Can I do a master's in business administration (MBA) after completing my BCom degree in UK/Germany?

Yes, you can pursue an MBA after your BCom degree.

Your background in Banking, Insurance, Risk Management, and Taxation is a strong foundation for MBA programs. Most universities require a recognized bachelor’s degree, which you have. Some programs, especially in Germany and the UK, may also ask for work experience - your 12 years of experience is a significant advantage.

However, an 18-year gap since graduation is notable. You should be prepared to clearly explain this gap and highlight any relevant professional or educational activities during this time.
