Scotland Rent Increase New Rules 2025 and 2026: What Actually Changed

The Housing (Scotland) Act 2025 received Royal Assent on 6 November 2025, but its rent-related provisions do not all switch on at once. Some are already in force, some activated in October 2026, and the most significant changes to rent adjudication are not live until April 2027.

Already in Force: The Framework (November 2025)

The 2025 Act established the statutory framework for local Rent Control Areas across Scotland. It gave Scottish Ministers the power to designate specific postcodes or council areas as RCAs, set the cap formula at CPI plus 1% (maximum 6%), and defined the exemptions for new-build, build-to-rent, mid-market, and long-vacant properties.

None of this has practical effect yet because no RCA has been designated. The framework exists; the mechanism has not been triggered.

April 2026: Local Authority Data Powers

From 1 April 2026, local councils gained statutory powers to collect rental data directly from landlords and tenants within their boundaries. This is the information-gathering phase — councils need market data before they can submit assessment reports to Ministers recommending (or not recommending) RCA designation.

For landlords, this means you may receive formal data requests from your local authority about current rents, recent increases, and property details. These are statutory obligations, not optional surveys.

October 2026: Record-Keeping and Succession Changes

On 6 October 2026, two additional provisions came into force. Landlords now face mandatory record-keeping requirements — maintaining documentary proof of rent levels, notice service dates, and tenancy terms. The same date reduced the qualifying period for PRT succession from twelve months to six months.

The record-keeping duty reinforces something that was already best practice: keeping copies of every Rent-Increase Notice you serve, proof of delivery, and tenant response documentation.

April 2027: The Big Adjudication Changes

Two changes scheduled for 1 April 2027 directly affect the rent increase process:

New challenge process. A tenant who considers the proposed increase above the permitted rate must notify the landlord in writing within 30 days of receiving the notice. If the landlord does not withdraw the notice or agree a compliant amount within 21 days of receiving that notification, the tenant can refer the case to a Rent Officer; the referral must be made within 42 days of the landlord's receipt.

Adjudicator ceiling. Under current rules (pre-April 2027), a Rent Officer or the First-tier Tribunal can set the rent higher than what you proposed if they determine the open market rent exceeds your figure. From April 2027, neither body can set the rent above the amount in your notice. This removes the risk of an upward adjustment but keeps the downward risk if your proposed rent exceeds market value.

May 2027 and Beyond: First RCA Assessment Reports

Local authority rent assessment reports are due to Ministers by 31 May 2027. Ministers can designate Rent Control Areas after reviewing those reports. The Act does not set a date for the first designation.

Until your postcode falls inside a formally designated RCA, the CPI-plus-1% cap does not apply to your property. The statutory rent increase route — prescribed notice, three months' notice, once per year — continues to operate under open-market rules.

What to Do Now

The practical impact for most Scottish landlords in late 2026 is limited. Your statutory obligations for serving a rent-increase notice have not changed since the 2016 Act. What has changed is the recording requirements and the approaching shift in adjudication rules.
