Renew your membership

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

Direct Debit

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.

Gift Aid

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.

Upgrade your membership

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.
