Our EPC (Energy Performance Certificate) and SAP (Standard Assessment Procedure) assessment services provide social landlords and housing providers with accurate energy performance data for their housing stock. These assessments are essential for planning and delivering retrofit programmes, securing grant funding, and meeting energy efficiency and net zero targets.
We support retrofit schemes funded through programmes such as the Social Housing Decarbonisation Fund (SHDF), Off-Gas Retrofit Programme (ORP), Energy Company Obligation (ECO) and other government or private initiatives.
What Are EPCs and SAP Assessments?
Energy Performance Certificates (EPCs) rate a property’s energy efficiency and carbon emissions, providing landlords with a clear benchmark of current performance.
SAP assessments are technical calculations that underpin EPC ratings, taking into account:
- Building fabric and construction type
- Heating, ventilation, and hot water systems
- Insulation and thermal bridging
- Energy usage and CO₂ emissions
For non-traditional and hard-to-treat homes, including PRC, Airey, Wimpey No-Fines, Cornish and BISF properties, accurate SAP assessments are critical to correctly plan retrofit interventions and secure funding.
Why EPCs and SAP Assessments Are Essential
EPCs and SAP assessments help landlords:
- Understand current energy performance and carbon emissions
- Identify where energy efficiency improvements are required
- Comply with funding programme requirements (SHDF, ORP, ECO)
- Plan retrofit works and prioritise investment effectively
- Demonstrate compliance with PAS 2035 and other retrofit standards
Accurate assessments ensure retrofit programmes are evidence-based, compliant and cost-effective.
Our EPC and SAP Assessment Approach
We provide a structured, end-to-end service tailored to social housing retrofit:
Stock Data Review
Analysis of property construction, condition and previous EPC data to plan the assessment efficiently.
On-Site Surveys
Inspection of building fabric, heating and ventilation systems, and energy-related components, including non-traditional and hard-to-treat properties.
SAP Calculations
Technical modelling of energy performance using SAP methodology to produce accurate EPC ratings and identify improvement potential.
Reporting and Recommendations
Clear, actionable reports providing EPCs, SAP ratings, and retrofit recommendations aligned with funding programme requirements.
Supporting Retrofit and Grant-Funded Programmes
Our EPCs and SAP assessments are designed to support:
- SHDF and ORP grant applications
- ECO compliance and reporting
- Retrofit project planning and prioritisation
- PAS 2035-compliant retrofit assessments
- Long-term decarbonisation and net zero strategies
This ensures landlords have robust, auditable energy performance data for decision-making and reporting.
Deliverables
Clients receive:
- EPC certificates with official energy efficiency ratings
- SAP assessment reports detailing current performance and improvement potential
- Technical commentary linking building condition and retrofit options
- Documentation suitable for funding applications, boards, regulators and asset managers
Reports are written in plain English, translating technical energy performance data into practical retrofit guidance.
