Maximise Your Home Energy Savings with the ECO4 Extension

Mariel • March 6, 2026

Why Acting Early Matters

Funding isn’t unlimited, and eligibility depends on factors like property type, energy performance, and household income. Securing support sooner increases the chance of covering high-impact upgrades and planning improvements that best suit your home. Energy efficiency measures not only lower bills but also enhance long-term property value and contribute to environmental goals.

What Improvements Are Covered

ECO4 supports a wide range of energy efficiency upgrades, including:


  • Air source heat pumps for low-carbon heating
  • Loft and cavity wall insulation to reduce heat loss
  • Draught-proofing to improve comfort


Air source heat pumps capture heat from the air outside and convert it into energy to heat your home efficiently. With the scheme covering a significant portion of installation costs, switching to renewable heating has become far more accessible for qualifying households.

Key Changes Under the Extension

The ECO4 extension introduces updates designed to improve reach, fairness, and impact:

1. Updated Eligibility Criteria

Funding now prioritises households most in need, including lower-income families, residents on qualifying benefits, and homes with EPC ratings D to G. This ensures support reaches homes where improvements deliver the greatest financial and environmental impact.


2. Revised Funding Limits

High-impact upgrades such as full insulation packages and air source heat pumps may receive increased financial support, while smaller individual measures have tighter caps. This allows more households to benefit overall.


3. Whole-Home Improvements Encouraged

Combining measures—insulation, draught-proofing, and low-carbon heating—maximises energy efficiency, reduces emissions, and increases property value over time.


4. Simplified Application Process

Clearer guidance and structured processes make it easier to understand eligibility and funding options. While navigating ECO4 can still be complex, the extension provides more detailed resources to support homeowners.


5. Focus on Long-Term Savings

The scheme now places greater emphasis on upgrades that deliver substantial long-term energy savings, helping households lower bills and contribute to sustainability goals.

Navigating ECO4 funding can feel overwhelming, but you don’t have to manage it alone. Darlington Heat Pumps specialises in helping homeowners understand their eligibility, identify the most suitable upgrades, and manage the installation process from start to finish. With professional guidance, you can maximise available funding, complete upgrades efficiently, and transform your home into a warmer, more energy-efficient space before the December 2026 deadline.

The ECO4 extension is a unique chance to make meaningful energy efficiency improvements. Acting now ensures you can access financial support, improve home comfort, and reduce your energy bills. Contact Darlington Heat Pumps today to explore your options and make the most of this government scheme.

If you've been thinking about replacing your current heating system with an air source heat pump, there's good news. The UK Government has announced an increase to the Boiler Upgrade Scheme (BUS), giving eligible homeowners even more financial support towards the cost of installation. From 21 July 2026, qualifying households replacing an oil or LPG heating system can now receive £9,000 through the Boiler Upgrade Scheme—an increase of £1,500 from the previous grant of £7,500. This update is intended to make renewable heating more affordable and encourage more households to move away from fossil fuel heating.

When most people think of smart thermostats, they imagine them paired with a gas boiler — turning the heating up from your phone or letting the system learn your daily routine. But what if you’ve switched to a more efficient system, like an air source heat pump (ASHP)? Can the two work together? The short answer is yes — and when they do, you get the perfect mix of comfort, control, and energy savings.
