Immoveable properties like homes are frequently bought and sold. If you have purchased a home that is not modern enough then you obviously have to invest money to make it at-par with the current trends. In this updating mission you may need to redo the wiring of the property. The question is can you perform this rewiring by yourself going DIY or you have to hire a certified electrical expert to do it for you?
Let us explore the answer in the following sections. It is important to make certain things clear right at the word go. Electrical works in residential buildings and properties are guided by a set of regulations whereas the same for business units and commercial premises are completely different.
Since 1 January 2005, all homeowners and landlords in England and Wales have to ensure that every new electrical work carried out in their respective properties is in compliance with the Part P of the Building Regulations. If your work does not comply, for whatsoever reason, you are committing an offence that is criminal in nature, confirm professionals with years of experience in electrical rewiring across London. Your local Building Regulations authorities can compel you undo or redo the work.
There are also regulations for notifiable works. For this kind of works it is important to collect the Building Regulations Compliance Certificate after the work is finished. Else you are committing an additional offence. Complete electrical rewiring comes under notifiable works across both England and Wales.
Considering the way the real world goes by it is always better to apply for the approval from the local Building Regulations department right from start. In order to get the relevant approval you have to organise a number of appropriate inspections. On the other hand you get the necessary approval absolutely hassle-free when a qualified electrician does the rewiring of your house. Remember, in case you fail to get the approval from the relevant body you have to declare that to every prospective buyer at the time of selling the house. There are some other clauses too that are worth mentioning here.
If your property has not been rewired in the last 25 to 30 years, chances are higher that it needs to be upgraded to restore it to the current standards. However you can get this rewiring done in parts. Electrical wirings over 25 to 30 years old are considered unable to cope with the requirements of contemporary living and potentially hazardous.
If you undertake a massive remodelling plan that involves material alteration as per definitions of the Building Regulations authority then it is more likely that you have to rewire the house either in part or in full. And that inflates your full house rewire cost as you also have to upgrade the consumer unit or the fuse box at the same time.
If you are converting an attic into garage or extending your home, the work is considered new and thus the new wiring has to comply with Part P of the Building Regulations. Even the existing wiring requires to be upgraded so that the additional load is handled safely. It is also important to ensure the wiring is properly earthed and the cross bonding is correctly done. In circumstances of remodelling or extending a property, there is no need to upgrade the rest of the existing wiring; rather only the part needed for energy efficient system is to be upgraded. In other words that is the central heating control that needs to be rewired.
As far as rewiring is concerned, right from carrying out the initial survey to the core rewiring job should be conducted by qualified electricians. The initial survey will cost you somewhere around £150 while the report will come at £350.
It is practically impossible to give you the exact figures of rewiring a house because the cost of the materials needed for the job varies at times. However about few years back rewiring a 3-bed semi used to cost approximately £3,500. The prices have only spiralled up since then specially in the wake of the ongoing pandemic. Moreover the cost varies on location, points out a professional with years of experience in house rewire across London.

- A competent person like a registered electrician
Accessing the first two options is not very easy until and unless you know such individuals in person. The best and most suitable option is a registered electrician.
