Ceiling insulation: costs and options
Ask for a roof-space inspection before ordering batts. An installer should identify the existing insulation, access, downlights, wiring, flues and any damp or damaged material.
What to include in the scope
Compare batts and blown-in insulation by installed R-value and how continuously the installer can cover the ceiling. Measure the accessible ceiling in square metres and request separate prices for old-material removal, tricky eaves and access hatches. Use appropriately qualified trades for electrical hazards.
Roof spaces contain electrical and heat hazards. Follow applicable safety standards and engage qualified installers where needed.

Build your budget
Adjust the quantities and unit rates. This is a planning tool, not an installer quote.
Use local itemised quotes as the starting rates. Freight, labour availability and minimum call-out charges can change the total by location. Enter GST-inclusive rates where available and list removal, disposal and access separately when excluded.
Ask before you accept a quote.
- Will the quote identify areas you cannot reach, and will you provide photos and the installed product specification after the job?
- Is GST included, and is the price fixed or estimated?
- Are removal, disposal, access and making-good included?
- What changes would trigger extra costs, and who approves them?
- What is the warranty on products and workmanship?
