Energy is one of the biggest fixed costs a small firm cannot easily switch off, so any small business energy deal that promises to shave it deserves a look. Wire: energy and operating costs reports that EDF and solar installer Heliotec have launched a partnership aimed squarely at cutting energy bills for smaller businesses.
The tie-up brings together a major energy supplier and a rooftop solar specialist, with the pitch being that on-site panels let a firm generate part of its own electricity rather than buying every unit from the grid. Rooftop solar systems typically last around 25 years, which is what turns a large upfront outlay into a long-run saving.
Why does this matter now? Business energy contracts do not enjoy the price cap that protects households, so many SMEs are still carrying rates set during the volatile years and feel every increase in full. Generating your own power is one of the few levers a small firm controls directly, alongside efficiency and smarter tariffs.
Who this helps, and who it does not
Solar suits businesses with the right roof and a daytime demand pattern: workshops, small manufacturers, farm units, garages, salons and shops that run equipment while the sun is up. If you use most of your power in the evening, or you rent premises with a landlord who controls the roof, the maths is weaker and worth checking before you commit.
EDF and Heliotec are not the only route. Business owners shortlisting options should also look at Octopus Energy for Business, Wiltshire-based Good Energy and Stroud’s Ecotricity, all UK suppliers with a renewables focus, plus larger installers and finance-led providers. Naming several is the point: solar is a competitive market, and quotes vary widely by roof, region and system size.
The money question
The barrier for most small firms is the upfront cost, not the technology. That is where funding matters. Some suppliers offer power purchase agreements, where a third party owns the panels and you buy the output at an agreed rate. Others expect you to buy the kit outright, which is where asset finance can spread the cost over several years so the savings help cover the repayments.
Before you sign, it is worth reading the small print the way you would any other overhead. Solar sits alongside the wider squeeze small firms face, from staffing to the business rates pressures many high street operators are lobbying to reform, and it should be judged as one part of that cost picture rather than a silver bullet. If cash flow is already tight, understanding how small firms fund investment matters as much as the panels themselves.
The practical takeaway
Get at least three quotes, including EDF and Heliotec but not only them. Ask each installer for an estimated annual generation figure, a payback period based on your actual usage, and a clear breakdown of ownership, warranty and maintenance. Check your roof’s age and orientation, confirm any planning or landlord permissions, and compare buying outright against a finance or power purchase deal. Solar can genuinely lower a bill you cannot otherwise escape, but only when the numbers are run against your own consumption, not a headline average.
