Not sure this 30 week allocation explains the timescale for the whole process. I spoke to the future pension team in March and paid my Gap years on 16th March. As advised l called back ten days later as my Gap payments were not showing on my records. They confirmed and emailed my payment confirmation through to the next team for processing. I was advised it would take up to 10 weeks to sort. I took my pension on my 66th birthday on 18th April on the lower amount. After 10 weeks l spoke to the NI team via a chat site and they confirmed my Gap payments in a matter of minutes and again advised the processing team. Tge payments then showed as complete on my NI records. They advised me to check again after 2 or 3 weeks to check my pension had been increased. After 15 weeks l again phoned the NI team and they again emailed my notification of payment to the processing team. I was then advised it could take up to another 29 weeks to process the increase in pension. So it now looks like it will take 29 the plus the 15 weeks already past. Around 44 weeks to complete the whole process. Possibly more than a year if l had not chased three times?
