SAP Calcs / SAP Calculations / Sap Ratings / SAP Assessments are a Government defined process in accordance with Part L Building Control Regulation Compliance of Domestic Property

SAP calculations are the Government's Standard Assessment Procedure for Energy Ratings.

Since 6th April 2006, Part L1 has required SAP Calculations to be carried out on every new dwelling or conversion in the UK.

Whether you're an architect, self builder, developer or homeowner, we can help. We deal with singular plots and alterations / extensions right up to large residential sites.

At E2 Consultants we pride ourselves on being able to provide all of the Part L services. As well as SAP Calculations we also provide On Construction EPCs, SBEM calculations, Air Tightness / Pressure Testing , Sound / Acoustic Testing, Commercial EPCs and Code for Sustainable Homes (C4SH) Assessments / BREEAM Assessments with consultancy.

As part of our service we advise our clients as to how they can best achieve compliance in the most cost-effective manner, for this reason, all of our SAP Calculations are site-specific. Alterations are free of charge and our SAP Assessors will also liaise with Building Control Officers on your behalf.

On Construction Energy Performance Certificates (EPCs)

From 6 April 2008, all homes built and physically complete on or after this date will need to have an Energy Performance Certificate (EPC) provided "on construction".

E2 Consultants offer these On Construction Energy Performance Certificates (EPCs) produced using the SAP Methodology and are undertaken by one of our On Construction Domestic Energy Assessors (OCDEAs). The certificates are needed if a property is to be sold or let, they can also be requested by Building Control.

Your initial SAP Assessor may not be qualified to produce On Construction EPCs but E2 Consultants are able to produce your On Construction Energy Performance Certificates (EPCs) even if SAP Calculations have not already been carried out.

It is the responsibility of the builder to provide any On Construction EPCs when a home is constructed and physically completed from 6 April 2008. This will also apply if a building is converted into fewer or more units (material change of use) and changes are made to the heating, hot water provision or air conditioning/ventilation services.

If you are selling a home before it has been built, you will need to provide information about energy efficiency in a Predicted Energy Assessment (PEA). This is simply the predicted SAP Calculation and Environmental Impact (CO2) rating from the SAP Calculations you do at the design stage to check whether you will meet energy-saving targets. For a quote or for general advice regarding SAP Calculations and On Construction EPCs please call one of our regional offices on 0800 043 8100
