Electrical Rewires

What is Electrical Rewiring?

Electrical rewiring is the process of replacing, upgrading or altering the existing wiring within a property. This may involve a full rewire of the installation or partial rewiring to specific areas, circuits or rooms.

Rewiring may be required where the existing electrical installation is outdated, damaged, unsafe, overloaded or no longer suitable for the needs of the property. It can also be required during refurbishments, property upgrades, change of use, kitchen or bathroom works, landlord compliance works or after an unsatisfactory Electrical Installation Condition Report.

Common signs that a property may require rewiring or further investigation include frequent tripping, flickering lights, damaged accessories, burning smells, overheating, old rubber or fabric cabling, poor circuit identification, insufficient socket outlets, no RCD protection, visible deterioration or repeated electrical faults.

Older installations may not meet the demands of modern electrical use. Additional appliances, heating systems, electric showers, kitchens, outdoor supplies, security systems, fire alarm equipment and electric vehicle charging can all increase demand on an existing electrical system.

Electrical rewiring should be carried out by a competent electrician and designed, installed, inspected and tested in accordance with BS 7671, the IET Wiring Regulations. Correct cable sizing, protection, earthing, bonding, RCD or RCBO protection, labelling and certification are all important parts of a safe and compliant installation.

The Benefits of Professional Electrical Rewiring

Professional electrical rewiring helps improve the safety, reliability and compliance of a property’s electrical installation. Older or damaged wiring can create risks such as overheating, nuisance tripping, electric shock, fire risk, damaged accessories and unreliable power supplies.

A properly planned rewire allows the installation to be upgraded to suit the current use of the property. This may include additional sockets, improved lighting layouts, dedicated appliance circuits, bathroom and kitchen supplies, smoke alarm circuits, extractor fan supplies, external power and upgrades to consumer units or distribution boards.

Professional rewiring also helps ensure that the installation is designed, installed, inspected and tested correctly. This includes correct cable sizing, circuit protection, RCD or RCBO protection, earthing and bonding arrangements, labelling, containment, accessibility and certification on completion.

For landlords, managing agents and commercial clients, rewiring can also help address issues identified during an Electrical Installation Condition Report. Where an installation is outdated, overloaded or unsafe, rewiring may be the most practical long-term solution rather than repeated temporary repairs.

Choosing the Right Electrical Contractor

Choosing the right electrical contractor is important when planning a full or partial rewire. Rewiring can involve significant disruption, access planning, containment, chasing, making good, testing and certification, so the work should be completed by a competent and reliable contractor.

A suitable contractor should be able to assess the existing installation, explain the recommended works, provide a clear quotation and advise on practical options for the property. This may include socket positions, lighting layouts, consumer unit upgrades, smoke alarm requirements, extractor fan supplies, appliance circuits and future electrical demand.

The contractor should also understand the importance of safe working practices, especially in occupied homes, managed properties, communal blocks and commercial premises. Clear communication is essential so clients understand the scope of work, timescales, access requirements and any areas that may need making good after the electrical works are complete.

We can support homeowners, landlords, managing agents, housing providers and commercial clients with planned rewires, partial upgrades and remedial works following electrical inspections.

The Electrical Rewiring Process

The rewiring process normally starts with an initial assessment of the property and the existing electrical installation. This helps identify the condition of the wiring, consumer unit, earthing and bonding, circuit layout, accessories and any areas requiring upgrade or replacement.

Once the requirements have been reviewed, a scope of works can be prepared. This may include full or partial rewiring, new sockets, lighting alterations, consumer unit replacement, smoke alarm supplies, extractor fan supplies, appliance circuits, external power and any required remedial works.

Before works begin, access requirements, working areas and expected disruption should be agreed. Rewiring may involve lifting floors, chasing walls, installing containment, isolating circuits and coordinating with other trades where plastering, decorating or making good is required.

During the works, existing defective or outdated wiring is removed or safely disconnected where appropriate, and new wiring is installed to the agreed layout. Circuits are then connected, labelled, inspected and tested.

On completion, relevant certification can be provided to confirm the works carried out and support client records, compliance files and sign off. Corevia Group can also provide photographs, job notes and recommendations for any additional works identified during the project.
