Had a bad experience with an ECO4 installer? We’re here to help.
At Celtic Green Energy, we’ve been receiving more and more calls from frustrated homeowners left with faulty or underperforming heat pump and solar installations under the ECO4 scheme.
Has your installation team let you down?
Are they ignoring your calls, emails – or worse – telling you the problems aren’t their fault?
You’re not alone. And we’re here to put things right.
We’re the professionals who fix what others got wrong.
Solar PV systems generating little or no energy
Systems installed without proper heat-loss calculations
Poorly sized or incorrectly located heat pumps
No aftercare, no follow-up, and zero accountability
Installers who ignore your emails and won’t return your calls
Damaged property, roof leaks, or incomplete work
ECO4 installations are meant to meet the same high standards as paid-for systems – including full property assessments and proper commissioning. But far too many homeowners are left with systems that are:
Undersized or misconfigured
Poorly installed by rushed subcontractors
Delivered with no guidance, no documentation, and no support
If you’ve had this experience, you are not alone – and you’re absolutely right to speak up. We’ll help you get the system you were promised.

Many homeowners feel they “shouldn’t complain” because the work was government-funded. But remember:
💡 ECO4 is funded by taxpayers – and installers are paid thousands for each job.
💡 You have the legal right to expect proper work and working systems.
If you’re cold, confused, or ignored — don’t feel guilty. Get help.
If you’ve had a heat pump or solar installation through ECO4 and it’s not working or your installer won’t return your calls let us step in.
