SANS 10142 Compliance – Why It Matters
Underfloor heating systems fall under SANS 10142‑1: The Wiring of Premises. Non-compliant systems present serious fire, shock, and insurance risks.
Our compliance checks include:
Earth continuity testing
Insulation resistance measurement
Correct circuit breaker and RCD protection
Load calculation verification
Safe termination and wiring practices
Where required, we collaborate with registered electricians to ensure full legal and safety compliance.
FAQ – Underfloor Heating Repair
Can underfloor heating be repaired without removing tiles?
Yes. In most cases, thermal imaging and electrical testing allow localised repairs without lifting the entire floor.
Why does my underfloor heating trip the breaker?
This is usually caused by cable damage, moisture ingress, insulation failure, or incorrect circuit protection.
Is it cheaper to repair or replace underfloor heating?
Repairing is almost always more cost-effective when faults are detected early.
Do you repair systems installed by other companies?
Yes. We repair and test all electric underfloor heating systems, regardless of installer or brand.
Is compliance testing mandatory?
Compliance is essential for safety and insurance validity and is strongly recommended after any repair.

Yes, most underfloor heating issues can be resolved. Common problems such as water leaks, air trapped in the system, or blocked pipes are usually repairable when handled by a qualified technician. In some cases, sections of the floor covering may need to be lifted to allow proper access for repairs.
Underfloor heating issues can sometimes be caused by a faulty thermostat or wiring. Check your thermostat settings, consult the user manual, and ensure that the floor sensor or probe is working correctly and properly connected to the thermostat.
The repair process typically involves identifying the fault—often using a fault finder or thermal camera—removing the damaged section, and reconnecting it with a manufacturer-approved repair kit using specialized connectors and heat-shrink tubing to ensure a watertight, electrically safe joint. The system is then tested for continuity before the flooring is restored.
