your energy supply, contributing to the overall price you pay. HM Revenue & Customs (HMRC) is responsible for setting and enforcing VAT rules in the UK.
The standard VAT rate in the UK is 20% for most goods and services, a rate that has been in place since 4 January 2011. However, domestic energy supplies (both gas and electricity) have historically benefited from a reduced VAT rate.
Currently, a reduced rate of 5% applies to domestic gas and electricity supplied to residential properties. From 1 October 2026, there will be a temporary change: VAT on domestic electricity in Great Britain will be reduced to 0% until 31 March 2027. During this period, VAT on domestic gas bills will remain at 5%. This temporary measure aims to provide relief to households during the winter months. In Northern Ireland, the VAT rate on domestic electricity will remain at 5%.
The VAT rate applicable to domestic energy is already included within the unit rates charged per kilowatt-hour (kWh) and the daily standing charges on your energy bill. This means you will not typically see VAT listed as a separate line item; it is factored into the prices you pay for your energy consumption and connection. Energy suppliers collect this tax and then pass it on to HMRC.
The reduced VAT rate on domestic energy is a deliberate policy decision aimed at making essential energy more affordable for households. This approach has a significant historical context in UK tax policy.
When VAT was first introduced in the UK in 1973, domestic supplies of fuel and power were zero-rated (0%). This changed on 1 April 1994 when VAT was introduced on domestic energy at a rate of 8% by the Conservative government. There was an initial intention to increase this to the standard rate (then 17.5%) in April 1995, but this proposal was defeated in Parliament.
The 5% rate we have seen for many years was introduced by the Labour government from 1 September 1997, reducing it from the previous 8%. At the time, this was the lowest rate permissible under EU VAT rules. Following Brexit, Great Britain gained more flexibility in setting its own VAT rates, which enabled the recent temporary reduction of VAT on domestic electricity to 0%.
The power to set VAT rates for goods and services in the UK, including energy, rests with HM Revenue & Customs (HMRC) and government policy. While Ofgem, the energy regulator, ensures that energy suppliers comply with billing regulations, including the correct application of VAT, the actual rates are determined by government policy and implemented by HMRC.
Even at a reduced rate, VAT contributes to the overall cost of your energy bills. Understanding how it interacts with other factors, such as the energy price cap, can help you manage your household finances.
The energy price cap, set by Ofgem, limits the maximum unit price and standing charge that suppliers can charge for gas and electricity on standard variable tariffs. The 5% VAT rate is factored into these energy price cap calculations.
The government has estimated that the temporary reduction of VAT on electricity to 0% from 1 October 2026 will reduce the yearly Ofgem Price Cap by approximately £45 for an average household. This change is already built into the price cap rates for 1 October to 31 December 2026. However, it is important to remember that while the VAT reduction helps, the overall price cap can still change due to other market factors, such as wholesale energy costs.
To truly understand the impact of VAT on your energy costs, it is helpful to look at your total energy consumption. Since VAT is included in your unit rates and standing charges, the more energy you use, the more VAT you effectively pay.
Consider reviewing your total energy consumption to see the overall impact of VAT on your bill. Exploring energy efficiency measures, such as improving insulation or upgrading appliances, can help reduce your overall energy usage. This, in turn, will reduce the total amount of VAT you pay, as it is a percentage of your overall bill. For example, understanding the running cost of an air source heat pump can help you make informed decisions about heating your home efficiently. You might also want to investigate if you are eligible for an air source heat pump grant to help with installation costs.
VAT is an indirect tax, meaning that while energy suppliers collect it, the cost is ultimately borne by the end consumer.
For domestic energy supplies, householders are the ones who pay the reduced VAT rate. This applies to gas and electricity used in your home. Most households in the UK are eligible for this reduced rate on their domestic energy supplies.
It is crucial to distinguish between VAT rules for domestic and business energy, as they often differ significantly. Energy supplied to businesses and non-domestic premises is generally subject to the standard UK VAT rate of 20%.
However, there are exceptions where businesses may qualify for the reduced 5% rate. For instance, if a property has both residential and commercial elements (mixed-use properties), specific rules apply. If 60% or more of the energy supplied is for qualifying domestic use, the entire supply may be charged at the reduced 5% VAT rate. If less than 60% is domestic, your supplier will usually apply 5% VAT to the domestic portion and 20% to the business portion. Additionally, small businesses with very low energy usage (below certain "de minimis" thresholds) may automatically qualify for the 5% VAT rate.
For domestic energy, the reduced 5% VAT rate (or temporary 0% for electricity) is generally applied to all households. While there are no broad exemptions for domestic energy bills, certain charities using energy for non-business activities may qualify for the reduced rate. Additionally, the installation of some energy-saving materials, such as heat pumps, insulation, and solar panels, currently benefits from a 0% VAT rate until 31 March 2027, reverting to 5% from 1 April 2027.
If you use energy for both domestic and business purposes at the same property, the VAT rate applied depends on the proportion of domestic use. If 60% or more of your energy consumption is for domestic purposes, the entire supply is typically charged at the reduced 5% VAT rate. If domestic use is less than 60%, your supplier will usually apply 5% VAT to the domestic portion and 20% to the business portion.
The 'de minimis' threshold allows small businesses with low energy consumption to qualify for the reduced 5% VAT rate, even if they are not primarily domestic. For electricity, this threshold is typically 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 or 4,397 kWh per month. HMRC treats supplies below these thresholds as domestic for VAT purposes.
VAT on domestic energy bills is generally included within the unit rates and standing charges, rather than being itemised separately. This means you will not usually see a distinct "VAT" line on your bill. Instead, the prices per kWh and the daily standing charges you are quoted and pay already have the applicable VAT rate factored in. If you have questions about how VAT is applied to your specific bill, you can contact your energy supplier for clarification.
