Updating domain name in wordpress installation

I have just moved my site to a new host, but before I transfered the domain I set up the installation as https://87.117.196.179/~timeoutb/

The domain https://www.timeoutbookings.co.za has been transfered but the site still redirects the domain to https://87.117.196.179/~timeoutb/

How do I change the settings in wordpress to reflect the site as https://www.timeoutbookings.co.za
