After the survey and EPC rating check, we submit your application for grant approval. Once approved, this official confirmation gives you full access to the funded upgrades under ECO4. This approval also means zero upfront costs for you, so you can proceed confidently.
Our qualified, Gas Safe registered professionals will install the approved upgrades according to ECO4 standards. This includes insulation, heating systems, windows, or any other ECO4-eligible improvements. All installations prioritize your comfort and safety.

Shadat with a brand new Worcester Bosch, and I couldn’t be happier! He was absolutely incredible from start to finish. Hard-working, fast, professional, and genuinely polite, Shadat made the whole process smooth and stress-free.
