As temperatures rise across the UK, many households are searching for ways to keep cool indoors without relying heavily on expensive fans or air conditioning. While insulation is often associated with keeping warm in the winter, it plays just as important a role during summer. In fact, upgrading your home insulation now through government-backed schemes like ECO4 and the Great British Insulation Scheme (GBIS) can improve comfort all year round – while cutting your energy bills.
Why Insulation Matters in Summer
Good insulation doesn’t just trap heat in during colder months – it also keeps excessive heat out during warmer weather. A properly insulated home will stay cooler for longer, reducing the need for cooling devices and making it easier to maintain a pleasant indoor temperature naturally.
Meet Real People Benefiting from Insulation
Case 1: A family in Birmingham battling high temperatures
The Speights live in a 1930s semi-detached home with poor insulation. Before the upgrades, their upstairs bedrooms were unbearable on hot days. Through ECO4, they received loft and cavity wall insulation, reducing summer indoor temperatures by several degrees. “We sleep better, and our energy bills are lower. It’s been a life-changer,” says Mrs. Speight.
Case 2: A pensioner in Leeds struggling with bills
Mr. Clarke, 72, was spending over £200 a month on energy just to stay warm in winter and cool in summer. Under GBIS, he had underfloor insulation and a smart thermostat installed. Now, his home retains a more stable temperature. “I don’t need to run fans all day, and I’m saving around £400 a year,” he says.
Case 3: A young couple in Cornwall planning a family
Lisa and Tom recently bought an older property with an EPC rating of E. They qualified for external wall insulation and solar panels under ECO4. Their home now stays cooler in summer, and they’re generating their own energy. “We feel future-proofed – and ready for winter too.”
What Are ECO4 and GBIS?
ECO4 (Energy Company Obligation Phase 4)and GBIS (Great British Insulation Scheme) are UK government initiatives designed to help households improve energy efficiency at little to no cost. These schemes are focused on supporting low-income and vulnerable households or homes with low EPC ratings.
- ECO4 offers multi-measure upgrades, including insulation, heating systems, solar panels, and smart controls.
- GBIS typically covers single insulation measures, but was updated in 2025 to allow two insulation types per property.
Both schemes aim to reduce fuel poverty, lower carbon emissions, and make UK homes more energy efficient.
Why Summer Is the Best Time for Home Improvements
The summer season is perfect for insulation and other home upgrades:
- Dry weather = fewer delays and faster installations
- Installers have better availability, before the autumn rush
- Start saving immediately on both cooling and upcoming heating costs
- Beat the funding deadlines: both ECO4 and GBIS end in March 2026
By taking action now, you not only avoid last-minute winter installations but also make your home more liveable during hot spells.
