OK, this may be a shot in the dark but here goes.

I live and work in the UK. I have been off work Thurs, Fri, Mon and Tues. The head of HR has heard that I have been off ill and said that as it's 3 continuous working days that I need a doctors cert. Thats in the company's policy handbook.
UK law actually says a 'fit note' is only required for more than 7 days continuous sickness, which includes non work days (Sat and Sun). So I've not yet hit that, but doesn't UK employment law trump and company policy?

I believe I don't legally require a sick note and that I can self certify. Does anyone know my rights?

I am genuinely ill. I was given a prescription by my doctor yesterday. Then had a flare up of my condition in the early hours of this morning.
