I am currently in Madeira (Portugal) and have made a few calls to local numbers in Madeira. I have been charged for these calls, but my understanding is that the calls should have been free/only come out of my minutes as if I were in the UK making calls to standard numbers in the UK. Please can someone confirm if I have misunderstood?

Technically speaking Madeira should be covered under the inclusive roaming, yes.
My only guess here could be that at some point whilst you’re there you have gone out of reach of any Maderia based mobile networks and have connected to potentially either a Maritime service or potentially one in Africa. This would only ever happen if perhaps you were either out on a boat, or potentially somewhere really remote in Madeira without local island signal.
If you have a cap on your account you can prevent any high outside of plan charges landing on your account through logging into your account and setting a cap there. When out on a boat or on a plane, be sure to turn off roaming to prevent any background data potentially happening from your phone trying to connect online.
