How we help you
EPCs and SAP assessments
At Expert Energy Consultancy Ltd, we specialise in providing SAP calculations and Energy Performance Certificates (EPCs) for new builds, conversions, and extensions across the UK. Our team of accredited SAP assessors ensures that your project complies with building regulations while optimising energy efficiency from day one. Whether you're a homeowner, architect, or developer, we offer tailored advice and fast turnaround times to meet your needs. We cover everything from design-stage SAP calculations to as-built assessments.
Extension Calcuations
Expert Energy Consultancy Ltd provides specialist extension calculations to ensure your new space complies with Part L Building Regulations. Whether installing large glazed doors or using advanced materials, our accurate assessments help you meet energy efficiency requirements while building smart and sustainably. We offer tailored guidance on compensatory upgrades and supply all documents required for Building Control submission.
Part O Overheating Calculations
In the face of rising temperatures, Part O (England) Section 3 (Scotland) Overheating of the Building Regulations was introduced to combat overheating risks in residential buildings. At Expert Energy Consultancy Ltd in Sheffield, we provide detailed overheating calculations with particular attention to vulnerable occupancies to ensure thermal comfort and safety during periods of hotter weather.
Our team performs comprehensive assessments of solar gains and ventilation strategies, offering solutions like solar shading, openable windows, and dynamic thermal modelling when needed. Whether you’re working on a new build or conversion, we ensure your space remains cool and energy-efficient.
PSI Value Calculations
Psi values, also known as Ψ values, quantify heat loss where building elements meet, such as walls, floors, and roofs. These junctions are non-repeating thermal bridges, and the wireframe of the house can significantly impact your SAP score and overall energy efficiency. Psi value calculations are required for new build homes to demonstrate compliance with energy efficiency standards under Building Regulations. A key advantage is that calculated Psi values can be reused on subsequent sites that use the same construction details.
Water Usage Calculations For Part G compliance
Expert Energy Consultancy Ltd specialises in accurate, efficient water usage calculations for new dwellings and conversions across the UK. Part G of the Building Regulations requires that water use is limited to 125 litres (or 110 litres under local policy) per person, per day. We assess your fixtures, fittings, and appliances to ensure compliance before and after construction.
