🏠 Government-Backed Window Replacement in the UK (2025 Guide)

Want to lower energy bills, cut carbon emissions, and stay warm year-round?
You could be eligible for government support to replace your old windows — and save thousands in the process.

In this 2025 guide, we’ll explain:

✅ Why upgrading your windows matters
✅ What financial support is available
✅ Who qualifies (even if you don’t claim benefits)
✅ How to apply in your local area
✅ Real examples and current grant figures

💡 Why Replace Your Windows in 2025?

A surprising 80 million windows in UK homes are outdated and inefficient. According to the Glass & Glazing Federation (GGF):

• 🏚 Older double-glazed windows lose up to 44% more heat than modern equivalents
• 💸 Upgrading to energy-efficient glazing can save £395/year on energy bills
• 🌍 Homes contribute to 24% of UK carbon emissions — better glazing helps cut that fast

“Upgrading windows is one of the simplest, most cost-effective ways to boost your home’s energy rating and lower bills.”
— British Glass report (2024)
