First Rent Increase Scotland PRT: When and How to Raise Rent on a New Tenancy

The first rent increase on a Scottish PRT sits in an awkward planning gap. You set the initial rent when the tenancy started, and now costs have risen or you have realised the property is underlet. The statutory procedure is the same as any subsequent increase, but the timing has a few traps specific to the first time around.

When the 12-Month Clock Starts

For the first increase on a PRT, the 12-month frequency clock starts on the exact calendar date the tenancy began — not the date the first month's rent was paid, not the move-in date, and not the date the tenancy agreement was signed if those differ.

If the tenancy started on 8 April 2025, the earliest the first rent increase can take effect is 8 April 2026. You cannot serve a notice with an effective date before that anniversary, even if you serve the notice months in advance.

Serving the Notice Early

You do not have to wait until the 12-month mark to serve the notice. You can serve it any time during the tenancy — but the effective date on the form must fall on or after the anniversary, and the three-month notice period must expire before that date. For post or email, deemed receipt is 48 hours after dispatch.

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.

What If You Underlet From Day One?

Landlords who set a below-market rent to attract a tenant quickly — or who inherited a tenant at a historic rate — sometimes want to make a larger jump with the first increase. There is no statutory percentage limit on the proposed amount outside a designated Rent Control Area (none exist in Scotland as of October 2026).

But the tenant can refer the notice to Rent Service Scotland within 21 days (30 days from April 2027). If they do, the Rent Officer applies the transitional taper formula, which limits the maximum approved increase to 12% regardless of how far below market the current rent sits. Getting from a deeply underlet position to market rate takes multiple annual increases.

Mid-Tenancy Adjustments vs First Increase

There is no legal distinction between a "first" increase and any later one. The procedure is identical: prescribed form (Schedule 2 under SSI 2017/297), all three parts served together, correct service method, three months plus 48 hours, effective date on or after the 12-month anniversary.

The only practical difference is that first-time landlords often lack a service history. Keep your original tenancy agreement, the first month's bank transaction record, and whatever evidence you have of the tenancy start date. If the increase is ever challenged, you will need to prove the 12-month clock's start point.

What Not to Do

Do not try to increase rent through an informal letter, an email asking the tenant to agree to a higher amount, or a conversation at the property. Under the 2016 Act, none of these create any obligation to pay more. The tenant can simply ignore the request, and the existing rent stands until a statutory notice is properly served and expires.

Do not assume a rent review clause in the tenancy agreement gives you an alternative route. The 2016 Act's statutory procedure overrides all contractual provisions for PRTs.

Get the Timeline Right the First Time

A miscalculated first notice means waiting at least another three months before you can try again. Our Scotland rent increases guide includes a dual-clock calculator that maps the 12-month anniversary against the three-month notice period, so you can pinpoint the earliest effective date and the ideal service date for your specific tenancy.
