Chances of landing a good masters at a target uni

Hey, I am a final year BSc Economics student at a semi-target Russell group uni. I completed a front office summer internship (sales and trading) at an investment bank last summer and have an upcoming private credit summer internship this summer at a buy-side firm. I have also been extensively involved in my university's economics and finance society holding some leadership positions. I was wondering what my chances of getting onto a good masters programme in King's/UCL are given I am just about making a 2:1 right now. Looking at computational finance and general finance/econ courses. Will my work experience make up for my weaker grades? Any help would be much appreciated!
