How to Prepare for Underfloor Heating in a New Build

Installing underfloor heating during a new build is the most cost-effective and efficient time to do it. You’ll avoid the need for retrofitting and get a clean, integrated system from the start.
Here’s how to prepare properly so your UFH installation goes off without a hitch.
1. Choose the Right System Early
- Water-based UFH is the best option for whole-house systems
- Discuss with your builder and heating engineer early in the design phase
- Identify zone layouts and thermostatic controls in the plan
2. Allow for Floor Build-Up
UFH adds depth to your floor, including:
- Insulation
- Pipes or mats
- Screed
Plan door heights, thresholds, and kitchen cabinet plinths accordingly..
3. Install Insulation Below
- High-quality insulation is essential beneath the UFH to prevent downward heat loss. Most systems use:
- PIR boards
- XPS rigid panels
- Foil-backed rolls (for suspended floors)


4. Plan Zones and Controls
- Each room = separate circuit (zone)
- Install wiring or conduit for thermostats
- Choose smart thermostats before second fix
FAQs
Q: Can I add underfloor heating later in the build?
A: Technically yes, but you’ll face more disruption and higher costs.
Q: Do I need a heat pump or boiler?
A: UFH works with both. Heat pumps offer better efficiency in well-insulated new builds.
