How Often Can a Landlord Increase Rent in Scotland?

Once every 12 months — that is the hard statutory limit. Under Section 20 of the Private Housing (Tenancies) (Scotland) Act 2016, a landlord may only increase the rent on a Private Residential Tenancy once in any 12-month period, regardless of where the property sits in Scotland.

When the 12-Month Clock Starts

The clock starts on one of two dates:

For the first increase: the exact calendar date the tenancy began. If the PRT started on 3 June 2025, the earliest the first rent increase can take effect is 3 June 2026.

For subsequent increases: the date the most recent increase came into effect — not the date you served the notice, and not the date the tenant started paying the new amount. The effective date stated in the Rent-Increase Notice is the anchor.

What Does Not Reset the Clock

A few things landlords assume restart the 12-month period but do not:

• A withdrawn notice: if you serve a notice and later withdraw it because of an error, no rent change took effect. The clock keeps running from the tenancy start date or the last valid increase.
• A change of ownership: if the property is sold, the new landlord inherits the existing clock. The tenancy start date and last effective increase date carry over.
• A change of letting agent: swapping agents has no effect on the statutory timeline.

The Two-Clock Problem

The 12-month frequency rule is one of two clocks that must be satisfied before a rent increase can take effect. The other is the three-month notice period (plus 48 hours for postal or email delivery).

Both must clear simultaneously. If you serve your notice early — say nine months into the tenancy — the effective date still cannot fall before the 12-month anniversary. If you wait until after the anniversary to serve the notice, the three-month period starts on deemed receipt (48 hours after postal or email dispatch), and the rent can take effect no earlier than the day after that period expires.

To make the 12-month anniversary the effective date, dispatch a postal or email notice at least three days before the date three calendar months before that anniversary; hand-deliver it at least one day before that date.

Can You Skip a Year and Still Raise Rent?

Yes. Missing the 12-month anniversary does not forfeit your right to increase rent. You can go two, three, or five years without raising rent and then serve a notice at any time. The 12-month rule limits how soon you can increase again after the previous change, not how quickly you must act.

Some landlords froze rents during the emergency cost-of-living legislation (2022–2024). Those caps expired on 31 March 2024, and the statutory route is now fully available again. There is no penalty or restriction from having left rent unchanged for an extended period.

Practical Planning

Map both statutory clocks against your tenancy dates before you start filling in the prescribed form.
