Electrical rewiring London: Full and Partial Rewires

What is a complete rewire?

A complete rewire is an extensive replacement of all electrical components of an installation. The term rewiring may be slightly misleading as it may indicate only replacing the existing wiring. 

In most cases this is not accurate as the reasoning behind the rewire is due to the age of the installation this means other components such as the fuse board, sockets lighting etc are likely to be as old, worn, damaged or non compliant.

 A full visual assessment by our engineers and if required partial testing would clearly indicate your requirements. Contact us today to arrange a survey.

What is the process in rewiring a property?

Whilst we use similar methodology for residential and small commercial premises. We try and rewire occupied commercial properties outside of working hours to minimise business disruptions

There are many strategies we utilise while rewiring properties and carrying out rewiring services. It is usually determined by a property’s present living environment. Our ultimate goal is to rewire all or as much of the property as possible while causing as little disturbance to our clients and their homes as possible, but we recognise that it is not always practical or viable to rewire the entire property in one hit. 

Empty properties: An empty house is typically viewed as the ideal setting for rewiring your home or rental property. When houses are empty or uninhabited, less time is required to be spent moving furniture, reinstalling power, and cleaning up at the end of each working day. 

When performing unoccupied rewires, we usually divide the work into two phases. 

Phase 1: The initial fix is completed, which usually takes 2-5 days depending on the size of your property. During this visit, all cables for switches, sockets, and lighting are routed to their proper positions. All back boxes and cable conduits are cut into the plaster and masonry, and the property is left ready for plastering. 

Phase 2: Typically, the second fix stage takes somewhat less time than the first fix. We schedule the second fix job after the entire property has been plastered. We install all of the sockets and switch faceplates, as well as all of the lighting fixtures, during this visit. We also install the consumer unit (fuse board), power up all of the circuits, and certify the installation before handing it over to our customers. 

Occupied properties: are typically perceived as a more challenging environment to operate in since there are numerous additional considerations that can cause delays or disturbance. However, a well-managed and purposeful approach to the repairs can result in a better client experience. 

When it’s convenient, our customers have been known to stay with family and friends while the work is being done. Some may see this as a cheeky suggestion, but our goal remains the same, rewire all or as much of the property with as little disruption to our customers and their homes as possible. This way, more of our time is spent doing the jobs we’re qualified to do rather than labor-intensive tasks like tidying up at the end of each day. 

When the phase 1 and 2 can be combined 

When wiring occupied properties, we understand that you want the job done quickly and with as little disturbance to you and your family as possible. We would install both the first and second fix electrical installations, consumer unit, power up, and certification within the same week. All of your personal things are stowed under dust covers in areas that will be least affected by the rewiring process, and all furniture is replaced back to its original location, even if it necessitates doing so on a daily basis. 

Consumer Unit Installation and its Importance in the Rewiring Process

Upgrading your consumer unit is a vital component of the rewiring process whether it’s a full or partial rewire. The consumer unit also known as a fuse box or fuse board plays an important role in distributing electricity throughout your property and protecting electrical circuits from overloads and short circuits. Ensuring your consumer unit is up to date and functioning efficiently is essential for the safety and effectiveness of your electrical system

When undertaking a full or partial rewire our qualified engineers will assess your existing electrical setup and recommend the most appropriate consumer unit for your specific needs. Factors such as the size of your property, the number and type of electrical appliances you use and any future plans for expansion or renovation are taken into account. This assessment ensures that your new consumer unit will seamlessly integrate with your upgraded electrical system

During the rewiring process, our experienced team will replace outdated or damaged wiring and components enhancing the safety and performance of your electrical system. Upgrading your consumer unit in tandem with rewiring ensures that your entire system operates cohesively and complies with current safety standards and regulations. 

Additionally, modern consumer units often include advanced safety features such as residual current devices (RCDs) which provide extra protection against electric shocks.

In the case of a partial rewire our electricians will carefully assess which areas of your electrical system require updates and focus on those sections. Upgrading the consumer unit in this scenario is still crucial as it ensures the newly rewired circuits are adequately protected and functioning efficiently

By integrating the upgrade of your consumer unit into the rewiring process you can be confident that your electrical system will be operating at its safest and most efficient level. Our commitment to delivering reliable and professional service guarantees that your home or business will benefit from an upgraded electrical system designed to serve you well for years to come

Larger installations egg re-wiring or installation or replacement of a fuse box (consumer unit) are fully tested and an Electrical Installation Certificate (EIC) is issued on completion. Where applicable, notifiable electrical works are also notified to the Local Authority or Building Control

An EICR is a legal requirement for rental properties in the UK and may be required if you are selling your home

PAT Testing 

Portable appliance testing (PAT) is the label used for inspection and testing of electrical appliances and equipment to ensure they are safe to use and clear of any hazards.
