How to apply

You apply to your local council, and to nobody else. There is no national Council Tax Reduction claim form, no Department for Work and Pensions claim line, and no way to claim through a Universal Credit journal. Most councils offer an online claim form; if you cannot apply online, the council must offer another route, such as a paper form or a telephone claim. Use the GOV.UK council finder to reach your council's own page if you are unsure which council bills you.

Before you start

Have the following ready, for you and your partner: your council tax account number from your bill; National Insurance numbers; proof of identity and address; recent payslips or, if you are self-employed, accounts or tax records; award letters for benefits and pensions; and bank statements, usually for the last two months, for all accounts. If another adult lives with you, have their income details ready too, because non-dependant deductions and second adult rebate both depend on them. If you rent, the council may ask for your tenancy agreement, although the reduction itself does not depend on your rent.

What happens after you claim

The council assesses the claim and, if you qualify, credits your council tax account and sends a revised bill showing the lower amount and a new payment schedule. Processing time varies by council and by how complete the evidence is; some councils aim to decide within a couple of weeks of receiving the last document, but busy periods can take longer. Keep paying the amount on your current bill until the revised bill arrives: if you stop paying while waiting, you can build up arrears even though a reduction is on its way, and any reduction, once awarded, is applied from the claim date, so the overpaid amount is dealt with through the revised bill.

Backdating

A claim normally starts from the date the council receives it, or from the Monday following it under scheme rules — it does not automatically reach back to when you first became eligible. Pension-age claims can be backdated for up to three months where the backdating conditions are met. Working-age backdating depends on your council's scheme: many councils allow backdating where you can show good cause for the delay, such as illness or not knowing you could claim, and some allow a fixed period. If you delayed claiming, say so on the form and give the reason: a backdating request that is never made cannot be granted.

If you move house

A reduction does not move with you. Tell your old council you have left, and claim with the new council for the new address as soon as you can, because the new claim starts from its own date. If you move within the same council area, tell the council promptly so the reduction is transferred to the new property's account rather than left on the old one.

Claiming alongside other help

Claiming Council Tax Reduction does not claim any other benefit for you, and claiming another benefit does not claim Council Tax Reduction for you. If you are over State Pension age and not receiving Pension Credit, consider a Pension Credit claim at the same time: guarantee credit would give you the maximum reduction and may increase your overall income. If you need help with rent, that is a separate Housing Benefit or Universal Credit matter. Benefits calculators, including the one on GOV.UK, can give an estimate before you claim, but only your council's decision is definitive.
