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.

Can Smart Thermostats Work with Heat Pumps? Here’s What You Need to Know

By Mariel • October 9, 2025
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.

Smarter Heating and Energy Savings with Heat Pumps and Solar Panels

Air Source Heat Pumps: Understanding the Costs and Potential Savings

By Mariel • October 16, 2024
Home heating accounts for 38% of gas use in the UK, contributing to considerable CO2 emissions, with the average gas boiler emitting 2.2 tonnes of CO2 annually. An air source heat pump, powered by renewable electricity, offers a more sustainable alternative, which is why the government is promoting its adoption. The UK government aims to phase out gas boilers by 2035 as part of its plan to achieve net-zero emissions by 2050. To support this transition, grants are being offered to help households install air source heat pumps and other low-carbon heating solutions, encouraging homeowners to switch from their old gas and oil boilers to cleaner, greener options.

Key Considerations for Heat Pump Installation in Your Home

By Mariel • April 12, 2024
Various heat pump variants, such as air source, ground source, and hybrid systems, offer efficient and environmentally friendly heating options for your home, all while being cost-effective. Preparing your home for a heat pump involves several key considerations: Insulation and Energy Efficiency : Before installing a heat pump, assess your home's insulation and overall energy efficiency. Upgrading insulation and improving energy efficiency can significantly reduce energy costs and ensure optimal performance from your heat pump. Available Space: Determine if your property has enough space for the type of heat pump you're considering, whether it's an air source, ground source, or hybrid system. Different heat pump types require specific space considerations, so ensure your property meets these requirements. Planning Permissions: Check with your local authority to understand if your heat pump installation requires planning permission. Regulations can vary, so it's important to align your plans with local guidelines to avoid any legal issues. Radiators and Pipework: Evaluate your existing radiators and pipework to determine if they're compatible with a heat pump. Heat pumps can work with various heating systems, including radiators and underfloor heating. In some cases, minor adjustments or upgrades may be necessary for optimal compatibility. Maintenance and Servicing: Plan for regular maintenance and servicing of your heat pump to ensure it operates efficiently and maintains longevity. Access to qualified technicians for servicing and addressing any issues promptly is essential for optimal heat pump performance. By addressing these factors, you can better prepare your home for a heat pump installation, ensuring maximum efficiency and effectiveness of your heating system.

Heat Pump Energy Labels

By Mariel • March 14, 2024
Heat pumps are required to display an energy label indicating their efficiency level, ranging from dark green (most efficient) to red (least efficient). Since September 26, 2015, all newly manufactured heat pumps must come with an EU product label. Additionally, the installer is responsible for providing a package label that showcases the efficiency based on various components within the heating system. Any heat pumps certified by the Microgeneration Certification Scheme must include a product label upon sale, and the installer must also provide a package label. Failure to have a product label may result in the heat pump being ineligible for Government grants. Air-source heat pumps are among the most efficient methods for heating homes, resulting in significantly lower running costs compared to conventional heating systems. According to the Energy Saving Trust, heating a home with gas costs around 4.6p per kWh, while standard electric heaters cost between 9 and 16p per kWh. A typical air source heat pump may run at approximately 4.7p per kWh, potentially dropping to 2.3p if utilizing Economy 7 electricity or switching to our GoElectric tariff. 

How Often Should an ASHP be Serviced?

By Mariel • February 29, 2024
An air source heat pump typically requires an annual check by the owner and periodic maintenance by a professional installer every 3-5 years to ensure efficient operation and prolong its lifespan.
