Author : Boiler Upgrade | Published On : 17 Mar 2026

With energy bills continuing to rise across the UK, many households are struggling to keep their homes warm without overspending. Heating systems—especially older boilers—can be a major source of inefficiency, leading to higher monthly costs and unnecessary energy waste. If your boiler is outdated, unreliable, or expensive to run, now is the perfect time to consider an upgrade.

The UK Government’s ECO4 (Energy Company Obligation) scheme offers eligible households the opportunity to receive a free boiler upgrade, helping you reduce energy bills and improve home comfort without any upfront costs.

In this comprehensive guide, we’ll walk you through everything you need to know about the ECO4 scheme, including how it works, who qualifies, and how you can apply today.

What Is the ECO4 Scheme?

The ECO4 scheme is the fourth phase of the Energy Company Obligation initiative introduced by the UK Government. It is designed to improve energy efficiency in homes, particularly those occupied by low-income or vulnerable households.

Running until March 2026, ECO4 requires large energy suppliers to fund energy-saving improvements such as insulation, heating upgrades, and boiler replacements.

The main goal is to:

  • Reduce carbon emissions

  • Lower energy consumption

  • Help households save on energy bills

  • Combat fuel poverty across the UK

One of the most valuable benefits of the scheme is the ability to receive a completely free boiler upgrade if you meet the eligibility criteria.
