Hi mate, you'll be fine on that. You probably won't save a huge amount but you'll definitely be comfortable here, be able to go out a bit and try some activities, and be moderately social. Providing you don't buy tons of clothes/tech (which are pricey here) and rely on expensive hotel meals, along with learning how to shop effectively - you will be fine. You'll be more comfortable than a 20k salary in the UK by a long way.
