Replacement of electrical installation

Modernise your property with a safer electrical system

Older wiring and consumer units were not designed for today’s demand. Extra appliances, electric showers, home offices, EV chargers, and modern lighting can push an ageing installation beyond its limits. Replacing an electrical installation is a planned upgrade that improves safety, reliability, and capacity, while bringing your property in line with current standards and everyday needs.

Whether you own a home, rent out a property, or manage a business unit, a full or partial replacement can prevent nuisance tripping, overheating cables, and hard to trace faults. Our electricians assess what can be retained, what must be replaced, and how to complete the work with minimal disruption, clear communication, and tidy workmanship.

When a replacement is the right option

Not every electrical issue requires a full rewire, but there are clear signs that a replacement of the installation should be considered. We start with a structured inspection and practical advice, including the best scope of work for your budget and timeline. If you need broader support beyond a replacement project, our electrical system services cover diagnostics, upgrades, and ongoing maintenance.

Common indicators your installation may be outdated

• Frequent tripping of breakers or blown fuses, especially when multiple appliances run
• Heat marks, burning smells, buzzing sockets, or sparking switches
• Mixed or damaged wiring, brittle insulation, or cables run without proper protection
• Limited sockets, heavy use of extension leads, or unsafe adaptor chains
• No RCD protection, an old fuse board, or a consumer unit that cannot be safely upgraded
• Renovation plans that involve moving walls, kitchens, bathrooms, or adding new circuits

In many properties, previous alterations have created a patchwork system with hidden joints and undersized cables. A replacement allows the wiring layout and protection devices to be redesigned properly, improving both performance and safety.

What the replacement process includes

Replacing an electrical installation can range from a full rewire to a partial renewal of circuits, distribution board, earthing, and bonding. The goal is a system that is correctly rated, clearly labelled, tested, and ready for everyday use. We provide clear options so you can choose the level of replacement that makes sense for your property.

Step by step approach

1. Survey and planning We review the existing installation, identify risks, and discuss your usage, future plans, and preferred socket and lighting locations.
2. Design and scope We propose circuit layouts, protection methods, and equipment choices. This includes special areas like kitchens and bathrooms where extra rules apply.
3. Replacement works We remove or isolate unsafe wiring, install new cabling, back boxes, accessories, and a modern consumer unit where required.
4. Testing and certification We complete full electrical testing, verify polarity and earthing, and provide the relevant documentation for your records.
5. Final checks and handover We walk you through the new layout, labelling, and any user instructions, and leave the site clean and safe.

During works, we prioritise safety and access. We agree where power needs to be off, how to protect floors and furniture, and how to keep essential circuits running where possible. If you also require additions such as extra sockets, outdoor power, or new lighting circuits, our electrical installation services can be combined into the same visit to reduce downtime.

Residential and commercial replacements

The right replacement plan depends on how the building is used and how critical power continuity is. We tailor the approach for occupied homes, rental properties, offices, retail units, and light industrial spaces. For commercial sites, we can schedule works outside trading hours where feasible and coordinate with facilities teams or landlords.

Typical residential works

• Full house rewires, partial rewires, and consumer unit replacements
• New circuits for kitchens, electric showers, heating controls, and immersion heaters
• Upgraded earthing and bonding to meet current safety requirements
• Improved socket and lighting layouts to suit modern living

Typical commercial works

• Distribution board upgrades, circuit separation, and load balancing
• Dedicated supplies for equipment, servers, refrigeration, or workshop tools
• Emergency lighting wiring readiness and safer isolation arrangements
• Clear labelling and documentation to support maintenance and inspections

For both settings, we focus on long term reliability, safe protection, and capacity for future upgrades. If faults appear before or after the project, we can provide electrical troubleshooting to quickly pinpoint issues and keep your system performing as intended.

Pricing, timelines, and what affects the cost

Costs depend on the property size, accessibility, the number of circuits, the condition of existing routes, and the finish required. A straightforward replacement in an empty property is usually faster than a staged replacement in an occupied home where rooms must be completed in sequence. We provide itemised quotes, explain any optional upgrades, and agree a realistic timeline before work begins.

If you are concerned about safety, planning a renovation, or experiencing recurring electrical problems, we can assess your installation and recommend the most sensible replacement scope. Our aim is a compliant, dependable electrical system that you can trust every day.
