Delay Repay Question

[Southern Beau]

My father purchased a GWR advance single ticket (price on ticket was £38.50) using a rail voucher at his local station.

He was delayed for 40 mins.
Although he did not part with cash, I presume he is entitled to submit a delay repay claim?
And would he expect to receive 50% of the value of ticket (ie: £16.25)?

Yes.

Not quite! 50% of £38.50 is £19.25.
