Holiday entitlement when self entitled

Amanaman

For the last 4 years, I have been working from home in the UK as a freelance writer for a company based in Israel. I am paid per article and I pay my own income tax and national insurance so I am registered as self employed ,despite not running my own business. 

I currently receive 10 days paid holiday per year but don't have a written contract.A I entitled to any more days holiday per year since I work full time hours and don't work for any other company? I also haven't had a pay rise since I joined. Am I entitled to a cost of living rise? It feels like I am a full time employee with freelancers rights. Any advice would be appreciated.
