Comprehensive Testing for Every Need
Electrical testing is not just about compliance — it's about identifying hidden dangers before they cause harm.

Every test is carried out by a qualified, NICEIC-registered electrician using calibrated equipment, with results recorded on official documentation accepted by insurers, mortgage lenders, and local authorities.
For homeowners, periodic inspection identifies deteriorating cables, overloaded circuits, and inadequate earthing that routine maintenance might miss. For landlords, testing ensures legal compliance and tenant safety. For businesses, regular testing maintains insurance validity, protects staff, and demonstrates duty of care. We tailor our testing approach to your specific requirements, ensuring you get the right level of inspection without unnecessary cost.

Gareth's service was excellent — he came on time, kept me updated via text of what time to expect him, installed the light fitting with the minimum of fuss and I feel was great value for money. No complaints, will use again.

Gareth from Cardiff Electrical Home Rewire recently completed a full rewire of our house and we couldn't be happier with the service. From start to finish, Gareth was fantastic. His communication was excellent throughout the whole job.

Recently had a full rewire. Gareth and his team were professional from start to finish and kept you up to date at every opportunity. They tidied up at any given time, along with wearing coverings for their footwear, so much respect for our home.

What Happens If You Delay Testing & Inspecting Cardiff?
Ignoring electrical issues is one of the most common — and dangerous — decisions property owners make. Here's what you risk by waiting.
Undetected Cable Degradation
Cable insulation deteriorates gradually over decades. Without testing, degraded cables continue carrying current until they arc and ignite.
Inadequate Earthing
Proper earthing is invisible to casual inspection. Testing verifies earth continuity and impedance, confirming protection will operate during a fault.
Failed RCD Protection
RCDs can fail without warning. Annual RCD function testing confirms these life-saving devices will operate when needed.
Invalid Insurance
Many insurers now require proof of regular electrical testing. Without it, policies may be voided and claims refused.
Legal Non-Compliance
Landlords and businesses failing to maintain safe electrical installations face fines, prosecution, and unlimited liability for injuries.
Property Transaction Delays
Missing or failed electrical reports routinely delay property sales and lettings, causing financial loss and chain collapses.

Periodic Inspection vs EICR
An EICR (Electrical Installation Condition Report) is the modern name for a periodic inspection. Both terms refer to the same comprehensive assessment of a fixed electrical installation's safety and condition. The inspection covers all accessible wiring, accessories, and protective devices, with instrument testing of every circuit. For homeowners, the recommended interval is every 10 years or on change of occupancy. For landlords in Wales, it is legally required every 5 years. Commercial premises typically need inspection every 5 years or as determined by risk assessment.
PAT Testing for Businesses
Portable Appliance Testing (PAT) examines plug-in electrical equipment for safety. While not a legal requirement in itself, the Electricity at Work Regulations 1989 require that all electrical equipment be maintained in a safe condition. PAT testing is the most common way businesses demonstrate compliance. We test all classes of equipment — Class I (earthed), Class II (double insulated), and Class III (SELV) — using calibrated PAT testers that check earth continuity, insulation resistance, polarity, and functional operation. Each item receives a pass/fail label and a detailed asset register is provided.
Thermal Imaging Inspections
Thermal imaging uses infrared cameras to detect heat anomalies in electrical systems without physical contact. Hot spots indicate loose connections, overload, or imbalanced loads that visual inspection cannot identify. We offer thermal imaging as an add-on to standard inspections or as a standalone service for commercial switchrooms, distribution boards, and high-load installations. Thermal surveys are particularly valuable for identifying developing faults before they cause failure or fire.
