Variation & cost blowout disputes

Being charged for “variations” — extras or changes — you never agreed to, or hit with a final bill far above the contract price? In Victoria, variations to a domestic building contract generally have to be in writing, and a builder who doesn’t follow the variation rules may not be able to recover the extra cost (except with VCAT’s permission). We help you challenge disputed variations and cost blowouts.

Common questions

Good to know

Do building variations have to be in writing in Victoria?

Generally yes for domestic building contracts. A builder who carries out a variation without following the required process may be unable to recover the cost of it, except with VCAT’s permission — so many disputed variations can be challenged.

The final bill is way over the contract price — do I have to pay?

Not automatically. Extras must be properly documented variations, and prime cost / provisional sum items have their own rules. We can review the bill and tell you what is genuinely owed.
