Who Pays for Previous Tenants’ Utility Bills in Wales?

If you’ve just moved into a new rented property in Wales and receive a bill for electricity, gas, water, or council tax from before your tenancy started, you may feel concerned or confused. Many renters want to know whether they are liable for the debts or utility usage of previous tenants, and what steps to take if they face demands for unpaid bills.

Can Renters in Wales Be Billed for Past Tenants’ Utilities?

Generally, you are not responsible for any utility charges or council tax incurred before your own tenancy began. In Wales, as in the rest of the UK, utility contracts (such as gas, electricity, water, and internet) are usually between the supplier and the person named on the account. If you are not named on the account during the period in question, you cannot be held liable for another tenant’s debt.¹

• Suppliers should only bill you from the date your tenancy agreement starts, or when you actually move into the property (whichever is later).
• Council Tax is generally charged from the day you become the liable resident. If a previous occupier left unpaid council tax, you are not responsible for that period.²

What To Do If You Get a Bill for a Previous Tenant

If you receive a bill for a time before your tenancy began, promptly:

• Take a copy of your tenancy agreement to show your official move-in date.
• Contact the utility provider and/or local council to explain, providing evidence of when your tenancy started.
• Request that your name is added to the account from your move-in date, and confirm that previous charges are not your responsibility.

If a provider continues to pursue you for payment, ask for their formal complaints process. Do not pay bills relating to periods before you were in the property unless you are certain you are liable.

When Can You Be Liable for a Previous Tenant’s Bills?

There are rare cases you might become liable, such as:

• If your name was mistakenly added to an account by the landlord or agent before you moved in.
• If your tenancy agreement includes clauses about existing debts (this is uncommon and may be challengeable).

Always check any such clauses and get advice if they seem unfair or unusual.

What the Law Says: Key Legislation in Wales

Your tenancy and liabilities are governed by the Renting Homes (Wales) Act 2016, as well as the rules of individual utility suppliers. Council tax is set by your local authority and covered by the Local Government Finance Act 1992.³

• Landlords must not pass on outstanding utility or council tax bills that accrued before your tenancy.
• Utility companies can only pursue individuals whose names are on the contract for the arrears period.
• If you face a dispute, the Residential Property Tribunal Wales is the official tribunal for Welsh renters.⁴

Helpful Official Forms and Actions

• Council Tax Dispute:
  • Council Tax Appeal Form (VT01 England & Wales) – Use this to appeal council tax liability if wrongly billed.
  • How to use: Complete if the council will not correct your liability after you’ve provided proof. Attach your tenancy agreement, and submit to the relevant Valuation Tribunal.
• Utility Billing Errors:
  • Most suppliers have their own complaint forms online. Start with a formal written complaint before using the Energy Ombudsman.
  • Example: If your name is incorrectly linked to a previous bill, cite your tenancy start date and request removal of charges.
