Tradesman billing unreasonable fees
<p>What prevents a tradesman from billing a client an unreasonable fee after the work is done? For example, a plumber may quote provisionally £100 verbally (or not even give a cost estimate as is common here in the UK), do the work, then invoice £10,000 for a minor job that took maybe an hour. What consumer protections are in place for a case like this?</p>

<h2>The law</h2>
<p>It’s a long-standing tenent of contract law that, where a price has not been agreed, a reasonable price is to be paid.</p>
