All You Need to Know About ECO4 in South Wales

Introduction: Why ECO4 is Crucial for South Wales

The ECO4 scheme is a government-backed initiative designed to help households across the UK improve energy efficiency, cut energy bills, and reduce carbon emissions. For homeowners and tenants in South Wales, this presents a unique opportunity to upgrade heating systems, install insulation, and even benefit from renewable energy solutions—all at little to no cost. With South Wales having a mix of older housing stock and areas affected by fuel poverty, ECO4 in South Wales is more important than ever.

Many properties in the region lack proper insulation, leading to heat loss and high energy costs. ECO4 aims to tackle this problem by funding energy-saving home improvements for eligible households.

However, ECO4 is a time-limited scheme, running only until March 2026. This means that South Wales residents must act quickly to secure funding before the programme ends.

Why South Wales Needs ECO4

High Energy Costs and Fuel Poverty

Many households in South Wales struggle with rising energy bills, particularly those in older homes with poor insulation. ECO4 helps reduce energy costs by funding home improvements that improve efficiency and reduce heat loss.

Older Housing Stock with Poor Insulation

South Wales has a large number of traditional stone-built homes and older properties with solid walls that lack cavity wall insulation. This makes them harder to heat and retain warmth, increasing the need for heating assistance under ECO4 in South Wales.

Wales’ Commitment to Net Zero Carbon Emissions

The Welsh Government has ambitious carbon reduction targets, aiming for Net Zero by 2050. By improving home energy efficiency, ECO4 plays a critical role in helping South Wales contribute to this goal.

Who is Eligible for ECO4 in South Wales?

Not everyone qualifies for the ECO4 scheme, but the programme is designed to help low-income and vulnerable households. You may be eligible if:

You own your home or are a private tenant with your landlord’s permission.
Your home has a low Energy Performance Certificate (EPC) rating (D, E, F, or G).
You receive certain government benefits, including:
- Universal Credit
- Child Tax Credit
- Housing Benefit
- Pension Credit (Guarantee or Savings Credit)
- Working Tax Credit
- Jobseeker’s Allowance (income-based)

What Does the ECO4 Scheme Cover in South Wales?

The ECO4 scheme provides comprehensive support for energy-efficient home improvements, ensuring that households in South Wales can enjoy lower energy bills, increased comfort, and reduced carbon emissions. The scheme is designed to fund a wide range of energy-saving measures, tailored to make homes warmer and more sustainable.

Here’s a detailed breakdown of what ECO4 in South Wales covers:

Insulation Upgrades

A well-insulated home is key to improving energy efficiency, keeping heat inside during winter and preventing excessive heat during summer. ECO4 funds several insulation upgrades to help households reduce heat loss and lower energy consumption.

✅ Loft Insulation – As much as 25% of heat in a home can be lost through an uninsulated roof. Loft insulation acts as a thermal barrier, preventing heat from escaping and keeping homes warmer for longer. Proper loft insulation can save homeowners up to £250 per year on heating bills.
✅ Cavity Wall Insulation – Many homes in South Wales have cavity walls, which consist of two layers of brick with a gap in between. Uninsulated cavities allow heat to escape, increasing energy bills. ECO4 funds cavity wall insulation, where insulating material is injected into the gap, reducing heat loss by up to 35%.
✅ Solid Wall Insulation – Older homes, particularly stone-built properties common in South Wales, often have solid walls with no cavity to insulate. ECO4 provides internal or external solid wall insulation, significantly improving heat retention and reducing energy costs.
✅ Underfloor Insulation – Homes with suspended floors can experience heat loss through the ground, making them colder and more expensive to heat. ECO4 offers underfloor insulation, helping to keep homes warmer while reducing draughts and energy waste.

By funding these insulation measures, the ECO4 scheme ensures homes are more energy-efficient, reducing heating costs while improving comfort.

Heating System Improvements

Upgrading an outdated or inefficient heating system is one of the most effective ways to lower energy bills and cut carbon emissions. ECO4 provides funding for various heating improvements, helping homeowners and tenants in South Wales switch to more efficient, cost-effective systems.

✅ New A-Rated Boilers – For eligible households, ECO4 can replace old, inefficient non-condensing boilers with A-rated condensing boilers, which are far more energy-efficient and environmentally friendly. These modern boilers extract more heat from the fuel they burn, reducing wasted energy and lowering heating costs.
✅ High-Heat Retention Electric Storage Heaters – Many homes in South Wales rely on outdated storage heaters that waste energy and provide inconsistent heating. ECO4 funds the installation of modern high-heat retention storage heaters, which store and release heat efficiently, maximising energy savings.
✅ Air Source Heat Pumps – One of the best renewable heating solutions available under ECO4, air source heat pumps extract heat from the air to provide efficient home heating and hot water. This low-carbon alternative can reduce heating bills by up to 50%, making it a smart choice for homeowners looking to cut costs and future-proof their heating system.

By upgrading heating systems, ECO4 ensures homes across South Wales stay warmer, more efficient, and environmentally friendly.

Renewable Energy Installations

The ECO4 scheme doesn’t just focus on insulation and heating—it also supports renewable energy solutions that help homeowners generate their own electricity and reduce reliance on fossil fuels.

✅ Solar Panels – Solar power is an excellent way for homes to generate free electricity. ECO4 funds the installation of solar photovoltaic (PV) panels, which convert sunlight into energy, reducing electricity bills by up to 70%. This is a particularly beneficial upgrade for households looking to cut long-term costs and improve sustainability.
✅ Solar Batteries – One of the challenges with solar panels is that they only generate power during the day. ECO4 covers solar battery storage, allowing homes to store excess energy for use at night or during low-sunlight hours, increasing self-sufficiency and cost savings.

By integrating renewable energy solutions, ECO4 ensures that South Wales homeowners can reduce their energy bills and their carbon footprint, contributing to a cleaner future.

Smart Heating Controls & Ventilation Improvements

Smart technology and proper ventilation play a crucial role in optimising home energy use and preventing issues like damp and mould, which are common in older South Wales properties.

✅ Smart Thermostats & Heating Controls – Modern smart thermostats allow homeowners to regulate heating more efficiently, adjusting temperature settings based on daily routines. This prevents unnecessary energy use, cutting heating costs while keeping homes comfortable and warm.
✅ Ventilation Upgrades – Poor ventilation can lead to moisture build-up, dampness, and mould, affecting both home conditions and health. ECO4 provides funding for ventilation improvements, ensuring better air circulation and humidity control, particularly in older homes prone to damp issues.

By combining smart heating controls with improved ventilation, homes in South Wales can achieve greater energy efficiency while maintaining healthy indoor air quality.

How Do These Measures Benefit You?

By funding insulation, heating upgrades, renewable energy, and ventilation improvements, ECO4 ensures:

✔ Lower energy bills – Reducing heat loss and improving heating efficiency means less energy wasted and lower costs.
✔ A more comfortable home – Insulation and efficient heating keep homes warmer in winter and cooler in summer.
✔ A reduced carbon footprint – Cutting energy use helps combat climate change.
