What to expect when Rewiring a House
Sorry to say that a house rewiring project can cause a hell of disruption and comes with high costs. A great deal of time goes into rewiring your house, with some projects lasting 8-10 days minimum for completion. Within the rewiring period, you will need to be patient and bear with being in a blackout or your power getting disconnected from time to time. It gets messy sometimes. A typical house rewiring project goes through three phases: the preparation phase, the main project, and the clean-up phase.
The main rewiring project involves the below steps:
You should expect a team of 2-3 electricians in your home, depending on the magnitude of the electrical problem that needs fixing. Open and transparent communication is vital to make the process seamless and easy for everyone involved. Understanding the project's requirements also has to be clear from the onset to avoid wastage of time and resources. After your electrical contractor finishes the job, packs, and leaves, you should notice some effects of the rewiring for about 2-3 days before it all gets back to normalcy.
Can you Rewire a House in Stages?
An entire house rewiring process involves two main stages: the 'first fix' followed by stage two, the 'second fix.' The first fix consists in installing the actual wiring, together with the back boxes for sockets and switches in your house. Stage one execution usually precedes any wall plastering. Here, any old wiring is replaced. Modern twin-earthed wiring is coated with Upvc; thus, you need to check whether the old wiring lacks twin earthing to replace it in the first fix. The first fix is essential for addressing potential problems such as short-circuiting that results from the rot of old wires. Stage two of house rewiring links the electrics by fitting the switches, lights, and the fuse box. Typically, what an electrician does at stage two is update the consumer unit. A consumer unit is crucial for tripping the circuit, which helps to protect people from electrical accidents. For the record, consumer units fall under Part P of the 2005 Building Regulations.

How to Rewire a House Diagram
Electricians use a drawn wiring diagram as a guide during wiring. The diagram typically connects between elements of the circuit and their relations to and from the power source. Homeowners and electricians need a house wiring diagram for the reasons listed below.
Without a wiring diagram, an electrician can only estimate the wiring needed to set up an electrical system. A typical result of this is severe inefficiency. The two possible outcomes are using extra wiring, which leads to wastage because of the additional installation. On the other hand, less wiring will require you to spend time purchasing the wiring deficiency. With the exact value of the wiring amount needed, your budget will be used appropriately to help avoid wastage.
An electrician working with estimates is likely to waste time purchasing more wiring required, which leads to the project taking longer than expected. This could be the case, especially if dealing with quite huge projects like rewiring an entire apartment building.
Dealing with electrical systems requires extreme caution to prevent injuries that could occur anywhere for myriad reasons. However, having a house diagram helps to foresee where points of damage happen to be in the entire chain. That means that your electrician will avoid all open live wires and sharp places. If an electrician suffers any harm from the point of damage in an electrical circuit, that would halt the rewiring project and make you incur treatment costs.
Similarly, when rewiring your house, you are better off having a house diagram for the above reasons.
