Additional Permitted Subscriptions (APS)
We support limited Additional Permitted Subscriptions (APS), enabling a surviving spouse or civil partner to make additional ISA subscriptions following the death of their partner. Where this is funded from the deceased’s ISA held on our platform.
APS allows the surviving partner to subscribe up to the value of the deceased’s ISA at the date of death, in addition to their standard ISA allowance.
How APS works on our platform
APS can currently be supported only where both the deceased and the surviving partner hold their ISAs on our platform, with the APS subscription funded directly from the deceased’s ISA. This process is supported via manual workflow.
Other scenarios
APS cases funded from external sources, or involving ISAs held across different platforms, are not currently supported. We are actively exploring enhancements to extend this capability in future.
The APS entitlement arises on death and is not restricted to a single provider. Where a surviving spouse or civil partner chooses to use their APS with another ISA provider, this is outside the scope of our platform process and would be supported by the receiving provider in line with their APS arrangements.
What do you need to provide?
Before we can begin APS processing, all documentation must be submitted to Söderberg for review. This can be done by emailing us at servicecentre@soderbergpartners.com
APS cannot progress until all documents have been received and validated.
Required Documents
| Document | Details |
| Death certificate | Scanned original or scanned certified copy only. Photographs are not accepted. |
| Proof of authority | One of: Grant of Probate, Certificate of Confirmation, Letters of Administration, Small Estates Form. Scanned original or scanned certified copy only. |
| Executor/administrator instruction letter | Signed confirmation of the withdrawal or asset transfer instructions, explicitly referencing APS. |
| APS Eligibility Declaration | Completed and signed. |
| Marriage or civil partnership certificate | Must evidence the relationship between the deceased and APS recipient. |
If any item is missing or incomplete, we will be unable to process the APS until it has been received.
What happens next?
Once this has all been received by our Service Centre Team, we will then pass this onto our back office for processing and they will arrange the transfer of assets from the deceased partners account to the surviving partners.
This transfer will not be counted as part of the clients ISA subscription but we will record the APS amount used for regulatory purposes.
The transfer will then show under the 'Report' section in the clients dashboard.
