Void Time & Decant Savings (ROI)
Model the financial impact of Add2Rad vs. full radiator replacement — cut voids, avoid decants, and deliver SHDF targets on time.
Void Time & Decant Savings (ROI)
Add2Rad reduces programme risk by shortening installs and keeping residents in place.
🎯 Why This Matters
- Void days = lost rent
- Decanting = hotel + transport + admin
- Redecoration = extra trades + delays
Add2Rad keeps the radiator and adds emitter area at skirting level, so installs complete in single access windows with minimal or zero voids.

Inputs (editable):
- Properties:
N - Avg. rent/day loss (void):
£VR - Decant cost per property (if used):
£DC - Install days (full rad swap):
D_full - Install days (Add2Rad):
D_A2R - Redecoration cost per property (swap only):
£RD

📊 Worked Example
N = 250homes£VR = £22/day£DC = £450(typical single-night + logistics)D_full = 3 daysvs.D_A2R = 1 day£RD = £180(patch/paint typical)
Per-home:
- Void:
(3−1)×£22 = £44 - Decant:
£450 - Redecor:
£180 - Total:
£674 / home
Programme: 250 × £674 = £168,500 saved

📋 Evidence to Capture (for Boards & Audits)
- Pre/post flow & return temps; target 35–45 °C design
- Room comfort snapshots (°C at 15–30 min intervals)
- Installer time-on-site logs (per room/per dwelling)
- Resident access success rate (%) and complaints log
- Photos: before, during, after — with emitter metres recorded

🔧 Delivery Playbook
- Pre-survey: identify rooms & metres (3–6 m typical)
- Resident comms: 48-hour notice, 4–6 hour window
- Install: 1-day, in-occupation, no redecoration
- Commission: balance, comfort check, handover sheet
- Data log: time, metres, temps, photos → upload
