As an update the client received the following info from Stripe.
thank you very much for contacting us, I will be more than glad to verify the minimum amount for the transactions in your country, I completely understand this is something really important to clarify and I will be doing my best to provide all the information.
After checking all the information, I was able to find that the minimum amount you can charge is based on the currency of your bank account. In your case, for charges in GBP, the minimum charge is £0.30. In this case, as you are telling me that you offer services for £0.01 we have the options for microtransactions, or in markets where microtransactions are not available, an alternative solution would be to batch together multiple transactions from the same customer and submit them as a single, larger charge, I will leave some links below so you can have a little more information and you can know which options fits better for you:
Batch multiple charges:

Microtransactions for Stripe:

Please, If you have any additional questions, doubts or if you want to verify the option to microtransactions, please, do not hesitate to write me back, I will be attentive to any additional message, I am only one email away and always will be more than glad to help you.
Thanks
David
