Turned down a £15k higher paid job because of train fare and taxes

Just wanted to rant a little.

I had a job offer that’s £15k more than my current role. Amazing, right?! Well it’s 3 days a week from London which I was completely fine with.

However with the higher tax bracket this put me in and the cost of trains to and from London 3 days a week the £15k is completely gone. How insane is that?!

So I’m better off staying in a job that pays £15k less because taxes and train fares are so high in this country that it’s not financially beneficial whatsoever for me to take a higher paying role.

What. A. Joke.

EDIT:

As people are asking the train costs:

Return train ticket varies between £60-£70.

Tube travel to office is £7.

All day car park at initial station is £7.

So that £74-£84 a day. Let’s say £80.

£80 x 3 days a week is £240.

£240 x 47 weeks a year (allowing for weeks off) = £11,280 a year on train, tube and parking.

Yes there’s some season tickets but the saving is limited.
