Project Overview
Carbon3 partnered with one of the UK’s biggest housebuilders to deliver renewable energy systems at a landmark development in Tooting that’s transforming the site into over 800 new homes, green spaces, and community facilities.
Our team designed and installed 352.89 kWp of solar PV capacity across 11 apartment blocks and 32 individual homes, forming a central part of the project’s sustainability strategy. These installations complement the site’s 42 electric vehicle charging points and 450 cycling spaces, helping residents embrace cleaner travel and lower-carbon living.
Supporting Part L and Beyond
The development has been designed to meet the latest Part L 2022 Building Regulations, which require a 31% reduction in carbon emissions compared to previous standards. Carbon3’s solar PV systems play an important role in helping the client achieve these targets and align with London Plan Policy SI2, which promotes on-site renewable generation and energy efficiency.
By generating over 300,000 kWh of clean electricity each year, enough to power around 100 London apartments, the systems are expected to save approximately 76 tonnes of CO₂ annually, supporting Barratt’s broader net zero ambitions and improving EPC performance across the site.
Design-Led Delivery
From the outset, the project demanded close collaboration between Carbon3’s design engineers, the client’s sustainability consultants, and the wider construction team. Using advanced shading analysis, load modelling, and structural assessments, our engineers created bespoke PV designs for each roof type to maximise generation without compromising the architectural integrity of the buildings.
Every stage of the process, from feasibility and layout design through installation, commissioning and handover, was managed by Carbon3’s in-house teams, ensuring consistency, safety, and full compliance with warranty and M&E standards.
Outcome and Impact
The completed systems provide reliable, low-cost energy for both individual homes and communal areas, reducing operational costs and supporting sustainable living. Together with EV charging and cycling infrastructure, the renewable installations reflect the client’s commitment to building future-ready communities that meet both environmental and social needs.
The development stands as a strong example of how considered design and expert delivery can help large-scale developments meet the UK’s evolving sustainability legislation. The project turns ambitious carbon targets into practical, high-performing energy solutions.
