There are lots of different funding bands for apprenticeships. Even within a particular industry you can have the full range of funding bands. The maximum amount of funding you can receive for a single apprenticeship is £27,000.
However, the funding bands are relative to the usual costs for that training. That means that whichever band the apprenticeship you want to choose has is unlikely to effect the end costs of your apprenticeship. The only time it is important is if you decide to purchase training for an amount above the funding band.
