First Great Western have decided that if you want a cash refund it will be at the rates published in the National Rail Conditions of Carriage. If you opt for Rail Travel Vouchers it will be at the rates published in their Passenger's Charter. By my reckoning that means:
High Speed Services If you are delayed by more than an hour on a long distance service you can have 100% of the cost of your single ticket in RTVs or 50% in RTVs if it's a return ticket. If you want cash it's 50% of the cost of a single ticket and 50% of the cost of the relevant portion of a return ticket. That means 25% of the price paid for a return ticket.
London & Thames Valley On
LTV▸ services you can get compensation in RTVs that is 50% of the cost of your ticket (single or return) if your journey is of an hour or more and you are delayed by an hour or more, or if your journey is less than an hour and you are delayed by over 30 minutes. If you want cash, as per the
NRCoC▸ , your delay has to be over an hour regardless of scheduled journey length and it's 50% of the cost of a single ticket and 50% of the cost of the relevant portion of a return ticket. That means 25% of the price paid for a return ticket.
West Services On local and suburban services in the west, south west and south coast (former Wessex Trains), if your journey is delayed by more than an hour you can get compensation in RTVs to the value of 50% of the cost of your single ticket and 25% if a return ticket is held. You'll get the same if you want cash. If your journey is delayed in excess of two hours you can get compensation in RTVs for the full cost of your ticket, but if you want cash compensation for a two hour plus delay it'll only be 50% of a single, 25% of a return.
Compensation - payment method
As per our Passengers Charter compensation is paid in the form of Rail Travel Vouchers or via an e-voucher, which will show as a credit on your First Great Western online account, we will always ask which you prefer. From the 19th July 2015 passengers can also request to receive compensation in cash and this will be paid, via a cheque at the rate set down in the National Conditions of Carriage.

FGW▸ for making the compensation arrangements even more difficult and anti-passenger. Why couldn't you just match the cash compensation arrangement to those in your passenger charter? Oh, I see, because the NRCoC is less generous in most cases and it just isn't good customer service in your eyes to go above and beyond.
