Cancellation/refund for booking made with BA companion voucher plus cash

[ECO]

Hi, We made a booking for two people a long haul BA flight using a companion voucher and part points/ part cash (as we did not have enough Avios to pay for the whole thing with points). (£1181.92 was paid in cash, so not just the taxes.) We need to cancel. Do you know whether we will get a refund of the cash part of the booking? (We know that we will get the points and companion voucher back.)

Yes minus £35pp.

Also, when you go through the cancellation process online, you are told the exact amount of avios and cash you will get back.
