Electrical Rewiring - Full & Part Rewires

Electrical installations, over time, will deteriorate naturally as they are a working mechanism made up of various components and working systems.

For wiring systems more than 25 years old we would always recommend having the electrical system checked out at regular intervals.

This will help identify any faults or defects which could require improvement. It will also give you an idea of any work that might be required and potential cost if you are considering upgrading the electrical installation or remodelling it to include additional circuits. A full rewire usually takes place when major building work such as an extension or conversion is being carried out – prior to any plastering or decoration.

Other occasions when a rewire might be necessary include;

  • After flood or fire damage
  • If electrical installation has become unsafe
  • Installation of several new circuits
  • Upgrade of building/property


Commonly asked questions


What will a new rewire mean?

Having a full rewire will bring the electrical installation in your property up-to-date with the latest wiring regulations. It will also give you the opportunity to modernise your home with a new consumer unit containing residual current devices (RCDs) and circuit breakers, additional sockets to suit your needs (including USB sockets should you so wish) and the most up-to-date, modern wiring available. It can also be costly and we recommend that you get at least three quotes before arranging for an electrician to carry out a full rewire – as the prices quoted could be markedly different. However, please be aware that the lowest cost does not always mean the best job – so do your research carefully and maybe look at examples of other rewires carried out by the firm you choose to go with. 

Who needs to be notified?

Carrying out a partial or full rewire will often involve creating new circuits or a consumer unit change. This means the work is notifiable to your local building control department. Using a registered contractor with NICEIC or ELECSA means the person carrying out the work is eligible to do this for you – without
the need for you to do anything. Be sure to arrange this with your electrician beforehand and get the appropriate certification for the work afterwards. 

My property is quite old, how do I know if it needs a rewire?

Before ordering a full rewire it might be worth having a full inspection of the electrics beforehand. You should contact your local NICEIC or ELECSA registered contractor and ask them to carry out an electrical inspection (sometimes known as a periodic inspection) of the property. Much like an MOT, this is an inspection of the current condition of an electrical installation in your home. On completion of the inspection, you will receive an Electrical Installation Condition Report (EICR) detailing any damage, deterioration, defects, dangerous conditions and anything not in line with the present-day safety standard which might give rise
to danger. 

How long will a full rewire take?

A full rewire can take, on average up to between 5-10 days, depending on the size of the property. The time taken depends on the number of contractors working and the exact scope of work involved.
