Why professionals use it
Loft Conversion Budget Estimate
Generated the moment your client answers a few questions. No takeoff.
Assumptions made in this estimate
A budgeting estimate, not a fixed quote. Final cost depends on a site survey and final specification.
Every report spells out its assumptions and disclaimer, so it is read as a ballpark, not your promise.
Build cost, contingency, prelims, fees and VAT. The extras clients always forget.
