How do you prove that you never received a letter?!
If the letter is on the system and it is dated then it's fair enough to assume you have received it royal mail don't fail to deliver on 9 out of 10 occasions. If you are expecting an appointment, and don't receive a letter, you can ring to find out the info. If a letter isn't on a system, it's also fair to assume it hasn't gone out.
The sort of admin error that I am thinking of is admin staff putting the wrong dates for surgery etc on letters. I know people that this has happened to, and it ends up costing the NHS thousands.
It's not exactly hard to charge people £15 an appointment
I work full time and pay my taxes. I also have a chronic medical condition. Whilst I was being diagnosed, I was going to the GP weekly for 6 months. Why is it remotely fair that I would have had to pay £360 during those 6 months for my appointments, plus my tax deductions, plus my prescriptions, when I haven't elected to have an uncurable condition? I will have to go in the future, too.
When I'm not working full time, which will be soon as we are expecting, we will be cutting down hard on finances as my husbands income will be our only income when I'm on maternity leave (I'll get SMP), after that I'll go part time as we simply can't afford childcare 5 days a week. My husband isn't on a particularly high wage, but we won't be entitled to benefits, and will get by one way or another.
Why is that fair? If you work, you put money in to the system and are already entitled to a lot less (obviously) e.g. no help with childcare costs until kids are 3. Why penalise working people even more?
I'm in no way slating those that don't work and do claim benefits - we all have reasons that might mean we fall on hard times or can't work for various reasons, but it would just be another nail in the 'reasons you are better off not in work' coffin.
So in short....just £15 for an appointment really isn't a small amount.
