Solar North | I’ve Had an ECO4 Installation in Wales – What Now?

The ECO4 scheme has brought a wave of government-backed green energy improvements to households across Wales. For many, it’s a great opportunity: free insulation, heat pumps, and even small solar panel systems. But what happens after the installation? And are you really set up to make the most of it?

A Good Start – But Often Not the Full Picture

The ECO4 installations often provide a decent solar setup. But here’s what we’re seeing time and time again:

No export registration: Many solar panel systems aren’t properly registered with the DNO or energy supplier. That means you can’t get paid for excess electricity you export back to the grid.
No battery storage offered: This limits your ability to store power for evening use – one of the biggest benefits of solar.

For a scheme designed to tackle fuel poverty and reduce emissions, this is a missed opportunity.

The Real Opportunity: Retrofitting and Registering

To truly unlock the value of your ECO4 system, we’ve been helping customers take a few extra steps:

Battery retrofits: Adding battery storage to your system can drastically improve your self-use and reduce your bills.
Re-registering systems: If your panels weren’t properly registered, we can guide you through re-registration so you can access export tariffs and start earning from your solar.
Expanding panel systems: In many cases, small ECO4 arrays can be expanded to provide more meaningful generation.

These upgrades make a difference. With proper registration and battery storage, ECO4 recipients can store energy for evening use, earn money from exported electricity, and even run their homes more independently.

Installation and Handover: Still Room for Improvement

A recurring frustration is the handover process. Many customers report:

Lack of guidance on how to use or monitor their new systems.
Missing paperwork or certificates that are essential for insurance, registration, or future modifications.
No clear next steps after the install team leaves.

We believe ECO4 can go further by improving this transition from installation to active, informed use.

The Takeaway: ECO4 Is a Strong Start – Make It Last

ECO4 is a great start to improving energy efficiency and reducing fuel bills in Welsh homes. But with a few tweaks and add-ons, it can become much more than a free upgrade—it can be a foundation for long-term savings and energy independence.

If you’ve had an ECO4 install and want help registering, retrofitting, or just understanding your system, we’re here to help.
