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.


🧮 Quick ROI Model (Copy/Paste Ready)

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

Savings per property:

Programme-level saving:


📊 Worked Example

  • N = 250 homes
  • £VR = £22/day
  • £DC = £450 (typical single-night + logistics)
  • D_full = 3 days vs. 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
