Not that it makes much difference but the aircraft is in Spain and flight-plans will be required.
It makes a huge difference, as air law in Spain is not the same as air law in the UK.
I've not flown in Spain without a flight plan, but didn't think that was the law so much as the local requirement at some airports? In any case, as I'm certainly not an expert in Spanish air law (and nor I suspect are most other people posting on here) I think that getting local advice might be a really good idea.
It's a good working assumption that when flying a G-reg outside the UK, basically the most restrictive of the state of registration permissions, and local permissions, apply. If there's uncertainty about that, you need more expert advice than a bunch of us on an internet forum.
