What is ECO4?
ECO4 is the fourth phase of the government's Energy Company Obligation. It launched in August 2022 and was set to run until 31 March 2026. Rules and deadlines can change, so ask us what applies today.
It supports households that need help with energy bills by funding energy-saving measures and heating improvements. It goes well beyond boilers. Homeowners with a low EPC rating can apply for a full package of upgrades.
- Cost-free measures for eligible households.
- Free survey of your home from a matched installer.
- A full package, not just a boiler.

What our customers say
Real reviews from homes we've fitted.
Stellar experience from start to finish. Chris, Paul, Sherri and anybody on their team has been extremely competent and nice to deal with. They inspected my property, provided a detailed survey suggesting a sensible setup, with good explanations about how it would all work together and they provided a very reasonable quote, with highest quality materials. By the end of the day they were able to get all my apps set up and properly configured with the energy provider.
I'd highly recommend using SW3 for my new solar panels and battery purchase and install. The entire process was so smooth, from initial booking to the quick installation on the day. Thank you.
SW3 installed an excellent system to our home and provided exceptional service. They prioritise customer satisfaction. They strived to meet even our bespoke requests and their rates are fair. Kudos to Chris for the wonderful process from the initial discussion til post-installation, and for always keeping me updated. Kudos also to Matt who installed our system and who was really hardworking and knowledgeable. I would definitely recommend SW3 to everyone.

Questions people ask us
Why can't I just get a replacement gas boiler?
The ECO scheme is designed to improve the most energy-inefficient homes. It requires the fabric of the property (walls, floors and roofs) to be considered before the heating system is replaced.
If all insulation work has been done, a heating upgrade may be possible, although more restrictions can apply. Typical upgrades are:
- Electric room heaters to an efficient air source heat pump
- Inefficient electric storage heaters to an efficient air source heat pump
- A non-condensing gas boiler to an efficient A-rated combi boiler
What if I do not want all the measures the installer recommends?
To be eligible, your home must meet the minimum EPC band improvement. The measures the installer identifies meet that requirement and must all be installed.
How do I find my EPC rating?
Visit GOV.UK and use the Find an energy certificate service.
Can I get the ECO grant and choose my installer?
ECO is not a grant scheme. Payments go directly to the installer, based on the work completed in your home. Only installers meeting government accreditation requirements are used, so work meets a high standard.
Why do I need ventilation measures?
When a property is insulated it needs enough airflow, so ventilation measures may be required.
