ACT Lease Type and Insulation Compliance Deadlines: Periodic vs Fixed-Term Tenancy Rules

The Deadline Depends on Your Lease, Not Just the Calendar

ACT landlords know that ceiling insulation must meet R5 (or an existing R2 minimum), but many don't realise the compliance deadline isn't one fixed date for everyone. The Residential Tenancies Regulation 1998 ties the timeline to your tenancy type and when the agreement was signed. Whether your property is on a fixed-term lease, a periodic tenancy, or about to be re-let changes when the clock starts — and how long you have.

Three Deadline Pathways

The regulation created a phased system that started on 1 April 2023. Here's how each pathway works:

1. New lease signed between 1 April 2023 and 30 November 2026 Every new residential tenancy agreement signed during this window triggers a 9-month compliance period. The clock starts the day after the agreement is executed. If your property lacks insulation or has insulation rated below R2, you have exactly nine months from that date to upgrade to R5 or obtain a valid statutory exemption.

This applies whether the new lease is a first-time let, a re-let to a different tenant, or a fresh fixed-term agreement with the same tenant. The key word is "new agreement" — not "new tenant."

2. Continuous tenancy that predates 1 April 2023 If your tenant has been in the property under an ongoing agreement signed before 1 April 2023 — whether that's a rolling periodic tenancy or a fixed-term lease that keeps renewing — the backstop deadline is 30 November 2026. No ifs. The property must be fully compliant or hold a valid exemption by that date, regardless of lease renewal status.

3. Any new lease signed from 1 December 2026 onward From this date, the permanent rule kicks in: compliance within three months of executing the tenancy agreement. The transition period is over. Three months is significantly shorter than nine, so landlords who've been deferring will face a tighter window.

The Periodic Tenancy Trap

Some ACT landlords have deliberately avoided signing new fixed-term leases, letting existing agreements roll onto periodic terms to sidestep the 9-month trigger. Community forums confirm this is a conscious strategy — avoid signing anything new, and the compliance clock doesn't restart.

It works, but only until 30 November 2026. Every property under a pre-April-2023 periodic tenancy hits the backstop deadline regardless. And from 1 December 2026 onward, even a periodic tenancy that transitions to a new fixed-term triggers the three-month rule.

The strategy also carries a practical risk: if the tenant leaves and you need to re-let, the new agreement triggers an immediate compliance countdown. Rushing an insulation upgrade while managing a vacancy isn't ideal.

What Counts as a "New Agreement"?

This is where landlords frequently trip up. Under the regulation, each of the following counts as a new tenancy agreement that restarts the compliance clock:

• A brand new lease with a different tenant
• A new fixed-term lease signed with the same tenant (not a simple rollover)
• A formal lease renewal that requires fresh signatures

What doesn't trigger it: an existing fixed-term lease that automatically converts to a periodic tenancy at expiry without new paperwork, or a periodic tenancy that simply continues month-to-month.

Practical Timeline: What to Do Now

If you're approaching any of these deadlines, the compliance sequence takes time to arrange:

1. Ceiling insulation assessment — determine your current R-value
2. Licensed electrician inspection — mandatory pre-installation electrical safety check (this alone can take weeks to book in peak periods)
3. Approved installer engagement — must be EEC-certified
4. Installation and documentation — insulation compliance certificate, electrical reports, updated insulation statement

In a tight Canberra market, electricians and insulation installers can have booking lead times of four to six weeks. Starting nine months before your deadline is comfortable. Starting three months before — which will be the permanent rule — is tight.
