Pricing guide

Costs are driven by where the insulation goes (internal cavity versus external systems), the materials and finishing required, and how much area is being done. Access needs such as scaffolding, after‑hours attendance and regional callout or hourly rates also influence totals, and suspected hazardous materials are usually handled separately. If you mark the area as 'unsure', a conservative mid-range band is typically used for estimating.

  • Wall location and type

    Internal cavity batts are generally simpler than external wall systems, which usually require extra handling and finishing.

  • Material and finishing requirements

    Higher‑performance or specialised finishes for external walls typically increase material and labour needs compared with standard batts.

  • Access and scaffolding needs

    Restricted access, height or the need for scaffolding usually adds complexity and is treated as an additional access factor.

  • Project size and coordination

    Whole‑house or multi‑area jobs often bring modest efficiencies but also add coordination time that can change the overall scope.

  • Presence of hazardous materials

    Asbestos or other hazardous materials are excluded from standard installs and will require separate specialist removal before work can proceed.

Frequently asked questions

Do installers need to be registered?
In this trade installers generally require registration to carry out insulation work. Ask any prospective installer to confirm their registration before booking work so you know they meet local requirements.
How should I prepare the area?
Clear furniture and provide safe, unobstructed access to the walls so installers can work efficiently. If external access or scaffolding might be needed, mention this up front as it is usually treated separately from a standard install.
What if asbestos is found in the walls?
Hazardous‑material removal is excluded from standard insulation work; if asbestos is present you will typically need a licensed asbestos removal specialist before insulation can be installed. Let providers know if you suspect hazardous materials so they can advise next steps.
Will external wall installs cost more?
External wall installs typically require more labour, higher‑spec materials and additional finishing compared with standard internal batt installs. If specialist access or scaffolding is needed, that is usually treated separately and can increase the overall scope.
