Is home battery storage zero VAT without solar? Yes. A standalone home battery, one charged only from the grid with no solar panels involved, is zero-rated for VAT in the UK when a business installs it for you. That relief has applied since 1 February 2024 and is scheduled to run until 31 March 2027. The detail that trips people up is where the 0% actually lands: it attaches to the installation, not to the battery as a product on a shelf.
So if an installer quotes you to supply and fit a standalone battery today, the VAT line should read 0%. If you buy the same battery as a box to wire in yourself, you pay the standard 20% on the hardware and cannot get it back. This page sets out what HMRC zero-rated, the gap between an installed system and DIY parts, whether a retrofit to older solar counts, and what the relief is worth against your payback.
Is a home battery zero VAT without solar?
Yes. A professionally installed standalone battery, charged from the grid with no solar attached, is zero-rated for VAT in the UK from 1 February 2024 to 31 March 2027. HMRC added grid-charged battery storage to the energy-saving materials zero rate. The relief covers installation by a business in a home, not a battery you buy as goods to fit yourself. It is a UK VAT relief, so it applies the same in England, Scotland, Wales and Northern Ireland.
What did HMRC actually zero-rate?
Immediately before the February 2024 expansion, a home battery only reached the zero rate if it was installed at the same time as solar panels or another qualifying microgeneration system. A battery bought on its own to store cheap overnight grid electricity stayed at standard-rate VAT. That changed. HMRC now lists three battery scenarios that qualify for the zero rate:
- installing a standalone battery to store electricity taken from the grid;
- retrofitting a battery to store electricity from solar panels, a wind turbine or a water turbine you already own;
- installing a battery that stores electricity from both a microgeneration system and the grid.
The first scenario is the one that matters here: grid-only, no solar, zero-rated. It sits inside the wider energy-saving materials relief, which is why the timing is fixed rather than permanent.
| Period | VAT on an installed home battery |
|---|---|
| Immediately before 1 February 2024 | 20% (unless installed alongside solar) |
| 1 February 2024 to 31 March 2027 | 0% |
| From 1 April 2027 (scheduled) | 5% |
Source: HMRC VAT Notice 708/6 and the internal manual VENSAV3061, which confirm the zero rate applies up to 31 March 2027, after which energy-saving materials revert to the reduced rate of 5%.
Installed or bought: where does the 0% actually apply?
This is the part most summaries skip, and it decides whether the relief reaches you at all. The zero rate is a relief on the installation of an energy-saving material, not on the material as a retail product. HMRC’s rule is blunt: supply energy-saving materials without installing them and the supply is standard-rated.
In practice that gives you three situations.
| How you buy it | VAT you pay | Why |
|---|---|---|
| One business supplies and fits the battery | 0% on the qualifying battery supply and installation | A single supply of installing an energy-saving material in a home; separate or unrelated work on the same invoice can carry its own VAT rate |
| You buy the battery as goods and fit it yourself | 20% on the hardware | Goods supplied without installation are standard-rated, and you cannot reclaim it |
| You buy the battery, then pay an electrician only to fit it | 20% on the hardware, 0% on the fitting labour | The installation service of an energy-saving material can be zero-rated, but the box you already bought kept its 20% |
The clean way to get 0% on the whole battery is a single supply-and-install from one company that sources the battery and fits it as one job. Split the job and the hardware you bought at retail keeps the 20% it was sold with, even if the electrician who wires it in zero-rates their labour. As a homeowner you are not VAT registered, so that 20% on the hardware is a cost you carry, not something you claim back later.
People sometimes ask whether an installer can buy a battery back off them, or invoice a self-bought battery through, to pull the whole thing down to 0%. The relief follows who actually supplies the installed battery, not the paperwork around it. If the installer genuinely supplies and fits the battery as a single job, that qualifying supply is zero-rated; a contrived buy-back on a box you already own does not change what was supplied. The straightforward route is to have the installer supply and fit it from the start.
None of that makes DIY the wrong call on cost. A DIY route can still come out cheaper, but compare complete, compliant system costs rather than the battery price alone. The specific VAT relief in the headlines is an installer relief, so a DIY buyer should weigh the real numbers rather than assume the 0% follows the battery home.
The VAT treatment is also separate from the rules that govern the work itself. Zero-rating does not remove the electrical, Building Regulations or grid-connection obligations. A grid-connected battery still needs the correct notification to your DNO, either a G98 notification for a battery inverter rated at 3.68kW or below on a single phase, or a G99 application above that, and the mains connection is notifiable electrical work that a competent installer should carry out. Getting the tax right is not the same as getting the installation signed off.
Does a retrofit battery added to old solar qualify?
Yes. Adding a battery to solar panels you already own is one of the three scenarios HMRC lists for the zero rate, on the same supply-and-install condition as a standalone battery. You do not have to replace or upgrade the panels to get it. If an installer fits a battery to your existing array between now and 31 March 2027, that installation should be zero-rated.
The same logic runs the other way too. A battery installed at the same time as a new solar system has been eligible for years, so the 2024 change did not alter that. What it added was the standalone and retrofit-to-existing routes, which is exactly the case where a homeowner has no solar in the picture yet.
What does the zero rate change in your payback?
Assume the installer’s price before VAT is £4,500 and stays the same across the three rates. The figures below show what each rate adds to that price, as an illustration rather than a market average, so your own quote will differ.
- At the old 20% treatment, the same job would carry about £900 of VAT, taking it to roughly £5,400.
- At today’s 0% rate, you pay the £4,500 with no VAT added.
- At the 5% rate scheduled from April 2027, the same job would carry about £225 of VAT, taking it to £4,725.
So the zero rate is worth roughly £900 against the old treatment and about £225 against the scheduled 5% rate, on this example. A battery earns its keep by charging when grid electricity is cheap and discharging when it is dear, and the payback runs into years rather than months. Knocking £900 off the up-front price shortens that payback directly, because it is a straight reduction in the money you have to earn back. It is the cleanest saving on the whole project: no tariff assumptions, no degradation curve, just a lower invoice.
The practical read is timing. If you are going to have a battery installed anyway, having it done before 31 March 2027 captures the 0% rather than the 5% that is currently scheduled to follow. That is a modest difference on a single battery, and not a reason to rush a bad system, but it is real money on the invoice.
What should you check on your quote?
The zero rate is the installer’s responsibility to apply correctly, but it is your invoice, so it is worth reading the VAT line before you sign. The relief covers the qualifying battery supply and installation, so check the 0% is set against the battery work itself; separate or unrelated work bundled onto the same invoice can still carry a different rate.
- The quote is for supply and installation, not a battery sold as goods to be fitted separately.
- If the installer is VAT-registered, the qualifying installation reads 0%, not 20% and not 5%. A smaller installer below the VAT registration threshold does not charge VAT at all, so you pay none either way.
- The property is a home or qualifying residential building, which is the condition the relief is written for.
- If a quote shows 20% VAT on a standalone or retrofit battery installation, ask why before accepting it, because either the treatment is wrong or you are being sold goods only.
If an installer insists the battery must be standard-rated, point them at HMRC VAT Notice 708/6. The standalone and retrofit routes are named in it explicitly, so there is a source to settle the question rather than a debate.
What happens after 31 March 2027?
The zero rate is time-limited. HMRC’s guidance sets it to run to 31 March 2027, after which energy-saving materials, batteries included, are scheduled to revert to the 5% reduced rate rather than the old 20%. So even if you miss the 0% window, an installed battery is still due to be far cheaper on VAT than it was before February 2024.
Two caveats worth holding. First, the 5% figure is what current guidance points to, and a future government could extend the zero rate, change the reduced rate, or set different terms. Treat the April 2027 date as the scheduled position, not a guarantee. Second, this is the VAT position only. It says nothing about whether a battery suits your tariff, your consumption, or your house, which are separate questions worth answering before the tax one.

The figures in the payback section are worked illustrations on a single stated price, not a market survey, and your own quote is what settles the numbers. The VAT rules above are current as of July 2026 and are the position I would check again before any large purchase, because reliefs with end dates are exactly the kind that get revised.
