Here’s something worth your attention:
As of June 2025, the UK government has taken a bold step: new homes in England will soon be required by law to include rooftop solar panels. This is part of a broader effort to reduce energy costs, ensure long-term energy security, and decarbonize residential buildings.
If you’re in the solar or battery storage space, this signals more than just compliance — it’s the start of a market shift. Let’s break it down.
What’s changing?
- All new homes must install solar panels covering at least 40% of the ground floor area;
- If that’s not feasible, a “reasonable amount” must still be installed — no full exemptions allowed;
- Low-carbon heating (heat pumps or heat networks) is also required;
- Enhanced insulation, airtightness, and EV charger readiness will become standard features.
When will it take effect?
- Fall 2025: Final version of the policy released
- December 2026: Regulations officially take effect
- Mid-2028: Full transition period ends
Why does this matter?
Solar won’t just be a nice-to-have anymore — it’ll be part of the core design of every new home in England. That’s a massive shift in mindset. And it has ripple effects across:
- Homebuilders and architects
- Solar panel and inverter suppliers
- Energy storage and battery system integrators
- Mortgage and financing institutions
How much will it save homeowners?
Under current energy prices, a standard 3.5kW south-facing solar setup could save families £530 per year on electricity bills. When paired with a heat pump and battery storage, total savings rise to over £1,300 annually. Over 25 years, that’s more than £46,000 in avoided energy costs — not to mention added property value and sustainability benefits.
What are the challenges?
The policy isn’t without hurdles. Developers will shoulder the upfront cost of solar, which adds around £3,000–£4,000 per home. Grid upgrades and connection delays are a bigger concern. Some projects in the UK are already facing multi-year delays due to outdated grid infrastructure.
Small developers warn this could make affordable housing less viable unless infrastructure costs are fairly shared across sectors.
What’s next?
Whether you’re in construction, renewables, or the battery industry — this policy shift is your signal. The UK is setting the tone for how homes will be built in the post-crisis energy landscape.
As solar becomes mandatory, storage will become indispensable. For clean, uninterrupted energy — especially when the sun isn’t shining — batteries complete the equation.
