• 📈 Data-driven outcomes matter: Monitoring and measuring retrofit performance through systematic data collection ensures projects deliver promised energy improvements and identifies issues before they escalate

Understanding the 2026 Quality in Retrofit Summit Framework

The Quality in Retrofit Summit, convened on January 20, 2026, brought together leading built environment professionals at Surveyor's House to address a fundamental question: how can retrofit projects consistently deliver high-quality outcomes? Co-hosted by The Retrofit Academy and RICS, the summit established that achieving quality retrofit requires three interconnected pillars.[1]

The Three Pillars of Quality Retrofit Delivery

Pillar 1: Skilled and Knowledgeable Workforce

The summit identified that competent building assessment forms the foundation of quality retrofit. Ben Nixon from Bailey Garner emphasized that the current practice of 5-day retrofit assessor training courses cannot adequately prepare professionals for the critical responsibilities of the Retrofit Assessor role.[1]

This recognition led to RICS launching the Residential Retrofit AssocRICS pilot pathway, which has already been reported as oversubscribed. This new entry route focuses on mainstream retrofit work and requires candidates to meet RICS standards of competence and ethics through:

• Core competencies in building pathology and construction technology
• Specialized training in retrofit testing, monitoring, and evaluation
• Risk assessment capabilities specific to retrofit scenarios
• Understanding of building performance in use

For surveyors seeking to understand the value of RICS qualifications, our guide on why choose an RICS chartered building surveyor provides essential context.

Pillar 2: Quality Controls Built Into the System

Ben Nixon presented PAS 2035:2023 as an excellent framework that embeds quality from the outset of retrofit projects. However, evidence presented at the summit suggests many sector participants are not following this framework properly.[1]

The summit established mandatory requirements including:

• Retrofit Coordinators must visit every site (not just coordinate remotely)
• Technical inspection protocols at critical project stages
• Quality assurance systems that verify work completion standards
• Documentation trails that demonstrate compliance

Pillar 3: Robust Monitoring and Measurement

Richard Ellis, Director of Sustainability at The Peabody Trust, stressed that "data is king" in retrofit delivery. The summit prioritized the need to monitor and measure retrofit outcomes throughout projects, not just at completion.[1]

This includes:

• Pre-retrofit baseline energy performance data
• In-progress monitoring during installation phases
• Post-completion verification of predicted improvements
• Long-term performance tracking to identify degradation

Retrofit-Focused Building Surveys Post-2026 Quality in Retrofit Summit: Practical Applications for Surveyors

The summit outcomes translate into specific survey methodologies that differ substantially from traditional building surveys. Retrofit-focused surveys require expanded scope, specialized equipment, and deeper technical analysis.
