Temporary Electrical Systems (TES)

The Temporary Electrical Systems (TES) membership is designed to provide access to work in the entertainment industry and similar situations where a temporary electrical supply is needed.

There are a wide range of temporary installations including public or private events, touring shows, theatrical, radio, TV or film productions and similar activities of the entertainment industry. The knowledge, understanding and competence to work in this area is specialised and unique, while overlapping that for conventional electrical installation work. It is vital to the industry to know that the electrical contractors they appoint are competent and trained in the requirements of BS 7909.

Scheme Details

Geographical Scope – United Kingdom
Approval - Carried out under NAPIT's ISO 9001 Quality System

Scheme Requirements

The following general conditions must be met:

Relevant Standards - members working on temporary electrical installations should do so in accordance with the current edition of BS 7909. This standard must be held together with any relevant guidance documents listed in the Requirements for Registration.

Legal Requirements - temporary electrical installations must comply with the Electricity at Work Regulations as well as other legislation including the Provision and Use of Work Equipment Regulations. These require competence and the Person Responsible within a BS 7909 is able to demonstrate that competence.

Qualifications - for the temporary electrical installations Scheme you or at least one person within your business must have completed training on BS 7909. There are two courses available from NAPIT Training: NA-7909-3 is a full course for those starting work in this area whereas NA-7909-1 is a refresher course for those already involved (and who is likely to have previously completed the Skillset Certificate in Temporary Electrical Systems (SCiTES). Please note other accredited temporary installation industry qualifications are accepted. See the NAPIT Guide to Qualifications – Electrical for lists of suitable qualifications which can be found on the NAPIT website.

Insurance - you must hold public liability insurance specific to the temporary electrical installation work to be undertaken, to a level evaluated by a suitably informed broker/insurer and meeting your client’s requirements. NAPIT requires a minimum of £2 million cover for basic temporary installation work but it should be recognised that this is unlikely to be sufficient for many contracts.

Instruments - you or your employees must have access to sufficient instruments to carry out tests specified in the scheme rules and BS 7909 as well as in date calibration certificates for this equipment where applicable.

Inspection - included in the NA-7909 course is an operative assessment. This is the initial assessment for registration provided evidence is provided for insurance and calibrated test equipment. The first surveillance will take place in the second year of registration and will cover business systems and records. If satisfactory surveillance will take place on a three year cycle as described in Requirements for Registration.

Website listing - Once successfully registered, your business will be added to the dedicated BS 7909 category of the NAPIT online search facility.


NAPIT Training offer two City & Guilds accredited training programmes which have been designed to enable the candidate to understand the principles of BS 7909 and its applications within temporary electrical systems.

The programme has been created for electricians looking to upskill and all of those working with temporary power, particularly (but not exclusively) in the broadcast/film, theatre, festivals, shows and exhibition industries. For more information on the training programmes please visit: www.napittraining.co.uk/.


The knowledge, understanding and competence to work in this area is specialised and unique, while overlapping that for conventional electrical installation work.

If you already have EAS you will still need to complete the training and assessment described above to register for temporary electrical installation work. As a qualified electrician you may be well placed to work as a subcontractor to an organisation with BS 7909 approval. If you join the BS 7909 scheme in addition to EAS you will be eligible to have EAS scope A1.3 added to your certification.

If you are joining NAPIT purely for the BS 7909 scheme you will not be able to join EAS without achieving the qualifications required by EAS and undergoing assessment to demonstrate competence.
