If you’re unsure about a letter from this PO Box, or simply curious, this guide will offer all the details you need to make informed decisions. Let’s take a closer look at what this address really means for you.
What Is PO Box 1550 Salisbury SP1 2TW?

PO Box 1550 Salisbury SP1 2TW is a registered mailing address primarily used by Aviva Life & Pensions UK Limited. It is not a walk-in location or physical office but rather a secure postal handling service. This kind of setup is commonly used by large financial institutions to centralise their inbound mail and route it efficiently to the appropriate departments.
Companies like Aviva use PO Boxes for various customer interactions, including managing pension policies, retirement plans, and other life assurance services.
These services require secure and traceable communication, which a PO Box can efficiently handle. In this case, all post directed to customers of specific pension plans, like those transitioned from NCS Services or DNB Pension Plan, are channelled through this address.
This PO Box is situated in Salisbury, Wiltshire, and is associated with sensitive documentation like pension certificates and policy updates. That’s why only verified providers and organisations are permitted to use this address.
Why Are You Receiving Mail from PO Box 1550?
You may be receiving letters from PO Box 1550 if you have previously been a part of a pension or retirement scheme now managed by Aviva. After several older pension plans were wound up or restructured, individual policies were created and transferred to Aviva, with ongoing communication sent through this Salisbury PO Box.
Typical reasons for receiving this mail include:
- Updates or changes to your pension policy
- Confirmation of pension transfer or buy-out
- Requests for additional information or verification
- Annual summaries or financial statements
If you’ve ever worked for companies that used third-party pension services like Pearson Services Limited, which once sponsored the NCS Retirement Benefits Plan, you could be listed as a plan member.
After the plan’s wind-up in 2021, members were automatically issued Aviva policies, and all communication was rerouted through PO Box 1550.
Make sure to carefully read any letters from this address and compare them with your pension or life insurance history to confirm their relevance.
Could It Be Related to Your Pension or Retirement Plan?
Yes, receiving mail from PO Box 1550 Salisbury is highly likely to be related to your pension or retirement plan. This is particularly true if you were previously a member of the NCS Services Retirement Benefits Plan or any similar scheme that has since been transitioned under Aviva’s management.
For example, in 2020, following a decision by the sponsoring employer Pearson Services Limited, the entire NCS Plan was moved from Utmost Life to Aviva. After the assets were successfully transferred in October 2020, Aviva took over the responsibility of issuing individual pension policies to all affected members. These policies are managed through mail communications routed via PO Box 1550.
So, if you’ve received a pension certificate or benefit update from this address, it’s highly probable that your previous plan has been integrated into Aviva’s system. Always cross-check with your personal pension records and look out for Aviva’s official contact details on the correspondence.
Is It Safe to Respond to Letters from This Address?

It is generally safe to respond to letters received from PO Box 1550 Salisbury SP1 2TW, provided they are genuinely from Aviva or related verified organisations. Aviva is a well-established and regulated financial services provider in the UK. Their use of PO Boxes is a standard practice for handling high volumes of sensitive client correspondence.
The key to safety lies in verifying the authenticity of the letter. Official communications will include clear branding, accurate contact information, and relevant personal details that match your pension or insurance records.
However, if you ever receive suspicious content or requests for highly sensitive data like passwords or bank PINs, do not respond directly. Instead, call Aviva through their official helpline to confirm the legitimacy before taking further action.
What Should You Do If You’re Unsure About the Sender?
If you are unsure about the sender of a letter from PO Box 1550, it’s best to take a cautious and structured approach.

You can also compare the letter’s content with previous communications from your pension provider. If something feels off or too urgent, take a pause and speak to a trusted financial advisor. Contacting the organisation through their official website is always the safest option when confirming authenticity.

What Is NCS Services and How Are They Involved?
NCS Services was responsible for managing the NCS Services Retirement Benefits Plan, a defined benefit pension scheme previously sponsored by Pearson Services Limited. In July 2020, the Trustee agreed to wind up the plan via a policy buy-out process. All plan assets were transferred to Aviva, and by November 2020, individual policies were issued to each member.
NCS Services played a crucial role in managing pension assets until the plan’s wind-up on 25 May 2021. After that point, all policy responsibilities and future communications moved to Aviva. This includes benefit enquiries, address updates, and claims processing—all of which now go through PO Box 1550.
While NCS Services no longer actively manages the pension, its historical connection explains why some members still receive communication via this PO Box.
