What is a SAP calculation?

A SAP (Standard Assessment Procedure) calculation is the government-approved method for assessing the energy performance of residential buildings in the UK. It’s required for newly constructed homes, conversions such as building from existing structure, barn conversions, splitting existing dwelling into 2 and vice versa as well as major extensions. 

Always check with building control what your requirements are.
 
SAP calculations determine how much energy will be used for heating, lighting, ventilation, and hot water, as well as how much CO2 will be emitted. By assessing these factors, we can ensure that your building meets energy efficiency standards, saving future occupants money on their energy bills and reducing the environmental impact.

Why do you need an EPC?

An Energy Performance Certificate (EPC) is a legal requirement when selling, renting, or constructing a new home. It provides a rating from A (most efficient) to G (least efficient), offering future homeowners or tenants an insight into the building's energy usage, emissions and fabric performance and its impact on running costs. EPCs are issued only after a SAP completed and building control signed off, ensuring that your building meets energy efficiency standards. Our team provides a seamless process from SAP calculation to EPC issuance, ensuring your property is energy-efficient and compliant with all regulations.
