Still seems to be true, even within countries the discrepancy is pretty bad. They give the formula, but don't have a calculator, but you can use their "Move" calculator to estimate it:

Someone in London who is on £60k would get £35k if they moved to Bristol, or £30k in Brighton. Definitely a lot lower than market rates.
