ILR FP same day service?

Hi all and thank you for your help in advance. Im applying for my second extension. Unfortunately, I had a lot going on in my family this past year and didn't realize my visa expires on February the 20th. I remember last time I paid for a service where my application was reviewed on the day and the visa was issued. Does anyone know how I can book this. I think it's £800 but I cannot find the number anywhere

Hi,

The priority service does cost £800
