Business Renewable Energy in Scotland: What First?

Quick answer

Start from your half-hourly meter data, not from the technology. If your site uses most of its power in daylight, solar PV usually comes first; a battery earns its place when your load peaks in the evening or your network operator limits what you can export; EV charging pays when staff or fleet vehicles park on site; and renewable heat belongs in the plan when fossil heating is due for replacement. For a site-by-site view of what commercial renewable energy can do, see our commercial renewable energy page.

Step 1: Measure before you buy

Most business supplies with a smart or advanced meter record half-hourly data, and it tells you more than any brochure. Three things decide the order of your projects:

• When you use power. Daytime-heavy sites (manufacturing, offices, cold stores running through the day) suit solar first. Evening-heavy sites (hospitality, some retail) need storage to use solar well.
• How big your base load is. The power drawn at 3am, when nothing should be running, is often the cheapest saving on the site — and every kWh you remove makes every renewable system smaller.
• What your connection allows. Your supply capacity and any export limit shape what can be installed before a single panel is priced.

Step 2: The usual order, and why

Solar PV first, when the load is in daylight

Solar is special-rate plant, so full expensing does not apply — a company claims the Annual Investment Allowance on up to £1 million of qualifying spend a year instead, with a 50% first-year allowance above that. Since 24 May 2024 most rooftop arrays on business premises in Scotland have needed no planning application, subject to the Class 6J conditions. Our guide to commercial solar planning permission in Scotland walks through them.

A battery when the load moves out of daylight

A battery stores daytime solar for the evening, shaves peaks, and absorbs output your network operator will not let you export. It is a generator for connection purposes, so it goes into the G98 or G99 application alongside the panels — plan both together rather than adding the battery as an afterthought.

EV charging when vehicles are parked on site

The Workplace Charging Scheme pays up to £500 per socket, capped at 75% of costs, for up to 40 sockets across all your sites, and runs until 31 March 2027. Who can use the chargers depends on who applies: a business must keep them for staff and fleet vehicles, while charities, public sector bodies and small accommodation businesses can let anyone charge. The site needs dedicated off-road parking associated with the premises.

Renewable heat when the boiler is due

Heating is often the biggest energy cost on a site that burns oil or gas, but replacing a working boiler early rarely pays. Plan renewable heat for when the plant is due, and use the time before to cut heat loss. Note that the Boiler Upgrade Scheme applies in England and Wales, not Scotland; in Scotland, Business Energy Scotland's SME Loan Scheme lists renewable heat measures.

Step 3: VAT and cash flow

Business premises pay the standard 20% VAT on solar and batteries — HMRC's 0% rate covers residential accommodation and buildings used solely for a relevant charitable purpose. A VAT-registered business normally reclaims it, so compare quotes ex-VAT and plan the cash flow around paying it first.

The three mistakes that cost the most

• Buying technology before measuring load. A solar array sized without half-hourly data is a guess.
• Treating the SME Loan Scheme as a solar fund. When we checked on 16 September 2026, solar PV was not on its list of measures.
• Designing systems one at a time. Solar, storage and EV charging share one connection; applying for them separately can mean a second, slower grid application.
