🔍 Window Grants – Guide to Government Grants for Windows
📢 Subsidy for more money | Insulation | Warmth | Low threshold
Tired of chilly draughts in winter and stifling heat in summer? Old windows driving your energy bills through the roof? Here’s some good news—you might qualify for UK government-backed support to upgrade your windows and improve home energy efficiency. Through the ECO4 and ECO-Flex schemes, you can make your home warmer, quieter, and more cost-efficient—with little to no out-of-pocket cost.
🔍 What Are ECO4 and ECO-Flex?
âś… ECO4 (Energy Company Obligation Phase 4)
ECO4 is the fourth phase of the UK government's long-running energy efficiency scheme (2022–2026). It requires major energy suppliers to fund energy-saving home improvements for households that are low-income or have high energy usage. The aim is to reduce carbon emissions, lower energy costs, and combat fuel poverty.
Key features include:
- Available to homeowners and private renters
- Targets homes with poor energy ratings (EPC rating of E, F, or G)
- Covers upgrades like insulation, boilers, and window replacements
âś… ECO-Flex (Flexible Eligibility Criteria)
ECO-Flex is an extension of ECO4 that allows more people to benefit—even if they don’t receive government welfare benefits. Local councils can define flexible eligibility criteria, such as:
- Low income
- High energy usage
- Households with elderly residents, children, or health conditions
That means many people who wouldn’t traditionally qualify can still access help through their local authority.
🏡 What Upgrades Are Covered?
Here are the home improvements that the schemes typically fund:
| Upgrade Type | Covered? |
|---|---|
| Replacing single-glazed windows with double or triple glazing | âś… Yes |
| Installing insulation in walls, lofts, or floors | âś… Yes |
| Replacing or installing high-efficiency boilers or heat pumps | âś… Yes |
| Adding smart thermostats or heating control systems | âś… Yes |
| Sealing doors and windows, improving ventilation | âś… Yes |
🔸Why replace windows in summer or autumn? These seasons offer mild weather—ideal for installation. New windows help keep your home cool in the summer, retain warmth in the winter, and reduce noise all year round.

🌟 Real Story: “Building a warm home”
Sarah, a mother of two from Leeds, was struggling with freezing rooms and high energy bills due to her home’s old single-glazed windows. “It felt like the cold was living with us,” she said. After applying through the ECO4 scheme, her home was upgraded with energy-efficient double-glazed windows—and it cost her next to nothing.
“The warmth was immediate,” she shared. “The house feels quieter, and our heating bill dropped by nearly £100 in just two months. We honestly couldn’t believe this was government-backed.”
