Whether it's installing a new circuit or setting up solar panels and battery storage, the decision of which electrician to choose is crucial when the task involves fixed wiring within the home. Any homeowner who is seeking a Part P Electrician is normally seeking someone who can carry out any electrical work in the home which is relevant to Part P, safely, and if applicable, sign it off as compliant with Building Regulations.
But Part P electrician is not a distinct job title or stand-alone electrician qualification. Part P relates to the Building Regulations and electrical safety in dwellings, and some types of work can be self-certified by an electrician who has registered to a government-approved Competent Person Scheme.
This guide will walk you through what Part P registration is, what jobs as an electrician might need to be notified for, checking if an electrician is registered, and what paperwork will be required after. It also considers the importance of electrical planning when a solar PV or home battery storage system is being installed.
The Role of a Part P Electrician in Domestic Electrical Work
It is important to know the difference between technical electrical competence and self-certification of electrical work under Building Regulations before you start searching for an electrician. It's the same but not necessarily the same.
The practical meaning of a Part P electrician
The term Part P electrician is an electrician who is able to complete electrical work in dwellings that need to be installed to meet Part P, which is the guidance on how the electrical work has to be designed, installed, inspected and tested, and the information that needs to be provided once the work has been completed.
An electrical safety check before home-energy work can also be beneficial for homeowners who are planning other major electrical projects like solar. Planned equipment may be safely connected or not due to the existence of wiring, circuits, and the consumer unit.
Compliance under Part P is thus not about certifying a specific solar panel, inverter or battery.
Competent Person Scheme registration and self-certification
The electrician must be registered to a recognised Competent Person Scheme in order to be able to self certify certain types of Building Regulations work rather than the homeowner make a separate application for Building Regulations approval. The scheme operator carries out an evaluation of members against the competence requirements and maintains monitoring of their work.
Once the work requiring notification has been qualified, the registered installer may make arrangements for the required Building Regulations compliance documentation. This will lower the homeowner's administrative burden as the installer will deal with the notification via the approved scheme.
The key difference lies in the fact that Part P registered electrician is not only someone who knows how to do electrical work, but also someone who is self-certified to do electrical work.
Differences between a qualified electrician and a Part P registered electrician
The practical experience of a person coupled with electrical qualifications may not qualify them to be registered under a Competent Person Scheme for the specific domestic work they are doing. On the other hand, registration of a scheme means that the electrician or business has been evaluated for the work that falls within the scope of the particular scheme.
This distinction will impact the way notifiable work is handled for homeowners. With the appropriate registered electrician it may be possible to self-certify the work, but if an electrician is not on a relevant scheme, then Building Control approval or another method of compliance may need to be obtained separately.
Hence, it is especially crucial to check registration prior to hiring major electrical home repairs. The next step is to know what domestic jobs involve Part P compliance and notification.
Domestic Jobs Where Part P Compliance Matters
Part P is for the safety of fixed electrical installations in dwellings, but not all electrical work requires notification to Building Control. The difference is significant when considering a larger upgrade as new circuits, alteration work to consumer-unit and some alterations may require a formal compliance path whereas some repairs may not be notifiable.
New circuits and consumer unit work handled by an electrician Part P registered
Installing a new electrical circuit or replacing a consumer unit is notifiable work under Part P and using an Electrician Part P registered via an authorised Competent Person Scheme can make the process easier, as the electrician will be able to self-certify work if it is eligible and set up the Building Regulations notification.
These jobs have significance because they relate to the main electrical wiring in the house, and not just the replacement of an existing fitting. They can occur where extra capacity is required for significant items of home energy equipment, or where an old consumer unit must be upgraded before new technology is installed.
Electrical alterations in areas covered by Part P notification rules
Part P makes a distinction between simple minor electrical work and changes that need to be noticed. In England, changes to existing circuits in a special location (such as some changes around a bath or shower) may be notifiable additions or alterations, and routine replacements and some minor alterations are treated differently.
Homeowners should not assume that the scope of the notification rules in Wales are the same as in England and should check the requirements that apply to the location of the property for Wales.
The basic rule is still the same. Even if the work is not notifiable, it still needs to be performed safely with all the electrical requirements being adhered to.
Fixed wiring for solar, battery and other home-energy installations
There may be new fixed wiring, protective devices or circuits on the electrical aspect of these projects, and this must be taken into account separately from the product itself for solar PV, battery storage, EV chargers and heat pumps. The domestic wiring will need to comply with the relevant Electrical-safety Rules, whilst a battery or solar system may have its own renewable-energy and DNO requirements.
For homeowners, planning solar panels and battery storage as a home energy system provides useful background on how generation and storage interact before the electrical installation is designed.
A Part P electrician who has previous experience in solar and/or battery installations can determine if the existing circuits and consumer units are appropriate, locate where new fixed wiring may be required and ensure it is installed correctly, following the correct notification path. As home-energy installations get more complicated, specialist experience is becoming more relevant.
Finding and Verifying a Part P Registered Electrician
After you know the kind of work, you need to select an electrician that has a registration for it and has experience in this field. Homeowners should not just take for granted that a company is Part P qualified, but should verify current registration before undertaking major electrical work.
Searching for a Part P registered electrician near me
When looking for a Part P registered electrician near me, a good place to begin is the Registered Competent Person Electrical directory. It enables homeowners to look up registered electricians with the code they enter for installation or remedial electrical work.
A local search will give a number of options, and homeowners should not just look for proximity or price. An electrician should have experience with the type of work they are doing, especially if it's an upgrade to a consumer-unit, solar PV or battery storage, or other high-load home-energy technology.
When dealing with a large project, it can be helpful to find out from a potential electrician what kind of work they have done recently that is similar to the system you are proposing.
Official checks to confirm an electrician Part P registered status
Homeowners can use the Electrical Competent Person Register before hiring a contractor, as they can conduct a search either by postcode or company name. The UK government specifically tells consumers who want to find a UK electrician that this is the register they should look at, as well as details on government-recognized Competent Person Schemes.
Therefore, an electrician part p registered must be verifiable by the appropriate scheme and cannot just state that they are registered on a website, van or quotation. Registering also has a connection to specific types of work, so it makes good sense to verify that the contractor has the ability to self-certify the work that is to be commissioned.
The guidance, which was updated in 2026, states that government-approved Competent Person Schemes are the only way for any electrician to legally self-certify electrical work under Part P.
Experience, insurance and project suitability to assess before hiring
Registration is one important check, but it can't be the only one. Another factor to consider before hiring a Part P Electrician is:
experience with the specific type of domestic installation;
appropriate insurance for the work being undertaken;
whether testing, certification and Building Regulations notification are included;
familiarity with the equipment and electrical loads involved;
a written quotation clearly defining labour, materials and responsibilities.
For solar and battery installations, these tests are particularly crucial as the electrician might need to liaise with renewable-energy installers or other experts.
After an appropriate contractor has been identified, the focus can now move from finding a qualified contractor to finding out about the electrical condition of the property itself, how many circuits are available and what tests must be performed before the installation begins and the capacity of the consumer-unit.
Preparing for Electrical Work in Your Home
Once a suitable electrician has been selected, the focus should then be on the condition of the property and the work that is proposed. If a customer is considering installing new electrical equipment or home-energy equipment, a proper assessment before installation can determine which circuits are not suitable for installation, whether the consumer-unit capacity is limited or other issues that should be addressed.
Initial inspection and discussion with a Part P approved electrician
Prior to the project, a Part P registered electrician must determine what is being installed, the path of the new wiring, and if the project includes new circuits or changes to the existing electrical installation. Part P specifies that reasonable provision must be made when designing and installing electrical work to prevent fire and injury to persons.
Homeowners should also discuss any future changes in the works with the moving company if the project is a large one. For instance, the installation of solar panels, battery storage and an EV charger or a heat pump at a later stage could have an impact on circuits and available electrical capacity planning today.
The initial discussion should also include the identification of the proposed work as notifiable or not and what certificates would be issued upon completion of the work.
Electrical load, circuit and consumer-unit checks before installation
Before putting in any major electrical equipment, it is important that the electrician check and make sure that the current electrical setup works for the new one. This could include a check on circuit arrangements, protective devices, earthing/bonding, suitability and condition of cable, and the condition of the consumer unit.
The mere addition of service to an existing older wiring installation does not necessarily necessitate replacing the entire installation. Additions and alterations shall, however, be made in such a manner that the completed installation will be safe and meet the requirements herein.
This will be important for solar and battery installations, which have a fixed electrical installation that might mean new circuits, consumer unit protection requirements, etc.
Testing and safety checks carried out as work is completed
The safety of the electrical installation should not be assumed from the appearance of the installation but should be verified by inspection and tests. As noted in Approved Document P, the purpose of inspection and testing of electrical work is to ensure the design and installation, and its ability to be used, maintained and altered, is sufficient and safe.
Therefore, a Part P electrician should test the finished job and deliver the correct electrical documentation. It is important to note that the guidance also makes the point that non-notifiable electrical work must be designed, installed, inspected, tested and certified according to BS 7671.
That last one is related to the paperwork the homeowner should be expecting, as an Electrical Installation Certificate, Minor Electrical Installation Works Certificate, and Building Regulations compliance certificate serve different purposes.
Paperwork to Expect After the Electrical Work
Once installed, this is not the end. Homeowners should also be given the records of any electrical work, of how it has been tested, and of how Building Regulations compliance has been recorded, if applicable. The type and size of the job is a determining factor in what certificate will be awarded, not just whether the electrician is "Part P registered.
Electrical Installation Certificates for new or significantly altered circuits
An Electrical Installation Certificate (EIC) is required for a New Electrical Installation and for additions and alterations when one or more new circuits are added. The current IET model form also includes replacing a consumer-unit, or distribution-board, which can be applied to several significant changes to an existing installation.
The certificate documents design, construction, inspection/testing and circuit and testing results. It verifies that the work certified has been designed, constructed, inspected and tested to meet the requirements of BS 7671.
For homeowners, the EIC should be securely stored as it can be helpful to future electricians working on the property and can be useful when selling their home or when additional work is to be done on the electrical system.
Minor Electrical Installation Works Certificates for suitable smaller jobs
A Minor Electrical Installation Works Certificate, sometimes referred to as a Minor Works Certificate, is for smaller additions or alterations to the house that do not require a new circuit to be provided. The current IET guidance provides examples of adding a socket or lighting point to an existing circuit or lighting switch relocation.
It can also be used to replace appropriate equipment; however, it is not recommended for the replacement of consumer-unit equipment or more extensive installations. The appropriate inspection and testing should still be undertaken even if the work is minor before the certificate is issued. (IET Wiring Regulations)
This separation helps ensure no homeowner assumes that a minor new circuit that is added for solar, battery or other home-energy equipment requires just a Minor Works Certificate.
Building Regulations compliance documentation from a Part P certified electrician
If the work is notifiable and is undertaken through an authorised Competent Person Scheme, then the homeowner should also have proof that the work has been self-certified for Building Regulations. A registered installer will be able to inform the local authority on the homeowner's behalf and issue a compliance certificate within eight weeks of the process is complete.
This Building Regulations certificate is a different certificate from the EIC or Minor Works Certificate. The electrical certificate documents the design, installation and testing to BS 7671, and the Building Regulations documentation shows that the appropriate notification requirement has been addressed.
Homeowners should thus keep both types of documents in place, if applicable. This will help ensure the electrical work is documented and will be of great benefit if solar panels, battery storage or other significant electrical projects are added on to the property.
Using an Electrician Who Is Not Part P Registered
It is not a requirement for a competent electrician to be a member of a Competent Person Scheme in order to undertake domestic electrical work. But if the works are notifiable under Part P, the Building Regulations approval process will change and could mean that further administrative burden is placed on the homeowner in using a person who is not a self-certifier.
Building Control routes when using an electrician not Part P registered
If there is notifiable work in England and it is carried out by an electrician who is not Part P registered, then the project cannot rely on a Competent Person Scheme self-certification. However, the relevant Building Control route should normally be set up prior to the commencement of works. Advice from the Local Authority is that if any notifiable electrical work is carried out by a person who is not on a Competent Person Scheme, an application to the Building Regulations and a subsequent inspection or testing may be required.
There is also a third-party certification process in England for certifying compliance with the Building Regulations for some domestic electrical work carried out by a third party that is appropriately registered as a certifier. This is a different process to that of the initial electrician who did the work being personally registered to self-certify.
Therefore, it is better for homeowners to set out the certification path they plan to take rather than to work out the approval after the installation is finished.
Responsibility for demonstrating compliance with Building Regulations
Selecting a non Part P registered electrician does not exempt electrical work from having to meet Part P compliance, but rather offers a recognized way of meeting the compliance requirements without the need for a separate Building Control application.
If the self-certification option is not offered, homeowners should confirm:
who will submit any required Building Regulations application;
whether Building Control inspections need to be arranged;
who will perform the required electrical testing;
which electrical and Building Regulations certificates will be supplied afterwards.
Even if a qualified installer is not registered under a Part P self-certification scheme, a qualified installer is required to have the relevant BS 7671 electrical safety certification for the work that has been carried out. The Welsh Government guidance is similar, recognizing the difference between Electrical Certification and Competent Person Scheme registration.
Resolving missing or incomplete electrical certification after previous work
Homeowners may find they have problems if they realize that previous notifiable work has been undertaken without building regulations approval. Regularisation is the retrospective approval process for eligible unauthorized work, and it may be possible to apply to a local authority Building Control Body for regularisation in England.
Regularisation is not just a replacement certificate service. Before Building Control is satisfied the work complies, the relevant parts of the installation may need to be exposed, inspected, tested or remedial works may need to be undertaken. Only issued if relevant requirements have been met.
For this reason, it is a whole lot simpler to verify the certification path before the work is started than to repair the certification records at the end. It is even more crucial if the subsequent job is solar panels or energy storage in batteries, as the electrician will need to evaluate the condition of the current electrical system as well as the extra electrical requirements of the new home-energy system.
Professional Electrical Planning for Solar and Battery Storage
Knowing the electrical system of the home and the certification path, homeowners can then think about how the battery or solar and storage system will actually be connected. It is at this time that selection of appropriate equipment should be based—not precede—the electrical assessment. The type of system to be installed safely and practically depends on existing circuits, capacity of the consumer unit, type of inverter, and future household requirements.
Electrical assessment before connecting a home energy storage system
Installers should not take it for granted that all homes are ready for battery equipment and should perform a review of the existing electrical installation if they are considering a home energy storage installation. They can be consumer unit, earthing and bonding, protection devices, circuit capacity and proposed connections.
The electrician should also take into account the amount of energy that is consumed by the household and which appliances are likely to be running at the same time. If the electrical installation has not been designed specifically to accommodate the battery, an oversized or a poor selection of battery is of not much value. Homeowners can use a solar battery sizing guide to understand how consumption patterns, solar generation and desired backup duration affect storage capacity before discussing the final design with an installer.
Where new fixed circuits or substantial alterations are needed, the Part P electrician should establish the appropriate testing, certification and Building Regulations route before installation begins.
EcoFlow STREAM 5000 for households planning solar and storage together
For households that have not yet installed solar panels, EcoFlow STREAM 5000 provides a practical route for planning generation and storage as one coordinated home-energy project. Considering solar input, battery capacity and household electrical requirements together can make future system expansion easier than treating each component as a separate upgrade.
However, STREAM 5000 should be included in an installation compliant with the appropriate electrical, DNO, and renewable-energy requirements. The product is not a substitute for a competent system design or for compliance with Part P as appropriate.
EcoFlow STREAM 5000 AC for existing solar homes adding battery storage
Homes that already have rooftop PV need a different approach because the existing inverter, wiring and grid-connection arrangement must be considered before storage is added. EcoFlow STREAM 5000 AC is designed for this retrofit scenario, allowing households with solar already installed to add battery capacity without planning the entire PV system from the beginning.
When retrofitting, it is advisable to have a Part P registered electrician or other competent installer to determine if any additional circuits or consumer unit changes or protective equipment need to be installed. Existing solar documentation and DNO records should also be checked as adding storage will impact the interaction between the solar system and the household electrical installation, and the interaction between the system and the grid.
Professional electrical planning thus links the project compliance aspect to the actual decision for energy storage. The best way to go is to evaluate the property first, choose the appropriate equipment second and test and certify after the installation work is done.
Conclusion
Choosing a suitable Part P electrician isn't just a matter of finding a person who can perform the actual electrical job. Homeowners should also ask the electrician if they are on an authorized Competent Persons Scheme, if the proposed project is notifiable, and what certificates will be issued upon completion.
When considering larger domestic projects such as installing solar panels or battery storage solutions, the electrical condition of the property may need to be evaluated prior to determining the appropriate equipment. The safety and effectiveness of connecting a new system depends on the existing circuits, the capacity of the consumer unit, and the protection devices and fixed wiring.
Through the relevant scheme, the work completed by a Part P electrician can be self-certified, which can make Building Regulations compliance a lot easier. When an electrician is not registered, the homeowner may be required to obtain Building Control approval or other recognized certification pathway.
FAQs
Can homeowners check whether a Part P electrician is currently registered?
Yes. Homeowners can check an electrician through the Electrical Competent Person Register, which brings together electricians registered with authorized Competent Person Schemes. The UK govt specifically recommends using this register to find or verify electricians for domestic work.
It is worth checking the registration immediately before hiring because scheme membership is what enables eligible electricians to self-certify relevant Building Regulations work.
Does a Part P electrician need specialist experience for EV chargers or heat pumps?
Part P registration alone does not demonstrate specialist competence in every home-energy technology. For an EV charger, homeowners should look for an electrician familiar with chargepoint design, load assessment and relevant network requirements; government grant-supported installations can also require an OZEV-authorised installer.
Heat pumps have their own installation standards and specialist requirements, with MCS operating a dedicated certification framework for renewable technologies including heat pumps.
The safest approach is therefore to check both Part P registration and technology-specific experience.
What should homeowners do if they lose an Electrical Installation Certificate?
First contact the electrician or company that carried out the work, as an Electrical Installation Certificate can only be issued by the people responsible for the installation work it covers.
If the original cannot be recovered, a qualified electrician can inspect the present condition of the installation and, where appropriate, produce an Electrical Installation Condition Report (EICR). An EICR assesses the current installation but does not recreate the original EIC or prove precisely how previous work was completed.
Any associated Building Regulations documentation should also be checked separately with the relevant Competent Person Scheme or Building Control body.
Can home battery storage be installed in a property that already has solar panels?
Yes, adding battery storage to an existing solar installation is a common retrofit approach because surplus photovoltaic electricity can be stored and used later instead of being exported immediately. Battery systems connected to the grid still need the appropriate installer assessment and DNO registration process.
Before installation:
Review the existing solar inverter and its capacity.
Check the property's circuits and consumer unit.
Confirm how the new battery will interact with the DNO connection.
A properly planned retrofit allows storage to complement the existing solar system without assuming that the original electrical design will automatically suit the new equipment.
Can a battery storage system be installed in a home without solar panels?
Yes, battery storage without solar panels is possible because the battery can charge using electricity from the grid and then supply stored electricity later. This can be particularly useful alongside a time-of-use tariff where cheaper electricity is available during selected periods.
Homeowners considering this setup should:
compare grid tariffs before estimating potential savings;
choose capacity according to realistic household demand;
have the electrical installation assessed before connection.
If the property and system configuration is appropriate, the solar panels can be installed at a later stage, so that battery-only installation is just one starting point and not permanently separate.
