What a good builder lead actually costs in 2026

Start with the job, not the lead

A kitchen renovation, an extension or a pool is worth tens of thousands of dollars. A lead is only the first step towards one. A lead that costs $40 and never answers the phone is more expensive than a lead that costs $140 and books a site visit.

The maths that matters

Here is a simple example. The figures are illustrative, to show the method, and are not a benchmark.

• You spend $3,000 in a month and receive 30 enquiries. That is $100 per enquiry.
• Ten of them are genuine quote requests and two become jobs worth $25,000 each.
• Your cost per booked job is $1,500, against $50,000 of work.

Now imagine a cheaper campaign that produces 60 enquiries at $50 each, but only three real quote requests and no jobs. The cost per lead looks better and the result is far worse.

Four numbers worth tracking

• Cost per enquiry: what you pay for each form, call or message.
• Enquiry to quote rate: how many enquiries are real, in your area, and the right size of job.
• Quote to job rate: how many quotes you win.
• Cost per booked job: the number that decides whether the ads are working.

Why costs vary so much

Trade, suburb, season, the type of work (urgent or planned), the quality of the landing page and how quickly you respond all move the numbers. That is why a single industry average is rarely useful for your business.

What good looks like

Work out what you can afford to pay for a job based on your margin, then judge every campaign against that number. A good month is not the cheapest month; it is a steady flow of the right enquiries in the right suburbs at a cost per booked job you are comfortable with.
