How these estimates are calculated
Place, currency and tax. Prices are for the UK, in GBP (£). They exclude VAT. Most small trade businesses are below the £90,000 VAT registration threshold and do not charge it. The range is a national average. When you pick your region, the calculator scales the labour share of the range by a local index from 1.00 to 1.25. The calculator does not quote below its minimum price, £50 at the national average.
Where the range comes from. The market range for this job comes from prices published for the UK by marketplaces where customers hire pros and consumer groups. We name these sources by type, not by company. We check the hourly rates against ONS earnings data and the National Living Wage. A trade's rate should sit well above what its workers earn, because it also pays for overhead, travel and insurance.
When we checked. We last checked these rates against their sources on 30 September 2026.
Market price and your price. "What pros charge" is the market range for the job you describe. Your own cost figures do not change it. The table under it, "Your costs at this price", uses your figures: time on the job, labour cost, materials, equipment, travel, fees and overhead. Profit is the market price minus those costs. If no market range covers the job, the calculator prices it from your costs instead: your costs plus overhead, then your target margin or markup.
Plumbing quotes go wrong when the price is set before the access is understood. The calculator above builds the
number from UK price bands for the job and moves it with what it takes to reach the work. Your hours and your own
rate then show what that price leaves you.
How the calculator works
- Pick the job. Drain unclogging, faucet (tap) replacement, leak repair, toilet installation, water
heater installation, or Custom job when you want to price purely from your costs.
- Say how hard it is to reach. Open and easy, a tight spot, or behind a wall and under a floor — the same
job at the far end of that list is a different number of hours.
- Scope and timing. One fixture or several, and an emergency or out-of-hours call, which multiplies the whole
band by one and a half, parts included. Your labour cost rises by the same factor.
- Your region. Rates are adjusted by a regional labour index across six regions — National average, London,
England outside London, Scotland, Wales and Northern Ireland. London runs above the rest.
- Check what you keep. Open “Your costs and margin” for the hours, parts, the trip and the profit at that
price. Replace the prefilled costs with your own numbers.
What UK plumbers charge for their time, 2026
| Basis | Published UK figure |
|---|
| Standard hourly rate | £40–£60, average £50 |
| Apprentice, per hour | £15–£25 |
| Experienced plumber, per hour | £60–£80 |
| Minimum charge | One hour, £50 |
| Emergency call-out | £100–£120 |
All figures are before VAT. The hourly rate is the firmest number in British plumbing — two independent guides
print it identically — so use it as the check on every quote: divide the price by the hours and see whether you
land inside £40–60.
Worked example
A blocked waste pipe under the suspended floor of a Victorian terrace. Choose the job, then set access to
“behind a wall, under a slab or floor”: the hours rise, and the quote rises with them. Add the scope if more than one fixture is affected, and
tick the emergency toggle if the call came in on a Sunday. Then open “Your costs and margin” — the panel shows
the hours, your parts, the trip and the margin. Divide the price by the hours before you send it: if the implied
rate is under £40 the job is underpriced, and if it is well over £60 you need a reason a client will accept.
Quoting plumbing work in the UK
- Quote the diagnosis separately. A minimum that covers the first hour and is credited against the repair is
easier to sell than a free visit you end up paying for.
- Write the exclusions down. Making good after opening a wall, and the notifications and inspections some
work requires, are the two things clients assume are inside the price.
- Charge properly for out of hours. A Saturday night call is worth more than a Tuesday morning one, and
British clients expect to be told so up front rather than discover it on the invoice.
- Keep gas work out of this. Boiler and gas appliance work needs the right registration and its own pricing.

Frequently asked questions
What do plumbers charge per hour in the UK?
Two independent UK trade guides print the same range: £40–60 an hour, with £50 the average. One of them splits it by experience — an apprentice at £15–25, a competent plumber at £40–60 and an experienced one at £60–80. London sits at the top. All figures are before VAT.
Should I charge a call-out fee?
Charge a minimum rather than a call-out fee for ordinary work. UK guides put the minimum at one hour of work, which is £50 at the average rate, and an ordinary visit bills by the hour from there. The £100–120 call-out charge you will see published is for emergencies: the guide that prints it says plumbers mostly charge just for turning up when the call is out of hours.
Do I have to charge VAT?
Only once your taxable turnover passes £90,000 in any rolling twelve months — then registration is compulsory and you add 20% to labour and parts on every invoice, except on energy-saving materials such as heat pumps, which VAT Notice 708/6 zero-rates until 31 March 2027. Below the threshold you do not add VAT, and you cannot reclaim the VAT on the parts you buy either. The calculator quotes before VAT.
Water heater installation — does that mean a cylinder or a boiler?
In Britain it means whichever one you are fitting, and they are not the same job. A hot water cylinder swap and a combi boiler installation carry different hours, different parts and different regulatory work, and no UK price guide separates them cleanly. Price this one from your own hours and your own parts bill rather than from the band.
Where does the number come from?
From UK trade guides. Each job type carries a band in pounds for the finished job, parts included, and six of the seven bands are read from the guides. The water heater band is the exception: no guide prints the whole job, so it is the fitting hours a guide prints at £40–60 an hour plus a cylinder at retail price. Access and scope move the quote up the band, an emergency call multiplies it by one and a half, and your region scales the labour part. Your hours and your own rate do not move the price. They show what it leaves you.
How much should I mark up parts?
No UK guide publishes a plumbing parts markup, so this is your decision. Standard parts for a job already sit inside the band the calculator shows; when the parts bill is unusual — a specified boiler, a long run of pipe — switch the job type to Custom and price the whole thing from your costs instead.
