Eco Homes in London: The 2025 Guide for Sustainable Living & Smart Investment
London is racing towards a greener future — and nowhere is that more visible than in the rise of eco homes across the capital. From energy-efficient new builds to intelligently retrofitted heritage properties, London’s eco homes offer a powerful blend of sustainability, comfort and long-term value.
This 2025 guide breaks down what eco homes are, why they matter in London, where to find them, and how to evaluate them with confidence.
1. What Exactly Is an Eco Home?
An eco home in London is defined by high performance, low environmental impact and sustainable design. Key features include:
EPC rating of A or B
High insulation and airtightness
Triple-glazed windows
Low-carbon heating (heat pumps, district heating)
Renewable energy integration (often solar)
Sustainable materials
Low-VOC paints and healthy indoor air systems
Water-saving technology
Smart-home energy monitoring
In London, eco homes are increasingly becoming the default in new developments.
According to national energy data for 2024, 87% of new homes in England achieved an EPC A or B, with London ranking among the highest for efficiency.
