Firstly - we'd hate to see you go & if there is anything we can do, please let us know.
If you really do wish to cancel your website, that's absolutely fine.
Just get in touch to let us know & we will cancel all future website hosting invoices for you (there is no cancellation fee either).
Your domain name is yours to keep if you still need it - again, let us know & we can transfer it to another registrar account for you.
If you don't need your domain name anymore - we won't renew the registration when it next becomes due.
While you can't take your website with you (the code is ours) - there is a function in the admin area of your website that allows you to export all of the text on your website at any time.
