How do I log into my account for the first time?

To log in for the first time, you’ll need:

  • your Nest ID
  • your date of birth
  • your National Insurance number or alternate unique identifier

You can find your Nest ID in your welcome pack. It begins with MEM and contains nine numbers, for example MEM012345678. If you don’t have your Nest ID, you’ll need to call us on 0300 020 0090 so we can help you.

  • Visit our login page.
  • Enter your date of birth, Nest ID, and your National Insurance number or alternate unique identifier.

  • Click ‘Next’, then you'll be able to see the details provided to Nest by your employer.

  • You’ll need to provide your mobile number and email address.
  • Providing your contact details will allow you to log in with either a passcode sent to your UK mobile number or an activation link sent to your email.
  • Select how you would prefer Nest to contact you and click ‘Next’.

  • We’ll ask you to create a username, password and three security questions before verifying your account.
  • The security questions will help you to reset your login details if you forget them in future. You can find out more in our What are the security questions? article.
  • When you’ve finished creating your log in details and security questions, click ‘Next’ to verify your account.

One time passcode or email activation

  • We’ll text you the passcode and you’ll need to use it straightaway as it expires in 10 minutes.

  • If you didn’t receive a passcode, click ‘Get a new passcode’.
  • To update your mobile number, click ‘Change it now’.

  • You’ll need to select ‘Finish and get started’ to log in.

  • If your email address is correct, click ‘Send verification email’ to receive the activation link. The link expires after 28 days.

  • If you don’t receive an activation link within 24 hours, call our contact centre on 0300 020 0090.
  • The activation link, will take you to a page confirming that your online account has been set up. 
  • Click ‘Ready to start’ to log in.
  • If you haven’t followed this link to complete your account registration within 28 days since our email was sent, you’ll have to begin your registration again and re-enter your details online.
