Sustineo

Your Partners in Energy Compliance and Efficiency

At Sustineo, we believe that navigating energy regulations shouldn't be a headache. Whether you are a commercial landlord, a property developer, or a homeowner, we provide the technical expertise you need to stay compliant and improve your building's performance.

Based in Milton Keynes with a robust network of accredited assessors across England and Wales, we’ve been a trusted name in the industry since 2008. As a firm regulated by the Royal Institution of Chartered Surveyors (RICS), we hold ourselves to the highest professional standards, ensuring every assessment is accurate, timely, and cost-effective.

Why Property Professionals Choose Sustineo

We know that timing is everything in property transactions. That’s why we’ve built our reputation on a "no fuss" approach that prioritises your deadlines without compromising on quality.

Specialist Commercial & MEES Advice

The Minimum Energy Efficiency Standards (MEES) have changed the landscape for landlords. We don't just "tick a box"; we provide tailored advice to help you achieve an E rating or better, or guide you through the process of seeking exemptions where applicable.

The Sustineo Difference: We will always notify you if a property is not MEES compliant before we lodge the EPC. This gives you the vital opportunity to take action and ensure compliance before a letting is completed.

From New Builds to Public Buildings

Our expertise spans the entire lifecycle of a property, from the drawing board to the public display:

• New Developments: We provide SBEM and SAP calculations at the design stage to ensure your project meets current Building Regulations.
• Public Sector: We are accredited to provide Display Energy Certificates (DECs) for public buildings over 250m², helping occupiers track and improve actual energy usage.
• Technical Documentation: From precise U-Value calculations to Land Registry compliant floor plans, we handle the technical details so you can focus on your project.

Led by Chartered Expertise

Our Managing Director, John Hearnshaw, is a Chartered Surveyor with extensive qualifications across domestic, non-domestic, and retrofit assessment. Under his leadership, our team ensures that whether the job is a single studio flat or a complex industrial unit, it receives the same level of professional scrutiny and care.
