Recover Lost Revenue with Intelligent Data Matching
With stretched budgets and increasing demand for services, ensuring council tax discounts are applied correctly has never been more important. However, identifying incorrect Single Person Discount claims is often a manual and time-consuming process, with valuable evidence spread across multiple systems.
At Sentinel, we help councils identify potential council tax fraud, incorrect discounts and upcoming changes in household circumstances, so councils can recover lost revenue, ensure discounts are applied correctly and proactively manage future changes.
The Challenge
Councils face ongoing challenges in maintaining accurate council tax records, including:
Single Person Discounts that may no longer be valid
Household composition changes that have not been reported
Residents approaching key eligibility milestones
Data held across multiple disconnected systems
Limited resources to manually investigate large numbers of accounts
Without a consolidated view, identifying these opportunities can be difficult, costly and time-consuming.
How it Works
Our platform brings together council tax records, electoral register data and other relevant council datasets into a single, trusted environment.
Using advanced matching, cleansing and entity resolution techniques, we create a "golden record" for each resident, providing a consolidated view of individuals, households and relationships across systems.
The platform then identifies potential rcases for review by highlighting indicators such as:
Households claiming a Single Person Discount where additional occupants may be present

Young people approaching their 18th birthday who may affect household eligibility

Residents linked to multiple properties

Electoral register information that differs from council tax records

Household composition changes identified through other council datasets

Cases with multiple indicators suggesting a review may be required

Rather than manually reviewing thousands of records, officers can focus on the cases most likely to require investigation.
