An Electrical Contract is a legally binding agreement between a client and an electrician or electrical contractor that sets out the terms on which electrical works will be designed, installed, tested, and certified. In England and Wales, electrical contracts are governed by the Supply of Goods and Services Act 1982 and, where the client is a consumer, the Consumer Rights Act 2015. These statutes imply that all services must be performed with reasonable care and skill, that any goods supplied must be of satisfactory quality and fit for purpose, and that the work must be carried out in accordance with all applicable laws and regulations.

Electrical work in England and Wales is subject to extensive regulatory oversight. The Electricity at Work Regulations 1989, made under the Health and Safety at Work etc. Act 1974, require that all electrical systems are constructed so as to prevent danger and that all electrical work is carried out safely. All electrical installations must be designed, installed, and tested in accordance with BS 7671 (Requirements for Electrical Installations, IET Wiring Regulations), which is the national standard for electrical installations in the United Kingdom and is currently in its 18th edition.

For residential properties in England and Wales, Part P of the Building Regulations 2010 requires that notifiable electrical work meets safety standards and is either carried out by a registered competent person or notified to the local authority building control. Notifiable work includes the installation of a new circuit from the consumer unit, replacement of a consumer unit, and work in special locations such as bathrooms. An electrician registered with an approved competent person scheme (such as NICEIC, NAPIT, or ELECSA) can self-certify their work and issue a Building Regulations Compliance Certificate, also known as a Part P certificate, directly to the homeowner.

A written electrical contract provides both the client and the electrician with certainty about the scope of works, the price, the programme, and the documentation to be provided on completion. For the client, the contract should establish the electrician’s obligations to comply with Part P, to carry out the works in accordance with BS 7671, to provide all required test certificates and inspection documents, and to remedy any defects in the work within a defects liability period. For the electrician, the contract sets out the payment terms and provides protection against scope creep and delayed payment.

Electrical work is a regulated trade in England and Wales, and the consequences of poor or non-compliant work can be severe, including risk of fire, electric shock, and death. A well-drafted electrical contract provides an important framework for ensuring that all works are carried out to the required standard, by qualified and registered operatives, and that the client receives all necessary documentation to demonstrate compliance and to protect the value of their property.

A written Electrical Contract should be put in place before any significant electrical work commences. There are many situations in which a formal electrical contract is particularly important.

For major electrical installations, such as a full or partial rewire of a residential property, replacement of a consumer unit (fuse box), installation of a new circuit for a kitchen, bathroom, or garage, or installation of an EV charging point or solar panel system, a written contract is essential. These works are typically notifiable under Part P of the Building Regulations 2010, meaning the electrician must self-certify the work (if registered with a competent person scheme) or notify the local authority building control. A contract should make clear which party is responsible for compliance notifications and should require the electrician to provide all required certificates on completion.

For landlords in England and Wales, a written electrical contract is necessary for compliance with the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020, which require a valid Electrical Installation Condition Report (EICR) every five years and before the start of each new tenancy. The EICR must be carried out by a qualified and competent electrician, and a copy must be provided to the tenant and, on request, to the local housing authority. A contract with a qualified electrician ensures that the EICR is carried out by a competent person and provides a record of the landlord’s compliance.

For commercial clients, a written electrical contract is essential when engaging an electrical contractor to carry out works on commercial premises. The Electricity at Work Regulations 1989 impose duties on employers to ensure that electrical systems on their premises are maintained in a safe condition. A contract with a qualified electrical contractor helps to discharge these duties and provides a framework for regular inspection and maintenance.

An electrical contract is also important when the work involves emerging technologies such as EV charging points, solar photovoltaic systems, battery storage systems, or smart home installations. These technologies are subject to additional regulatory requirements beyond the core BS 7671 and Part P regime, and a well-drafted contract should address the specific standards and certifications applicable to the technology being installed.

A well-drafted Electrical Contract for use in England and Wales should include the following key provisions to protect both the client and the electrician.

The scope of works clause should provide a detailed description of all the electrical works to be carried out, including all circuits to be installed or modified, the specification of the consumer unit or distribution board, the cable types and sizes to be used, and any testing to be carried out. The clause should also identify works that are excluded from the contract price (such as making good plaster or decoration after the works, or works to be carried out by other trades).

The regulatory compliance clause is one of the most important elements of an electrical contract. It should confirm that the works will be carried out in accordance with the current edition of BS 7671, the Electricity at Work Regulations 1989, and Part P of the Building Regulations 2010 (where applicable). The clause should specify the competent person scheme with which the electrician is registered and the electrician’s registration number, so that the client can verify registration before the works commence.

The testing and certification clause should set out all the test certificates, inspection reports, and compliance documents that will be provided on completion of the works. At a minimum, the electrician should provide an Electrical Installation Certificate (EIC) with Schedules of Inspections and Test Results, and a Building Regulations Compliance Certificate (Part P certificate) for notifiable work in dwellings. The contract should make clear that final payment is conditional on receipt of all required documentation.

The price and payment clause should state the total contract price (inclusive or exclusive of VAT), the payment milestones, and the consequences of late payment. The defects liability clause should specify the period during which the electrician will remedy defects at no charge. The liability clause should address the electrician’s liability for damage and confirm insurance arrangements. Finally, the governing law clause should confirm England and Wales as the applicable jurisdiction.
