When you engage a builder, electrician, architect, or another contractor to carry out work on your property, you expect the agreed price to be fair and final. But what happens when the final invoice is far higher than the original quote?
Unexpected cost increases can be frustrating and sometimes feel unfair. Understanding your rights and the difference between a quote and an estimate can help you resolve the issue confidently and protect your position.
If you accepted a fixed quote, the contractor generally cannot increase the price without your express consent.
In some situations, the contractor may be able to increase the cost but only if certain conditions are met:
However, if the contractor simply increases the price because their costs went up, for example due to higher material costs, but did not agree this with you or get your consent, then you may not be legally obliged to pay the extra.
Your rights depend on whether you are a consumer (i.e., a homeowner contracting work for personal use) and the date the contract was entered into. Some key legal frameworks:
In practice, this means:
Understanding these rights can help you challenge excessive or unexpected costs and encourage a swift, fair resolution.
Construction and home improvement disputes can be complex: issues around contract interpretation, scope of work, quotes vs estimates, implied statutory terms, and consumer rights all interplay. An experienced construction or dispute resolution lawyer can help you:
At Hegarty, our team has years of experience in construction disputes, and we offer clear, practical advice to guide you through your options.
If your contractor’s final invoice exceeds the agreed price and you did not authorise the additional costs, contact Hegarty for a free initial assessment. We will help you understand your rights and the most effective way to resolve the dispute.
If you truly accepted a fixed quotation (and no valid variation was agreed by you), you are ordinarily not obliged to pay the extra. The contractor should have raised the issue before you agreed to the extra work.
Since an estimate is not binding, you may have fewer protections than under a fixed quote. However, you still have rights: the service provider must charge a reasonable amount for the work done; if the charge is grossly higher without justification, you may challenge it.
You may withhold payment for the disputed portion, but you should proceed cautiously: if you withhold the entire balance and the contractor claims you are in breach, you might be exposed to counter-claims. It’s wise to notify the contractor you dispute the extra portion and seek legal advice first.
No, many of the consumer protections apply specifically to contracts between a business and a private consumer. Business-to-business contracts have different rules and protections, and the terms of the contract become particularly important.
