At Crowther Solutions Ltd, we provide accredited On-Construction Energy Performance Certificates (EPCs) for residential developments across the UK. With a track record of excellence since 2005, we understand that a New Build EPC is more than just a piece of paper—it is the final legal requirement for building sign-off, property sales, and rentals.
Unlike a standard domestic EPC used for older homes, a New Build EPC must be produced by an accredited On-Construction Domestic Energy Assessor (OCDEA) using the full SAP methodology. It is calculated based on precise construction data, architectural plans, and on-site testing rather than the simplified assumptions used for existing buildings.
We manage the entire energy compliance journey to ensure your project is "signed off" without delays:
Design Stage SAP: We perform initial SAP Calculations before work begins to ensure your design meets Part L targets for carbon emissions and fabric efficiency.
As-Built Calculations: Upon completion, we update the data to reflect the exact materials used and incorporate your Air Leakage Testing results.
Part L Photographic Evidence: In line with 2021/2022 regulations, we conduct the mandatory audit of Photographic Evidence required by Building Control for final EPC lodgement.
Final EPC Lodgement: We issue the final certificate and the BREL (Building Regulations England Part L) compliance report needed for legal completion.
Expertise Since 2005: We have navigated every major update to the UK Building Regulations for two decades, providing "Compliance Through Knowledge" on thousands of plots.
National Coverage: We provide a seamless, hassle-free service for developers, architects, and self-builders throughout the UK.
Chartered Oversight: Our founder is a Member of the Chartered Institute of Building (MCIOB), ensuring elite technical standards.
Upfront Advice: We don't just report failures; we provide the practical, cost-effective solutions needed to achieve a pass.
