Fixed Appliance
Testing.
Ensure the complete safety and regulatory compliance of your hard-wired electrical appliances, from hand dryers to industrial kitchen ovens, across Northern Ireland.


Essential Safety for
Fixed Appliances.
At CTS Electrical Services, we provide thorough Fixed Appliance Testing (FAT) to ensure the strict safety and legal compliance of your non-portable electrical assets. This includes everything from commercial hand dryers and water heaters to heavy-duty industrial kitchen ovens.
While standard PAT testing covers items with a plug, FAT testing covers equipment wired directly into a fused connection unit (fused spur). This essential testing efficiently identifies potential electrical faults, critical wear and tear or physical damage before it poses a severe operational risk.
Isolation Experts
Our engineers safely isolate complex hard-wired machinery without disrupting adjacent business operations.
Fully Vetted Engineers
All staff are Access NI cleared, enabling secure, uninterrupted testing in schools, care homes, and government facilities.
Digital Certification
We provide immediate digital certification and legally compliant logbook updates the moment testing concludes.


The FAT Testing Process
A specialized technical procedure designed to safely assess high-load equipment without compromising the integrity of your wider electrical grid.
1. Safe Isolation
Before any testing begins, the fixed appliance is safely isolated from the main power supply via its fused connection unit.
2. Formal Visual Inspection
We inspect the appliance casing, flex, and the fused spur itself for signs of thermal damage, wear, or water ingress.
3. Earth Continuity Test
Using calibrated equipment, we test the protective earth path to ensure any fault current will safely return to the ground.
4. Insulation Resistance
We apply a test voltage to verify the integrity of the internal wiring insulation, preventing hidden shock hazards.
5. Re-energise & Function Test
Power is safely restored and the appliance is functionally tested to ensure it operates exactly as intended by the manufacturer.
6. Certification & Labelling
A pass/fail label is securely attached to the appliance, and a detailed compliance certificate is generated via our portal.
Don't Ignore Your
Hidden Hazards.
Many businesses mistakenly believe their annual PAT testing covers all their equipment. However, high-load machinery wired directly into the wall is often ignored, creating a massive blind spot in their health and safety compliance.
Commercial Kitchens: Essential for industrial cookers, dishwashers, and extractors that operate in high-heat, high-moisture environments.
Washrooms & Hygiene: Protects users by verifying the safety of hard-wired electric hand dryers and water heaters.
Insurance Validation: Provides the necessary proof that all electrical assets, not just plugged-in items, are safe.
