The replies you have gotten so far have been US orientated and vastly overestimate salaries here in the UK. Especially the UK outside of London.

Assuming you are in Cardiff, possibly Newport, a starting salary for a graduate is around £21,000 - £25,000. With your experience however I'd expect that £25,000 - £35,000 isn't impossible if the company wants a strong Angular dev.

My advice is that you should move to the South East of England, if it's feasible, salaries are way higher than the rest of the country.
