I am looking for some career advice on a potentially expensive career change decision. My current situation is as follows:
I’m 32 and I work in a technical job in the pharmaceutical industry in the UK. My university education was in Chemistry – I have a bachelor’s degree. My current salary is £32,000 a year and I live in one of the cheapest parts of the UK - my salary is well above the median. I am comfortable and do not wish to retire before 50 (that’s what I consider early retirement ^^ ).
I contribute 7% of my salary to my pension, to which my employer adds 7%. I have a small mortgage remaining on my house of approximately £48,000 and my monthly payment is around £200. And I have no plans to move, ever. At present I save 50% of my take-home pay (my take-home pay is £1900/month) and use this money to over-pay my mortgage. Other than my pension (which has around £50k in it), I have no liquid investments.
My question, or rather problem, is this: I have reached a ceiling in my job/career – I cannot increase my salary beyond what I currently earn, and I no longer feel challenged in my day-to-day work. A couple of years ago I decided to try and change direction, and further my education by enrolling in a general engineering bachelor’s degree part-time, which my employer generously agreed to pay for (100%). They agreed to do this because my current role in the company has a basis in engineering.
I have completed 50% of the degree and I am a bit disappointed

I now have the option of switching to another university and transferring all my credits to graduate with a bachelor’s degree in chemical engineering instead of general engineering. The problem is that the new university course is much, much more expensive. It’s a one-of-a-kind course and there is no other like it that exists in the UK.
My company will only contribute some of the money, leaving me to stump up £13,500 over 3 years to finish the course part-time.
I have no debts and I could afford it on paper. What should I do?
I am confident that through this course I can eventually get a better paying job that would recoup the £13,500, and some, but my worry is that I won’t graduate until I’m nearly 36 years old and by that time perhaps I won’t have as much energy and enthusiasm as I have now.
I should also point out that I am not so confident that I can get a good engineering job with the general engineering degree that I'm currently doing, and I feel that it doesn't have that much value.
Thanks for reading this,
Garbo
