SPD reviews require thousands of letters to be sent and returned. Using a PO Box ensures that all replies are sent to a central location, simplifying sorting, logging, and follow-up. It also enables consistent tracking of responses and reduces administrative backlog.
Data Protection
By using a PO Box rather than an open council office address, RBKC protects the personal information of residents during the SPD review process. The PO Box ensures that responses are not mixed with general council enquiries, preserving confidentiality.
Contracted Outsourcing
RBKC has contracted a third-party service provider to manage the SPD review process. The use of a dedicated PO Box ensures a direct route for communications to the team handling these reviews, allowing for faster and more reliable processing of returned declaration forms.

The PO Box helps facilitate their backend services, maintaining streamlined communications between residents and the council through a centralised, controlled entry point.
What Is the Council Tax Single Person Discount (SPD) Review?
The Single Person Discount (SPD) Review is an initiative undertaken by local councils to verify that individuals receiving a 25% discount on their council tax are eligible for it. T
his discount is intended for residents who live alone in a household. However, over time, household circumstances may change without notification, which can lead to incorrect claims.
To prevent errors and fraud, councils periodically review these accounts. The review process involves contacting residents who are currently receiving the SPD and asking them to confirm their living situation.
This helps local authorities ensure that tax benefits are allocated fairly and accurately. If a household no longer qualifies for the discount, it can be removed to reflect updated living conditions.
The SPD Review is not a penalty but rather a verification step aimed at upholding accountability in public taxation and ensuring that financial assistance reaches the right individuals.
What Should You Do If You Receive an SPD Review Letter?

If you’ve received an SPD review letter, it means the council needs you to confirm that you still qualify for the Single Person Discount on your council tax.
You are required to respond promptly using one of the official channels:
- Online Submission: Visit the secure review portal at the address listed in the letter and use your 10-digit reference code to complete the form.
- By Phone: Call the dedicated helpline number listed in the letter to complete your review.
- By Post: Fill in the provided declaration form and return it to PO Box 152, Twickenham TW2 6XZ.

What Happens If You Don’t Respond to the SPD Review Request?
Failing to respond to an SPD review request can have direct consequences for your council tax status.
Removal of Discount
If you don’t reply within the requested timeframe, your Single Person Discount will likely be removed. This results in your council tax reverting to the full amount, increasing your financial obligation.
Potential Investigations
Continued non-response may prompt further investigations. The council may initiate an audit or seek to verify your household status through alternative records.
Reinstatement Requires Evidence
Once removed, reinstating the SPD may require additional paperwork and proof of your eligibility. This process can be time-consuming and may delay future billing adjustments.
In short, responding promptly is crucial. The process is simple and designed to ensure fairness, not to penalise. If your situation has changed and you’re no longer eligible, it’s still important to declare this honestly.
