Are you receiving an error when you are entering a personal password to register? 

When registering, your personal password needs to be a combination of 6-12 characters and numbers. You will need to use this password each time to log on. Your personal password will be case sensitive.


Are you receiving an error when entering your email address to register with the website? 

Our technical support staff have found the following common problems with email addresses:-

  • Each member requires a unique email address. You cannot share your email address with someone who is already a member of Slimming World Online or LifelineOnline.
  • Make sure you don't miss the .com or from the end of your email address
  • Make sure you don't miss the @ symbol from your email address

Please double-check that you’ve entered your email address correctly. A typo or misplaced period could prevent you from receiving important information from us. (We do not pass these details on to anyone else.)


Have you visited Slimming World Online or LifelineOnline before?

You may have already registered with the website. Please click here to return to the start and then click on the 'log in' using your username and password.


Do you share your email address with another Slimming World member?  

If you share your email address and the person you share it with has already registered on our website, you will need to use a different email address. The website recognizes each member by their individual email addresses so it won’t let a second person register with the details. If you would like an email address specifically for the purposes of using Slimming World Online or LifelineOnline - Google ( and Hotmail ( both supply free e-mail addresses.

I keep getting a security message when I enter the website...


Are you receiving a security message about security certificates?

If you're using an older internet browser, you may see an error message before proceeding to the next page stating "cannot connect to an expired server certificate."

We would like to reassure all our visitors that our Security Certificate is still valid and any data you use to access the Slimming World websites and/or provide during your visit will be transferred and kept securely, as per our terms and conditions.

To avoid seeing this message on future visits, you can either:

  • upgrade your browser to the latest version. (If you are using Internet Explorer, click 'tools>windows update' to start the process)
  • go to to manually install the new VeriSign Class 3 PCA Root (expiring in 2028) into your browser


I can’t login in today and it just keeps taking me back to login page, can you help?



To help resolve this problem you may need to clear your temporary internet files, and here’s how to do it:

Clear your cache and cookies (temporary Internet files):
Most browsers store a temporary copy of every page you visit. Clearing your cache deletes those files and makes room for new ones. Follow the steps below to clear your cache - if your browser isn't listed, please visit the Help section on your browser provider's home page.

  • For Internet Explorer 8:
    Select "Tools" from the top of the page and then click "Delete Browsing History". Tick the items as shown below and then click delete. This may take a few minutes. Once finished, close your browser, re-open it, and then try accessing the site again.

    IE8 - deleting your browser's history.

  • For Internet Explorer 7:
    Select "Tools" from the top of the page, then "Internet Options" and then the "General" tab. Under "Browsing history ", click "Delete". In the Delete Files dialogue box, choose "Temporary Internet Files", "Cookies" and "History", as shown below. Please note that if this has not been done regularly, it may take several minutes. Once you have taken these steps, close your browser, re-open it, and try accessing the site again.

    IE7 - deleting your browser's history.

  • For Firefox/Mozilla:
    Select "Tools" from the top of the page, "Clear Recent History " and then in the dialog box, tick the appropriate boxes, as shown below, before clicking "Clear Now".

Internet security settings

Zone Alarm: If you have Zone Alarm or something similar, please select privacy>site list and uncheck the third party web bugs setting.

If these actions don’t help, it may be that your security software is affecting you accessing the website, so it could be worth you checking this with your security software provider. To check this, try logging on using another computer outside your home, for example a relative or friend’s, and if you can get on to the website this would show that it is your security software at home stopping you from accessing the site.

Try an alternative browser

Using an alternative browser could also help to solve the problem. The most commonly-used browser, which comes with Windows, is Internet Explorer. However, there are a couple of other browsers which you can download and use for free. Just search for 'Google Chrome' or 'Mozilla Firefox'. Both of these browsers can be downloaded and installed relatively quickly, and may help you to get onto our site if the other solutions are not working for you.
