Is it allowed to have say 5 Adsense accounts linked to 5 different UK limited companies and bank accounts? I know its OK in the US but cant find an answer for the UK
If they are registered businesses and the cheques/EFT's are payed out to each different company then I don't think there would be a problem. However, just to be safe I would suggest you email Adsense support and ask them. They will be the only ones that can provide a 100% accurate and reliable answer.
It's okay as far as the payee names are different. Consulting google is always the best option available.
