Thanks for the clarification! So from what I understand, you would like your domain "winchesterbookkeeping.co.uk" to point to your WordPress.com blog. Is that correct?
To make that possible, I would give Godaddy another call and ask for your domain's name servers to be changed to:
Or if you would like to do it yourself, please refer to this support page on Godaddy.
Then, I would purchase a domain mapping upgrade. This allows you to connect the domain to your blog. To get started, click on Store -> My Domains in your blog dashboard:
And click on "Map a Domain You Already Own". On the following page, enter the domain "winchesterbookkeeping.co.uk" in the URL field and click "Go". Please proceed with the succeeding prompts to complete the purchase.
For full instructions on domain mapping, please see our support page:
Let me know if you get lost along the way and need any further assistance. Thank you and best of luck!
