Changing homepage

Hi all

i built a website in Weebly drag and drop, then decided wordpress would be better.

I installed wordpress onto my url, then created the new website, the issue is that my URL is still the weebly one, not the new one.

ketcopropertyservices.co.uk is the weebly one, how do i move the homepage from this to my new one? ketcopropertyservices.co.uk/welcome

I can no longer access the weebly clipboard either, so I need wordpress to override weebly somehow?1 but just not sure how to do it?

Any help would be greatly appreciated.

Thank you
