I applied in February of 2023 with the CF83 form. I received correspondence approximately 11 months later (Jan 2024) asking for more information about my employment history since leaving the UK all those years ago. After sending on the requested information I got the go ahead to pay about 2 weeks ago. However, I have spent the last few weeks trying to get in touch with the future pensions service and then HMRC and hence trying to understand the mechanism for paying. I think I'm on the last leg. Average wait times were between 20 mins and 30 minutes to both services. They are very helpful when you get through. As it corresponds to 17 x2 years ( my wife is in a similar situation), I want to make sure that I transfer the right monies to the right people with the correct references...hence my original query to the forum. (Aside : I'm still a little confused why the Reference Field is available for a Euro transfer but disappears for a GB pounds transfer .... But maybe someone else on the forum has more experience with all things banking. But saying that, it's the step that everyone on this forum has to complete.... Paying the NIC contributions. Has anyone used BOI app to pay in Sterling and used the "Message to Payee" to store their NI number ?) If I can be of any more assistance, send a message.
