If a new finding changes the agreed scope, pause the affected work and ask what was found, what it means, and which options are available. Confirm any added cost and timing before approving extra work, and keep the revised scope in writing.

What can change the scope?
A hidden leak, damaged pipe, blocked section or access issue may not be visible before work begins. The important distinction is what has been observed, what remains uncertain and whether the original repair will still solve the problem.
How to decide what happens next
Ask for the finding to be shown or described, the effect on the original plan, and the practical options. Confirm which work is urgent, what can wait, and the price and timing for each agreed option before work moves beyond the existing scope.
Keep the change clear
Record the revised work, agreed price or pricing basis, and any exclusions by text, email or updated quote. If the issue involves a gas smell, active leak or immediate safety concern, move to a safe place and follow the relevant emergency guidance first.
When should you call a plumber?
- The new finding affects a different fixture or part of the property.
- The proposed work or price differs from what you agreed.
- You need to understand which part is urgent and which can wait.
- A gas smell, significant leak or other immediate hazard is present.
What affects the cost?
Additional cost can reflect extra diagnosis, access or removal work, parts and labour, making good, and coordination with other trades. Ask for the changed work to be scoped separately, including exclusions, before deciding whether to proceed.
