C1 - awaiting NS&I figure

jacklia

NS&I have told me it will be another month before they respond to my initial notification of Mum’s death which I did online on 8 April 2026.

I have all other figures for the C1, except the interest figure from NS&I on her fixed term bond up to the date of death. Is it permitted to put an estimated figure on the C1 for this (it’s easy enough to calculate) or should I wait another month for them to reply? We’re looking at less than £1,000 interest based on the bond value shown online at the date of death. IHT won’t apply.

I know NS&I will need the Grant of Confirmation to release the funds so would like to keep this moving if possible - but if I need to be patient, I’ll have to try 😊

This is an issue relative to Scottish Certificates of Confirmation because the probate/LOA system in England and Wales does not provide documents with an equivalent level of detail.

It is in line with the HMRC guidance (C3) to provide estimates rather than delay a Confirmation application. That said, I have no experience of the NS&I approach. Hopefully not an issue using an estimate.
