SAP Calculations in Scotland
SAP calculations for new homes, conversions and domestic property projects across Scotland. We help developers, architects, builders and homeowners understand energy performance requirements and provide the calculations needed to support Building Standards compliance.
Request SAP calculationsWho needs SAP calculations?
SAP calculations are normally required for new-build domestic properties and can also be needed for certain conversions, extensions or changes to residential buildings. They are used to assess the energy performance of a dwelling and support compliance with Scottish Building Standards.
This service is commonly used by architects, developers, builders, self-build clients, property owners and project teams preparing information for a building warrant or completion submission.
What is included?
We review the property design, construction details and building services information, then prepare SAP calculations that show how the proposed dwelling performs. Where improvements are needed, we can highlight practical options before the project reaches site or completion stage.
- Design-stage SAP calculations for new dwellings
- Review of floor plans, elevations and construction build-ups
- Assessment of insulation, glazing, heating, hot water and ventilation details
- Energy performance feedback for the project team
- Support with Building Standards and completion-stage information
- Clear reporting with practical next steps if changes are required
When should SAP be arranged?
The best time to arrange SAP calculations is during the design stage, before final construction details are fixed. This makes it easier to adjust insulation, glazing, heating systems or renewable technologies if the initial design does not meet the required performance level.
SAP can also be reviewed later in the project, but late changes are often more difficult and may affect cost, programme or specification.
Information we usually need
- Floor plans, elevations and sections
- Construction build-ups for walls, roof, floors and openings
- Window and door specifications
- Heating, hot water and ventilation details
- Renewable technology details, if included
- Air tightness target or test result, where available
FAQs
How quickly can SAP calculations be arranged?
Timescales depend on the size of the property, the quality of the drawings and whether all specification details are available. If your building warrant or completion deadline is urgent, send the drawings and project details as early as possible.
Can SAP calculations be done before construction starts?
Yes. Design-stage SAP calculations are often the most useful because they allow the project team to check performance early and make changes before work begins.
Do you cover all of Scotland?
Yes. We support SAP calculation work for projects across Glasgow, Edinburgh, central Scotland and wider Scottish locations. Most SAP work can be progressed remotely using drawings and specification information.
