How to Price Jobs as a Plumber
A Clear UK Guide to Call-Out Fees, Quotes, Materials Markup, VAT, and Avoiding Underpricing

Plenty of plumbers are booked out every week and still cannot explain where the money went. The problem was never a shortage of work.

This book was written for UK sole traders, subcontractors, and small plumbing businesses who want a clear, honest answer for why the diary is full and the bank account still feels tight. It walks through exactly where profit quietly disappears across an ordinary week of domestic jobs, and what to do differently starting with the very next quote.

Written in plain English, this book breaks down how a plumbing job should actually be priced from the ground up. You will learn how to work out your true running costs, build a call out fee and hourly rate that genuinely cover them, price materials with a real markup instead of a guess, and charge properly for evening, weekend, and emergency work without the guilt that usually gets in the way.

Inside, you will learn:

• Why being busy every week says nothing about whether the business is actually profitable
• How to calculate the minimum an hour of your time must earn before a single pound of profit exists
• The real difference between a materials markup and the profit margin it actually produces
• How to charge for emergency, evening, and weekend callouts with confidence instead of quiet guilt
• How to handle a hidden fault or a scope creeping mid job without losing the price you started with

The book covers every major pricing method used in domestic plumbing work, hourly, day rate, fixed price, and diagnostic pricing, and explains, without hedging, which jobs suit each one and what happens financially the moment the wrong method gets used on the wrong job.

This is not a theory book, and it is not a stack of blank invoice templates either. It is a working system, built job by job from the first phone call to the final invoice, designed to stop unpaid extras, underpriced callouts, and the slow, invisible leak of profit that keeps too many good plumbers permanently busy and permanently short of money.

Read this if you are ready to charge what the job is actually worth, keep the profit you have already earned, and run a plumbing business that holds up long after the busy season ends.
