Decant Savings Tool

Decants are one of the biggest avoidable costs in retrofit.
This tool helps councils and housing providers calculate how much money can be saved by using Add2Rad to avoid disruptive radiator swaps and unnecessary tenant moves.

🎯 Purpose

The Decant Savings Tool provides a fast, evidence-based way to estimate:

• How many decants can be avoided
• How much can be saved per home
• The overall financial impact across a programme

This supports SHDF business cases, procurement decisions and internal approvals.

📥 Inputs Required

To calculate the potential savings, enter:

• Number of potential decants under a traditional radiator-upgrade approach
• Cost per decant/home (including temporary accommodation, staff time, transport, cleaning, security)
• Expected decants with Add2Rad
  • Usually zero or near-zero, depending on stock condition

These figures allow a clear before/after comparison.
