Why QPS Diagnostics

QPS Diagnostics provides accredited non-domestic energy assessments for commercial, retail and healthcare properties. Founded by Mike Au-yeung, a fully qualified Non-Domestic Energy Assessor accredited through Elmhurst Energy (ABBE Diploma, Levels 3 & 4), QPS Diagnostics makes EPC compliance straightforward for landlords, agents, developers, and facilities managers.

We carry out every assessment to current regulatory standards, with clear, accurate reporting and no unnecessary delays—because an out-of-date or missing EPC can hold up a sale, a letting, or a compliance deadline.
