Retrofit Solutions to Optimise Your Property

Retrofit Assessment
Our qualified Retrofit Assessors carry out a thorough whole-house survey, evaluating your property's current energy performance including insulation, heating, ventilation, and fabric to produce a bespoke, PAS 2035-compliant improvement plan tailored specifically to your home.

Retrofit Coordination
A successful retrofit requires precise planning and expert oversight. Our Retrofit Coordinators manage every stage of your project from design and installer procurement to compliance checks and final sign-off ensuring your retrofit is delivered on time, on budget, and to the highest standard.

Retrofit Installation
From insulation and heating upgrades to ventilation systems and renewable technologies, our TrustMark-accredited installation teams carry out every measure to a high standard. We handle the full installation process, minimising disruption and ensuring quality at every step.

Energy Performance Certificates (EPCs)
Our Elmhurst Energy-accredited assessors provide fast, accurate EPCs for homeowners, landlords, and property sellers. Whether you need an EPC for a sale, rental compliance, or to establish a baseline for retrofit works, we deliver lodged certificates within 24 hours.

Airtightness Testing
Airtightness is a critical measure of energy efficiency. Our certified testers use blower door equipment to accurately measure air leakage in your property providing the data needed to meet building regulations, support retrofit design, and improve overall thermal performance.

Factor Temperature Calculations
Accurate Factor Temperature Calculations are essential for correctly sizing and specifying heating systems within a retrofit project. Our assessors produce detailed heat loss calculations in line with PAS 2035 requirements, ensuring your heating measures are precisely matched to your property's needs.
