Grants and funding for solar panels for breweries

There is no single "brewery solar grant" in the UK, and any site promising one is misleading you. What there is instead is a stack of genuine, quantifiable levers, some of them specific to breweries, that together turn a capital cost into a fast-paying asset. Here is how they fit together, and the two claims a lot of installers get wrong.

Capital allowances: the Annual Investment Allowance, not "full expensing"

Solar PV is special-rate plant and machinery for capital allowances (HMRC manual CA22335). That single classification decides everything. It means solar qualifies for the Annual Investment Allowance, which gives a profitable company 100% first-year tax relief on the first £1m of qualifying spend, enough to write off virtually any brewery install in year one, worth up to about 25% of the cost as a corporation-tax saving. It also means solar is excluded from full expensing and from the new 40% first-year allowance, both of which apply to main-rate plant only. If an installer tells you the panels get "full expensing" or "the 40% allowance", they are wrong, and correcting that is one of the simplest ways to check you are dealing with a specialist. Above the £1m cap, solar gets a 50% first-year allowance and then a 6% writing-down allowance on the balance. Take your own tax advice, because the benefit depends on your profits and your position.

The Brewing Climate Change Agreement: a lever unique to your sector

This is the one a generic commercial-solar site never mentions. The brewing sector has a Climate Change Agreement, an umbrella deal run through the British Beer & Pub Association, under which participating breweries commit to energy-efficiency targets in return for a large discount on the Climate Change Levy (CCL), the per-kWh tax on business energy. Under the new six-year scheme that runs to 31 March 2033, CCA holders pay just 8% of the CCL on electricity, a 92% discount, and 11% on gas, an 89% discount. With the CCL main rate at 0.801p/kWh from April 2026, that is a saving of around 0.74p on every liable kWh, roughly £7,000 a year for a brewery using a million kWh of grid electricity.

On-site solar helps your CCA in two separate ways. First, electricity you generate and consume on site is not liable for the Climate Change Levy at all, so every kWh the panels displace removes the levy entirely. Second, self-generated renewable power improves your energy-per-hectolitre figure, which is the metric your CCA target is measured against. One honest caveat: larger regional and national breweries meet the energy-intensity threshold comfortably, but many small craft breweries may not individually qualify, so check your current eligibility with the BBPA rather than assuming you are in the scheme.

Business rates: a saving that lasts to 2035

In England, eligible on-site renewable generation and co-located battery storage are exempt from business rates until 31 March 2035, so adding solar does not increase your rateable value. This is a durable, certain saving distinct from the tax reliefs above. It is England-specific, so breweries in Wales and Scotland should check their own devolved rating rules.

Export income and the routes with no capital outlay

Surplus generation earns money under the Smart Export Guarantee, but rates are supplier-set and move, so we quote a range, typically 12 to 16p/kWh in 2026, and never a fixed figure. For a brewery the prize is self-consumption, not export, because a unit you use on site is worth far more than a unit you sell. Where capital is the obstacle, asset finance and a Power Purchase Agreement both let you install with little or no money up front, and the Industrial Energy Transformation Fund, which some older guides still list, is now closed with no successor.
