48-Hour Delivery Rule for Rent Increase Notices in Scotland

Most Scottish landlords know they need to give three months notice before a rent increase takes effect. Fewer know about the 48-hour delivery allowance that shifts the entire timeline by two days — and that miscounting those two days can hand the tenant grounds to reject the increase outright.

What the 48-Hour Rule Actually Says

Under Section 62 of the Private Housing (Tenancies) (Scotland) Act 2016, when a statutory Rent-Increase Notice is served by post or electronic communication (email), the tenant is deemed to have received it 48 hours — two calendar days — after dispatch.

The three-month notice period does not start running until that deemed receipt date. So a notice emailed on 10 January is treated as received on 12 January, and the three calendar months run from 12 January to 12 April.

Hand delivery is the exception. If you give the notice directly to the tenant in person, deemed receipt is the same day, and the three months start immediately.

The Three Valid Service Methods

Scottish statute recognises three ways to serve a Rent-Increase Notice:

Personal delivery — handing the notice directly to the tenant. Deemed receipt is instant. No buffer applies, but you should ask the tenant to sign and date an acknowledgment of receipt.

Post — sending the notice by recorded delivery or standard post to the let property address. The 48-hour buffer applies from the date of posting.

Email — sending the notice as an attachment to the tenant's email address. This method is valid only if the written PRT agreement contains an explicit clause where the tenant consents to receiving statutory notices by email. If there is no electronic communication clause in the tenancy agreement, email service is legally void — even if you and the tenant email each other about the property every week.

SMS, WhatsApp, tenant portal messages, and online letting agency chat tools do not count.

How Miscounting Costs You Three Months

Suppose you email a notice on 14 February with an effective date of 15 May. You have calculated three months from your send date: February to May. But deemed receipt is 16 February, so the three-month period actually runs to 16 May. The earliest lawful effective date is 17 May, so 15 May is two days too early.

The tenant can return Part 3 of the notice, confirming they will not pay the increased rent until the full notice window has elapsed. The effective date defers to 17 May. In practice, many landlords re-serve the notice entirely, which restarts the clock from scratch.

What Proof to Keep

For every notice you serve, keep evidence that would hold up if the tenant later refers the increase to Rent Service Scotland:

• Post: certificate of posting, Royal Mail signed-for tracking confirmation, and a copy of the notice
• Email: sent-mail log showing the recipient address, timestamp, and attached PDF; delivery or read receipt if available
• Hand delivery: a signed, dated acknowledgment of receipt from the tenant

Joint Tenants: Separate Notices

If the tenancy names two or more joint tenants, each one must receive their own copy of the notice. For tenants at the same address, post separate envelopes or send individual emails. The 48-hour buffer applies to each dispatch independently.

Build the Timeline Correctly

The 48-hour rule interacts with both the three-month notice period and the 12-month frequency clock.
