Free Help With Council Tax in Hillingdon: Phone Numbers, Advice Services, and Where to Start
Hillingdon Council's Own Helplines
For anything directly about your council tax bill, payments, or applying for Council Tax Reduction, Hillingdon Council's revenues and benefits team is the starting point.
General council tax enquiries and CTR applications: 0300 123 1384. This line covers billing questions, payment arrangements, discount applications, and requests for paper CTR application forms if you can't use the online portal. Lines are typically busiest on Mondays and the first week after annual bills go out in March.
Online applications: Hillingdon uses an NEC-powered self-service portal for CTR claims. You can access it through the council's website and save your progress for up to 14 days using a transaction key. The portal closes nightly between 23:15 and 00:15 for maintenance.
Email for evidence submission: [email protected]. If you've already started an application and need to submit supporting documents — payslips, bank statements, UC award breakdowns — you can email them to this address quoting your council tax reference number.
Citizens Advice Hillingdon
Phone: 0808 278 7893
Citizens Advice Hillingdon provides free, independent, confidential advice on council tax queries including whether you qualify for a reduction, how to challenge a decision, and what to do about arrears. They can help you understand Hillingdon's income banding grid and check whether you're in the right band.
They also handle council tax debt cases — if you've received a liability order or bailiff notice, Citizens Advice can negotiate with the council on your behalf and check whether enforcement fees have been correctly applied.
Appointments fill up quickly. If you can't get through on the phone, the national Citizens Advice website has detailed council tax guides that cover most common questions while you wait for a local appointment.
Hillingdon Advice Partnership
The Hillingdon Advice Partnership (HAP) is a single point of access for Hillingdon residents aged 18 and over who need advice on welfare, benefits, housing, or wellbeing.
HAP prioritises complex and vulnerable cases — residents dealing with multiple debts, health conditions, or housing crises alongside council tax problems. If your situation is straightforward (you just need to apply for CTR), the council's own portal is faster. But if you're dealing with overlapping issues — council tax arrears combined with rent arrears and benefit sanctions, for example — HAP can look at the full picture.
Hillingdon Advice Partnership: 020 8044 5676. Contact HAP about welfare, benefits, housing, or wellbeing advice.
Age UK Hillingdon, Harrow and Brent: 020 8756 3040. Primarily serves residents over 50.

When to Use the Guide Instead
These services are free and cover everything from initial applications to complex appeals. The waiting times and availability are the constraint — Citizens Advice and HAP both operate at capacity, and routine CTR queries can take weeks to get an appointment for.
The Hillingdon Council Tax Reduction guide is designed for residents who want to prepare their own application without waiting. It covers the income bands, evidence requirements, the UC element deduction rules, and the backdating process in a single printable workflow. If you hit something you can't resolve with the guide, the services listed above are the next step — and having your documents already organised makes their job faster too.
