Unless there is a clear error in the final settlement, the landlord can maintain their view of the settlement.
If you and your landlord are unable to reach an agreement on the final settlement, you have the option to refer the case to the Rent Dispute Tribunal (HTU).
HTU will carefully review the case and make a decision, which will either support your position or that of the landlord.
Once the case is submitted to HTU, you will be asked to upload the relevant documentation in the Keyhole app to confirm that the case has been created.
