It may be possible to do a second apprenticeship. Below you can find the government guidelines surrounding the subject:
P59. Any qualified individual can be sponsored to undertake one at a higher level than the one they currently hold, even though they have already held one.
P60. We will fund an apprentice to perform one at the same or lower level than their existing credential if it would enable the pupil to learn substantive new skills.
The apprenticeship is at the same or lower level than prior qualifications, evidence that the apprenticeship leads to substantive new skills and that the learning is materially different.
