FAQs

Have a query? Here are the most frequently asked questions:
WHAT IS SAP CALCULATIONS?
SAP stands for Standard Assessment Procedure. It is the government approved methodology for the energy rating calculation of dwellings.
WHEN DO I NEED A SAP REPORT?
You will need SAP calculations if you are building a new house. You may also require a SAP calculation for any type of conversion or extension.
WHO DOES THE SAP & EPC REPORT
The SAP & EPC calculations are carried out by our team of qualified and accredited professionals. We are qualified as “OC DEA” consultants, which means On Construction Domestic Energy Assessors.
WHAT DOES A NEW BUILD EPC&SAP INVOLVE?
We will use evidence related to the proposed dwellings fabric, heating system, controls, lighting, glazing, wall insulation, loft insulation, etc. Then, we use the latest Full SAP technology that takes all these parameters into consideration in order to produce the EPC Energy Rating and Compliance Reports.
HOW LONG TILL I GET MY EPC & SAP REPORTS
The calculations of an average 3-bedroom semi take about a day, as long as we have all the information we need.
HOW LONG IS MY NEW BUILD EPC VALID FOR?
An EPC is valid for 10 years, unless the owner change the fabric and services to the building, i.e. build an extension or change the heating system.
WHAT ARE THE DOCUMENTS I NEED TO HAVE?
Usually, we ask for architect’s drawings. After you order your new Build EPC and SAP online, we will email you a small checklist of the information we need from you in order to carry out the SAP & EPC assessment. We will help you through the process so it is simple and quick.
WILL YOU NEED TO VISIT MY NEW BUILD PROPERTY?
We work from architects’ drawings only. There is no requirement to visit the actual property.
A Guide to SAP Calculations and New Build EPC Requirements
SAP Calculations and New Build EPCs are two important aspects when it comes to assessing the energy efficiency of a new dwelling. A SAP Calculation is used to estimate the energy performance of a new build in terms of its heating, cooling, and ventilation requirements. On the other hand, an Energy Performance Certificate (EPC) is part of the SAP calculations and it is required for new build properties application for Building Control approval as well as part of a sale or rental process. It provides an indication of how energy efficient a property is and gives potential buyers or tenants an idea of what their energy bills might be.
What Factors Are Used in SAP Calculations and How Do They Impact Your Building’s Energy Efficiency?
SAP as a methodology is used to determine the energy performance of a building and to identify areas where improvements can be made. SAP stands for Standard Assessment Procedure, and it is essentially the latest regulations related to energy efficiency and the protection of the environment, incorporated into a assessment platform. The system produces computer generated compliance reports that must be followed in order to ensure that the building meets the government targets. Improving the energy efficiency of a new build is possible by taking various steps such as re-specifying the fabric of walls, ceiling, and floors; re-specifying windows and doors lower u-values and implementing renewable energy solutions.
How to Improve the EPC Rating of a New Build Home
Improving the Energy Performance Certificate (EPC) rating of a new build home is becoming increasingly important, both for meeting the government’s latest regulations and to save money in energy bills the long term. There are various steps that can be taken to improve the EPC rating of a home, such as using energy efficient blocks and insulating materials, reducing open spaces, reducing glazed areas, improving efficiency of windows and doors, increasing insulation levels, improving airtightness, considering a combination of heat pumps and photovoltaic panels.
What is TFEE – Target Fabric Energy Efficiency of New Build Homes
In simple words, the Target Fabric Energy Efficiency (TFEE) of a new build home is an important measure used to assess the energy efficiency of the chosen fabric of a new build. It is calculated by taking into account the proposed wall, ceiling and floor structures, the proposed insulation, windows and doors as well as the specified air tightness and ventilation. By understanding TFEE of a new home at design stage, architects and homeowners can make informed decisions about what building solutions to use at the “as design stage”, and how to modify these in order meet the latest building regulations.
TFEE must be considered for computer simulation and optimisation at design stage. Once a house is finished (as build) it becomes very complicated, if not impossible, to change TFEE value. The TFEE target for new homes has been set by the government and it is important that all new build homes in England meet this standard in order to ensure compliance. The standards vary between England, Wales, Scotland and Northern Ireland, with 2022 Building Regulations already in force in England, while Northern Ireland remains to 2009 building standards.
