Part P Electrical Regulations

The UK has a strict set of guidelines and regulations when it comes to electrical work and installations. Compliance with these regulations is mandatory to minimise the risk of electricity-related accidents and injuries.

Back in 2005, the UK Government introduced electrical safety rules as part of the Building Regulations, also known as Part P Electrical Regulations, for England and Wales for the safety of electrical installations in domestic properties.

The main purpose of these regulations is to make sure that all electrical work and installations carried out in homes meet safety standards and is safe for use for all. Read on to find out all about Part P Electrical Regulations and how you can show compliance with them:


Unsafe electrical installations in homes are one of the major causes of injuries such as shocks and burns, and in serious cases, they may even be life-threatening.

To help address the issue and to minimise the risk, electrical safety requirements were included in the Building Regulations. Part P of the Building Regulations pertains especially to electrical installations in homes and dwellings and focuses on electrical safety.

They are intended to maximise the safety of domestic properties by making sure the design and installation of the electrical systems are safe and compliant. They also focus on the inspection and testing of electrical installations in case they are new, extended, or altered.

Part P of the Building Regulations is the only legislation that protects homes and homeowners from unsafe electrical work. They also increase customer satisfaction and confidence in the quality and standard of the electrical work and make it more difficult for unprofessional electricians to deliver sub-par quality work.

As of 1st January 2005, it became a legal requirement in the UK for all work related to fixed electrical installations in dwellings and associated buildings to comply with the relevant standards for electrical safety – BS 7671:2018. These standards cover all the requirements for the design, installation, inspection, testing, and certification of electrical installations.

The current and most recent edition of Part P of the Building Regulations came into effect in 2013 and applies to all electrical work carried out henceforth.


Part P applies to fixed electrical installations in buildings as well as portions of buildings that include:

  • Dwelling houses
  • Flats
  • Maisonettes
  • Properties with a shared communal area such as corridors and stairs
  • Properties with a common supply, for example, shops and public houses with a flat above
  • Shared amenities of blocks of flats, for example, gyms and laundries
  • Outbuildings such as sheds, greenhouses, and detached garages with a shared supply from a local dwelling

According to the law, the responsibility for complying with Part P of the Building Regulations falls on the homeowner or landlord of the property. They must provide documented evidence that all the electrical work falls within the safety standards.

The inability to do so is a criminal offence that can land them in serious trouble and even invalidate their home insurance. The local authorities reserve the right to remove any electrical works that do not comply with the regulations. It may also lead to prosecutions in the Magistrates’ Courts.


Part P Electrical Regulations cover certain types of electrical work carried out in dwellings, both by professionals or DIYers, and they include:

New electrical installations:

All new electrical installations fall under Part P of the Building Regulations. They may include the installation of the wiring, circuits, consumer units, and other related electrical equipment.

Alterations and additions to electrical installations:

Any alterations or modifications done to the existing electrical installations all fall under Part P. They may include making changes or adjustments to the circuits, sockets, or electrical layout.


Repairs and replacements of existing electrical installations also fall under Part P of the Building Regulations. They include repairing or replacing the consumer units and repairing faulty wiring or rewiring parts of the electrical system.

It is very important to note that not all electrical work is covered by Part P Electrical Regulations. Certain works such as general repair and maintenance of electrical equipment are not covered by Part P.

However, to ensure that all the work is carried out safely and in accordance with the safety standards, it is crucial to follow best practices and regulations.


If you live in any one of the properties mentioned above, you will have to understand the type of work being carried out and whether it needs to be compliant with Part P Electrical Regulations.

Broadly speaking, there are two types of work being carried out: notifiable and minor work. Both categories determine the level of compliance required for the electrical installation.

It is important to understand the difference between the two as the type of work determines the level of complexity and risk involved. If you are unsure, you can always consult with a qualified electrician or relevant local authority to get a better idea.

You are responsible for the safety of the electrical installations on your property, and failure to comply with Part P on any electrical work is a criminal offence that can also invalidate your home insurance.

Notifiable work refers to all the electrical installations that require the local building control authority to be notified before being carried out. It is significant in nature and must be carried out by a registered and certified electrician.

Once the notifiable work has been completed, the electrician must provide a relevant certificate to prove and certify compliance with Part P.

Notifiable work may include things like:

Minor work, on the other hand, refers to all electrical installations that are not as significant and pose a lower level of risk. They do not need any notification or certification and can be carried out by any competent individual, including the homeowner.

It is important to note though that although minor work doesn’t require any certification, it is always recommended to keep a record of any work carried out on your property for future reference and when selling it.

Minor work may include things like:

  • Installing a new socket or light fitting to an existing circuit
  • Replacing damaged cable for a single circuit
  • Replacing a single socket or switch
  • Replacing a light fitting that is not in a special location.


The UK has a strong emphasis on electrical safety in all types of properties and has a lot of regulations in place to make sure everybody complies with them. Despite that, 80% of the public is unaware that certain types of work require the local authorities to be notified and have to be carried out only by certified electricians.

The first step to showing compliance with electrical safety is to stay informed and up-to-date with the laws and regulations governing electrical systems and installations. Knowing what the Building Regulations are and what kind of work is covered by Part P will help you stay compliant and ensure electrical safety.

The second step is knowing who to trust with carrying out the electrical work in your home so that it is both safe as well as efficient.

When looking for someone to carry out electrical work in your home, you have two options, both of which involve compliance with Part P.

  1. The first option is to have the work completed by a registered electrician. This is the best option and is strongly recommended if you wish to have safe, smooth, and reliable results. Also, since the electricians are able to self-certify their work as they are registered with a government-approved Part P scheme provider, it is a relatively hassle-free process. Registered electricians work in compliance with the safety standards and all their work meets the UK Wiring Regulations BS 7671. To check if your electrician is registered, you can check on the Electrical Competent Persons Register to find out their status.
  2. The second option is to hire an unregistered electrician who will be required to notify the council before starting any notifiable work. They will need this to receive approval before beginning work. After the work has been completed, they or the council must hire a registered electrician to test and inspect the work that has been carried out in order to ensure it complies with the Building Regulations. You will also have to make sure that you receive a compliance certificate at the end of the work. It is important to note that, unlike registered electricians, unregistered electricians cannot self-certify their work.

If you compare the two options, it is always better to hire a registered electrician to carry out any electrical work on your property. You don’t have to go through the formalities yourself and can fully rely on them to safely complete the job.

You do not have to interact with the council or local authorities at all. All you have to do is deal with the electrician and let them take care of everything.

Registered electricians can make the process incredibly simple for you and will always ensure that the work is compliant with Part P Electrical Regulations.


Showing electrical compliance is important for homeowners for several reasons that include:


You’d be surprised to know the number of accidents, injuries, and even deaths caused by the negligence of electrical safety. Non-compliant electrical work can be the cause of electric shocks, burns, fires, and other hazards.

Electrical regulations were put in place for one very important reason – safety. By complying with the regulations, you can make sure that all your electrical installations are safe to use. You can also provide documented evidence that the work has been carried out following the relevant safety standards.

Legal requirement

Adherence and compliance with electrical regulations not only guarantee safety but is also a legal requirement in the UK. Failure to comply with them can land you in some serious trouble and can result in heavy penalties and even criminal charges.

By being compliant and by showing evidence, you can fulfil your duty as a responsible citizen and avoid any adverse consequences as a result of non-compliance.

Insurance coverage

Compliance with electrical regulations may be a requirement of many insurance companies for providing coverage. Non-compliance can invalidate your insurance claims in the event of an electrical incident or accident.

By showing compliance with Part P Electrical Regulations, you can provide proof that you have taken the necessary steps to mitigate and minimise risk.

Since compliant work is safer and more reliable, the chances of accidents and injuries happening are much lower, which is something that insurance companies value. Depending on your insurance provider, they may also offer discounts on premiums for clients that show compliance.

Increased property value

By making sure that the electrical installations on your property are all compliant with safety regulations, you can play your part in positively impacting the value of your property. Having the necessary paperwork that proves the safety and reliability of the electrical systems and installations can both enhance the value of the property and increase its marketability.

This can be particularly beneficial if you plan on selling your property. Compliant electrical work can give you an edge over the competition and make your property more lucrative to potential buyers.

Building control approval

If you are looking to obtain building control approval for new construction, renovations, alterations, or additions, you will have to show documented proof of compliance with electrical regulations.

The building control authorities often ask for paperwork as well as certification before approval so that they can be sure that your property meets the necessary safety standards and is legally authorised to carry out construction, alterations, and additions.

Peace of mind

Last but certainly not least, compliance with electrical regulations gives you peace of mind knowing that all the electrical installations on your property are safe to use and do not pose a hazard.

As a homeowner or landlord, it is your responsibility to ensure safety on your property, and one of the easiest and most reliable ways to guarantee electrical safety is to demonstrate compliance with electrical regulations.
