Overview
A retrofit assessment is the essential first step in any domestic energy improvement project. Our qualified Retrofit Assessors evaluate the current condition of a property, identify areas of energy loss, and recommend a tailored package of improvement measures — all in full compliance with PAS 2035.
At Synavo, we go beyond ticking boxes. Every assessment is designed to give you a clear, actionable understanding of your property's energy performance and the most cost-effective path to improvement.
Our Process
1. Pre-Assessment Review
We begin by reviewing available data including existing EPCs, floor plans, and any previous survey reports. This allows us to arrive on site fully prepared and minimise disruption.
2. On-Site Property Survey
Our assessors conduct a thorough physical inspection of the building fabric, heating systems, ventilation, insulation levels, and existing energy measures. We use calibrated instruments to capture accurate data on thermal performance.
3. Data Analysis & Modelling
Survey data is entered into industry-approved software to model the property's current energy performance and simulate the impact of potential improvement measures, accounting for building-specific factors such as age, construction type, and occupancy patterns.
4. Improvement Option Evaluation
We assess each potential measure for technical suitability, cost-effectiveness, and compatibility with the property. This includes evaluating risks such as moisture build-up and ventilation adequacy to ensure that improvements are safe and durable.
5. Report & Recommendations
You receive a detailed Retrofit Assessment Report that clearly sets out the recommended measures, estimated energy savings, indicative costs, and a suggested installation sequence. This report forms the basis for any subsequent retrofit coordination.
Key Benefits
- Regulatory compliance — Fully aligned with PAS 2035:2019 and the requirements of government-funded schemes such as ECO4 and GBIS.
- Informed decision-making — Understand exactly where your property is losing energy and which improvements offer the best return.
- Risk mitigation — Each recommendation accounts for potential unintended consequences, protecting your property from moisture damage and other issues.
- Funding eligibility — Our assessment reports are accepted by all major funding bodies, helping you access available grants and subsidies.
- Clear next steps — Every report includes a prioritised action plan so you know precisely what to do and in what order.
Who It's For
Retrofit assessments are suitable for a wide range of clients and property types:
- Homeowners looking to reduce energy bills and improve comfort.
