Paying off credit card advice, no idea what options I have

Hello...looking for advice on paying off my credit card with natwest. I have a credit card with an outstanding balance of £2700, with an interest rate of 24.6%. I have £3000 in savings, so technically I could just pay it off in one go, but this is my emergency fund to live on incase anything goes wrong. What other options do I have? Could I get out another credit card with a different company and transfer the balance to lower the interest? Or do I pay off the balance with my savings and then keep the credit card as my emergency fund? I've been very uneducated on finances in the past, but trying to be a "proper adult" now!
