What plumbers actually charge in the UK in 2026
Start with the market, because you do need to know it, then we move past it fast.
Here is the rough shape of UK plumbing pricing in 2026, pulled from the main cost guides customers read before they call you.
| Type of work | Typical rate 2026 |
|---|---|
| Standard domestic hourly, national average | £45 to £75 per hour |
| North of England and Wales | £35 to £60 per hour |
| London and the South East | £65 to £105 per hour |
| Day rate, domestic | £200 to £350 per day |
| Day rate, commercial or specialist | £300 to £450 per day |
| Emergency or out of hours | £80 to £150 per hour |
| Call out or minimum first hour | £60 to £120 |
Those figures line up with what the public sees on the Checkatrade plumber cost guide and the other price guides that rank for this search. They are accurate enough as a market picture.
They are also close to useless to you as the person under the sink. Every one of those numbers answers the customer's question, which is what will a plumber cost me. It does not answer your question, which is what do I need to charge so I am not quietly working for less than minimum wage by the time the year is out. Those are not the same number. They are not even close.
Why the market rate is the wrong place to start
The going rate is a price customers pay. It is not money you keep.
Out of every hour you bill at £60, you do not bank £60. You bank what is left after income tax, National Insurance, the van, the diesel, the press fittings stock, the leak detector, the insurance, the scheme membership, the accountant, and the hours that week you worked but could not put on an invoice. By the time all that comes off, a £60 hour is worth a lot less than £60, and most people who have just gone out on their own have never worked out how much less.
How much you keep also depends on how you are set up. A sole trader and a limited company keep very different slices of the same turnover once tax is in the picture, which is the sole trader vs limited company question. Picking your hourly rate by copying the going rate is like quoting a bathroom by guessing. You would never do that on a job. Do not do it with your own pay.
The right way round is to start from the money you want to take home, then work backwards to the rate that delivers it.
The billable hours trap
This is the one that catches almost every newly self employed plumber, and it is worth slowing down for.
There are about 2,080 working hours in a full time year. Most people, asked to set an hourly rate, quietly assume they will bill most of those. You will not. Not even close.
You do not bill the hours you spend quoting bathrooms. You do not bill the drive between jobs, the trip to the merchants for a single fitting, the half day waiting on a boiler delivery, the evening doing invoices, the Saturday chasing the customer who has gone quiet. You do not bill the 5.6 weeks of holiday and bank holidays an employee gets and you quietly skip, the week you were off with a bad back from lifting a cast iron radiator, or the day you lost to your WaterSafe assessment or your Gas Safe renewal.
Add it up and a solo domestic plumber bills somewhere between 1,000 and 1,300 hours in a year, not 2,080. The admin alone is a big chunk of it, which is exactly why doing your invoices on a Sunday quietly costs you money. Every hour in that unbilled pile still has to be paid for. It gets paid for by the hours you do bill. Which means your rate has to carry the cost of the hours it cannot.
Work out your own number in five steps
Here is the maths the cost guides skip. Use round numbers and your own figures. This is a worked example, not a promise, and your numbers will be different.
Step 1. Decide your target take home. What do you actually want in your pocket for the year, after everything. Say £38,000. Pick your own.
Step 2. Gross it up for tax and National Insurance. To take home roughly £38,000 as a sole trader you need to make somewhere around £50,000 in profit, give or take, before income tax and Class 4 NI. The exact figure depends on your structure, which is the sole trader vs limited company question again.
Step 3. Add your business overheads for the year. A fairly lean solo plumber setup looks something like this:
| Overhead | Rough annual cost |
|---|---|
| Van: lease or finance, fuel, insurance, servicing | £6,000 |
| Tools, press tooling, leak detection, drain camera, calibration | £1,800 |
| Public liability and professional indemnity insurance | £500 |
| WaterSafe or APHC membership, CIPHE if you carry it | £350 |
| Gas Safe registration if you are also a gas engineer | £500 |
| Training, CPD, unvented and water regs refresh | £400 |
| Accountant | £900 |
| Phone, software, and general admin | £700 |
| Total | about £11,150 |
Call it £11,000 if you are plumbing only. About £11,500 if you also hold Gas Safe and do the boiler work. Strip the Gas Safe line if you only run plumbing.
Step 4. Add it together. £50,000 of profit plus £11,000 of overheads means you need to invoice about £61,000 in the year just to land where you wanted to be.
Step 5. Divide by the hours you will actually bill. Not 2,080. Use a realistic billable figure.
| Billable hours in the year | Rate to hit £61,000 |
|---|---|
| 1,400 hours (very busy, good systems) | about £44 per hour |
| 1,200 hours (steady solo year) | about £51 per hour |
| 1,000 hours (quiet patch, lots of small jobs) | about £61 per hour |
Look at what that table is telling you. The £45 your mate down the pub quoted only works if you bill 1,400 hours, which a solo domestic plumber almost never does once quoting and admin and the merchant runs are counted properly. At a realistic 1,200 billable hours, your floor is closer to £51 an hour, and that is before you have made a penny of profit above the wage you set yourself. Charge £40 an hour and you are not running a cheap business. You are running it at a loss and paying for the privilege out of your own time.
If the maths shape feels familiar, it is. The electrician working out lands in the same place, because the costs that catch a self employed sparky catch a self employed plumber for the same reasons.
The employed benchmark you have to beat
Here is the sanity check that stops you underpricing.
A qualified plumber on the nationally agreed rate earns about £21.61 an hour as a technical plumber under the JIB-PMES National Working Rule Agreement in 2026, with trained plumber grades sitting a few pounds below that. Those are the figures set in the JIB-PMES 2026 to 2027 wage agreement. On top of that hourly rate the employed plumber gets holiday pay, sick pay, and a pension paid in by the employer, and they go home at four with none of the admin.
Now run your own number through the maths above. If your rate, after the van and the tax and the unbilled hours come off, leaves you taking home less per hour than the employed plumber with a P60 and a pension, something is wrong. Going out on your own is supposed to come with a premium for the risk and the paperwork, not a pay cut you never noticed. If your figure does not clear the employed benchmark comfortably, your rate is too low. Put it up.
Hourly, day rate, or priced work
Once you know your number, you still have to decide how to charge it.
Hourly suits small jobs where nobody knows how long it will take. A leak you cannot see, a tap that drips and might be the cartridge or might be the seat, a customer who says can you just take a look. Put a minimum first hour or a call out charge on these. The £60 to £120 first hour is not greed, it covers the drive and the slot you cannot now sell to anyone else.
Day rate suits predictable full days, bathroom rip outs, boiler swaps where you know the prep, and subbing for a contractor. Simpler to quote, simpler for the customer. Make sure your day rate, divided by the hours you are actually on site rather than out of the house, still clears your hourly number. A £350 day for eight billable hours is £44 an hour. A £350 day for six is £58. The customer sees the same number. Your bank does not.
Priced or fixed work is where the money is once you are quick and accurate at quoting. Full bathroom installs, central heating swaps, and en suite jobs reward the plumber who quotes well and works clean. You quote a price, you beat your own estimate by being good at the job, and the upside is yours instead of the customer's. The bottleneck is almost never the pipework. It is how fast you can get an accurate quote out the door.
Charging the right rate only works if you actually collect it
You can do all of this maths perfectly and still end up underpaid, because the rate on the quote is not the rate that hits your bank.
The bathroom that finishes Friday and gets invoiced the following Wednesday. The boiler service invoice that sits unpaid for six weeks while you feel rude chasing it. The small leak job you did as a favour and never billed at all. Every one of those drags your real hourly rate below the careful number you just worked out. The hours you do not invoice, and the invoices you do not chase, are exactly the leak that turns a £51 an hour business into a £38 an hour one without you ever changing your price.
That is the part Vanly is built for. You speak the job into your phone from the van and the invoice goes out the same day, not the following Sunday, the way voice notes turn into invoices without you opening a laptop. The slow payers get chased in your own voice on a schedule instead of whenever you remember and feel brave enough. You set the rate. Vanly makes sure you collect it. A rate you calculated and then failed to invoice is just a number on a quote.
FAQ
What is the average plumber hourly rate in the UK in 2026?
The national average for standard domestic work in 2026 is roughly £45 to £75 per hour, lower at £35 to £60 across the North and Wales, and £65 to £105 in London and the South East. Emergency and out of hours work runs £80 to £150 per hour. Those are the prices customers pay. They are a market reference, not the rate you should set your own pricing by, because they do not account for your costs or your unbilled hours.
What should a newly self employed plumber charge per hour?
Work it backwards rather than copying the going rate. Take your target take home, gross it up for tax and National Insurance, add your annual overheads, then divide by the hours you will realistically bill, which for a solo domestic plumber is closer to 1,200 than 2,080. For most that lands the floor around £50 an hour, not the £40 a mate might quote. Charging below your calculated floor means working at a loss.
Is a day rate better than an hourly rate for plumbing work?
It depends on the work. A day rate is simpler for predictable full days, bathroom installs, boiler swaps, and subbing for a contractor, and customers find it easier to understand. An hourly rate with a minimum first hour suits small unknown jobs and leak finding. Whichever you use, check that it still clears your calculated hourly number once you divide by the hours you are genuinely productive, not the hours you are away from home.
How many billable hours does a self employed plumber really work in a year?
Far fewer than the 2,080 in a full time year. Once you take out holiday, illness, quoting, driving, merchant runs, training, scheme assessments, and admin, a solo domestic plumber typically bills between 1,000 and 1,300 hours. Pricing as if you will bill 2,080 is the single most common reason new plumbers end up underpaid.
Should I charge a call out fee or a minimum first hour?
Yes, for small jobs. A call out charge or a minimum first hour of £60 to £120 covers the drive and the booking slot you can no longer sell to anyone else. Customers who balk at it are usually the ones who would have taken two hours of free advice and booked someone else anyway. It is normal practice across the trade, not a hard sell. Emergency and out of hours work sits higher again, typically £80 to £150 per hour on top of the call out.
Will charging more than the going rate lose me work?
Some, and usually the work you want least. Price shoppers chasing the cheapest quote rarely become good long term customers and often turn into the late payers you spend Sundays chasing. Price at a rate that pays you, be quick, tidy, and reliable, and you win the customers who pay on time and call you back. A diary full of underpriced jobs is a slow way to go out of business while looking busy.
The bottom line
The honest answer to how much a plumber should charge per hour in the UK is that there is no single number, and the cost guides ranking for it are answering the customer's question, not yours. Your number comes from your target take home, your real overheads, and the hours you will actually bill, and for most solo domestic plumbers it sits higher than the going rate the public sees. Work it out once, properly, and stop guessing.
Then make sure you collect every hour of it. The rate is only half the job. Getting the invoice out the day you finish, and chasing the ones who drag, is the other half, and it is the half that quietly decides what you really earned this year. Try Vanly free for 14 days. No card needed to start.
