UK only please

Has anyone from Uk had <a href="https://glowing.com/glow-fertility-program">ivf</a> or <a href="https://glowing.com/glow-fertility-program">IUI</a> in privet clinic but had some sort of payment plan I’m waiting for my first appointment which is next week but I’m worried that it’s going to be a bit out of our reach and was hoping there’s some way we could pay like 50% then rest on on like a payment plan but waiting for this appointment is killing me.
