EI membership runs from 1 January - 31 December each year. The due date is 1 January of the year for which you are reviewing, unless you pay by Direct debit, in which case your payment will be taken in February.

We offer half rate concessions on annual membership subscriptions for those who are in receipt of an income of less than £15,000 per year before tax, and local rates for pre professional members in Malaysia, Singapore and Nigeria. To request a concession for a particular subscription year, you will need to send us a formal declaration confirming that you meet the eligibility criteria before 1 January.

We also offer concessionary rates for those who are fully retired from energy. There is no need to reconfirm this every year - a one off declaration in the year you retire is sufficient.

If you would like to apply for a concession, please download and complete the application form and send it to membership@energyinst.org. Please note that concessions are discretionary and assessed by the EI on a case-by-case basis. Concessionary rates cannot be applied retrospectively.

Apply for a concession

Signing up for Direct Debit is the easiest way to ensure your membership fee is paid in time each year and your access to your member benefits is uninterrupted. To register, please complete and submit our direct debit form.

Alternatively, you can renew your membership by logging into your MyEI profile, clicking on ‘Renew membership’ and entering your card details. When you have paid, you will be able to download a receipt. Please also make sure to review your contact details and mailing preferences to ensure all your details are up-to-date.

If you are a UK taxpayer, then please Gift Aid your subscription by downloading this declaration form and sending it to us. You will be enabling the EI as a registered charity to make the most of your payment by claiming an additional tax back from HMRC. To find out more please read the FAQs.

You are welcome to apply for a higher grade of membership or add an additional professional registration at any time throughout the year. Applications from existing members and new members are treated the same, except for the special instances listed on each grade’s web page. To upgrade, visit the web page of the grade you wish to transfer to and follow the application instructions.
