Replacement of power cables to a residence

Safe, Reliable Power Supply for Your Home

Your home depends on a stable electrical connection from the street to your meter and consumer unit. When the incoming power cable is damaged, outdated, or undersized, it can lead to flickering lights, tripping breakers, burning smells near the meter, or complete power loss. Replacing the main power cable is not a cosmetic upgrade, it is a safety critical job that protects your household, appliances, and electrical system.

We provide a complete residential power cable replacement service, from inspection and fault finding to safe isolation, installation, and final testing. If you have concerns about your supply cable or have been advised to replace it during an inspection or renovation, we can guide you through the options and complete the work to a high professional standard.

When a Power Cable Replacement Is Needed

Incoming supply cables work hard for decades, often hidden in walls, conduits, or underground ducts. Over time, insulation can degrade and connections can loosen. Changes to your home can also push an older cable beyond what it was designed to handle, especially after adding electric showers, heat pumps, EV chargers, or larger consumer units.

Common warning signs

• Frequent tripping at the main switch or unexplained outages
• Voltage drop, dimming lights, or buzzing from the meter area
• Visible damage to the cable sheath or signs of overheating
• Water ingress near the entry point, duct, or meter cabinet
• Renovations that require relocating the meter or consumer unit
• A failed inspection due to cable condition or incorrect sizing

If you notice any of these issues, it is important to stop using the affected circuit area where possible and arrange an assessment. Our team can confirm whether the problem is within the home side cabling or the utility side connection, and we coordinate next steps accordingly. For related work that supports the overall safety of your installation, we also offer electrical safety services for residential properties.

What Our Replacement Service Includes

Replacing the main power cable requires careful planning and strict safety controls. We focus on doing the job cleanly, efficiently, and with minimal disruption, while ensuring the finished installation is robust and compliant.

Assessment and planning

We start by inspecting the route, entry point, meter position, earthing arrangement, and consumer unit connections. We check cable size against expected load and future upgrades, then propose the best route and cable type for your property, such as armoured cable where additional mechanical protection is needed.

Safe isolation and coordination

Work on the incoming supply must be isolated correctly. Depending on the setup, this may involve coordination with your network operator or meter provider to ensure power is disconnected and reconnected safely. We manage the process and schedule the work so your downtime is kept as short as possible.

Removal and installation

We remove the old cable where accessible, install the new cable along the agreed route, secure it properly, and protect penetrations through walls or ducts. Connections are made using suitable glands, lugs, and enclosures, with attention to torque settings and heat management. We keep the work area tidy and restore access panels or trunking as required.

Testing and verification

After installation, we test continuity, insulation resistance, polarity, and earthing performance. We also verify that protective devices operate correctly and that the supply characteristics match the home installation. If additional improvements are needed, we can advise on electrical upgrades such as consumer unit changes, bonding, or surge protection.

Choosing the Right Cable Size and Route

A power cable replacement is an opportunity to improve reliability and prepare your home for increased demand. Undersized cables can overheat and create nuisance tripping. Oversizing without proper terminations can also create issues. We calculate cable sizing based on your supply type, expected load, installation method, and length, then match it with correct protection and connection hardware.

We also help you choose the best route. In many homes, the cleanest approach is to use existing ducts or conduits where possible. Where a new route is required, we aim to minimise disruption by careful placement, surface containment where appropriate, and weatherproofing at entry points. If your project includes other wiring changes, our electrical wiring services can be aligned with the cable replacement to reduce repeat visits and downtime.

Safety, Compliance, and Homeowner Peace of Mind

Because the incoming cable sits at the heart of your electrical system, the quality of workmanship matters. We follow safe work practices, use suitable rated components, and ensure correct earthing and bonding arrangements. You can expect clear communication, transparent recommendations, and practical advice on how to avoid future issues such as moisture ingress, mechanical damage, or overloaded circuits.

If you are unsure whether your residence needs a power cable replacement, contact us to arrange an inspection and we will help you decide the safest and most cost effective next step.
