Moving out: council tax, utilities and the admin of one person leaving

REVIEWED BY: Sean McNamara on 2026-08-31

Why this admin matters legally

The dull paperwork of separation — who is liable for council tax, whose name is on the electricity account, who tells the council — creates real liabilities. Joint liability doesn't end because one of you moved out, and unpaid bills run up against the person who stayed and the person who left. Sorting it in week one is cheap; sorting it at the financial hearing is expensive.

Council tax

Who is liable? The person(s) named on the council tax demand. If the demand names both of you (or the property is jointly owned/tenanted), both are jointly and severally liable even after one moves out — until the liability changes.
Single person discount (25%) applies when only one adult remains resident. Tell the council in writing the date the other person moved out; keep proof (new tenancy, forwarding address). Don't claim it while they still sleep there most nights — false discount claims are prosecuted.
Leaving because of domestic abuse: you can be treated as no longer resident and you will not usually be chased for the ex-property's council tax once your new address and circumstances are evidenced; the local authority's policies on fleeing abuse vary, so put your position in writing and keep copies (see our housing-domestic-abuse guide).
Empty property: if nobody lives there (e.g. it's now a disputed second home), premiums for empty/furnished-unused properties can apply — nobody "escapes" the demand by moving out; check with the council who they hold liable and correct it in writing.
Students, carers, exemptions: specific classes (full-time students, people with severe mental impairment, live-in carers) can reduce or zero the bill; check your council's page.

Utilities, TV, broadband

Bills in one name only: that person is solely liable — simple. Bills in joint or the other's name: you may still use the supply, but agree in writing how usage is shared, or put accounts in your own name with a meter reading on the move-out date.
Take date-stamped meter photos and final readings on the day someone leaves — this ends most later arguments about who used what.
Never simply stop paying a joint utility mid-dispute: arrears hit both credit files.

The move-out letter

Send a short written notice (email is fine) to the ex and to each provider: date of departure, forwarding address (or that it is confidential — see our DA confidentiality concerns), that you take no further liability for the property's accounts after that date, and your meter readings. Keep it factual; no accusations. This letter is evidence in later proceedings and ends most "they left us with the bills" disputes.

Interaction with financial remedy

Occupancy and who pays what also matter substantively: whoever pays the mortgage/rent and bills after separation builds a contribution record, and the court will consider housing needs of both households (see our financial-remedy and maintenance-pending-suit guides). Keep a simple monthly log of who paid what — it converts directly into Form E figures.
