Scotland Rent Increase Three Months Notice: How the Notice Period Works

Scottish landlords cannot increase rent on a Private Residential Tenancy without giving three full calendar months of notice. Not 90 days, not "about three months" — the statute uses calendar months, which makes the calculation date-specific rather than a flat count.

Calendar Months, Not Days

Under the Private Housing (Tenancies) (Scotland) Act 2016, the three-month notice period runs from the date the tenant is deemed to have received the statutory Rent-Increase Notice. It expires on the corresponding date three calendar months later.

If the tenant receives the notice on 14 March, the notice period expires on 14 June. The earliest the new rent can take effect is 15 June. The months are measured calendar-to-calendar, so a notice received on 30 November expires on 28 February (or 29 in a leap year) — the last day of the target month.

The 48-Hour Delivery Buffer

The deemed receipt date depends on how you serve the notice. Hand it to the tenant in person and deemed receipt is the same day. Post it or email it and Scottish law adds a 48-hour delivery allowance — two calendar days — before the three-month clock starts running.

This buffer catches landlords out constantly. If you email a notice on 12 February, deemed receipt is 14 February, and the three-month period runs until 14 May. Stating an effective date of 12 May (three months from the send date) gives the tenant grounds to reject the increase.

Two Clocks Running Simultaneously

The three-month notice period is only one of two statutory clocks. The other is the 12-month frequency clock — rent can only be increased once every 12 months from the tenancy start date or the effective date of the previous increase.

Both clocks must be satisfied before the new rent can take effect. If the 12-month anniversary falls after the three-month notice expires, the effective date must wait for the anniversary. If the anniversary has already passed, the effective date only needs to clear the three-month window.

Getting this alignment wrong is the most common reason rent increase notices fail in practice.

What If You Give Too Little Notice?

A notice with an effective date before the day after the full three-month notice period expires is not automatically void. The tenant can return Part 3 of the notice, confirming they are not required to pay the increased rent until the full notice period has actually elapsed. The effective date simply defers to the first lawful date after the three months expire.

But the notice must still comply with every other requirement. If the form itself is incomplete or uses the wrong template, deferral will not save it.

Planning Your Timeline

Count backwards from your target effective date. If you want the increase to take effect on 1 September, the notice must be received by 31 May at the latest. If you are posting or emailing it, dispatch it by 29 May to allow for the 48-hour buffer.

Our Scotland rent increases guide includes a timeline calculator that aligns both statutory clocks and accounts for the delivery buffer, so you can lock down your dates before filling in the prescribed form.
