Most UK homeowners currently pay 0% VAT on solar panels, covering both equipment and installation labour, thanks to a relief on energy-saving materials that runs until 31 March 2027. After that date, the rate is set to rise to 5% rather than jump straight back to the standard 20%, but there are specific conditions that determine whether you actually qualify for the 0% rate right now.
Who Actually Qualifies for the 0% Rate
The relief covers residential properties broadly defined – houses, flats, care homes, hospices, houseboats and static caravans all qualify, as do buildings used solely for charitable purposes such as village halls and community centres. Commercial properties, including most businesses, hospitals and prisons, are excluded from this particular relief and pay the standard 20% VAT rate on solar installations instead, though commercial buyers have separate capital allowances available (see our guide on tax incentives for solar installation in the UK) that can offset this.
The Condition That Most Often Catches People Out
You can only get the 0% rate if you purchase your equipment from the same company that installs it – buying panels separately from one supplier and hiring a different installer to fit them results in 20% VAT on the equipment purchase, even though the installation itself might still qualify. This is a genuinely easy mistake to make if you’re trying to save money by sourcing panels independently, and it’s worth confirming explicitly with any installer before going down that route.
Battery Storage: The Rules Have Changed and Now Cover More Scenarios
Since February 2024, standalone battery installations qualify for 0% VAT even when retrofitted after your solar panels were originally installed – previously, only batteries fitted at the same time as the panels themselves received the relief. This matters for anyone who installed solar some years ago and is only now considering adding a battery, since it removes what used to be a meaningful cost disadvantage to adding storage later rather than upfront.
What Happens When the 0% Rate Ends
From 1 April 2027, the rate is currently set to rise to 5% rather than the full standard 20% rate – a meaningful increase from 0%, but still a substantially reduced rate compared with most other goods and services. On a £7,100 system, that difference works out to roughly £355 in additional VAT compared with installing before the deadline, which is worth factoring into timing if you’re already considering solar and were planning to wait.
| Period | VAT rate | Approx. VAT on a £7,100 system |
|---|---|---|
| Now – 31 March 2027 | 0% | £0 |
| From 1 April 2027 | 5% (currently planned) | ~£355 |
Make Sure Your Quote Actually Reflects 0% VAT
Reputable installers should apply the 0% rate automatically to eligible residential quotes, but it’s worth checking your written quote explicitly states the VAT treatment rather than assuming it’s correct. If a quote shows 20% VAT for what should be a qualifying residential installation, query it directly – this is sometimes a genuine oversight rather than a deliberate charge, but either way it’s worth catching before you sign.
Frequently Asked Questions About VAT on Solar Panels
Is VAT really 0% on solar panels right now in the UK?
Yes, for most residential installations purchased and installed by the same company, until 31 March 2027. This covers both the equipment and the installation labour, not just one or the other.
Does the 0% VAT rate apply to commercial solar installations?
No – this particular relief is specifically for residential and charitable-use buildings. Commercial properties pay standard 20% VAT on solar installations, though they can typically access capital allowances that provide a different form of tax relief instead.
Do I pay VAT on a standalone battery installed without new solar panels?
Since February 2024, standalone battery retrofits qualify for 0% VAT even without accompanying new panels, provided the property is residential and the standard purchase-and-install-together condition is met.
Should I rush to install solar before the VAT rate changes?
If you were already planning solar and have the budget ready, installing before 31 March 2027 avoids the planned increase to 5%, saving a modest but real amount. It’s not worth rushing a decision you weren’t otherwise ready to make, but it’s a reasonable factor to weigh if you’re already close to committing.
