SAP Calculations
Standard Assessment Procedure (SAP) calculations measure energy efficiency and carbon emissions for new builds, extensions, and conversions. Our accredited assessors ensure compliance with Part L building regulations using Elmhurst-certified software. We provide design-stage and as-built assessments with 48-hour turnaround, supporting planning applications and EPC generation across residential and commercial projects.
TM44 Inspection
TM44 inspections evaluate air conditioning system efficiency in commercial properties. Our certified inspectors assess energy performance, identify improvements, and produce reports meeting regulatory requirements. Regular TM44 assessments help businesses reduce energy costs and comply with UK building regulations through optimised HVAC performance.
Biodiversity Net Gain
Biodiversity Net Gain (BNG) assessments quantify ecological value before and after development. Our ecologists conduct preliminary appraisals, habitat mapping, and mitigation planning to achieve mandatory 10% biodiversity uplifts. We support planning applications with Defra-compliant calculations and long-term habitat management strategies for sustainable development.
Air Tightness Testing
Air tightness testing measures uncontrolled air leakage in new and existing buildings. Using calibrated fan pressurisation equipment, we identify heat loss points and ensure compliance with Approved Document L. Our UKAS-accredited engineers provide testing for SAP calculations, building control sign-off, and energy performance optimisation across residential and commercial developments.
Acoustic Design
Acoustic design services ensure compliance with building regulations for sound insulation. We conduct pre-construction testing, party wall evaluations, and environmental noise surveys for residential, commercial, and industrial projects. Our solutions address workplace noise, planning requirements, and vibration control to meet Part E standards and occupant comfort needs.

Report
Overall a very good experience for my first time ordering SAP report. Very affordable (half the price of any other company I found). Big thanks to Jamie for his help and support. Really pleased with the end result. I Would highly recommend.
