Earthing & Bonding
Across South Wales
Professional earthing and bonding services to protect against electric shock. Essential safety work carried out by NAPIT approved electricians across Cardiff, Newport, Swansea and all of South Wales.
Earthing & Bonding Services in South Wales
Earthing and bonding are the most fundamental electrical safety measures in any property. They provide a safe path for fault current to flow to earth, ensuring that circuit breakers and RCDs trip quickly in the event of a fault – protecting you from electric shock.
Many older properties in South Wales have inadequate or deteriorated earthing and bonding. This is one of the most common faults found during EICR inspections. At Megalec Electrical Solutions, we upgrade and install earthing and bonding to current BS 7671 standards.
We provide main earthing conductor upgrades, main bonding to gas and water, supplementary bonding in bathrooms and kitchens, and earth electrode installations. Serving Cardiff, Newport, Swansea, Bridgend, Caerphilly, Pontypridd and surrounding areas.
Why Earthing & Bonding Matters
Your first line of defence
Electric Shock Protection
Proper earthing ensures fault current flows safely to earth, causing protective devices to disconnect the supply quickly.
BS 7671 Compliant
All earthing and bonding work meets current wiring regulations. Essential for passing EICR inspections.
Fire Prevention
Inadequate earthing can cause arcing and overheating, leading to electrical fires. Proper earthing eliminates this risk.
Whole Property Protection
Main bonding connects gas, water, and other metallic services to earth, preventing them from becoming live during a fault.
EICR Remedial Work
Earthing and bonding deficiencies are the most common EICR failures. We resolve these issues quickly and cost-effectively.
Affordable Safety
Earthing and bonding upgrades are relatively low-cost compared to the critical safety protection they provide.

Why Is Earthing & Bonding So Important?
Without proper earthing and bonding, a fault in an appliance or wiring could make metal surfaces live, creating a lethal electric shock risk. Earthing provides the path for fault current to flow, while bonding ensures all metallic parts are at the same potential, preventing dangerous voltage differences.

Frequently Asked Questions
Earthing provides a path for fault current to flow safely to earth, causing protective devices to trip. Bonding connects metallic services (gas pipes, water pipes) to earth so they can't become live during a fault. Both work together to protect against electric shock.
Main bonding upgrades typically cost £150‑£300. Supplementary bonding in a bathroom costs around £80‑£150. A complete earthing upgrade including main earth conductor can cost £200‑£500. We provide fixed quotes for all work.
The only way to confirm is through professional testing. An EICR will check your earthing and bonding as part of the inspection. Common signs of issues include tingling from taps or appliances, or RCDs tripping frequently.
Under current regulations, supplementary bonding in bathrooms may not be required if the main bonding is adequate and all circuits are RCD protected. However, many older properties still need it. We’ll test and advise based on your specific installation.
Yes, earthing and bonding deficiencies are the most common EICR failures and we resolve them regularly. We can carry out the remedial work and arrange re‑testing to achieve a satisfactory EICR result.
Yes. Main bonding to gas and water services is a legal requirement. The bonding conductor connects these metallic services to the main earthing terminal, preventing them from becoming live if there's an electrical fault.
