The landscape of residential development is changing rapidly. With the UK government tightening regulations under Part L and moving toward the Future Homes Standard, developers are under increasing pressure to reduce carbon emissions and integrate on-site renewable technologies. At the same time, new legislation around electric vehicle (EV) infrastructure is making charging points a core requirement rather than an optional extra.
For developers like our client, these shifts present both a challenge and an opportunity.
At their development in Dartford, comprising seven apartment blocks, our client saw the potential to utilise unused flat roofs and car parking areas by installing renewable technologies. The aim of this project was to futureproof against government compliance and increase buyer appeal.
The project:
Carbon3 was appointed to design and deliver an energy solution that aligned with both current and anticipated regulation while adding tangible value for homeowners.
Scope of works:
- 38 EV charge points installed across resident and visitor parking areas
- 80.77 kW of solar PV installed on seven flat roof blocks, all previously unused
- Fully integrated with the build programme
- Completed in line with site handovers and resident move-ins
Our in-house engineers worked collaboratively with the client’s construction and site teams to coordinate installation timelines, electrical connections, and compliance documentation to ensure seamless delivery without disrupting the wider programme.
A proactive response to changing regulations
By 2025, the Future Homes Standard will mandate significantly higher energy performance in new builds, with on-site renewables like solar PV expected to play a central role. Similarly, EV infrastructure regulations introduced in 2022 require all new residential developments with parking to include charge points.
Our client anticipates these shifts, and understands the importance of preparing for the next wave of building standards and buyer expectations.
The homebuyer impact
The benefits of this infrastructure go beyond compliance.
For buyers, the integration of solar PV systems means lower electricity bills and improved energy performance ratings (EPC), which can influence mortgage rates and long-term affordability. As energy prices remain volatile, rooftop solar offers a buffer against external market pressures, giving homeowners greater control over their usage and costs.
Meanwhile, the 38 EV charge points make the development truly fit for the future. With the phase-out of petrol and diesel cars fast approaching, having on-site charging is essential. Residents and visitors alike can now charge their vehicles safely and conveniently at home, avoiding the limitations of public infrastructure.
Combined, these technologies make this development a highly attractive proposition for eco-conscious buyers and renters looking for modern, energy-efficient living in Greater London.
A model for low-carbon development
Our client’s approach sets a powerful example for other developers navigating market demand and regulatory compliance. By partnering with Carbon3, they’ve delivered:
- Long-term asset value through efficient use of unused roof space
- A competitive edge in a high-demand market
- Strong ESG credentials that align with investor expectations and public policy
- A complete, turnkey solution covering design, installation, and long-term support
Our remote monitoring and post-handover maintenance services ensure that the systems installed continue to perform long after keys are handed over. We track output in real time and flag any drop in performance to avoid expensive faults or resident complaints, while eliminating the need for intrusive site visits.
What this means for other developers
This development highlights the value of acting early to incorporate energy infrastructure into the build process, not as a retrofit afterthought. Costs of retrofitting renewables far outweigh the cost of installing at build. Whether you’re working with houses or apartments, new builds or mixed-use schemes, solar and EV charging are fast becoming essential parts of development strategy.
At Carbon3, we help developers stay ahead of the curve with integrated, cost-effective energy systems that meet today’s needs and tomorrow’s standards. Our deep experience in multi-phase construction environments means we understand your programme, your risks, and your commercial priorities.
We work with developers of all sizes to deliver Part L–compliant, ESG-aligned energy strategies across new build housing. Whether you’re integrating solar, battery storage, or EV infrastructure, Carbon3 offers a full-service solution, designed to fit your timeline and budget. Contact us today to find out more.
