What VAT rate do I pay on business electricity and gas?

Most business energy is charged at the standard 20% VAT rate. You pay the reduced 5% rate on small amounts (up to 33 kWh a day of electricity or 145 kWh a day of gas) or on domestic or charity non-business use, and the 60% rule applies to mixed use.

The three rates

UseVAT
Ordinary business use above the small-use limits20%
Small quantities (de minimis) or qualifying domestic / charity non-business use5%
Qualifying domestic / charity non-business electricity in Great Britain, 1 Oct 2026 to 30 Jun 20270% (temporary)

The rules are in HMRC VAT Notice 701/19: fuel and power, which also gives the zero rate's end date of 30 June 2027 (HMRC first announced 31 March 2027; Budget 2026 extended it). The temporary zero rate was first explained in HMRC Revenue and Customs Brief 10 (2026).

The small-use (de minimis) limits

If your average use per premises is no more than 33 kWh a day of electricity (about 1,000 kWh a month) or 145 kWh a day of piped gas (about 4,397 kWh a month), the reduced rate applies. Details in the 33 kWh de minimis limit.

Domestic and charity use

Energy used in a home, or by a charity for non-business activities (a church hall used for worship, say), can be reduced-rated. Charity business activity, such as hiring out a hall, is standard-rated unless the small-use limits apply. See VAT for charities.

The 60% rule for mixed use

  • If 60% or more of the supply is qualifying use, the whole supply is reduced-rated.
  • If less than 60%, only the qualifying portion is reduced-rated and the rest is standard.

Worked example

A community hall's net electricity bill is £400 for the month, and 45% of use is non-business. Qualifying: £400 × 45% = £180 at 5% = £9. The other £220 at 20% = £44. Total VAT = £53.

If it were 65% non-business, the whole £400 would be reduced-rated: £400 × 5% = £20. (Between 1 October 2026 and 30 June 2027 the qualifying electricity would be 0%, so the 65% case would be £0, and the 45% case would be just the £44 on the business share.)

How you get the lower rate

The supplier will not apply it automatically in mixed-use cases. You usually give a signed declaration: see the reduced-rate VAT declaration. Use our VAT and CCL calculator to see the effect on a bill.

Business use stays at 20%

The temporary zero rate does not cover ordinary business use, which stays at 20%. See whether zero VAT applies to your business. Gas is unaffected by it.

Most VAT-registered businesses can reclaim the 20% as input tax, so the rate matters most to those who cannot: see reclaiming VAT.

Common mix-ups

  • "My bill shows 5% but I run a business." It may be right if your use is under the small-use limits, but check, because a wrong rate can lead to a later correction.
  • "Charities pay no VAT." Not quite: they pay 5% (0% on qualifying electricity in Great Britain from 1 October 2026 to 30 June 2027) on non-business use, and 20% on business activity above the limits.
  • "VAT is only on the energy." VAT is charged on the whole bill including standing charges and the Climate Change Levy, which is why the CCL line matters: see how CCL affects your bill.

Gas follows the same 5% test but at the higher 145 kWh a day limit, and the temporary zero rate does not apply to it.

Next steps

  1. Look at the VAT line on your bill and check the rate.
  2. Work out your daily average use against 33 and 145 kWh.
  3. If you qualify, send a declaration to your supplier.
