Most of what is sold to businesses as a solar grant is not a grant. It is either tax treatment of capital expenditure, an export payment, or a finance product with a grant shaped name. That does not make any of it worthless, but it does mean the first job is to establish which of the three you are being offered, because they behave completely differently.
Solar panel grants for businesses: the three things called a grant
A grant is money you are given and do not repay, usually against conditions and usually time limited and regional. Tax relief reduces what you owe on expenditure you have already made, which is worth real money but only if the business is profitable. An export payment pays you for electricity you send to the grid, which is income rather than funding. Sales material blurs all three. Ask which one is being described and what happens to the number if the business makes no profit this year.
Government grants for solar panels for business UK: how to check a scheme is real
A real scheme has an administering body, published eligibility criteria, an application process and a closing date, and it can be found on that body's own site rather than on an installer's. If the only evidence of a grant is an installer's page, treat it as marketing. Regional and devolved schemes are the most common genuine ones and the most likely to have changed since a brochure was printed, so check the date on the source.
Capital allowances on solar panels: the part most businesses actually use
Expenditure on plant and machinery may attract capital allowances, and the rules and rates change. This is the mechanism that most commonly reduces the real cost of a commercial array, and it is the one an installer is least qualified to advise on. Take it from current guidance and from your accountant, and get the treatment confirmed before the business case is signed off rather than after.
Export payments are income, and they are conditional
The Smart Export Guarantee obliges larger suppliers to offer a tariff for exported electricity, and rates differ between suppliers, so the export tariff is shopped for separately from the installation. Eligibility depends on the installation being certified and metered correctly, which is a reason the certification question is not paperwork. Treat export as a modest income line rather than as the case for the project.
Questions people ask about commercial solar panel grants
Are there free solar panels for businesses?
Offers described that way are normally third party ownership: somebody else owns the array on your roof and sells you the electricity under a long agreement. There is no capital cost and no ownership. Read what it does to future roof works and what the electricity price does over the term before treating it as free.
Can a business claim solar panel capital allowances?
Capital allowances may apply to qualifying plant, and the treatment depends on the business and the rules in force. It is an accountant's question, not an installer's, and it should be confirmed in writing before the business case is approved.
Do business solar panel grants UK schemes require a certified installer?
Almost always, and export payments do too. Confirm the certification requirement in the scheme's own documents before choosing a contractor, because retro fitting certification after the work is not possible.
Where should I look for current solar grants for business?
The administering body's own website and the relevant national or devolved government pages. Scotland, Wales and Northern Ireland run separate support, so the answer depends on where the building is.
