Setting Home Page Name

I have an existing website, built using Serif, which has the home page of https://www.oxfordshiresevens.co.uk. I have built a new site using WordPress and wish to replace the old site with the new version. So that I do not lose traffic, I want the new site to have the same home page address as the current site. However, WordPress automatically uses the page name as part of the address and I am getting https://www.oxfordshiresevens.co.uk/welcome-to-oxfordshire-sevens as the default home page name, even if I try to edit the link.

How can I set the home page to be simply https://www.oxfordshiresevens.co.uk?

Thank you.

James.
