SMART, COMPLIANT RETROFIT DESIGN
Design & Retrofit Planning
DATA-DRIVEN ROADMAPPING
Planning That Works in Practice
Successful retrofit starts with robust design and careful planning. Poorly considered retrofit solutions can lead to performance gaps, resident dissatisfaction, and long-term asset risk. WarmPro's Design & Retrofit Planning service ensures that retrofit projects are properly assessed, correctly specified, and designed to perform technically, financially, and operationally.
Whole-House Performance
PAS 2035 Compliant Design
Resident-Focused Delivery

AN EVIDENCE-BASED ROADMAP
Whole-House, Fabric-First Design
Our design philosophy follows PAS 2035 principles, focusing on whole-house retrofit rather than isolated measures. We prioritise improving building fabric first, reducing heat demand before introducing low-carbon technologies.
This approach delivers:
-
Improved comfort and indoor air quality
-
Reduced system sizing and long-term running costs
-
More predictable performance outcomes
OUR APPROACH
Technical Planning for Real-World Performance
WarmPro's retrofit designs are shaped by delivery experience. We understand what works on site, what residents accept, and how to translate technical standards into practical outcomes. Our planning ensures projects are deliverable, explainable, and appropriate to each household. The result is retrofit planning that supports smooth delivery, compliance confidence, and long-term asset performance.
Retrofit Assessments & Surveys
Detailed property assessments identifying building conditions, occupancy patterns, moisture risks, and technical constraints. Our certified assessments provide accurate baseline data for safe, compliant retrofit design.

Energy Modelling & Performance Forecasting
Advanced thermal modeling predicting energy savings, carbon reductions, and system performance post-retrofit. Our modeling ensures measures integrate correctly and deliver intended outcomes with realistic forecasting.

Ventilation Strategy
Design
Comprehensive ventilation design managing moisture and air quality throughout retrofit. Our ventilation strategies prevent condensation risk, ensure regulatory compliance, and maintain healthy indoor environments in improved fabric conditions.

PLAN COMPONENTS
What We Deliver
Our planning and design services include:
Retrofit assessments and property surveys
Technical design and measure specification
Energy modelling and performance forecasting
Ventilation strategy design to manage moisture and air quality

PRACTICAL RETROFIT SOLUTIONS
Designed for Occupied Homes
Much of the housing stock we work with is occupied, often by vulnerable residents. Our retrofit plans are developed with a clear understanding of access constraints, safeguarding considerations, and resident engagement requirements. We design solutions that are deliverable, explainable, and appropriate to each household.
DELIVERY-INFORMED DESIGN
Why WarmPro
WarmPro's designs are shaped by delivery experience. We understand what works on site, what residents accept, and how to translate technical standards into practical outcomes. The result is retrofit planning that supports smooth delivery, compliance confidence, and long-term asset performance.
