PAS 2035 Retrofit Services With AES  

We offer a range of PAS 2035 Retrofit Services, including:

A comprehensive Retrofit Assessment is the foundation of any successful PAS 2035-compliant retrofit project. Our in-house expert Retrofit Assessors deliver a complete package, including an Energy Performance Report, Condition Report, Ventilation Survey, and Detailed Floor Plan, with additional Significance Assessments for historic buildings as needed. Accredited by ECMK/PAS Hub and Elmhurst and equipped with L3 historic buildings training, our team ensures every assessment is precise, thorough, and fully compliant.

Our Retrofit Coordinators ensure PAS 2035 compliance throughout the project, managing everything from the initial Retrofit Assessment to Improvement Option Evaluation, Medium-Term Plan, and final Ventilation Assessments, while handling all necessary lodgment to Trustmark for regulatory compliance and smooth delivery.

Effective portfolio analysis and archetyping allow us to develop targeted retrofit strategies that maximise energy efficiency and cost-effectiveness across multiple properties. This analysis prioritises improvements, evaluates options, and ensures that energy goals are met with precision, delivering tailored solutions that are both effective and efficient.

We offer a comprehensive, turn-key WH:SHF solution designed for social landlords, covering every step from bid submission to post-monitoring. Our end-to-end approach ensures compliance, precise planning, and energy-efficient outcomes that meet budget and timeline targets, with transparent communication at every stage for complete stakeholder satisfaction.

With expertise in securing funding for energy efficiency projects, we support clients in maximising available resources through initiatives like WH:SHF, ECO4, HUG, LADS, and GBIS. This funding assistance helps make retrofit projects financially viable while enhancing their overall impact.

Accurate U-Value calculations provide essential data on thermal performance, enabling more effective insulation improvements. Our Condensation Risk Analysis (CRA) identifies potential problem areas, reducing risks of mould and structural damage for a healthier, more resilient building.

PSI value calculations address thermal bridging, crucial for minimising heat loss at junctions such as where walls meet floors or roofs. By accurately measuring and mitigating thermal bridges, we enhance the building’s energy efficiency, achieving significant improvements in thermal performance.

Identifies air leakage points, crucial for maintaining a high level of energy efficiency and compliance.

Ensures adequate ventilation, essential for indoor air quality and compliance with PAS 2035 standards.

Conducted during assessments, these inspections allow us to verify cavity conditions and insulation presence, aiding in precise project planning.

Assesses the effectiveness of ventilation systems to maintain air quality and prevent damp or mould issues.
