Quality Assurance & Technical Monitoring

Quality assurance & technical monitoring for retrofit installations

Technical monitoring service provides independent and structured quality assurance across every stage of retrofit and heating installations, verifying that all works are installed to the required standard and ensure full alignment with the latest industry regulations and guidance.

Our experienced inspectors carry out thorough checks to identify any non-conformances early, working collaboratively with installers to manage corrective actions and gather clear and comprehensive evidence to demonstrate compliance for manufacturers, regulatory bodies and funding organisations. This structured approach helps minimise technical risk and improve installation quality, contributing to safer, more consistent and compliant project outcomes.

Retrofit Technical Monitoring Services

As your Quality Assurance partner, we can support you with the following…

Throughout every stage we work closely with installers to diagnose issues, recommend effective solutions and monitor the completion of any remedial actions. This end-to-end approach ensures installations remain compliant with manufacturer specifications, energy company obligations, TrustMark requirements and funder criteria.

We provide full oversight of the entire installation lifecycle from the initial survey through to final sign off to ensure compliance with PAS 2035, manufacturer specifications, TrustMark frameworks, energy company or utility obligations, Ofgem rules and funder requirements.

Our structured C1, C2 and C3 compliance pathway ensures installations are technically sound, audit ready and fully aligned with the standards expected across the retrofit and energy efficiency sector. This results in reduced technical risk, improved installation quality, stronger consumer protection and complete peace of mind for both clients and installers.

C1 Pre Installation Inspection

Our C1 inspection delivers a detailed pre-works assessment of the property to confirm that the proposed measure is suitable, safe and fully compliant before any installation begins. At this stage we evaluate the condition of the building, identify any defects or constraints and assess risks that may influence performance or compliance. By validating feasibility early and highlighting any required enabling works, we help installers prevent delays, avoid unforeseen issues and reduce the likelihood of non-compliance later in the process. This clear and evidence based starting point, ensures every project begins with a strong and reliable foundation.

C2 Mid Installation Inspection

The C2 inspection is carried out during live installation to provide real time quality assurance at the point where it has the greatest impact. Our technical inspectors review methodology, workmanship, material selection and system build up to ensure that all work aligns with manufacturer specifications, PAS requirements and scheme rules.

Where non-conformances are identified, we offer clear and practical guidance so issues can be corrected immediately, preventing defects from becoming part of the final installation. This stage supports smoother delivery, stronger performance outcomes and greater confidence for both installers and funders.

C3 Post Installation Inspection

The C3 inspection is the final verification stage, confirming that every measure has been installed correctly and that all corrective actions identified during earlier inspections have been fully completed. We assess the finished installation, review all supporting documentation, photographic evidence, and verify that the work meets audit, compliance and scheme requirements.

This final sign off confirms that the project has been delivered to the required standard. It provides installers with complete confidence that the installation is compliant, robust and fully audit ready.
