About Us

Company Profile

Founded in 2008, Dec Associates was created with a simple goal: to make energy compliance straightforward for public authorities and commercial organisations. Our mission is to provide practical, reliable energy solutions that support a more sustainable and efficient future.
Our team is led by Nick, an experienced assessor and one of the first to achieve the ABBE Diploma in Display Energy Certificates. We are proudly accredited with ECMK and CIBSE, and our expertise covers a full range of services, including Display Energy Certificates (DECs), Energy Management Systems (ISO 50001), and ESOS compliance.
Clients choose us for our tailored approach, meticulous attention to detail, and unwavering commitment to exceptional service. From proactive renewal reminders to expert energy guidance, we ensure you stay compliant, informed, and fully supported at every stage.
Based in Southampton, we work with clients across the whole of England—whether you manage a single site or an extensive building portfolio.
If you have any questions about energy compliance or certification, we’d be happy to help. You can reach us on 02380 982 472, email us at admin@DECAssociates.co.uk, or use the contact form provided. We offer no-obligation quotations and clear, friendly advice whenever you need it.
