Will I get 30 days or 15 days upon re-entering Thailand with a UK passport after a 60-day tourist visa?

If you re-enter Thailand from Cambodia with a UK passport after your 60-day tourist visa has expired, you will typically receive a 30-day visa exemption at the border. However, the number of days granted can depend on various factors such as how many times you have entered Thailand in a short period. Generally, if you have just used a 60-day tourist visa, the 30-day exemption is standard, but there is a possibility you might be granted only 15 days if the immigration officers suspect frequent short visits. It's always best to be prepared with supporting documents to demonstrate your intentions.
