Until now I have always worked near my home in the South of England, currently for a salary somewhere between 35 and £40k. There is the possibility of a move to London, for which the initial suggestion is around £50k. That headline figure sounds like a nice bump, but of course I have to offset travel costs (currently negligible for my nearby office) and I will also lose an additional two hours of my day commuting. I'm settled in my current town and don't have any serious intention of moving.
To help me consider the offer, I want to split out the increase into three headings - direct cash cost of working in London instead of locally, an element of "compensation" for the irritating commute, and the remainder (if any!) as a simple pay rise for doing a "higher level" job.
Can anyone here help me put a figure on these? Obviously the second category is extremely fuzzy, but I'd be grateful for your thoughts. Hopefully the first is simple enough. The third is then up to me to base my decision on.
Note that this pay rise would take me into the Higher tax band, so it's not a simple linear increase.
(Apologies if this is the wrong SE; I found a similar but not identical question here so thought this would be in scope.)
Thanks for your help.
