What is the ECO4 scheme?
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. Its aim is to support vulnerable households with energy-saving measures at no cost to them, so homes become more efficient and more comfortable.
It goes beyond boilers. Eligible homes can get a package of insulation and heating improvements.

What customers say about working with us
Reviews from SW3 customers on solar and battery work.
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.

ECO4 questions
Why can't I just get a replacement gas boiler?
The ECO scheme is designed by the government to improve the most energy-inefficient properties. It requires the fabric of your home (walls, floors and roof) to be considered before a heating system is replaced. If all the insulation work has been done, a heating upgrade may be possible, though further scheme restrictions may apply.
What heating upgrades are typical?
Upgrading from electric room heaters to an efficient air source heat pump. Upgrading from inefficient electric storage heaters to an efficient air source heat pump. Upgrading from a non-condensing gas boiler to an efficient A-rated combi boiler.
What if I do not want every measure the installer recommends?
To be eligible, your property must meet the minimum EPC band improvement. The measures the installer identifies meet that requirement and must be installed for you to qualify.
Can I get the ECO grant and choose my installer?
ECO is not a grant scheme. Payments are made directly to the installer for the work completed in your home, and only installers that meet the government's accreditation requirements can carry it out. That keeps the standard of work high.
Why do I need ventilation measures?
When a property is insulated it needs adequate airflow throughout, so ventilation measures may be required.
How do I find my EPC rating?
Look up your property on GOV.UK's Find an energy certificate page.
