Adding a Flatmate to Your Tenancy in England: What Renters Must Know

Sharing a home can help split costs and chores, making renting more manageable. If you're a tenant in England, you might consider adding a flatmate or letting a friend move in. But before making room for someone new, it's essential to understand your rights and responsibilities under English housing law. This guide explains what you need to know about adding a flatmate to your tenancy, the necessary permissions, and the official steps to take.

Understanding Tenancy Types and Adding a Flatmate

Whether you can add a flatmate depends on your current tenancy agreement:

• Assured Shorthold Tenancy (AST): The most common rental contract in England.
• Joint Tenancy: All named tenants share equal responsibility.
• Sole Tenancy: Only one person (you) is listed as the official tenant.

Most tenancy agreements in England require the landlord's written consent before anyone else moves in, especially if that person will contribute to rent or bills.

Do You Need the Landlord's Permission?

In nearly all cases, yes. Your tenancy agreement usually includes a clause about subletting or having additional occupants. Adding a flatmate without permission could breach your contract, potentially risking eviction.^[1] Check your tenancy agreement for any restrictions or procedures around adding someone new.

Permission: What to Ask and How

• Contact your landlord or letting agent in writing, asking for formal consent to add your flatmate.
• Include your flatmate's full name and a brief explanation (for example, "wishes to move in as a joint tenant" or "to help with rent").
• If the landlord agrees, ensure you receive their confirmation in writing.

Your landlord may choose to:

• Add your flatmate’s name to a new tenancy agreement (creating a joint tenancy)
• Refuse the request – if your agreement prohibits additional tenants
• Allow a "permitted occupier" who can stay but does not have tenancy rights

What Makes Someone a Tenant, Lodger, or Subtenant?

It’s important to clarify:

• Tenant: Named on the tenancy agreement, with legal responsibility for rent and the property.
• Lodger: Lives with the tenant; has fewer rights and usually not named on the tenancy.
• Subtenant: Rents part or all of the property from a tenant, not directly from the landlord.

Adding a flatmate may result in you sharing responsibility for the rent and property, especially if they become a joint tenant. To ensure you both have protected rights, the landlord should update the tenancy agreement.

Legal Steps and Official Forms

If your landlord agrees to add a flatmate, they may:

• Ask you both to sign a new tenancy agreement listing both parties (creating a joint tenancy). This replaces your old contract.
• Require a reference or background check for your flatmate.

There is no standard government form specifically for adding a flatmate. The process usually involves a new written agreement. If your landlord issues a new tenancy, it should be clearly titled as a joint tenancy with both names.

If your flatmate moves in without the landlord’s consent and causes problems, the landlord can take legal action or issue a Section 8 notice (Form 3) for breaches such as subletting.^[2]

If Disagreements Arise

If you and your landlord disagree about adding a flatmate, you can seek advice or guidance from your local council or contact the First-tier Tribunal (Property Chamber – Residential Property).^[3]

Avoiding Unintentional HMOs

If three or more unrelated people live together, the property may become a House in Multiple Occupation (HMO). HMOs have extra safety and licensing requirements. Check with your local council if your household might become an HMO, as landlords must comply with more regulations.^[4] Not all properties are suitable for this.

Key Legislation Covering Tenancies in England

The rules and your rights are primarily set out in the Housing Act 1988 and updated with later laws such as the Housing Act 2004 (covering HMOs).

What to Do if You Need to Formalise Your New Flatmate

• Read your tenancy agreement for relevant clauses about subletting or additional occupiers.
• Ask your landlord for written permission before anyone moves in.
• If permission is granted, sign a new joint tenancy if possible.
• Keep copies of all correspondence and agreements.

Frequently Asked Questions

1. Can my landlord refuse to let me add a flatmate?
   Yes, your landlord can refuse if your agreement forbids it or if they don’t want additional tenants. Always check your contract and ask the landlord first.
2. Will adding a flatmate make my home an HMO?
   If three or more unrelated tenants live together, the property may become a House in Multiple Occupation (HMO), requiring your landlord to meet extra standards and possibly obtain a licence.
3. What should I do if my landlord won't add my flatmate to the tenancy?
   You can stay as sole tenant, but your flatmate will have no legal rights. If there’s a dispute, seek help from your local council or First-tier Tribunal (Property Chamber – Residential Property).
4. Do I need to sign a new tenancy agreement?
   If your flatmate is officially added as a joint tenant, you should both sign a new agreement showing you share responsibilities.
5. Can I just let a friend move in as a lodger?
   If you're the tenant and have the landlord's permission, you may be able to take in a lodger. Check your tenancy and always get written agreement from your landlord.

Key Takeaways for Renters

• Always read your tenancy agreement before making changes.
• Get clear, written permission from your landlord to add a flatmate.
• Understand that adding people may change your legal responsibilities and could turn your home into an HMO, triggering more rules.

Taking these steps can prevent misunderstandings and help you enjoy a smoother shared living experience.
