No. The zero-rate for installing energy-saving materials applies to domestic property, not to a commercial system over 50 kWp, so VAT is charged at the standard rate on a commercial installation. This is indicative, not tax advice; confirm your position with a qualified accountant or tax adviser.

A plain account of how VAT sits on a commercial solar system, and why the cost most VAT-registered businesses actually carry is the net figure, not the headline one.
- How VAT applies to commercial solar and recovery for a VAT-registered business. The zero-rate for installations applies to residential, not commercial, so commercial buyers should confirm their own position.

VAT is not a funding route in its own right. It is the tax that sits on top of the price, and on a commercial system it is usually recoverable, so it changes the real cost of going capex rather than the decision to go capex. We set it out here because it is one of the questions a finance director rightly asks early, and because the answer for a commercial buyer is different from the one people have heard for homes.
The short version: the zero-rate that applies to solar on a domestic property does not apply to a commercial installation, so VAT is charged at the standard rate on a commercial system. For a VAT-registered business that input VAT is generally recoverable, subject to its own VAT position, which means the figure that matters to the business case is the net cost after recovery. Buying outright still keeps the most of the return; VAT simply affects the cash you lay out and the cash you reclaim, not the merit of owning the asset.
The mechanics, plainly.
On a commercial solar installation, VAT is charged at the standard rate. The residential zero-rate for the installation of energy-saving materials is a domestic relief and does not extend to a commercial system over 50 kWp, so a commercial buyer should not expect a zero-rated invoice. Where your business is VAT-registered and the system serves taxable business activity, the VAT charged on the installation is input tax that is generally recoverable through your normal VAT return, subject to your own position, your partial-exemption status if any, and the use to which the electricity is put. The practical effect is that the cash cost of the asset is laid out up front and the VAT element comes back through the return, so the business ultimately carries the net cost rather than the gross.
One point worth stating plainly: Alectrona is VAT-registered, so VAT is charged at the standard rate on our work, and for a VAT-registered business that input VAT is generally recoverable through your normal VAT return, subject to your own position. The VAT on the equipment and any subcontracted labour in the supply chain runs through the same recovery. We do not reclaim or account for VAT on your behalf. Reverse-charge rules for construction services and your registration status are matters for your accountant, and the recoverable position should be confirmed before you commit rather than assumed from this page.
Who it suits, and the trade-offs.
VAT recovery is not automatic and it is not universal. It turns on your registration status, whether the electricity feeds taxable business activity, and any partial-exemption position your business carries, so a business that is not VAT-registered, or is only partly taxable, may not recover all of it, or any of it. That is precisely why this belongs with your accountant rather than your installer: we can state how VAT applies, but only a qualified adviser can confirm what your specific business recovers and when. None of this changes the underlying recommendation. Capex remains the route that keeps the most of the return, because you own a 25-year asset and keep the saving; VAT and capital allowances govern the cost you carry to get there.
Treat VAT as a cash-flow and net-cost question, not a reason to choose one funding route over another. It sits alongside capital allowances as the tax detail that shapes the real outlay on a bought system, and it should be modelled into your numbers from your own figures, confirmed with your adviser, before any decision.

VAT for commercial solar: common questions
Generally, yes, where your business is VAT-registered and the system serves taxable business activity, the input VAT on the installation is recoverable through your normal VAT return. It is subject to your own position, including any partial exemption, so it is not automatic. Confirm what your business actually recovers with your accountant before you commit.
Yes. Alectrona is VAT-registered, so VAT is charged at the standard rate on our work, and for a VAT-registered business that input VAT is generally recoverable through your normal VAT return, subject to your own position. We do not reclaim or account for VAT on your behalf, so confirm your recoverable position with your accountant before you commit.
No. VAT affects the cash you lay out and the net cost you ultimately carry, not the merit of owning the asset. Capex stays the route that keeps the most of the return; VAT and capital allowances simply shape the real outlay on a bought system. Model it into your own figures and confirm the recoverable position with your adviser.
