Council Tax when two tenancies overlap during a move

Katerina Galkina · EN · 07/10/2026

Rent dates alone do not establish liability

Where the new tenancy has started but the old one continues, council tax is assessed separately from rent. Main residence, legal liability for each property, agreement terms, dates and vacancy status matter. “I no longer sleep there” does not always end charges; receiving two bills does not establish that both calculations are correct either.

This concerns England, including London. Check local rules in Scotland and Wales; Northern Ireland has domestic rates. See the general Council Tax rules ↗.

Collect dates and evidence

Record the new agreement's start, actual move, old agreement's end and key return separately. Note who remained at the previous address and when it became empty. Keep agreements, notice, any early-ending agreement and checkout confirmation.

For a room let, establish the liable person: the owner pays council tax for some HMOs, and this is separate from HMO licensing. Westminster Council provides a local explanation ↗. Do not automatically accept an additional separate payment to the owner without checking the agreement and lawful arrangements.

Tell both councils

Find the authorities for both addresses through GOV.UK ↗. Submit moving-out and moving-in details, including where both addresses are in one borough. Give the actual departure date and end of contractual responsibility, and ask which date the council used to end charges and why.

Procedures differ: Westminster, for example, has an official registration and moving form ↗. Retain the submission reference. Request a final old-address bill, the new assessment, credit for payments already made and a refund of any overpayment.

Discounts and disputed periods

An empty property is not automatically exempt. Empty-property discounts depend on local policy, while second homes and long-term empty homes may attract additional charges. Do not decide yourself that an ordinary brief moving overlap is exempt or a second home. See GOV.UK on empty and second homes ↗.

Single person discount does not transfer automatically either: report the new household and apply as required. If a calculation is unclear, send a written request with a date table and evidence. If you disagree, request a liability decision and appeal procedure rather than simply cancelling the Direct Debit. Challenging a bill does not normally permit you to stop paying without agreed arrangements. Seek help from the council or an adviser if overlapping charges are unaffordable or enforcement deadlines are approaching.
