Why 2025 Heatwaves Are a Wake-Up Call for UK Homes
The Met Office has confirmed that Summer 2025 is the hottest on record, with average temperatures reaching 16.13°C. Heatwaves are no longer “once in a decade” events experts at the World Weather Attribution group warn that days above 32°C are now 100 times more likely than before the industrial era.
For millions of households, this isn’t just climate science — it’s a daily struggle. From Manchester terraces to Cornwall cottages, UK homes are built to trap heat in winter, not release it in summer. That means:
- Sleepless nights in overheated bedrooms
- Higher electricity bills from fans & portable AC units
- Serious health risks for children, elderly, and vulnerable residents
But here’s the good news: with the right upgrades and ECO4 grants from Reliant Energy Solutions, your home doesn’t have to feel like a greenhouse. Instead, it can become a climate-resilient, energy-efficient sanctuary all year round.
The Cost of Cooling Homes the Wrong Way
When heatwaves strike, many people turn to fans or portable air conditioning units. While these provide short-term relief, they come with major downsides:
- Soaring energy bills — cooling appliances use huge amounts of electricity
- Higher carbon emissions — worsening climate change further
- No long-term benefit — homes continue to trap and store heat
This cycle of “reactive cooling” is unsustainable. The smarter, long-term solution is to stop heat entering in the first place.
Loft & Wall Insulation Grants: Your First Line of Defence
Most people think of insulation as “keeping warm in winter.” But it works both ways insulation also keeps your home cool in summer by slowing heat transfer.
- Loft Insulation – Acts like a thermal shield, stopping hot air from radiating into upstairs bedrooms.
- Cavity Wall Insulation – Prevents heat stored in external walls from leaking indoors.
- Solid Wall Insulation – A must for older homes, like Victorian terraces in Manchester or stone cottages in Cornwall, which tend to absorb and hold heat.
Through the ECO4 scheme, many households qualify for free insulation upgrades. This not only keeps your home cooler in summer but also slashes winter heating bills — a true year-round benefit.
Air Source Heat Pumps: One Upgrade, Two Solutions
For those seeking ultimate comfort, Air Source Heat Pumps (ASHPs) are the modern answer.
- In winter, they provide efficient heating
- In summer, they switch to cooling mode — working like an air conditioner but far more efficiently
Unlike old-fashioned AC units, heat pumps transfer heat instead of creating it, making them:
- Cheaper to run
- Lower in carbon emissions
- More reliable year-round
With ECO4 and the Boiler Upgrade Scheme (BUS), homeowners can receive grants up to £7,500 towards installation. This removes the biggest barrier: the high upfront cost.
ECO4 Grants in 2025: What’s Covered?
The UK government recognises that our housing stock is outdated and poorly prepared for climate extremes. That’s why ECO4 funding is available in 2025, covering:
- Loft, cavity wall, and roof insulation
- Renewable heating upgrades like heat pumps
- Entirely non-repayable grants (not loans)
- Available for homeowners, tenants, and landlords
Whether you live in a Birmingham semi-detached, a Glasgow flat, or a Bristol rental property, you may already qualify.

FAQ: Heatwaves, Grants & Energy Efficiency
Q1: Are ECO4 grants only for homeowners?
No. Tenants and landlords can also apply if the property meets the criteria.
Q2: How much can I save on bills with insulation?
Up to 25% annually — cutting both winter heating and summer cooling costs.
Q3: Can heat pumps really cool homes?
Yes. Modern ASHPs can reverse to extract heat, keeping homes comfortably cool in hot weather.
Q4: Do I need to repay the grant?
No. ECO4 and BUS are government-funded schemes with no repayment required.
Q5: How long does the installation take?
Most insulation or heat pump installs are completed in just a few days.
