Energy Efficiency & Compliance

At Ryland Design Services Ltd, we are registered, qualified, and accredited energy assessors, specialising in SAP calculations for new-build domestic properties. Using Elmhurst-accredited software, we produce accurate energy assessments that comply with UK regulations and help create highly efficient homes.

What is SAP?

SAP (Standard Assessment Procedure) calculates the annual energy cost for space heating, water heating, ventilation, and lighting. It also measures CO₂ emissions and generates the Energy Performance Certificate (EPC) required for all new dwellings.

Why It Matters

At the design and building regulation stage, every new dwelling application must include a SAP calculation to demonstrate compliance with Part L of the Building Regulations. Increasingly, local authorities also require:

Energy statements
Overheating assessments
Thermal bridging calculations
Design SAPs and energy efficiency reports

Our team stays up to date with the latest procedures, technologies, and construction methods to deliver:

High-specification design and technical packages
Accurate, compliant calculations
Quality assurance from design through to on-site completion
