Services
Air Testing
We conduct air leakage testing for residential and non-residential buildings to ensure compliance with Part L regulations. Our UKAS-accredited team identifies and addresses air permeability issues, reducing energy costs and improving building efficiency. Services include design-stage reviews, on-site inspections, and remedial guidance to achieve compliance.
Thermal Imaging
Thermal imaging surveys detect energy losses, insulation defects, and moisture issues in buildings. Our non-invasive technology identifies thermal bridges and air leakage paths, supporting BREEAM compliance and energy efficiency improvements for commercial and residential properties.
Acoustic Testing
We perform sound insulation testing to meet Building Regulations Part E requirements. Our services address noise issues in residential and commercial buildings, including cross-talk in offices and reverberation in schools, ensuring compliance with UK standards.
SBEM Calculations
SBEM calculations assess the energy performance of non-residential buildings. We provide detailed reports to demonstrate compliance with Part L2A regulations, supporting EPC generation and carbon footprint reduction strategies.
SAP Calculations
SAP calculations evaluate the energy efficiency of residential dwellings. Our reports ensure compliance with Part L1A regulations, supporting EPC production and compliance for new and converted properties.
