Whatever your needs, whether it be TGD Part L Compliance, TGD Part F Compliance, TGD Part E Compliance, Overheating Calculations and Daylight Analysis, our compliance services ensure your project meets the latest energy performance standards from start to finish.

We provide energy consultancy, airtightness testing, and BER certification to ensure your project meets thermal performance and carbon targets under Part L.

We carry out Independent Ventilation Verification and system performance checks to confirm that mechanical ventilation systems are installed and operating to required standards.

Using dynamic simulation or CIBSE TM59 methodology, we assess the risk of overheating in dwellings—an increasingly important requirement under NZEB and planning guidelines.

We provide daylight modelling to demonstrate compliance with planning or regulatory standards, ensuring that internal spaces receive sufficient natural light.

All testing and analysis includes clear, regulation-ready documentation for submission to Building Control Authorities or your Assigned Certifier.
