What should the quote include?
Ask about measurement, cutting, fitting and weather sealing.
Which charges need a closer look?
Check custom glass, wall repairs, wiring for powered models and disposal.
Have the provider mark each item as included, optional or charged separately. An item left blank is a question to resolve, not something to count as free.
Before you decide
Confirm the intended size and location before buying the unit. Compare the complete installation and ask whether any property permissions are needed.
Compare the total you would pay
Put the offers side by side using the same work, dates and quantities. Add required extras and applicable taxes to each starting price. Keep optional upgrades separate so you can choose them deliberately.
- For an hourly price: ask about minimum time, the expected hours and approval before the bill grows.
- For a package: ask about its limits, expiry and the price of work outside it.
- For a deposit: confirm whether it counts toward the total, when the balance is due and what happens if you cancel.
Keep the agreed price and work list together. If the plan changes, ask for the revised total before agreeing to the extra work.
