TRANSFORMING HOMES, TOGETHER
Delivering High-Quality Retrofit in Line with PAS 2035:2023
At WRAP Retrofit, we deliver end-to-end retrofit services grounded in technical excellence, strategic coordination, and meaningful resident engagement. As an experienced chartered architectural practice, we bring a deep understanding of construction across all RIBA stages—from inception and planning through to technical design, coordination, and delivery. Our approach combines compliance, data-driven decision-making, and a human-centric methodology that ensures retrofit programmes succeed not just technically, but socially.
We provide comprehensive retrofit services aligned with the latest PAS 2035:2023 framework, ensuring that every project meets the highest standards for energy efficiency, occupant safety, and long-term building performance. Our approach is rooted in a whole-dwelling methodology, carefully considering the condition, context, and occupancy of each home to deliver robust, compliant, and future-proof retrofit solutions.
Ultimately, our goal is to improve not just the buildings themselves, but the quality of life and wellbeing of the people who live in them.
What makes WRAP Retrofit different is our integrated approach:
Together, this unique blend of skills allows us to deliver retrofit projects that are PAS 2035 compliant, efficient, and genuinely effective for both clients and communities.
- Architectural expertise across all RIBA stages ensures practical, buildable solutions.
- Strong resident engagement capability enables successful delivery of complex, people-focused retrofit programmes.
- Data-driven and robust processes ensure every project is tailored, coordinated, and outcome-focused.
End-to-end retrofit under one team
From initial assessment through to design, coordination and handover — fully compliant with PAS 2035 at every stage.
PAS 2035 Retrofit Assessments
Our PAS 2035 Retrofit Assessments combine architectural expertise with whole-project lifecycle knowledge to deliver detailed, evidence-based evaluations that shape effective retrofit strategies. Rather than simply gathering data, we interpret it in the context of real buildings and occupants to provide practical, compliant, and property-specific recommendations
PAS 2035 Retrofit Coordination
Our Retrofit Coordination service draws on extensive experience across all RIBA stages to manage complexity, align stakeholders, and ensure full PAS 2035 compliance. By combining technical oversight with strong engagement practices, we deliver even large-scale or complex programmes smoothly and with minimal disruption to residents.
PAS 2035 Design
Our Retrofit Design service combines architectural insight with performance-led solutions to produce designs that are PAS 2035 compliant, buildable, and tailored to each project’s unique constraints and opportunities. Backed by strong technical and construction expertise, we ensure retrofit proposals translate seamlessly from concept to delivery, minimising risk and improving outcomes.
Retrofit Advice
Retrofit Engagement
Our Resident Engagement service addresses one of retrofit’s greatest challenges by “soft landing” complex projects through effective communication and collaboration. We design and deliver tailored engagement strategies that build trust, reduce disruption, and improve outcomes, making us a particularly valuable partner for local authorities and housing associations managing large-scale retrofit programmes.
Quality Assurance
Our certified Quality Assurance processes ensure every retrofit service is delivered consistently, transparently, and to the highest standard. By combining rigorous systems with a data-driven approach, we give clients full confidence that their projects are managed in line with best practice, compliance requirements, and performance expectations.
