Is it cheaper to live in UK or Korea?

I'm considering relocating to either the UK or Korea, and I'm trying to decide which country would be more cost-effective for me to live in. Could you please provide some insights on the cost of living in both countries? I'm particularly interested in the prices of accommodation, food, transportation, and utilities. Additionally, I'd like to know if there are any significant differences in the cost of daily living between urban and rural areas in these countries. Thank you for your help!
