Hi All
I'm a 33 year old engineering professional working in an Oil and gas sector as Area sales manager for a valve manufacturing company in UAE with 9 years of experience.

I want to enroll in an online MBA programme from reputed university in UK which can boost my career and possible relocation to UK on later stage.
My budget is 20k-30k GBP.

I have been following various threads in this forum regarding the universities and rankings .
Based on the preliminary research , I've shortlisted some universities as below.

1. Imperial College business school
2. Warwick Business school
3. RGU (Robert Gordon university (RGU)
4. Alliance Manchester business School
5. Durham university
6. University of Birmingham
7. Edinburgh Business School
8. CASS BUSINESS SCHOOL

ICBS & Warwick are really good but expensive ,Since I'm aware of the fact that renewable energy is the future, RGU seems to be good but its not listed in any of the ranking List not sure why.

Appreciate if you can shed some light on the same.

Regards

I would ignore EBS since Heriot Watt lacks international accredition. RGU isn't ranked because it specialises in oil and gas, be tnit is a serious player in that industry. 
Using Linked In, which of these schools has the most MBAs in your target employers in your target countries? 

Hi Duncan Thank you for the valuable response.Based on your advise ,I searched in linked-In and RGU turned out to have most MBA's in the targeted countries (UAE& UK) in Oil& energy sector followed by Imperial ,warwick Manchester ,Cass & strathclyde Respectively.

All of them are good schools.
