Hello from Australia - this is a good news story! To all us long suffering ex-pats panicking about our UK state pension voluntary contributions - I actually got through!!! - albeit after a half hour wait. So I recently received my forecast and had sent off my CF83 'Application to pay National Insurance contributions abroad' form. I was just checking it had been received and yes it was in the system but was told the backlog is currently 43 weeks! However I was told not to worry, if your CF83 form is in their system, you will eventually receive a letter (in the post) advising how much to pay and you've then got a further 8 weeks to pay your contributions. So everything should get processed as usual but it'll be delayed by several months. Hope this helps.
