Retrofit coordination services for installers - expert support for PAS 2035 compliance
Retrofit projects are complex, fast-moving, and heavily regulated. Installation companies need a coordination partner who can bring clarity, structure, and technical confidence to every stage.
Our Retrofit Coordination service provides exactly that.
We oversee the full end-to-end process, from assessment, modelling and verification through to design. Whilst continuously analysing the risk management. With a standards-led approach and deep industry expertise, we help installers deliver high-quality, compliant, and energy-efficient upgrades with fewer delays, fewer risks, and far greater certainty. Whether you’re working on single-measure projects or managing large-scale programmes, we’re here to keep everything aligned, documented, and running smoothly from start to finish.
End-to-End Retrofit Coordination
As your Retrofit Coordination partner, we can support you with the following…
Retrofit Assessment
A retrofit assessment is carried out to gain a clear understanding of how an existing building performs and where improvements can be made. Through a structured technical investigation, data collection and the assessment identifies opportunities to enhance energy efficiency, comfort, and overall performance.
This process involves a comprehensive survey of the building’s fabric, systems, and structural elements – providing a solid foundation for designing and delivering effective, compliant retrofit solutions.
Retrofit Coordination & Risk Management
A retrofit coordinator plays a key role in managing the entire retrofit process – from the initial assessment through to final handover. Their responsibility is to review retrofit assessments, identify project-specific requirements, and ensure full compliance with industry standards and regulations.
By overseeing every stage of delivery, the coordinator helps identify, assess, and mitigate technical and performance risks. This ensures each project runs smoothly, safely, and to the highest quality standards – giving installation companies confidence that all work is aligned, compliant, and built to last.
Retrofit Design
Our Retrofit Designer sign-off provides assurance that all proposed measures have been technically reviewed and meet the required standards for safe, effective installation. With MCIOB-qualified expertise, we offer specialist oversight on both standard and complex projects, including the ability to sign off high-risk measures where enhanced scrutiny is essential.
This sign-off confirms that designs are suitable for the property, compliant with PAS 2035 requirements, and aligned with best-practice installation methods. By validating risk, performance, and design integrity, we help installation companies deliver confident, fully compliant retrofit solutions that stand the test of time.
PIBI Verification
Our Pre-Installation Building Inspection sign-off ensures that a property is fully prepared and suitable for the measures planned before any work begins. During this stage, we carry out a detailed review of the building’s condition, confirming that all required enabling works, access considerations, and safety requirements are in place.
This sign-off helps identify any potential issues early—such as structural concerns, moisture risks, or access limitations—so they can be addressed before installation starts. By providing clear, practical guidance and verifying readiness, we help installation teams work efficiently, safely, and in full compliance with industry standards.
EPR Modelling
EPR Modelling (Energy Performance Rating Modelling) is a detailed analysis used to calculate how a property currently performs and how it will perform after planned retrofit measures are installed. By using accurate building data and recognised calculation methods, EPR modelling predicts the impact of improvements such as insulation, heating upgrades, ventilation, and renewable technologies.
This modelling helps ensure that the proposed measures will achieve the expected energy savings, carbon reductions, and compliance outcomes. For installation companies, it provides a reliable blueprint for designing effective retrofit solutions and demonstrating the benefits to clients and funding bodies.
With clear, evidence-based outputs, EPR modelling supports confident decision-making and successful delivery across a wide range of retrofit projects.
