Before you set the budget

Three decisions that protect your renovation budget

Define the same scope

Write down demolition, retained items, service moves, finishes, approvals and exclusions so every comparison covers the same work.

Separate allowances from fixed prices

Track provisional sums and prime-cost items separately. These are common sources of budget movement after work starts.

Hold a risk reserve

Keep the difference between the central and high estimate visible until access, structure and concealed conditions are confirmed.
