SAP Calculations for Conversion
Our experienced team of engineers are well-versed in all aspects of energy efficiency, so you can rest assured that whatever the project – Part L1B Conversion or Extension – your home will meet the required standards and be highly efficient.
What are SAP Calculations for Conversions?
It’s important to remember that when it comes to dwellings, conversions can constitute a ‘material change of use’ (sometimes referred to as a “change of use”). This is true if, after completion, the building either now contains an apartment, constitutes one or more dwellings, or has fewer than before. Similarly, a ‘change in energy status’ will occur where a previously unheated space/building is designed to be heated in the future – typically if it is going to be used as a dwelling.
Ultimately, following Approved Document L1 requirements means your new home or conversion must be designed and built with minimal or reduced carbon emissions in mind – something which can be achieved using the Government’s Standard Assessment Procedure (SAP).
What’s Included in Our SAP Calculation Service?
Comprehensive Documentation: We provide all the necessary SAP calculation documentation required for full compliance with the Building Regulations, from the initial Design Stage (Predicted Energy Assessment or PEA) through to the final On Construction stage (On-Construction EPC or OC-EPC).
Expert Guidance for Success: If your project needs a little boost to meet energy efficiency targets, we offer tailored advice and recommendations to ensure a pass every time.
Dedicated Support: We’re with you every step of the way, offering clear communication and answering any questions you may have throughout the SAP assessment process.
Quick Turnaround: We understand that time is of the essence in construction projects. That’s why we prioritise efficiency and offer quick turnaround times for your SAP calculations.
Holistic Building Performance: We understand that a successful project goes beyond just energy efficiency. That’s why we offer a range of complementary services, such as air tightness testing, sound insulation testing, and ventilation assessments, to ensure your building performs optimally across multiple aspects.
How do SAP Calculations for Conversions work?
We are knowledgeable in conducting SAP calculations from plans both established and proposed, as well as providing a comprehensive specification for construction and services. All assessments can be carried out remotely so there is no on-site visit or survey necessary. For compliance, there are several options of SAP Calculations available and we promise to assist you every step of the way towards achieving the best possible outcome. The assessment process features two distinct phases: design, where we guarantee that your concepts comply with L1b SAP standards for controlled fittings, services and building materials; and as-built, which involves us issuing final documentation plus an Energy Performance Certificate (EPC) if applicable.
We also verify existing structures meet regulations while pinpointing ways to enhance them with new elements such as insulation or heating systems. Ultimately, our aim is to make sure each part – old or new – performs at its maximum potential and reduce carbon emissions.
Please note: SAP Calculations are different from an Energy Performance Certificate. Typical SAP Calculations are used to demonstrate to building control how a building or conversion will comply with building regulations due to a ‘material change’ or ‘change in energy status’ while an EPC demonstrats the energy efficiency of a building.
When are SAP Calculations for Conversions needed?
SAP Calculations for Conversions are required when a building is being converted from a non-domestic use to a domestic use, such as from a shop or office to a house classed as a ‘Material Change of Use’ or a Change of Energy Status. The SAP Calculation will assess the energy efficiency of the proposed changes and provide recommendations for improvement where necessary.
When it comes to changes in material use, you may be looking at things like:
- 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.
A transition to a new energy status may be necessary when an unheated area or building is newly intended for heating. It’s also possible that a shift in the usage of a building could result in changes to its energy status. We’re here to guide you through this process and make sure you remain informed and up-to-date with everything related to the alteration of your energy status! Any issues that arise during the process of delivering your SAP Calculations will be handled efficiently by our knowledgeable team, providing peace-of-mind and quick solutions so you can move forward with your plans smoothly.

Frequently Asked Questions
To give you the most accurate SAP assessment and helpful advice, we need a clear picture of your design. Ideally, this means providing us with detailed, up-to-date drawings (electronic format is preferred) and any accredited construction details you have.
The more information we have, the better we can understand its energy performance potential. This typically includes:
Architectural Drawings: Floor plans, sections, and elevations to understand the building’s layout and dimensions.
Site Orientation: A site plan showing the position of existing elements and the orientation of the proposed building to assess solar gain and potential overshadowing.
Construction Specifications: Detailed information about the construction materials and methods for existing walls, new structures, roofs, and floors, including insulation types and thicknesses.
Window Specifications: Details about the type of glazing (single, double, triple), frame materials, and dimensions of all windows.
Heating System Information: Specifications for both primary and secondary heating systems, including their efficiency ratings and any controls.
Renewable Technology Details: If your project incorporates renewable energy sources like solar panels or heat pumps, we’ll need information about their type, capacity, and integration into the building’s systems.
Providing this information upfront allows us to conduct a more thorough and accurate SAP assessment, leading to optimised energy performance and a smoother compliance process.

SAP (Standard Assessment Procedure) calculations are the UK government’s approved method for assessing the energy performance of new dwellings. They predict energy use and carbon emissions, resulting in an Energy Performance Certificate (EPC) rating.
SAP calculations are mandatory for new dwellings to demonstrate compliance with Part L of the Building Regulations (England & Wales) or Section 6 (Scotland). They’re essential for obtaining building permits and ensuring your project meets energy efficiency standards.
Ideally, SAP calculations should be integrated into the early design stages of your project. This allows you to optimise energy efficiency from the outset and avoid costly modifications later. However, a final SAP assessment is also required upon completion for compliance and to generate the official EPC.
Multiple factors impact your SAP rating, including the building fabric (insulation, windows, airtightness), heating and hot water systems, ventilation, lighting, and renewable energy installations.
While it’s best to optimise energy efficiency during the design phase, some improvements can be made after construction. However, these can be more costly and disruptive. A professional SAP assessor can advise on potential retrofitting options.
The cost varies depending on the complexity and size of your project. At Focus360 Energy, our SAP Calculation services start from £80 + VAT, and we offer same-day quotes for your convenience.

SAP Calculations must be carried out by an On Construction Domestic Energy Assessor or OCDEA, working with approved Government program. The Assessor must be certified under one of several accreditation schemes and is regularly audited to keep their certification.
