Brent Council Tax Reduction: Reporting a Change of Circumstances

The 21-day reporting rule

If you're receiving Council Tax Reduction in Brent, you're legally required to report any material change in your household circumstances within 21 days of the change happening. This isn't optional guidance — it's a condition of your award, and failure to report can result in overpayment recovery.

What counts as a reportable change

Anything that could affect your income band, capital position, or household composition:

• Income changes: your earnings go up or down by enough to shift your weekly income band (even £10 can tip you from Band 1 to Band 2)
• Universal Credit changes: your UC award changes — new elements added, sanctions applied, or earnings recalculated
• Savings hitting £6,000: your combined bank balances and investments reach the capital cutoff
• Non-dependant moves: an adult (not your partner or child) moves in or out, or changes from employed to unemployed or vice versa
• Partner changes: you start or end a relationship with someone living at your address
• Moving house: you leave the property or move to a different address in Brent
• Extended absence: you are away for more than 13 weeks within Great Britain (up to 26 weeks in specified medical or care circumstances), or for more than 4 weeks outside Great Britain

How to report

Report through your My Account on brent.gov.uk. Log in, navigate to the Council Tax Support section, and submit a change notification. Keep a record of the date you reported and any reference number you receive.

You can also report by phoning Brent Revenues and Benefits, but always follow up in writing through the portal. A phone call alone may not create a verifiable audit trail, and if there's ever a dispute about when you reported, you'll want that digital timestamp.

Don't rely on the DWP to pass it on

If your Universal Credit changes, the DWP does share data with Brent Council — but this does not satisfy your legal obligation to report directly. If the DWP notification gets delayed or doesn't route through correctly, and your CTR isn't adjusted in time, you're responsible for any overpayment that accumulates.

Report to both bodies. It takes five minutes through the portal.

What happens when you don't report

When Brent discovers an unreported change — often through DWP data matching or a routine review — they recalculate your CTR retrospectively. Any amount you were overpaid becomes "Excess Council Tax Reduction."

Unlike Housing Benefit overpayments, excess CTR isn't recovered through a separate invoice. Instead, Brent adds the overpaid amount back onto your council tax account. You'll receive a revised bill with higher remaining instalments. If the overpayment is large and discovered late in the tax year, those revised instalments can be steep.

Changes that work in your favour

Not all changes increase your bill. If your income drops, a non-dependant moves out, or you become eligible for the Single Person Discount, reporting quickly means your CTR is adjusted upward and your bill goes down sooner.

If your income drops, a non-dependant moves out, or you become eligible for a discount, report the change within 21 days so Brent can reassess your award.

The Brent Council Tax Reduction guide includes a change-reporting log to track what you reported, when, and the council's confirmation — essential protection if there's ever a dispute about overpayment.
