Yes, VAT on solar panels is still 0% for UK homeowners in 2026 — but the relief ends on 31 March 2027, and with typical installation lead times running into several weeks, the window to lock in the saving is genuinely closing. This guide cuts through the confusion about what the 0% VAT on solar panels actually covers, how much it saves, what happens after the deadline, and how to tell real urgency from a sales pitch.
What is the 0% VAT on solar panels and who qualifies?
The 0% rate is a government tax relief on the installation of energy-saving materials in UK homes. HMRC's VAT Notice 708/6 sets out the rules: any residential property in Great Britain has qualified since 1 April 2022, with Northern Ireland brought in line from May 2023. You do not apply for it, claim it back, or fill in a form — a qualifying installer simply charges you 0% VAT rather than the standard rate. It applies automatically.
To qualify, the work must be a supply-and-install contract carried out by a VAT-registered installer at your home. Buying panels separately from a retailer and having someone else fit them does not qualify — the 0% rate covers the combined supply and installation as a single job.
What exactly does the 0% VAT cover?
More than most homeowners realise. The relief is not just for the panels themselves — it covers the entire installed system when supplied under one contract. That includes the solar PV panels, inverter, mounting and racking, DC and AC cabling, the generation meter, scaffolding, and labour. If a battery is installed at the same time, that is covered too.
Since 1 February 2024, retrofit batteries also qualify — meaning if you already have solar panels and want to add a battery, that standalone installation attracts 0% VAT in its own right. That was a meaningful rule change; before that date, a battery only qualified if it was part of a brand-new solar install.
What is not covered: repairs, replacement parts on an existing system (such as swapping a failed inverter), or solar panels bought without installation. Maintenance is standard-rated at 20%.
How much does the 0% VAT actually save?
The saving depends on what your system costs. The 0% rate applies to the entire contract price — equipment plus labour — so the bigger the system, the bigger the saving.
- Typical 4kW system (3-bed home), ~£7,000 installed: saves around £350 vs the 5% rate that takes over in April 2027
- Solar plus battery combo, ~£12,000 installed: saves around £600 vs the 5% rate
- Compared to the standard 20% commercial rate: the same £12,000 system would cost £2,400 more — though residential installs will only go to 5%, not 20%, in April 2027
To be precise: after 31 March 2027, the rate is expected to revert to 5% — the reduced rate that applied before 2022 — not the full 20% standard rate. So the urgency is real but not quite as dramatic as some installers imply. On a typical solar-plus-battery system, the difference is several hundred pounds, not thousands. That is still a meaningful sum, but it is worth being clear-eyed about the numbers rather than panicked by them.

When does the 0% VAT on solar panels end — and is the deadline real?
The deadline is real. The 0% rate is currently scheduled to end on 31 March 2027, with 5% VAT applying from 1 April 2027. There has been no government announcement of an extension, though nothing rules one out — future policy is genuinely uncertain.
What makes the urgency genuine is not just the deadline itself, but the lead time between deciding to go solar and panels actually being commissioned on your roof. The full process — from getting quotes, choosing an installer, having a site survey, ordering equipment, obtaining any grid permissions, and booking an installation slot — typically takes between 4 and 10 weeks for a standard residential system. Larger systems requiring a G99 grid application (usually those over 3.68kW per phase, or any system with battery storage) can take longer, since the Distribution Network Operator (DNO) has up to 45 working days to approve a full application.
With demand for solar running at record levels — MCS recorded over 257,000 certified installations in 2025, a 32% increase on the year before — installer slots in early 2027 are likely to fill up well ahead of the deadline. That is not a sales tactic; it is simple maths. If you want panels commissioned before 1 April 2027, starting the process in January or February 2027 is cutting it very fine. Starting now gives you breathing room.
Does 0% VAT apply to a battery added to existing solar panels?
Yes — since 1 February 2024, adding a battery to an existing solar system qualifies for 0% VAT as a standalone installation, right up to the 31 March 2027 deadline. You do not need to be installing new panels at the same time. This was a significant rule change and one that caught many homeowners off-guard before it was clarified.
If you have been sitting on existing panels and wondering whether to add storage, this is worth factoring in. The Energy Saving Trust notes that battery storage typically costs around £5,000 to £8,000, and at 0% VAT that is the full price — versus £5,250 to £8,400 at 5% from April 2027. For more on whether a battery is right for your setup, see our guide to Solar Battery Storage: Do You Actually Need One?
When solar might not be worth rushing for the deadline
Here is the honest bit. The 0% VAT deadline is not a reason to install solar on a house that is not suitable for it. If your roof faces north, is heavily shaded, or needs significant structural work first, the VAT saving will not change the fundamental maths. A few hundred pounds off a poorly-performing system is still a poorly-performing system.
Similarly, if you are planning to move house in the next couple of years, or your finances make a large upfront cost genuinely difficult right now, the deadline is not a sufficient reason to rush. A good decision made calmly in 2027 — even at 5% VAT — is better than a hasty one made under pressure in late 2026.
The deadline is a genuine and useful prompt to act if you were already thinking about solar and your home is suitable. It is not, by itself, a reason to act if the fundamentals do not stack up.
What to check before you book an installer
A few practical points worth confirming before you sign anything:
- Check the quote shows 0% VAT explicitly. Your written quote should clearly state 0% VAT on the supply and installation. If it shows 20% VAT on a residential job, ask the installer to explain — and get it corrected if it is wrong.
- Ask what happens if the installation runs past 31 March 2027. Get a written commitment on how the installer handles a VAT rate change if the job overruns the deadline. This matters for larger or complex installs.
- Use an MCS-certified installer. MCS certification is the standard quality mark for solar installers in the UK. It is also a requirement for accessing the Smart Export Guarantee (SEG), which pays you for electricity you export back to the grid. If you want to know how to make the most of that, our guide to the Best Smart Export Guarantee Rates UK 2026 is a useful starting point.
- Get at least three quotes. Even with a deadline looming, comparing quotes remains the most reliable way to avoid overpaying. For guidance on what to look for, see our step-by-step guide to How to Compare Solar Quotes UK.

Frequently asked questions
Is VAT on solar panels still 0% in 2026?
Yes. The 0% VAT rate on residential solar panel installations is in place until 31 March 2027 under HMRC VAT Notice 708/6. Your installer applies it automatically — there is nothing to claim or apply for.
When does the 0% VAT on solar panels end?
The 0% rate ends on 31 March 2027. From 1 April 2027 it is expected to revert to 5% — the reduced rate that applied before 2022 — unless the government extends the relief. There has been no announcement of an extension.
Does 0% VAT apply to a battery added to existing solar panels?
Yes. Since 1 February 2024, adding a battery to an existing solar system qualifies for 0% VAT as a standalone installation, right up to the 31 March 2027 deadline. You do not need to be installing new panels at the same time.
Will the 0% VAT deadline actually be extended?
Nobody can say for certain. There has been no government announcement of an extension, and the current legislation sets 31 March 2027 as the end date. It is possible the rate is reviewed, but planning around a confirmed deadline is more prudent than hoping for an extension that may not come.
Does the 0% VAT apply to the whole installation cost, including labour and scaffolding?
Yes — when a VAT-registered installer supplies and fits the system under a single contract, the 0% rate covers the full package: panels, inverter, battery (if included), mounting, cabling, scaffolding, and labour. It is not just on the hardware.
