How to become a licensed gas or electricity company

Application steps for a gas or electricity licence in Great Britain

A detailed overview of the application process can be found in the guidance document and application regulations, below.

We also operate an alternative route to obtaining an electricity supply licence which we call Licence Lite - you can read more on this further down the page.

Consult the guidance documents and the application regulations

Prior to filling out the application form you must read our licence application guidance document. The guidance includes an outline of the criteria we use when deciding whether to grant a licence. The Application Regulations can be found here: 

You must send your signed application containing all the information and documentation as set out in the relevant application regulations together with payment of the fee. The application forms include information on the relevant fees that should accompany applications.

  2. Your submission is acknowledged and checked for completeness and payment

    We acknowledge receipt of your application as soon as reasonably practical. We then review the application for completeness and confirm receipt of payment for the application.

    If any information is missing, we require further information, or the payment has not cleared into our account we will inform you and request the further information or payment. If you fail to supply the missing material, your application will be cancelled.

    When your application is complete and we have received confirmation that your payment has cleared, we will write to confirm your application as ‘duly made’. 

  3. Once the application is made, you will be asked to complete and submit a notice of application

    Once your application is confirmed as duly made, you will need to publish an application notice within 10 working days. We will send a template notice for you to complete and sign.

    The notice must be published (on our website or your own) and remain accessible for at least 28 days to allow any representations to be made.

    In addition to the checks we make on your application, we consider any representations received in response to your notice. 

  4. Your licence will be granted, or refused, or you may be asked for further information

    We operate a tiered, risk-based application process. If the results of our checks are satisfactory and the notice period has expired your licence is likely to be issued. If the results are unsatisfactory or give rise to further questions, further information may be requested and your application may be processed through a higher tier (Tier 2).

    If we propose to refuse your licence application, reasons for this will be given to you. You will have the opportunity to make representations if you disagree with our proposal to refuse the application.

    Timeframes for reaching a decision on whether to grant or refuse licences can be found in the application guidance document. The process may take longer if further questions are necessary, or there is a delay in receiving information from you.

    Alongside your licence application, you should be in contact with the appropriate organisations in respect of the industry codes that you must comply with / become party to under the licence.

Licence Lite

Licence Lite is a way to apply for a licence to supply electricity and to get a direction which will relieve you from your obligation to directly fulfil Standard Licence Condition (SLC) 11.2

It aims to ease potential barriers faced by aspiring suppliers or distributed energy generators.

As a Licence Lite supplier, you’ll need to have robust alternative arrangements in place for a third party licensed supplier to manage your code compliance in these areas.

Who’s it for?

Both prospective and existing electricity supply licensees can apply for a Licence Lite (SLC 11.3) direction.

You can read more details of the Licence Lite policy, and how to apply, in our Licence Lite guidance publication.

Exemptions from requiring a licence

There are some instances when you will not need to apply for a licence. Exemptions can apply to individual cases or a class of activity and may be unconditional or subject to certain conditions including length of time.

The Gas Act 1986 and the Electricity Act 1989 allow the Secretary of State to make orders giving exemptions from the need to hold licences. This means that some activities that fall within the definitions of a licensable activity are, in fact, exempt from the need to hold licences.

We are unable to advise you on exemptions and recommend you consult the Gas Act 1986, the Electricity Act 1989, your legal counsel and the Department of Business, Energy and Industrial Strategy (DBEIS). You may wish to view examples of gas exemption orders and electricity exemption orders

Exceptions (gas only)

Schedule 2A of The Gas Act 1986 (as amended) sets out certain exceptions to the need to hold a licence. It is for the applicant to ascertain whether the proposed activity falls within the scope of an exception.

We cannot advise whether a person carrying on an activity or proposing to carry on an activity will be exempt or excepted from the requirement to hold a licence. 

Complying with the industry codes

The licences set out that the licensee must become party to and/or comply with certain industry codes. You will need to make contact with the appropriate organisations directly in order to sign up to the relevant industry codes.
