End-to-End Retrofit Services supporting social housing towards Net Zero
At ECO Surv, we are passionate about carbon reduction and sustainability and we believe in the power of retrofit to transform homes, cut carbon emissions, and make energy efficiency accessible for all.
Since 2015, our PAS retrofit platform has facilitated over 500,000 surveys across 400,000+ homes, driving an annual reduction of 510 million kilograms of CO2 and saving households an average of £698 per year on energy bills (*based on new heating and insulation upgrades).
But the impact goes beyond numbers. Retrofit plays a crucial role in tackling fuel poverty, ensuring that the most vulnerable members of society can enjoy warmer, healthier homes. With the 2030 EPC C rating deadline fast approaching, housing providers and housing associations face increasing pressure to improve their stock and support tenants to save on their energy bills. But the good news is that funding streams, like WH:SHF Wave 3, are available to support this transition.
ECO Surv offers a flexible approach to help you evaluate, plan, and deliver retrofits – whether you’re managing five properties or 5,000. From full turnkey solutions powered by our award-winning software to tailored support at key project stages, we’re here to ensure your journey to Net Zero is smooth, compliant, and cost-effective.
