Rent, regulation & indexation 3 min read · published September 11, 2025

As a tenant in Denmark you may need to set or assess a fair sublet rent — for example when subletting the whole dwelling, a room or sharing rent. This guide explains practical steps to calculate sublet rent, which types of costs can be included, and how the Rent Act and the practices of the rent tribunal affect the amount. We cover documentation, written agreements and what to do if the landlord or subtenant disagrees. The aim is to give you clear tools so you can act confidently, avoid misunderstandings and get help from relevant complaint bodies in Denmark.

What is fair sublet rent?

Fair sublet rent means that the rent you charge for subletting is reasonable in relation to actual costs and the market level. The rules in the Rent Act[1] set the framework for what can be claimed, and unreasonable surcharges may be set aside by the rent tribunal or the courts.

In most cases the Rent Act affects the rules for subletting.

How do you calculate sublet rent?

The following steps help you create a realistic and documented calculation basis so both the subtenant and any complaint bodies can assess the amount.

  • Calculate your total monthly rent and fixed expenses that can be shared.
  • Include reasonable shares of heating, water and maintenance.
  • Keep accounts of receipts, invoices and the condition of the property.
  • Consider local market rent as a comparison basis.
Detailed documentation increases your chances of success in disputes.

Documentation and written agreements

A clear written sublet contract makes it easier to defend your claim. Specify amounts, payment periods, what is included and how deposits are handled. Keep receipts and photos of the property condition at handover.

  • Draft a sublet contract that states the rental period and amount.
  • Keep photos of the property condition at handover.
  • List all shared payments and deposits clearly in the agreement.
Get the agreement in writing and signed by both parties.

If a dispute arises

Always start by contacting the other party and try a written solution. If you cannot agree, the case can be brought before the rent tribunal[2], which assesses reasonableness. As a last resort, the case may be handled by the courts.

  • Contact the landlord first and propose a written resolution.
  • Submit documentation to the rent tribunal if you cannot agree.
  • As a final step the case can be brought to the district court.
Respond to inquiries from the rent tribunal within stated deadlines.

FAQ

Can I charge extra rent when subletting?
You may only charge an amount that reasonably reflects expenses and the market; unreasonable surcharges can be complained about to the rent tribunal.
Do I need the landlord's permission to sublet?
Often the contract or the Rent Act requires the landlord's approval; check your lease and contact Borger.dk for guidance.[3]
What about deposit when subletting?
A deposit for subletting must be clearly agreed in the contract; the tenant and subtenant should document repayment at move-out.

How to

  1. Calculate total monthly costs (rent, heating, water, common expenses).
  2. Allocate the amount by share, number of occupants or square meters.
  3. Prepare a written sublet contract with amounts and terms.
  4. Get signatures from both parties and keep copies of documentation.
  5. If disputed: bring the case to the rent tribunal or consider legal action.

Key takeaways

  • Fair sublet rent reflects actual costs and the local market.
  • Documentation like receipts and photos protects your position.
