What is a Part L SAP Calculation?
Part L SAP Calculations (Standard Assessment Procedure) constitute a crucial element of the Building Regulations, applying to all newly built residential properties throughout the UK. Mandated since 1995, the need for a SAP Rating, as per Part L of the building regulations, has become a firmly established practice embraced by the majority of developers.
SAP Calculations serve three primary functions:
SAP calculations serve several key purposes:
-
They determine a SAP Rating, which quantifies the energy-related operational costs linked to a dwelling.
-
They offer evidence of compliance with Part L of the building regulations.
-
They enable the creation of an Energy Performance Certificate (EPC).
It's important to mention that SAP calculations might also be required for conversions or extensions, subject to slightly different regulations, and Scotland maintains its own specific requirements.
SAP Calculation Factors
-
SAP calculations play a crucial role in quantifying two essential factors: the Dwelling Emission Rate (DER) and the Dwelling Fabric Energy Efficiency (DFEE). These figures form the foundation for establishing:
-
A Target Emissions Rate (TER)
A Target Fabric Energy Efficiency (TFEE) rate
In England, it's imperative that the DER and DFEE values are lower than the TER and TFEE calculations. Conversely, in Wales and Scotland, the focus primarily lies on DER measurements. -
If you're considering selling or renting out your property, completing SAP calculations is essential for obtaining an Energy Performance Certificate (EPC), which is a legal requirement for all new builds.
-
Should your SAP calculation indicate that your dwelling emission rate doesn't meet compliance standards, there's no need to worry! Our assessors are available to offer practical advice and guidance on necessary adjustments to enhance your building's energy efficiency. This includes minimizing energy consumption, optimizing thermal elements, refining ventilation systems, meeting CO2 emissions targets, and integrating renewable technology components.
-
Addressing these areas can significantly improve your dwelling's energy profile, leading to reduced fuel costs and the acquisition of the coveted energy performance certificate.
How much are SAP Calculations?
-
SAP Calculations and assessments begin from just £99 per unit, varying depending on the complexity and size of the building, lead time only around three days.
-
Our pricing structure is tailored to the specific dimensions and intricacies of your dwelling. We believe in offering bespoke quotes on an individual basis to ensure you receive the most competitive pricing possible.

Our energy assessment prices include a comprehensive package, encompassing lodgement and registration fees, expert guidance on building regulations compliance, iterative improvements, and the issuance of all necessary supporting documentation.
Important information to help you plan for your SAP Assessment
-
SAP assessments play a pivotal role in comprehending your design. Ideally, we require accredited construction details and comprehensive, up-to-date drawings, preferably in electronic format.
-
Please note that we are unable to utilize photographs, rough sketches, or watercolors. You may be requested to furnish a fairly detailed specification of your construction plans. This enables us to gauge the level of development in your design, determine fixed aspects, flexible elements, and areas that remain uncertain. With this information, your assessor can provide guidance and assistance to fill in any gaps.
When are SAP Calculations for Conversions needed?
SAP Calculations for Conversions become necessary when a building undergoes a transformation from a non-domestic use to a domestic one, such as converting from a shop or office to a house, which is classified as a 'Material Change of Use' or a Change of Energy Status. These calculations evaluate the energy efficiency of the proposed alterations and offer recommendations for enhancements where required.
When considering changes in material use during a conversion, you may be examining aspects such as:
- Insulation materials for walls, floors, and roofs
- Window glazing types and frames
- Heating and hot water systems, including boilers and radiators
- Ventilation systems to ensure adequate airflow while maintaining energy efficiency
- Lighting fixtures and fittings, focusing on energy-efficient options like LED bulbs
- Renewable energy technologies like solar panels or heat pumps for sustainable energy generation.
✔️Transitioning a building from a non-residential or commercial property to residential use
✔️Adding an additional flat to the existing structure
✔️Increasing the number of dwellings within one building.
Transitioning to a new energy status may become necessary when an unheated area or building is being newly designated for heating. Additionally, changes in the usage of a building could lead to alterations in its energy status. We're here to assist you throughout this process, ensuring that you are well-informed and up-to-date on everything related to the modification of your energy status.
Should any issues arise during the delivery of your SAP Calculations, rest assured that our experienced team will address them efficiently. We provide peace of mind and swift solutions, enabling you to proceed smoothly with your plans.
Our process – how we ensure you meet the required standards
We recognize the significance of maintaining compliance with conversions, which is why we utilize SAP Calculations to verify if U-Values meet the standards outlined in all technical documents approved by the government. If these values fall short of expectations, we want to assure you that our team will provide guidance on the best course of action.
Moreover, we take extra measures to ensure that lighting and heating levels surpass the minimum requirements. If adjustments are necessary for compliance, rest assured that we will assist you every step of the way.
Simply download and complete our checklist, providing all the required information. We offer a fast and efficient turnaround for SAP calculations on extensions.
