Checked 5 November 2026. For owners of residential rental property in the Australian Capital Territory.
Can you find the document that shows your rental property’s ceiling insulation rating? With the ACT’s phase-in period ending on 30 November, now is a useful time to check the evidence with your property manager.
This is an approaching deadline under an existing standard, not a newly announced rule. The standard began on 1 April 2023. Your property’s tenancy history and any valid exemption affect when it must comply.
First, check the property’s actual deadline
The ACT Government’s landlord factsheet identifies 30 November 2026 as the end of the phase-in for most existing rentals, subject to exemptions.
Check the timing rather than relying on a general grace period. The official factsheets and current Residential Tenancies Regulation, section 10, describe some transitional dates differently. This article therefore does not calculate a deadline for a particular tenancy.
Confirm your property’s actual deadline with the ACT Government or a qualified adviser, using its full tenancy and exemption history. Do not assume a new lease restarts the clock or that 30 November grants extra time if an earlier deadline already applies.
R2 and R5 mean different things
Under sections 8 and 9 of the regulation, ceiling insulation already rated at least R2 on 1 April 2023 can meet the standard. If an upgrade is needed because insulation is missing or below R2, the required rating is at least R5 unless an exemption applies. Ask a suitably qualified professional to assess the property.
The ACT Government’s evidence guidance lists installer reports and receipts identifying the R-value among possible records. Keep evidence supporting any exemption too. Do not infer compliance from a building’s age or an invoice that simply says “insulation”.
Build a small evidence file
Use these headings as an organising checklist, not a substitute for a professional assessment:
- Property and timing: address, relevant lease dates, confirmed deadline and who is arranging the next step.
- Assessment: the existing report or other evidence, what it says about the insulation and any unanswered questions.
- Work: quotes, agreed scope, booked dates, completion documents and invoices. Keep a quote separate from proof that work happened.
- Payment: who paid, the payment date and the matching owner-statement line or bank record. Keep the original invoice as well.
- Exceptions and follow-up: the basis and supporting documents for any exemption, plus a review date where it is temporary.
Give each file a clear property-and-date name. A folder with a paid invoice but no assessment or completion evidence still has an open question. Ask for the missing document rather than marking the whole job complete.
If new insulation is required
The ACT guidance requires a licensed electrician’s safety inspection before installation, completion of necessary electrical work, and a certified insulation installer.
Under sections 10 and 12 of the regulation, the records include a required electrical work report and, where work was needed, a completed electrical work report. Ensure the installer receives the relevant reports before any removal of lower-value insulation or installation work begins. Keep the Certificate of Electrical Safety where electrical work occurred.
Let qualified professionals assess the roof space and installation; this checklist is not a DIY inspection guide.
For apartments, read the strata guidance with your manager. Lower-floor apartments and top-floor work have different considerations. Keep owners-corporation correspondence and relevant permissions with the property file.
Keep costs and evidence connected
If your manager pays for the work, compare the statement charge with the invoice and completion documents. If you pay directly, keep that expense alongside your other property costs so it is not overlooked or counted twice. Ask your accountant about tax treatment rather than assuming every upgrade is immediately deductible.
PropAlly can help organise property income and expenses while you keep your existing manager. Review extracted statement figures against the original before saving them, and keep the full compliance evidence accessible. Software does not certify that insulation meets the standard.
