Plumber Price Calculator
From emergency leaks to full boiler installations, plumbing jobs vary wildly in scope. Accurate pricing requires anticipating the unknown—like seized valves and hidden pipework.
Key pricing factors
Emergency Call-outs
Out-of-hours work should carry a premium rate for the first hour to cover disruption and urgency.
Copper & Brass Fluctuations
Copper pipe and brass fittings change in price frequently. Do not rely on memory for material costs.
System Draining
Factor in the hours required simply to drain and refill a heating system before the actual work can begin.
Example: Radiator Replacement
- Labour (3 hours @ £45)
- £135.00
- Type 22 Radiator & TRVs
- £110.00
- Inhibitor & Consumables
- £20.00
- Cost
- £265.00
- Profit Margin (25%)
- £66.25
- Final Quote
- £331.25
Even simple replacements require system draining, refilling, and bleeding, which heavily impacts the labour time.
Practical quoting guidance
- Include a clause for dealing with seized stopcocks or ancient pipework that fails when disturbed.
- For boiler installs, detail the exact model and warranty period in the quote.
- Charge appropriately for the physical difficulty of working in tight lofts or under floorboards.
Frequently asked questions
How do I price bathroom suites?
Break the quote down into strip-out, first fix (pipework modification), tiling/boarding, and second fix (sanitaryware installation).
Do I charge for travel to merchant?
Yes. If a specific part is needed midway through a job, the time spent driving to the plumbers merchant is chargeable time.
