My experience is limited but if you are registered on the Gov Gateway site HMRC will transfer tax refunds directly (and instantly) to your nominated UK account. You may be able to register a Spanish account to receive it, but I doubt it.
You may already transfer funds from your UK account to Spanish account electronically, which with my UK bank is a bit of a fag but relatively easy, although as a consequence of leaving the EU Brits may have to pay a transfer receiving fee at the Spanish bank end.
You may have negotiated with your bank to minimize their fees but I tend to keep the account balance in Spain at a minimum due to any risk of Embargo charges (it does happen) and the management charges applied by Spanish banks.
You are likely already aware of all this but something may help.
