Scottish PRT Rent Increase 2026 — Complete Landlord Guide to Rent Increase Notice and Rent Service Scotland

Serving the Rent Increase Notice — requirements and timing

The Rent Increase Notice must comply with the Private Housing (Tenancies) (Scotland) Act 2016 and the Private Residential Tenancies (Statutory Terms) (Scotland) Regulations 2017:

• Prescribed form: The Rent Increase Notice must be in the prescribed form (set out in Schedule 3 to the Private Residential Tenancies (Statutory Terms) (Scotland) Regulations 2017). The notice must state: (a) the proposed new rent; (b) the date from which the new rent will take effect; (c) the tenant's right to refer the proposed increase to Rent Service Scotland within 21 working days of receiving the notice; and (d) the Rent Service Scotland contact details. An informal letter or email stating a rent increase is not a valid Rent Increase Notice unless it satisfies all the prescribed form requirements
• Minimum 3 months' notice (84 days): The Rent Increase Notice must give the tenant at least 3 calendar months' notice before the new rent takes effect. This is measured from the date the notice is served (the deemed service date, allowing for postal delays). A notice giving only 2 months' notice is invalid — the new rent cannot take effect until at least 3 months after valid service. For a rent increase effective from 1 October 2026, the notice must be served no later than 1 July 2026 (or earlier, allowing for postal service). If in doubt, serve the notice earlier
• One increase per 52-week period: A landlord can only increase the rent under a PRT once in any 52-week period (not once per calendar year). If the landlord increased the rent on 1 March 2025, the next earliest effective date for a further increase is 1 March 2026 (52 weeks later). A Rent Increase Notice served that would result in a second increase within 52 weeks is invalid. Landlords should keep a clear record of each rent increase date to ensure compliance with this restriction
• Service methods — deemed service dates: The Rent Increase Notice can be served by: (a) personal delivery (deemed served immediately); (b) first-class post (deemed served 2 business days after posting); (c) second-class post or recorded delivery (deemed served 2 business days after posting); (d) email or other electronic method if the PRT agreement includes a valid electronic service clause permitting electronic service of notices. Always retain evidence of service: a certificate of posting; a tracked delivery receipt; or a signed acknowledgement from the tenant

The tenant's right to refer to Rent Service Scotland

The tenant can challenge the proposed increase by referring to Rent Service Scotland (RSS) within 21 working days of receiving the Rent Increase Notice:

• 21 working days — not calendar days: The tenant's referral window is 21 WORKING DAYS from the date they received the Rent Increase Notice (the deemed service date). Working days exclude weekends and Scottish public holidays. A tenant who receives the notice on Monday 1 June 2026 has until approximately Monday 30 June 2026 (21 working days) to refer to Rent Service Scotland. Landlords should note that the 21-working-day window is more generous than it first appears — it gives tenants approximately 4-5 calendar weeks to decide whether to refer
• What Rent Service Scotland assesses: Rent Service Scotland (RSS) is the Scottish Government body responsible for determining rent disputes under PRT legislation. If the tenant refers, an RSS rent officer assesses the open market rent for the property (taking into account comparable properties in the area, local rental market conditions, the property's condition and facilities, and any other relevant factors). The RSS determination sets the rent at the assessed open market level — which may be: (a) equal to the proposed new rent (landlord's increase confirmed); (b) higher than the proposed new rent (extremely rare — the proposed rent was too low); or (c) lower than the proposed new rent (the landlord's increase is reduced to the market rate)
• Effect of RSS determination — the rent cap: If RSS determines that the open market rent is LOWER than the landlord's proposed new rent, the lower (RSS-determined) rent applies from the effective date stated in the Rent Increase Notice. The RSS determination effectively caps the rent at the open market level — a landlord cannot obtain more than open market rent via the PRT review process. If RSS determines the open market rent is EQUAL to or HIGHER than the proposed new rent, the landlord's proposed new rent applies in full
• If the tenant does NOT refer to RSS: If 21 working days pass without the tenant referring to Rent Service Scotland, the proposed new rent takes effect on the date stated in the Rent Increase Notice (provided the notice is valid and at least 3 months' notice was given). No further action is required by the landlord — the new rent simply becomes due. The landlord should keep a record of the notice service date and note that the 21-working-day referral window has passed without challenge

First-tier Tribunal appeal — landlord and tenant rights

Either party can appeal the Rent Service Scotland determination to the First-tier Tribunal (Housing and Property Chamber):

• Who can appeal: Both the landlord and the tenant can appeal a Rent Service Scotland rent determination to the First-tier Tribunal (Housing and Property Chamber). A landlord who believes the RSS determination is too low (i.e., the assessed open market rent does not reflect comparables), or a tenant who believes it is too high, can appeal to the Tribunal. The appeal must be lodged within the timeframe specified in the RSS determination notice
• First-tier Tribunal (Housing and Property Chamber) — rent determination: The Tribunal is the specialist housing court for Scotland. For rent disputes, the Tribunal considers the same factors as Rent Service Scotland but may reach a different conclusion on the evidence. The Tribunal can: (a) confirm the RSS determination; (b) increase the rent (if the landlord's appeal shows open market rent is higher than RSS determined); (c) decrease the rent (if the tenant's appeal shows open market rent is lower than RSS determined). The Tribunal determination is binding. Further appeal (on a point of law only) lies to the Upper Tribunal for Scotland
• Rent during the referral and appeal period: While the referral to Rent Service Scotland (or appeal to the First-tier Tribunal) is pending, the current rent (i.e., the rent before the proposed increase) continues to be payable. The new rent (whether the landlord's proposed rate or the RSS/Tribunal-determined rate) takes effect only once the determination is made and the notice period has expired. This can create a period of uncertainty for landlords — particularly for large rent increases where a significant rental income uplift is anticipated
• Historical context — Scottish rent freeze ended 31 March 2024: The Cost of Living (Tenant Protection) (Scotland) Act 2022 imposed an emergency rent freeze from September 2022, followed by a rent cap of 3% per year for private landlords (with limited exceptions for mortgage cost increases up to 6%). The freeze/cap ended on 31 March 2024. From 1 April 2024, the full PRT rent review process applies without restriction. Landlords wishing to increase rents to current market levels following the freeze/cap period should note that if the open market rent has risen significantly, an RSS referral from the tenant may still cap the increase at the assessed open market level — which should itself reflect the post-freeze market

Common mistakes and how to avoid them

The most frequent PRT rent increase errors that result in the increase being invalid:

• Failing to use the prescribed form: A text message, informal letter, or verbal notification of a rent increase is not a valid Rent Increase Notice. Always use the prescribed form (Schedule 3 to the Private Residential Tenancies (Statutory Terms) (Scotland) Regulations 2017), which includes the mandatory tenant's referral rights wording. The Scottish Government publishes the current form via the private rented sector section of the Scottish Government website
• Giving less than 3 months' notice: The most common mechanical error. Count from the deemed service date, not from the date of writing the notice. For a rent increase effective 1 January 2027, the notice must be served by 1 October 2026 at the latest (allowing for postal deemed service). For safety, serve at least a week earlier to account for posting delays
• Attempting a second increase within 52 weeks: A second Rent Increase Notice served within 52 weeks of the previous increase taking effect is invalid. Keep a clear rent increase log showing the date each increase took effect — not just the date the notice was served. The 52-week period runs from the date the PREVIOUS increase took effect, not from when the notice was served
• Failure to retain evidence of service: If the tenant later disputes that the Rent Increase Notice was received (and therefore claims the 21-working-day referral window has not expired), the landlord must be able to prove service. Certificate of posting, tracked delivery confirmation, or a signed acknowledgement from the tenant provides this evidence. Email delivery receipts (where electronic service is agreed) also work — but ensure the tenant's email address is correct and matches the tenancy agreement
