IUI in the uk

Ok so I was just wondering if any of u ladies are from the uk and if u know anything about how <a href="https://glowing.com/glow-fertility-program">iui</a> works over here? I read somewhere that u get 5 rounds free on the nhs....then I found somewhere else it says they don't offer it free to couples anymore, only couples with HIV. So I'm confused! Any comments would be a great help!
