Prepayment British Gas vouchers only Post Office?

Update: Been on live chat, said the October voucher has epxired are they able to re-issue, voucher number given and put in a request to re-issue.

British Gas site states the key can hold £255 max, so going to take November, December and January vouchers tomorrow and redeem them - not sure why back in March it wouldn't hold more than £99.

Previously everyone seemed to be under the impression that the keys can only hold £49 or £50. I've alway been able to add £100+ onto my key but it was added by the PO in multiple transactions under £50. When I added my 3 vouchers last month it was added as £99 + £99 + £1(!) Maybe £99 is the single transaction limit - maybe £49 is the PayPoint self service machine limit??

I've heard of people adding more than £255 to their key - the problem then would be getting it off the key onto the meter because my meter at least will definetly not hold more than £255 (or maybe it's £255.99 or something). The meter has to have enough "room" before it will accept the credit from the key.
