What moves project budgets most
Labour, prep, removals, access, finish level, and contingency usually move faster than the measured scope alone.
Where people under-budget
Extras, disposal, edge details, and regional labour pressure are commonly missed on early plans.
Before you compare quotes
Write down the measured scope, finish assumptions, and what is excluded so contractor totals are being compared on the same basis.

Use this project hub to brief suppliers or installers
Work through the core calculator first, then use the linked guides and quote checklist to request cleaner, more comparable prices.
- Confirm what the quote should include: materials only, labour only, or both.
- State access, finish level, timing, and any unknowns clearly.
- Ask each supplier or installer to price the same scope and exclusions.
You can also open the wider Project Cost Estimating project hub if the quote depends on more than one material.
