Knowing how to price plumbing jobs consistently makes a big difference to profit and to how customers see you. Plumbing and heating work ranges from a ten-minute tap washer to a full bathroom or boiler replacement, and each needs a different approach.

This guide gives a method, not market rates. Your prices depend on your costs and area.

## Small repairs and call-outs

For small jobs (leaks, taps, toilets, radiators), many plumbers use:

- a **minimum charge** or first-hour rate that covers travel and setup;
- then a rate per additional hour or part hour;
- plus parts at cost plus a margin.

For emergency and out-of-hours work, a higher rate or call-out fee is normal. Say so clearly before you go. See [call-out charges and minimum charges](https://roughfigure.com/blog/call-out-charges-and-minimum-charges).

## Fixed prices for common jobs

Customers like fixed prices. For jobs you do often, such as replacing a tap, toilet or radiator, work out your average time and parts, then set a fixed price. It makes quoting quicker and customers trust it.

## Bathroom installations

Bathrooms are bigger projects with many parts:

- strip-out and waste;
- first fix and second fix plumbing;
- electrics, tiling, plastering and joinery, if you include them;
- sanitaryware and fittings, supplied by you or the customer;
- days on site.

Be clear about what’s included and who supplies what.

## Boiler and heating work

For boiler replacements and heating upgrades, price the boiler, flue, controls, system cleaning, any pipework changes, labour, and commissioning and paperwork. Gas work must be done by a registered or licensed gas engineer (in the UK, a Gas Safe registered engineer), so make your registration or licence clear to customers.

## Parts and materials

Decide your margin on parts and be consistent. If customers supply their own parts, say whether you’ll guarantee them.

## Give a ballpark price online

Many plumbing customers want to know roughly what a job will cost before booking. A ballpark range for common jobs, or an [instant estimator](https://roughfigure.com/blog/instant-quote-calculator-for-your-website) on your website, answers that out of hours and brings in better enquiries.

## Questions

### Should plumbers charge a call-out fee?

Many do, especially for emergency or out-of-hours work. Others use a minimum charge instead. Either way, tell customers before the visit.

### Should I give fixed prices or hourly rates?

Fixed prices for common, predictable jobs; hourly rates or estimates for diagnosis and unpredictable repairs.

### How do I price a bathroom installation?

Break it into strip-out, plumbing, other trades, materials and days on site, then add overheads and profit. See [how to price a job](https://roughfigure.com/blog/how-to-price-a-job) and [how to write a quote](https://roughfigure.com/blog/how-to-write-a-quote).
