Base pay is £34,440, rising to £41,328 with the 20% unsocial hours allowance and £43,562 on a 39-hour contract with pensionable additional committed hours.
On £41,328, take-home is about £2,623 a month. This is the salary level where the alpha pension contribution steps up: pensionable pay above £36,199 moves you from the 4.60% tier to 5.45%, so a Band 4 with unsocial hours pays the higher rate.
