Load Bearing or Not?? How do I know

[nellymcl]

Good Morning all
I am looking to double the opening from my kitchen to my dining room, removing the door and making it an 'arch'. How can I tell if the wall is loadbearing or not?
My house is a mid 1960 Bett semi with brick walls downstairs and stud walls upstairs and there is no wall directly above the the kitchen and dining room dividing wall.

Cheers

Do the floor joists on first floor above bear onto the wall?

The upstairs joists run perpindicular to the wall

Then they run onto the wall thus its load bearing
