Solar Panel VAT Relief in 2026: How to Claim Your 0% Rate

Solar panel installations in UK residential properties carry a 0% VAT rate in 2026, saving Lancashire homeowners £1,000 to £2,000 on a typical system compared to the standard 20% rate. The relief applies automatically – your qualified installer charges you zero VAT, and you do not need to file any paperwork or make a separate claim. Here is exactly how it works, who qualifies, and what else is covered beyond solar panels.

What the 0% VAT Rate Covers

The zero rate applies to the supply and installation of energy-saving materials (ESMs) in residential properties. For solar, this covers the panels themselves, the inverter, mounting hardware, cabling, the labour to install everything, scaffolding as part of the installation, and battery storage systems installed at the same time as solar panels or added later.

The relief also extends well beyond solar. The full list of qualifying energy-saving materials includes solar panels (PV), solar thermal panels, heat pumps (air source and ground source), insulation (loft, wall, floor), draught stripping, hot water system insulation, heating controls (thermostats, TRVs, zone valves), heat batteries, wind turbines, water turbines, and electrical battery storage.

This means if you are installing solar panels, a battery, and upgrading your insulation at the same time, all of it qualifies for 0% VAT. The cumulative saving can be substantial.

How Much Lancashire Homeowners Save

Here are the VAT savings on common Lancashire installations in 2026:

• 4kW solar PV system (£6,500 before VAT) – Save an estimated £1,300 (would have been £7,800 at 20% VAT)
• 4kW solar + 5kWh battery (£9,500 before VAT) – Save an estimated £1,900
• 6kW solar + 10kWh battery (£13,000 before VAT) – Save an estimated £2,600
• Air source heat pump (£10,000 before VAT) – Save an estimated £2,000
• Loft insulation (£500 before VAT) – Save an estimated £100
• External wall insulation (£8,000 before VAT) – Save an estimated £1,600

The prices your installer quotes should already reflect the 0% VAT rate. If a quote shows 20% VAT on solar panels or other qualifying ESMs, query it with the installer – they may have made an error, or the property may not qualify (see eligibility below).

Who Qualifies for the 0% Rate

The qualifying criteria are straightforward:

The property must be residential. Houses, flats, bungalows, park homes, and houseboats all qualify. Commercial properties do not. If you run a business from home, the VAT relief still applies to your domestic installation provided the panels are on your home, not a separate commercial building.

The installation must be in the UK. All Lancashire and Greater Manchester properties qualify, as do all other UK addresses.

There is no income test. Unlike many grants, the VAT relief is available to homeowners who meet the property and eligibility criteria (no income test, but other requirements apply), savings, or benefits status. Whether you own a studio flat in Preston city centre or a country house in the Ribble Valley, the same 0% rate applies.

Both owned and rented properties qualify. If a landlord installs solar panels on a rental property, the 0% rate applies. If a homeowner installs them on their own home, the rate applies. The key is that the property must be used as someone’s home.

Previously, the relief was restricted to properties where the materials cost no more than 60% of the total installation cost. This condition was removed in 2024, so all qualifying installations now get the 0% rate regardless of the cost split between materials and labour.

How to Claim: You Don’t Have To

The 0% VAT rate is applied at the point of sale by your installer. There is no separate claim form, no HMRC application, and no paperwork for the homeowner. Your installer charges you the net (ex-VAT) price, and the VAT line on your invoice shows 0%.

Your installer is responsible for correctly applying the rate and accounting for it in their VAT returns. If you have any doubts about whether VAT has been correctly applied, check your invoice. It should clearly state the VAT rate as 0% and reference the qualifying legislation.

If you receive a quote or invoice showing 20% VAT on a qualifying ESM installation in a residential property, raise it with the installer. They may need to correct their invoicing. If they insist 20% applies, check with another installer or contact HMRC for clarification – in most cases, the 0% rate should apply.

Common Situations and Exceptions

Adding a battery to an existing solar system. If you already have solar panels and want to add battery storage later, the battery installation also qualifies for 0% VAT. The battery does not need to be installed at the same time as the panels.

Solar panels on a new build. New builds are zero-rated for VAT anyway (the entire build is typically 0% VAT), so the ESM relief does not change anything for new homes. The relief is most valuable for existing homes where renovation work would normally attract 20% VAT.

Holiday lets and second homes. The property must be someone’s residence. A holiday cottage in the Ribble Valley that is used solely for short-term lettings may not qualify. If you live in the property for part of the year, it may qualify as a residence – seek advice from your installer or an accountant if you are unsure.

Buying panels yourself and hiring a separate installer. If you purchase solar panels directly from a supplier and hire a separate installer to fit them, the VAT treatment can be more complex. The panels as a product may attract standard VAT, while the installation labour may be zero-rated. This is another reason to use a single installer who supplies and fits the system – the 0% rate applies to the whole package.

How Long Will the 0% Rate Last?

The 0% VAT rate on energy-saving materials was introduced in April 2022 and is currently legislated to run until March 2027. After that, it will revert to the reduced 5% rate unless the government extends the zero rate further.

There is widespread expectation that the 0% rate will be made permanent or at least extended beyond 2027, given the government’s net-zero commitments. However, nothing is guaranteed, and the possibility of a return to 5% VAT is a reason to install sooner rather than later.

On a £6,500 solar installation, the difference between 0% and 5% VAT is £325. The difference between 0% and 20% is £1,300. If you are planning a solar or heat pump installation, the current 0% rate represents the best VAT position you are likely to see.

Combining VAT Relief with Other Grants

The 0% VAT rate stacks with other financial incentives. You can benefit from 0% VAT plus up to £7,500 in government grants for a heat pump, 0% VAT plus government energy efficiency schemes funding for insulation, and 0% VAT on solar panels plus export tariff income for surplus electricity. These are separate benefits from different sources, and claiming one does not affect your entitlement to the others.

For a Lancashire homeowner installing a heat pump and solar panels together: the heat pump costs £10,000 before VAT, the solar system costs £6,500 before VAT. With 0% VAT, you save an estimated £3,300 compared to 20% VAT. With the government grant (currently up to £7,500, subject to eligibility) on the heat pump, your total out-of-pocket cost drops from £19,800 (at 20% VAT, no grant) to £9,000. That is a saving of over £10,000.

Does the 0% VAT apply to EV charger installation?

No. EV chargers are not currently classified as energy-saving materials under the VAT relief legislation. A home EV charger installation attracts the standard 20% VAT rate. However, if the charger is installed at the same time as solar panels, only the charger element carries VAT – the solar system remains at 0%.

Can I claim the VAT back if I paid 20% in error?

If your installer charged 20% VAT on a qualifying installation, they should issue a corrected invoice. The refund comes from the installer, not from HMRC. Contact them, explain that the installation qualifies for the 0% rate, and request an adjusted invoice and refund of the overcharged VAT.

Does the 0% rate apply to repairs and maintenance on existing solar panels?

The 0% rate covers supply and installation of energy-saving materials. Routine maintenance, repairs, and panel cleaning are considered services rather than installation of materials and typically attract the standard 20% VAT rate. Replacing a faulty panel or inverter with a new one may qualify for 0% as it involves supplying a new ESM, but this is a grey area – ask your installer to check.
