Council tax and moving house: exactly what to tell the council — and what it costs to get wrong.
One in three moves goes wrong somewhere: you get billed for a home you've left, or the band is set wrong before the first bill lands. This is the checklist that stops it happening to you.
The checklist — everything to do before and after the move
-
Tell your old council you're leaving
From the day you move out (not the day your tenancy/contract ends if they differ), your liability at the old address ends. If the old council isn't told, they can keep billing you for a property you don't live in. Every council has an online form — find yours via the gov.uk "council tax" portal.
-
Register with the new council from your move-in date
You're liable from the day you become the resident. If they don't know who's living there, they may bill "the owner" or backdate a demand. Give them the exact move-in date, names of everyone over 18, and your tenancy or completion reference.
-
Check your new band — don't just accept it
For existing homes, the band was set in 1991 or 2003 and follows the property, not the buyer. For new-builds, the developer or council sets a provisional band — mistakes are common and expensive. Use the gov.uk band checker and cross-check the neighbours' bands on the same street.
-
Single-person discount — both directions
If you've become the only adult at the new address, apply for the 25% single-person discount from day one. Equally, if someone has joined your household at the old address, notify the council — correcting the record is the right move and prevents an unexpected backdated bill later.
-
Check the first bill for the wrong period
When the first bill arrives at the new address, check the start date. If you're being charged for days before you lived there, you can get it corrected. If the old council is still billing you after you've gone, chase it in writing and keep the reference.
-
If you were overcharged — claim it back
Council tax overpayments are recoverable. Ask the council for a refund of the overpaid amount (they will usually credit your account, but you can request a bank transfer). There's no time limit shorter than the 6-year limit on recovering the debt in England and Wales — so check past bills too.
What getting it wrong actually costs
Getting a band wrong by one step on a typical band D home is roughly £150–£250 a year, every year, until it's corrected. A missed single-person discount is 25% of the bill — around £350 a year on the same home. Wrong-period billing during a move can add up to a month of double payment. Most of this is fixable if you catch it — the checklist above is how.
