Retrofit Assessment Advice & Coordination

A PAS 2035 retrofit assessment is the foundation of any well-designed whole-house energy upgrade — insulation, ventilation, heating and renewables planned together rather than as one-off measures. EvoHome Improvements helps homeowners across Hampshire and the South understand what a retrofit assessment covers (property condition, occupancy, energy performance, ventilation, moisture risk) and how the output (assessment, design, coordination) feeds into safe, effective measures and grant-funded routes such as ECO4 where applicable.

EvoHome Improvements advises and coordinates; independent vetted retrofit assessors and PAS 2030 installers carry out the assessments, design and installation. We do not guarantee grant eligibility, energy savings, EPC outcomes or specific funding amounts. Retrofit assessments and Energy Performance Certificates (EPCs) provide the foundation for informed decisions about improving your home's energy efficiency.

With energy costs remaining high and government grants available, understanding your property's energy performance has never been more important.\n\n## What is a Retrofit Assessment?\n\nA retrofit assessment goes beyond a standard EPC to provide a detailed analysis of your home's thermal performance, identifying specific improvement measures in the correct installation sequence.

The 'fabric first' approach — insulation before heating systems — maximises efficiency gains and reduces costs.\n\n## EPC Requirements\n\nEPCs are legally required when selling or renting a property. They rate energy efficiency from A (most efficient) to G (least efficient). The government has announced plans to require minimum EPC C ratings for rental properties, making improvements increasingly important for landlords.

\n\n## Grant Eligibility\n\nVarious government schemes fund energy efficiency improvements. ECO4 provides free or subsidised insulation and heating upgrades for eligible households. The Boiler Upgrade Scheme offers £7,500 towards heat pump installations. A retrofit assessment confirms eligibility and maximises grant value.

\n\n## Hampshire Context\n\nHampshire's housing stock ranges from well-insulated modern developments to solid-walled Georgian and Victorian properties. Older properties in Winchester, Lymington and Petersfield often have the most to gain from retrofit improvements, with potential energy savings of 40–60%.
