Retrofit Asssessments

We conduct comprehensive retrofit assessments in line with PAS 2035 standards to support decarbonisation and building upgrades. Our service includes energy evaluations, property condition assessments, and occupancy reviews to deliver a holistic view of energy performance. As Elmhurst-accredited Retrofit Assessors, we provide compliant reports that enable effective retrofit planning and funding applications.

Energy Audits

Our energy audits identify inefficiencies across your property, highlighting opportunities for cost savings and environmental impact reduction. We assess energy use patterns, building fabric, and services to recommend practical steps for improving efficiency. These audits are ideal for landlords, councils, developers, and businesses aiming to lower running costs and meet carbon reduction goals.

Sustainability Reports

We provide detailed sustainability reports tailored to your project goals—whether you’re working on new developments, retrofits, or long-term property planning. Our reports align with current environmental standards and planning requirements, supporting responsible investment and helping you demonstrate your commitment to low-carbon outcomes.

Energy Performance Certificates (EPCs)

As qualified assessors deliver fast, reliable EPCs for residential properties across London, Surrey, and Kent. Whether required for sale, lease, or compliance, our EPCs clearly indicate a property's energy efficiency rating, with recommendations to improve performance and achieve better ratings for future assessments.
