You also have the right to allocate personal allowance, basic rate tax bands, etc., in any order that benefits you. Usually, the "official" order is best for most average people, but there are unusual cases where someone may want the standard order changed to produce a lower tax bill, which is entirely their right and permitted by tax laws.
(Though you may have to be assertive with HMRC as far too many of their customer service advisors don't know you have the right and don't know how to do it at their end!!).
Won't make a difference to the OP with a wage and pension, but sometimes makes a big difference to people with foreign income upon which foreign tax has been paid, or a particular mix of different kinds of unearned income, such as dividends, or "top slicing relief" (again very specific and uncommon).
I've just done one with someone who had a mix of wages, dividends, foreign rental income and foreign tax paid on the foreign rental income - took me over a year to get HMRC to accept my claim to re-arrange the order of income, allowances and bandings, but I got there in the end - a few thousand tax repayment for the client, plus a few hundred compensation for the HMRC mistakes/delays in dealing with a perfectly legal request to change the order!
Just making the point on here for other people who may be reading this post with more complicated affairs.
