Hull online MBA cost only 12k GBP and is AACSB/AMBA accredited. I was looking at University of Birmingham but it’s almost double the price. Is this the best value for an online MBA from the UK that’s double accredited? I’m open to other suggestions. I’m looking for a solid programme, doesn’t need to be top ranked but should be rigorous.

I'm not sure what you think the value is. The value would normally be the net present value of an option. In that context, the best value would be a higher-than-average return on your investment. The Hull online MBA certainly is among the cheapest option with its low-cost base (the module leader and tutors seem to be external professionals rather than academics in the UK). However, if you had a *career* goal then the best value would probably come from a bigger investment. There are other options at https://findmbaonline.com/board/general-forum/value-alternatives-to-unaccredited-mbas-58288   including the triple crown OUBS MBA for $9000
