A heat loss survey helps identify where heat escapes from your home, improving energy efficiency and reducing heating costs. It’s useful for homeowners looking to insulate their property, upgrade heating systems, or lower energy bills.

​

What Is a Heat Loss Survey?

​

A heat loss survey uses thermal imaging cameras or manual calculations to detect areas of heat leakage in a building. It helps pinpoint:

✅ Poor insulation in walls, roofs, and floors.
✅ Draughts from windows, doors, and vents.
✅ Cold spots due to air leaks or damp areas.
✅ Radiator & pipe inefficiencies.

​

Types of Heat Loss Surveys

​

1️⃣ Thermal Imaging Survey – Uses infrared cameras to visually detect heat loss.
2️⃣ Blower Door Test – Measures air leakage by depressurizing the home.
3️⃣ Manual Heat Loss Calculation – Engineers calculate heat loss based on insulation, window types, and construction materials.

​

Common Areas of Heat Loss

​

🔥 Walls – Up to 35% of heat loss in uninsulated homes.
🔥 Roof & Loft – Around 25% of heat escapes here without proper insulation.
🔥 Windows & Doors – Draughts and single-glazed windows cause heat loss.
🔥 Floors – Uninsulated floors contribute to 10% of heat loss.

Benefits of a Heat Loss Survey

​

✅ Reduces heating bills by improving efficiency.
✅ Helps identify insulation upgrades needed.
✅ Improves comfort by eliminating cold drafts.
✅ Supports net-zero goals by reducing carbon footprint.
