Tax residency Cyprus / UK

Good day everyone,

I'm in the process of getting permanent residency via investment, and I'm migrating my business too.

I know that I can't spend LESS than 60 days in Cyprus a year and NO MORE than 183 days in any other state every year in order to keep my residence.

However, a friend has told me that I may be liable to pay my taxes in the UK, even if I spend per se 100 days per year, because I'm an British citizen. 

Is anyone in a similar situation or has had any clarification about the amount of time we may spend in the UK every year without raising any flags?

Thanks a million in advance!
