Frequently Asked Questions

What is the ECO4 scheme?

A government-funded initiative that helps low-income and vulnerable households improve their home’s energy efficiency through free upgrades like insulation, boilers and heat pumps.

Homeowners and private tenants receiving certain benefits such as Universal Credit, Pension Credit or Child Tax Credit may qualify, along with those in low-income households.

ECO4 covers a wide range of measures including loft insulation, cavity wall insulation, solid wall insulation, air source heat pumps, first-time central heating and energy-efficient boilers.

Yes, for eligible households the upgrades are installed at no cost. There are no hidden charges or repayment requirements.

Simply reach out to a registered ECO4 installer like Cozyfy. They’ll run a quick eligibility check, arrange a free home survey, and handle the installation from start to finish.

Yes, private tenants can apply, but in most cases the landlord’s permission is required before any work can be carried out.

Most installations are completed within one to three days depending on the type and scale of the upgrade being carried out.

No, receiving an ECO4 grant does not affect your existing benefits, tax credits or any other government support you may be receiving.

Savings vary depending on the upgrade, but households can typically save hundreds of pounds per year on their energy bills after improvements are made.

The ECO4 scheme is currently running until December 2026. We recommend applying as early as possible to secure your free home upgrade before the deadline.
