Sharing Bills in Wales: What Renters Need to Know

If you rent a room or share a house or flat in Wales, it’s common to split utility bills—like electricity, gas, broadband, and council tax—with your housemates. But are you legally required to divide bills equally, and what protection do you have if someone doesn’t pay their share? Understanding the rules around sharing bills in Wales is important for a smooth co-living experience and to protect your rights as a renter.

Do You Have to Share Bills Equally in Shared Houses and HMOs?

There’s no law in Wales that says housemates must split utility bills equally. How you divide bills and who is responsible depends on:

• The type of tenancy agreement you have (joint or individual)
• Who is named on the bills or contracts
• Whether bills are included in the rent
• Any private agreements you make with your housemates

This means that it’s down to you and your housemates to agree on a fair way to share bills—unless your agreement with the landlord specifies otherwise.

Bills Included in the Rent

Some landlords offer ‘bills included’ rents, especially in Houses in Multiple Occupation (HMOs). In these arrangements, the landlord is responsible for paying the utility bills, and you pay a fixed amount for rent and bills. Always check your occupation contract and ask your landlord if you’re unsure. For more details about your rights and sample contracts, see the official Welsh Government Renting Homes resources.

If You and Your Housemates Pay Bills Directly

If bills are not included, the responsibility usually falls on whoever is named on the utility accounts. With a joint tenancy (a ‘joint contract’ in Wales), all named tenants can be held jointly responsible for any unpaid bills.^[1] With individual contracts, each tenant typically only pays for their own room, but bills may still be communal or shared.

It’s wise to agree in writing (an email is enough) how you’ll split bills, such as evenly or based on room size or usage. While this agreement isn’t legally binding in the same way as a contract with a utility company, it can help resolve disputes.

What Happens If Someone Doesn’t Pay Their Share?

If you’re the only one named on a bill, the utility company will pursue you for the full amount, even if others have promised to pay their share. With joint contracts or where all housemates are named, the company can usually chase any of you for the whole debt (‘joint and several liability’). This is why clear agreements and good communication between housemates are so important.

Resolving Disputes and Making Complaints

For renters in Wales, there is currently no official government form for dividing or disputing household bills between tenants. Disputes about utility bills are considered civil matters between individuals. If a housemate won’t pay, you may be able to claim their share in the small claims court.^[2]

If the issue stems from landlord negligence (for example, not passing on payments if bills are meant to be included in the rent), you can complain formally.

Relevant Official Forms and How to Use Them

• RHW5: Notice to End a Periodic Standard Contract – Use this form if you want to leave your tenancy because of ongoing disputes and are on a periodic standard contract. Always check your rights before ending your agreement. See RHW5 and other official forms here.
• Renting Homes (Wales) Act 2016 – This is the main tenancy law in Wales. It covers your occupation contract, your rights, and when bills can be included. Read the full Act here.

The Residential Property Tribunal Wales handles legal disputes about rents, deposits, and conditions but not private bill disputes between housemates.

How to Prevent Bill Disputes

• Hold a meeting when you move in to discuss how bills will be split
• Agree who will set up and pay each bill (utilities, internet, council tax, etc.)
• Keep a record of payments or use a shared app
• Put your agreement in writing—plain language is fine

Clear communication and documentation are your best tools for avoiding confusion or conflict.

FAQs About Sharing Bills in Wales

1. Do all housemates have to pay an equal share of the bills in Wales?
   

   No, it depends on what you all agree to and who is named on the bills. There’s no automatic legal requirement to split bills equally unless your contract states so.

2. Is my landlord responsible for the bills in a shared house?
   

   Your landlord is only responsible if your contract says bills are “included.” Otherwise, responsibility lies with whoever is named on the utility bills.

3. What can I do if my housemate refuses to pay their share?
   

   Try to resolve it informally first. If that fails, you could consider a small claim through the courts. Mediation services or speaking to your local council can help.

4. How can I leave a shared tenancy due to bill disputes?
   

   If you’re on a periodic standard contract and want to leave, use the RHW5 notice form to end your contract—following your agreement’s notice period and rules.

5. Where can I get official advice about bills and shared property agreements?
   

   The Welsh Government, Shelter Cymru, and your local council are good places to start for free advice about shared tenancies and bills.

Summary: What to Remember About Sharing Bills

• Responsibility for bills usually falls on those named on the bill
