A prepaid certificate wouldn't work for me. I typically order my inhaler once every 6 weeks. It can be once a month, or it can stretch as long as two months. If I order one too early because I'm going away and need a spare, I can go as long as 3 months before needing to order one again, but on average, it's once every 6 weeks. A prepaid cert would cost me more in the longrun and I'm trying to reduce my outgoings, not increase them.
This thread was more about sufferers in general than me specifically, and research has been done by asthma charities into why people aren't using the prepaid cert.
The biggest reason is a lack of knowledge. Most sufferers report that it can take more than 6 months from being diagnosed with a chronic condition to being made aware of the prepaid certs, with a big chunk of people only learning about it all because of the questionnaire asking why they don't use it.
The second biggest reason is an inability to save to pay outright and a reluctance to set up a new direct debit. I can understand this. If your income varies due to zero-hour contracts, and you're living month to month, it can be difficult or impossible to make sure you have enough in your bank to cover your direct debits, and failed direct debits lead to bank charges, which lead to more failed direct debits or being unable to top up your gas meter that week.
The last reason was the same reason I have for not using one, an inability to predict how bad their condition will be that month, and whether a prepaid cert will end up costing more.
The prepaid certs are a good idea. They need advertising more, but I can see how they work well for sufferers of chronic conditions who can afford them and know about them, but if 30% of people with a chronic condition still need to ration medication, it's not working.
And in the midst of a cost-of-living crisis, where there are threads every day from people whose outgoings are suddenly outstripping their income, I'm finding it hard to understand why so many on this thread are unable to conceive of a way where someone might not have a tenner left at the end of the month.
