Tenant Challenge Rent Increase Scotland: What Happens When They Dispute

You have served a statutory Rent-Increase Notice, the dates are correct, and you used the prescribed form. Then the tenant pushes back. This is not unusual — and it is not a crisis, provided you understand the process that follows.

The Tenant's Two Options

A tenant who disagrees with a proposed rent increase has two formal routes:

Return Part 3 of the notice. Part 3 is the response form attached to the statutory Rent-Increase Notice. If the effective date is before the day after the full three-month notice period expires (calculated from deemed receipt, 48 hours after postal or email dispatch), the tenant can return Part 3 to confirm they will not pay the new rent until the lawful date arrives. This does not cancel the increase — it just delays it.

Refer the notice to Rent Service Scotland. Within 21 calendar days of receiving the notice (extending to 30 days from April 2027), the tenant can submit a formal referral to Rent Service Scotland using the prescribed Schedule 3 form. This triggers an independent rent adjudication.

A tenant who simply refuses to pay the higher rent without taking either formal step is still liable for the increased amount once the notice period expires — assuming the notice is valid. Informal refusal does not override a properly served statutory notice.

What Happens During a Referral

Once Rent Service Scotland receives the referral, the clock pauses. The tenant continues paying rent at the existing rate while the adjudication is pending. The proposed increase is suspended.

RSS notifies the landlord and requests written representations, tenancy documentation, and details of any recent improvements to the property. A Rent Officer may schedule a physical inspection to assess the property's condition, size, and amenities.

RSS aims to issue a determination within 40 days. The Rent Officer determines the adjudicated rent using open-market evidence and the transitional taper formula.

The Outcome You Need to Prepare For

If the Rent Officer approves an increase, the adjudicated rent takes effect from the original date stated in your notice unless the Rent Officer specifies a deferred date due to undue hardship. The tenant becomes liable for any applicable shortfall accumulated during the adjudication period.

If the Rent Officer determines the open-market rent is lower than what you proposed, the adjudicated figure becomes the new rent. In rare cases under the current rules (pre-April 2027), this can result in a rent set lower than the existing contractual rate — an actual reduction.

From April 2027, new statutory rules prevent any adjudicator from setting rent higher than the landlord's proposed figure. But the risk of a downward determination remains.

How to Strengthen Your Position

Landlords who prepare evidence before serving the notice are in a far stronger position if a referral follows:

• Gather three to five rental listings for comparable properties in the same area — similar size, condition, and amenities
• Document any improvements made since the last rent was set
• Keep a clean payment history and copies of all previous notices

If the increase aligns with verifiable market data, the Rent Officer has little room to reduce it.

After the Determination

If either party disagrees with the outcome, the next step is an internal review by RSS (within 14 working days), followed by an appeal to the First-tier Tribunal using Form H (within 14 working days of the review decision). Both routes are free.
