HC1 applications, HC3 certificates, travel costs

Hi folks,

My Dad (recently retired pensioner) has sent away an HC1 application for health costs. He's really hoping for the help with travel costs, as he's being referred to London (from Glasgow) for a course of treatment on the NHS that isn't available anywhere closer, and will have to make several journeys.

1. Are HC1 applications ever rejected out of hand? I can't find any examples on here of people who have been turned down completely, so I was wondering if the "worst" result possible was just an HC3 certificate with rather high limits on what people have to contribute themselves towards health costs.

2. Of the people who receive an HC3 certificate, what amount did they say you had to contribute towards travel costs per week (if you don't mind sharing)? I'm trying to work out if there's a "standard" upper limit.

Many thanks!

John
