SAP & EPC

The Standard Assessment Procedure (SAP) is the UK Government’s methodology for assessing and comparing the energy and environmental performance of residential buildings. It is a key requirement for demonstrating compliance with Part L of the Building Regulations and forms the basis of the Energy Performance Certificate (EPC).

SBEM Calculations

The Simplified Building Energy Model (SBEM) is the UK Government’s approved methodology for assessing the energy performance of non-domestic buildings. It is used to demonstrate compliance with Part L of the Building Regulations and to produce Energy Performance Certificates (EPCs) for commercial properties.

Energy Statements

An Energy Statement is a key document submitted as part of the planning application process to demonstrate how a proposed development will meet local and national energy and carbon reduction policies. It sets out a clear strategy for reducing energy demand, improving efficiency, and minimising carbon emissions.

Energy Statements are typically required by local planning authorities, particularly for major developments, and are assessed alongside other planning documents.

Part O Overheating

With rising summer temperatures and the tightening of energy efficiency standards, managing solar gain is no longer just about comfort—it’s a legal requirement. Part O of the Building Regulations ensures that new residential buildings are designed to limit unwanted solar gain and provide adequate means to remove excess heat.
Our expert consultancy provides comprehensive Overheating Risk Assessments to ensure your project meets these stringent standards without compromising on design or performance.

Part G Water Usage

Part G of the Building Regulations in England and Wales sets standards covering water use and sanitation efficiency in new homes.

Part E Acoustic Testing

Privacy and comfort start with what you don’t hear. Part E of the Building Regulations sets out the requirements for sound insulation in residential buildings, ensuring that neighbors, both above and below as well as to the sides, aren’t disturbed by the day-to-day noise of modern living.

Whether it’s a new build or a conversion project, our Acoustic Testing service ensures your development meets the legal requirements for airborne and impact sound insulation.

Air Tightness Testing

An airtight building is the foundation of high-performance construction. Air Tightness Testing (also known as Air Permeability or Pressure Testing) is a critical requirement under Part L of the Building Regulations. It measures the extent to which air is “leaking” through the building envelope via gaps, cracks, and poorly sealed joints.
