I’m wondering if anyone has experience of their 16 year old taking control of their premium bonds account? I helped my son fill out the form and got a family friend to write the covering letter witnessing his signature. We sent it to them at the beginning of September. I thought we would have heard something by now? I tried calling them last week and they said it might be that they need more information like a passport or birth certificate but wait until we hear . Is it usual to take this long though? Starting to worry it’s got lost!
