According to the Bank Of England’s Inflation Calculator, UK inflation from Jan 2023 to October 2023 was 4.4%

Ignoring any further inflation until next January, and assuming you’re fortunate enough to be a higher rate taxpayer, if you want to just keep up with inflation, you’ll need a 7.5% payrise (to compensate for that which you lose to tax and NI). 

You need more than that to actually get ahead.
