Introduction
With rising energy costs and growing concerns about climate change, more UK homeowners are turning to retrofit assessments. A retrofit assessment is the first step in upgrading your home’s energy efficiency under schemes like ECO4. It evaluates your property’s current performance and recommends improvements such as insulation, heating upgrades, and renewable energy options.
What is a Retrofit Assessment?
A retrofit assessment is a detailed home energy survey carried out by a qualified assessor. It checks the building fabric, heating systems, ventilation, and insulation levels. The findings help create a tailored plan for reducing energy waste, cutting carbon emissions, and making your home more comfortable.
Key parts of a retrofit assessment include:
- Energy Performance Certificate (EPC) check
- Whole house survey (walls, floors, roof, windows)
- Heating system evaluation
- Ventilation and moisture check
- Occupancy patterns – how your home is used
Why Are Retrofit Assessments Important?
- Eligibility for ECO4 and PAS 2035 – Required for government-funded energy upgrades.
- Lower bills – Identifies the best ways to cut heating and electricity costs.
- Comfort – Improves warmth and reduces damp or draughts.
- Property value – Homes with better EPC ratings attract higher resale value.
- Net-zero goals – Supports the UK’s mission to lower carbon emissions.
The Retrofit Assessment Process
Step 1 – Initial Survey
An assessor visits your property to record details about construction, insulation, heating, and ventilation.
Step 2 – Data Analysis
The information is used to calculate your home’s current efficiency score.
Step 3 – Improvement Plan
A retrofit coordinator prepares a plan recommending upgrades such as wall insulation, boiler replacement, or solar panels.
Step 4 – Compliance & Approval
All plans follow PAS 2035 standards, ensuring quality and safety.
Step 5 – Installation & Monitoring
Once approved, qualified installers carry out the work, and the home’s performance is monitored.
