How do I choose a business coach for my plumbing business?

Why does a checklist of soft skills miss the real test?

Most advice on choosing a coach for a plumbing business talks about communication style, how approachable someone is, or how many testimonials they have. None of that tells a plumber whether a quoted job will actually leave a decent gross profit margin after the pipe, the parts and the labour are paid for. A coach who never asks about that gap is only testing for a nice chat, not for the one number that decides whether the business is profitable.

A plumber walking into a hot water replacement or a bathroom renovation already scans for the corroded fitting, the seized isolation valve, the backflow device that will fail its next compliance check. The customer never notices any of it. Many coaches never ask about this skill at all, so the business never gets pricing discipline built around it. Instead, generic coaching treats every callout the same and pushes for more leads rather than better margin on the jobs already on the books.

What happens when a coach does not understand where plumbers lose margin?

Without understanding where margin leaks out of a plumbing business, a coach keeps pushing for more jobs on the board while work that should stay in house, like gas fitting, backflow testing or compliance certification, gets handed to a subcontractor at full retail. The business does the selling and the risk, and someone else keeps the markup.

Picture a plumber who quotes a straightforward hot water unit swap, then finds on site that the isolation valve is seized and the backflow prevention device has never been tested. If gas work or compliance testing always goes to an outside trade, that extra value walks out the door with the sub-contractor's invoice. A business running as a general manager, working in the business day to day, needs different coaching to one ready for a leadership and expansion phase, where the decision is whether to bring related trades in house at wholesale instead of losing margin to someone else's markup. A coach who gives the same advice regardless of stage is the opposite of what a growing plumbing business needs.

What should you ask before you sign up with a coach?

Ask a prospective coach how they would price a typical job in your business, whether they start from your own quotes and invoices or a generic workbook, and whether they can tell you what stage your business is at. Their answer tells you fast whether they coach your plumbing business or coach businesses in general.

Ask what they would do with a hot water callout that turns into a compliance issue once the isolation valve and backflow prevention are checked. Ask how they handle a bathroom renovation quote that has sat unconverted for weeks: do they talk margin, or just talk follow-up emails. Greg Allan, who built his own trade business before coaching plumbers and other trade owners, tests for exactly this: whether a coach can see the margin on the job, not just count the hours worked. Ask too whether they have actually run a trade business, whether they work on root causes with systems rather than handing out worksheets, and whether “hire someone” is their answer to every problem.

How do you know a coach can turn your eye for extra work into higher margin?

You already know how to read a job. The customer called about a blocked drain, but you can see the ageing stack pipe, the missing isolation valve, the backflow device due to fail its next test. A coach who will not help you turn that into a value-based quote, offering options and pricing for the expertise, not just the callout, is only coaching you to stay busy.

Value-based pricing for a plumber means scanning the whole job, not just the ticket item, and putting real options in front of the customer so the price reflects risk avoided and expertise delivered. A coach worth paying should also push you to show real finished work, including a job that could have gone badly wrong if it hadn't been caught, because that visible proof is what lets a customer accept a price built on expertise rather than labour alone.

What should a coach do with your own data and office work?

A coach worth paying works from your own job data first, not a generic questionnaire, and should show you where AI agents, software that does office work the way you'd do it yourself, with your prices, your wording and your rules, can take logging callouts, chasing signed quotes or tracking compliance certificate renewals off your plate.

Plumbing businesses carry a lot of non-billable admin: maintenance contracts with strata and property managers, compliance certificates, emergency callout logs. None of it pays directly, but all of it has to be right. This is a data first way of coaching, starting from the numbers already sitting in your quotes and invoices rather than from how the business “feels”. Coaches who understand AI agents across many trades are often quicker to spot what's normal for a plumbing business and what isn't, because the pattern shows up in the data before it shows up in the bank balance.

What are the warning signs of a coach who will just keep you busy?

The warning signs are a salesperson leading the first conversation instead of a tradesperson, a coach who has never run a trade business, and advice that reads the same whether the business is a plumber, an electrician or a shop fitter. Watch for anyone whose answer to every gap is to hire more staff.

A coach who never asks to see a real quote, a real job cost or a real margin is coaching in the dark. If every session starts with the owner explaining the business again rather than starting from the numbers, the coaching is working from an old picture, and an old picture is usually the one that got the business into the gap in the first place.

How does Data First Coaching approach this?

Data First Coaching starts the same way for a plumbing business choosing a coach: it looks at the quotes going out, the jobs that converted and the margin on each, before anyone talks about communication style or marketing. Greg Allan, who built his own trade business before coaching plumbers and other trade owners, puts it simply: “You know what you're looking at and the customer doesn't.” The Trade Business Intelligence reads that data alongside years of coaching trade businesses, so the coaching starts from numbers rather than the plumber explaining the business again. The how, matching the right next step to the business's actual stage, is worked through inside the Academy, with members who are open minded, innovative and willing to share, because the Trade Business Intelligence is powered by every member.
