From ECO4 to commercial solar: a new opportunity for UK installers

With ECO4 now coming to an end, many installers are asking the same question: What’s next?

The answer is clear. Commercial solar presents a significant and growing opportunity, which is why HDM Energies is helping installers make that transition with confidence.

We’re enabling UK businesses to adopt solar with no upfront cost, unlocking a new wave of demand and creating a powerful pipeline of commercial projects for our installer partners.

While ECO4 provided funding for residential properties, we make solar accessible to commercial organisations by funding the equipment and installation costs. Many businesses want lower energy bills but can’t or don’t want to commit to the upfront investment - that’s where we step in. We remove the financial barrier, creating opportunities that installers can deliver today.

HDM Energies has secured a £100 million funding package with Paragon Bank to deploy commercial solar projects across the UK.

This creates a ready-made opportunity for installers looking to:

• Replace lost ECO4 pipeline
• Expand into commercial projects
• Grow revenue without managing complex funding models themselves

If you already have strong installation expertise, this is a natural next step.

Moving into commercial solar can feel like a significant shift, but it doesn’t need to be. We provide a structured pathway that supports you across:

• Sales conversations
• System design
• Project delivery
• Long-term customer success

There’s no need to worry about product selection either. Everything is specified and supplied through our sister company, HDM Solar, providing high-quality hardware for every project and allowing you to focus on what you do best: Installation.

Our onboarding process is designed to help teams familiar with domestic energy efficiency and tariffs transition into the commercial sector with confidence.

Step one: Simple onboarding

Step two: Upskill your team
