About Retrofit-First

Retrofit-First Feasibility Engine converts complex retrofit standards into structured, compliant, decision-ready plans enabling safe, scalable decarbonisation of the UK housing stock.

Founders & System Design

Founded by Avi Sharma, Retrofit-First is designed as a deterministic system rather than an advisory tool. PAS-2035 requirements, building physics, and risk dependencies are encoded directly into executable software logic.

Mohammed Junaid Syed brings structural engineering and on-site delivery expertise, ensuring outputs remain buildable, safe, and aligned with real-world construction and retrofit constraints.

Together, this experience ensures Retrofit-First translates standards into decisions that are practical, defensible, and scalable across real UK housing stock.

Future Mode: Retrofit Intelligence

Retrofit-First is evolving into a decision infrastructure for retrofit portfolios supporting optimisation across cost, carbon, sequencing, and funding alignment.

By learning from delivered outcomes, the platform compounds accuracy over time, forming a trusted digital backbone for long-term UK decarbonisation.

This enables housing providers and lenders to move from project-by-project assessments to portfolio-level planning, with consistent logic, transparent assumptions, and evidence that remains defensible over time.

FUTURE MODE

How It Works

Retrofit-First converts an address into a PAS-2035 aligned, whole-house feasibility plan using deterministic logic, building physics, and risk-aware sequencing.

Homes grouped by risk, cost, and delivery readiness.

Audit ready outputs

6. Audit-Ready Outputs

Evidence, scopes, and reports ready for delivery.

Features

Retrofit-First provides a structured feasibility engine designed to operate safely at both individual property and portfolio scale without reliance on subjective judgement.

Whole-House Sequencing

Fabric-first, no-regrets sequencing logic ensures measures are ordered safely and efficiently across the entire building, reducing performance risk and rework.

Moisture Risk Prevention

Retrofit pathways that introduce moisture or ventilation risk are automatically blocked before they reach delivery, ensuring only safe, compliant measures progress.

Portfolio-Scale Planning

Apply consistent logic across thousands of homes while retaining property-level auditability, full traceability, and supporting evidence throughout delivery.

Why AI Matters

Retrofit-First applies artificial intelligence as a governance and control layer, not as a black-box prediction tool. AI is used to enforce standards, sequencing rules, and risk dependencies consistently across every retrofit assessment.

By learning from validated retrofit outcomes, regulatory frameworks, and professional best practice, the system improves decision accuracy while maintaining full traceability, auditability, and compliance at every stage.

AI enables retrofit decisions to be structured, repeatable, and defensible — by design.
