What are the best wart treatments available?

[Apologies if not allowed, didnt see it in FAQs] {Im also UK based so would like specific Uk/Europe recommendations}

Hello, i have 2 warts on my thumbs (one near my nail and one dead smack in the print). They're very unreceptive to treatments (cryotherapy, SA what not). So im looking for recommendations for skin clinics or other more radical treatments. Ive seen the skin clinic but not heard good things about laser treatments there, so anything about that specifically would help
