The Importance of Site Surveys by Underfloor Heating Contractors

Before any pipe is laid or cable run, your underfloor heating installer should carry out a comprehensive site survey. Skipping this step leads to delays, errors, and costly rework.
Here’s what happens during a site survey—and why it matters so much.
What’s Included in a Site Survey?
- Floor level and screed depth assessment
- Subfloor condition and insulation check
- Layout review for pipe runs and manifolds
- Power and boiler capacity checks
- Discussion of thermostat zones and wiring paths
- Flooring type and compatibility check
Why It’s Essential
- Prevents installation delays and clashes with other trades
- Avoids floor build-up miscalculations
- Ensures correct pipe spacing and zoning
- Highlights need for floor strengthening if needed


When Should the Survey Be Done?
- Before 1st fix plumbing and electrical
- Ideally during or just after slab/floor preparation
- Before ordering materials or pouring screed
