Rewiring a property is a complex process that involves multiple stages. The first fix and second fix are terms used in the UK and Ireland to refer to the two main stages of electrical rewiring. The first fix involves the installation of cables, back boxes, and hidden wiring before any plastering or internal walls are completed. The second fix, on the other hand, involves connecting switches, sockets, and fixtures to the wiring installed during the first fix. This happens after the walls have been plastered and insulated. Second fix electrics also include testing all the cables for safety and completing the electrical works for a space.

Second fix electrics are the final touches to a new or renovated space
The first fix involves the installation of cables, back boxes, and hidden wiring before any furnishings or carpets are added to a property. It is the preparation work that lays the foundations for the electrical system. This includes running cables and conduits through walls and installing circuits for the electricity to run through.
The second fix, on the other hand, focuses on customising each element to meet local electrical guidelines and regulations. It involves fitting visible components such as plug sockets, switch plates, light fittings, electric cookers, and showers. It also includes upgrading the fuse board with additional RCDs (residual current devices) to improve safety and take into account extra load.
The second fix stage does not require any structural work and is less disruptive than the first fix. However, it is crucial to plan out everything before starting the second fix. This includes determining your requirements, such as smart lighting, and setting a budget for the job.
The duration of the second fix depends on factors such as the size and type of property, the level of planning, and the number of contractors working on the job. It typically takes half the number of days compared to the first fix stage.

Second fix electrics also involves testing all cables for safety
Second fix electrics involves connecting electrical components to the cables installed during the first fix. This includes visible components like plug sockets, switch plates, consumer units (modern fuse boards), and light fittings. It is important to note that second fix electrics happen after the walls have been plastered and insulated, completing the electrical works for the space.
An essential aspect of second fix electrics is testing all cables for safety. This process involves fitting light switches and power sockets and then conducting tests to ensure they are safe to use. The tests are comprehensive and cover all elements of the electrical system to verify their functionality and safety. This includes testing individual components like light switches and power sockets, as well as the overall electrical system.
The safety tests are crucial to ensure that the electrical installations meet the latest standards and guidelines. In the UK, for example, electrical installations must adhere to the British Standard 5295:1989, which sets stringent environmental standards for spaces serving electronics manufacturers and the pharmaceutical industry. By conducting these tests, electricians can provide certification and ensure the safety of the occupants.
In addition to safety, the second fix stage also focuses on customising each element to meet local electrical regulations. Attention to detail is crucial when it comes to wire colour coding, labelling outlets, switches, devices, and breakers. Metal plates are also used during this stage to provide protection against excess heat exposure and to offer additional technical support for wiring installations.
Furthermore, the second fix stage allows for the integration of smart lighting and security systems. Homeowners can remotely control smart lighting through their smartphones, tablets, or laptops, providing convenience and the ability to control lighting when they are away from home. By informing electricians about security systems, such as burglar alarms, CCTV, and fire alarms, the wiring can be planned to accommodate these systems for a seamless integration.

Metal plates are used in second fix electrics to protect against excess heat exposure
The process of rewiring a property is typically split into two phases: first fix and second fix. The first fix involves the rough wiring of a building, which includes running cables and conduits through walls and installing circuits for the electricity to run through. The second fix, on the other hand, focuses on installation safety and ensuring that all electrical components are connected and functioning properly. This includes connecting switches, sockets, outlets, and fixtures to the wiring installed during the first fix.
Metal plates are an essential component in both first and second fix electrics, but they serve different purposes in each stage. In the first fix, metal plates are used to ensure that all wiring is secure. They act as backings to meters, switches, outlets, and appliance connections, providing a safe and secure way to install the necessary components.
In the second fix stage, metal plates are used to protect against excess heat exposure and provide fire resistance. This is especially important as the second fix involves connecting visible components, such as plug sockets, switch plates, consumer units, and light fittings, which are more susceptible to heat exposure. The metal plates help prevent overheating and potential fire hazards. Additionally, metal plates ensure that the installation meets the required standards of current building regulations and codes.
The use of metal plates in second fix electrics is crucial for maintaining the safety and integrity of the electrical system. They provide a layer of protection against excess heat, which can be a common issue with electrical installations.
