Would I have more disposable income if I worked from home?

I spend nearly £400 a month commuting into work. We do get good Christmas bonuses though but on a month-month basis almost half of my salary is gone on tax, student loan but also my commute! I was thinking I could do a WFH for less salary but have more income bevause I won’t be spending it on the train

Are you talking about doing the same job for less, or switching jobs to one that offers WFH?

There are certainly benefits to WFH when it comes to (not)commuting - saving on expenses; not having to worry about rail strikes / traffic jams etc; not having to travel in bad weather. You have to weigh these against any potential extra costs e.g. using your own heating/lighting/ energy while at home - not so bad in summer but could be an issue in winter. Also maybe using your own equipment - computer etc - unless supplied by your employer.

Also remember no big cafeteria or restaurant/ office birthday treats / catch-ups by the drinks machine etc

You can claim a WFH allowance to help offset some of the energy costs etc. See:- https://www.thetimes.co.uk/money-mentor/article/working-from-home-tax-relief/

Like your user name. So simple but good. I think the WFH allowance was only for covid? Isn't that right?
