How Much Does a Plumber Cost Per Hour in London? (2026)

Last updated: July 2026

TL;DR: A plumber in London typically charges £40 to £60 an hour for scheduled weekday work in 2026, or around £350 a day. Most jobs are quoted as a fixed price rather than by the hour. Always ask whether VAT is included, and compare at least three written quotes.

A plumber in London typically charges £40 to £60 an hour for scheduled weekday domestic work in 2026, with a day rate of around £350 [2]. That is the labour figure. Most plumbing work you will actually book is not sold by the hour at all: it is quoted as a fixed price for a defined job, built from the expected time plus parts.

This guide sets out the current London hourly and day rates, what common plumbing jobs cost, what a fair quote should itemise, why London runs above the rest of the country, and the work that legally requires a Gas Safe registered engineer rather than a general plumber.

One thing worth saying plainly at the outset. The most authoritative consumer source in this market, Which?, deliberately does not publish a single headline hourly rate for plumbers. It prices each job individually instead [1]. That is a useful signal about how this trade actually works, and it is why the job table further down this page is more useful than the hourly figure at the top of it.

Plumber rates in London at a glance (2026)

Measure	London (2026)	Notes
Hourly rate, scheduled weekday work	£40 to £60	Federation of Master Builders labour data, February 2026 [2]
Day rate	Around £350	Same source; describes project labour on a multi-day job [2]
Half day	Not independently published	Commonly around half the day rate plus a minimum charge. Ask directly
Minimum charge	Applies almost everywhere	Usually one hour, however quick the task. Confirm the figure when you book
Emergency and out-of-hours	Priced separately, materially higher	See our emergency plumber cost guide

Treat every figure as a planning guide, not a quote. The final price depends on the job, the postcode, the age of the pipework and the individual plumber. Get more than one written quote, and check whether VAT is included before you compare two numbers against each other.

A note on higher figures. You will see London plumbing quoted at £100 an hour or more in places, including on some cost-comparison pages. Those numbers almost always describe emergency, evening, weekend or short-notice work, where the plumber is being pulled off another job or out of their own time. They are not the rate for a visit you booked last Tuesday for this Thursday morning. Rates above roughly £85 an hour for scheduled daytime work in London are the exception rather than the norm, and are most often seen from VAT-registered firms, central London operators, or specialists. If a scheduled-work quote is well above the band in the table, ask what is driving it. There may be a good answer, and you are entitled to hear it.

What a fair plumbing quote should include

This is the most useful thing to have in front of you when you compare quotes. Run through it before you agree to any booking:

• Hourly or fixed price? Small repairs and diagnostics are often billed hourly. Anything with a defined scope, from fitting a basin to swapping a radiator, should come as a fixed written quote. Ask which you are being given, because the two are not the same promise.
• The minimum charge, and how time is billed after it. Ask the minimum, and whether time beyond it is billed by the hour or the half hour. This is the single biggest source of surprise on a small job.
• VAT. A plumber whose taxable turnover is below the £90,000 registration threshold is not required to charge VAT, while an established firm above it adds 20 per cent [3]. Which? states that its published prices exclude VAT [1], and many quotes do not say either way. Two quotes are not comparable until you know.
• Parts, materials and markup. Are taps, valves, pipe and fittings in the price or charged on top, and at what markup? If you supply the parts yourself, confirm the plumber will fit customer-supplied goods, and what happens to the guarantee if one fails.
• Travel and parking. Most London plumbers pass on parking, and some pass on the Congestion Charge or ULEZ. Ask whether these are included or will land on the final invoice.
• What is excluded. A quote for a tap swap does not usually include replacing seized isolation valves found on the day. Ask what would change the price, and by roughly how much.
• Making good. If pipework is chased into a wall or floorboards are lifted, establish who puts it back and whether that is priced in.
• Deposit and payment terms. Which? advises paying no more than 25 per cent upfront, with the balance on completion [1].
• Guarantee. Ask what workmanship guarantee is offered, for how long, and get it in writing.
• Gas Safe registration, if any gas is involved. Non-negotiable, and covered in full below.

Get all of it in writing, even in a short email or text. A quote is a promise to do work at an agreed price, and Citizens Advice is clear that a trader cannot charge more than a quoted price unless you agreed to extra work, or the pricing mistake was obvious to most people [14].

How London compares with the rest of the UK

London and the South East sit at the top of the national range. Which? puts it directly, noting that prices "are likely to be at the upper end of the scale if you live in London or the South East" [1]. The Federation of Master Builders makes the same point about labour specifically, observing that outside the capital labour prices are generally lower [2].

We are not going to attach a percentage to that gap, because no reliable dated source publishes a clean UK average hourly rate for plumbers alongside a London figure. Anyone quoting you a precise London premium is almost certainly deriving it from two sources that were never designed to be compared. The honest statement is the directional one: London is consistently the most expensive part of the country for plumbing labour, and the reasons for it are concrete rather than mysterious.

Hourly rate, day rate or fixed price?

Which one you should ask for depends entirely on the job.

Ask for a fixed price when the scope is knowable in advance: fitting a new toilet, replacing a basin, installing an outside tap, swapping a radiator for the same size. You are buying a defined outcome, and the plumber carries the risk of it taking longer than expected. This is the right structure for most bookings.

Accept an hourly rate for diagnostic and investigative work: tracing an intermittent leak, finding out why the pressure has dropped, clearing a blockage of unknown cause. Nobody can quote a fixed price to find something they have not found yet, and a plumber who offers one has usually padded it heavily.

Use the day rate as a sense check. At around £350 a day, a job quoted at £1,000 in labour should be taking roughly three days. If the quote says one day, that is not necessarily wrong, but it is a fair question to ask.

A low headline hourly rate can easily cost more than a higher one. A plumber charging £45 an hour who takes four hours is more expensive than one charging £60 who takes two. Rate is not price.

What common plumbing jobs cost in London (2026)

The figures below come from Which?'s survey of 25 Which? Trusted Traders, conducted in November 2025 and published on 1 May 2026. All exclude VAT [1]. These are UK-wide survey ranges, and Which? notes London sits at the upper end, so treat the top of each range as the more realistic London figure.

Job	Cost range (excluding VAT)	Typical time	Usually priced as
Fix a leaky kitchen tap	£45 to £200	About 1 hour	Hourly or minimum charge
Replace a kitchen mixer tap (isolation valves present)	£50 to £200	1 to 2 hours	Fixed price
Replace a kitchen mixer tap (no isolation valves)	£90 to £300	About 2.5 hours	Fixed price
Replace a faulty ball valve in a cistern	£50 to £300	1 to 2 hours	Hourly or minimum charge
Install an outside tap	£80 to £400	About 2 hours	Fixed price
Fix or unblock a toilet	£80 to £300	1 to 2 hours	Call-out plus hourly
Fit a new toilet	£80 to £600	2 to 4 hours	Fixed price
Fit a new pedestal basin	£80 to £800	2 to 4 hours	Fixed price
Fix a burst water pipe	£100 to £500	1 to 2 hours	Call-out plus hourly
Replace a cold water tank	£200 to £900 (tank not included)	Half to one day	Fixed price
Replace a hot water tank	£350 to £1,000 (tank not included)	Half to one day	Fixed price

Two honest gaps are worth naming. There is no comparably reliable published figure for radiator replacement, stopcock replacement, or clearing a blocked waste pipe as distinct from a blocked toilet. In practice these are usually charged at the standard hourly rate for one to three hours depending on access, but we are not going to invent a range for them. Ask for a fixed quote after the plumber has seen the job.

For the two jobs this site covers in depth, see what it costs to replace a bathroom tap in London and, at the other end of the scale, a full bathroom renovation budget. If the job in question is a boiler rather than pipework, what a new boiler costs in London breaks that down separately.

What pushes a London plumber's rate up or down

Where the property is, and what it costs to reach it. The Congestion Charge rose to £18 a day on 2 January 2026, its first increase since 2020, and rises to £21 if paid by midnight on the third day after travel [4]. ULEZ adds £12.50 a day for a non-compliant van, and operates 24 hours a day across every London borough [5]. A plumber running a non-compliant vehicle into central London can face over £30 a day in charges before turning a single tap. That cost does not exist in Manchester or Leeds, and it is a legitimate, documented part of the London premium.

The age of the pipework. London's housing stock is unusually old. More than a quarter of London homes were built before 1919, and around 23 per cent date from before 1900, ranging from 1 per cent in Barking and Dagenham to 65 per cent in Kensington and Chelsea [6]. Period properties bring original lead or galvanised steel pipework, non-standard fittings and imperial pipe sizes, all of which turn a straightforward job into a slower one. A tap swap in a 2015 flat and the same swap in a Victorian terrace are not the same job.

Access. Boxed-in pipework, a basin fitted tight into a corner, a stopcock behind a fitted kitchen unit, or a top-floor flat with no parking all add time. Access is the single most common reason a quote comes in above the range you expected.

Isolation valves, or the absence of them. This is the clearest example in the Which? data: the same kitchen tap swap costs £50 to £200 with working isolation valves and £90 to £300 without, because the plumber has to drain down the system first [1].

VAT registration status. The same work from a VAT-registered firm costs 20 per cent more than from a sole trader below the £90,000 threshold [3]. Neither is cutting corners. They are different businesses at different scales, and the difference has nothing to do with quality.

When you legally need a Gas Safe registered engineer

This is the part of the article where the price stops being the point.

By law, anyone carrying out gas work in the UK must be on the Gas Safe Register [8]. The requirement sits under the Gas Safety (Installation and Use) Regulations 1998, enforced by the Health and Safety Executive, which states that a gas business must be on the Gas Safe Register to legally undertake gas work within the scope of the regulations [7]. It is a criminal offence for an unregistered person to work on a gas appliance, and it is equally an offence for a registered engineer to sign off work carried out by someone who is not [8].

The boundary matters because "plumber" and "gas engineer" are not the same qualification:

• A general plumber may legally handle taps, sanitaryware, water pipework, tanks, radiators, leaks and blockages, with no Gas Safe registration required.
• Gas work requires Gas Safe registration. That means fitting, servicing, repairing or disconnecting a boiler, any gas appliance, gas pipework or a gas fitting, regardless of how experienced the plumber is at everything else.
• One narrow exception. Gas Safe Register's own guidance allows another competent tradesperson to replace a genuinely non-gas component, such as a circulating pump or a heating control valve housed inside a boiler's casing, provided the work does not break a combustion chamber seal, disturb any gas-carrying component, or disturb a module controlling combustion [10]. If there is any doubt at all, it is a gas engineer's job.

How to check, in about a minute. Search the register at gassaferegister.co.uk by licence number or postcode, or call 0800 408 5500 [8]. Then ask to see the ID card. The front carries the engineer's photo, name, a unique licence number embossed across the card, a hologram, and an expiry date. Registration is renewed every 12 months, so an expired card means the person should not be doing the work. The back lists the specific categories of gas work they are registered for, such as boilers, cookers or fires. Registration for one category does not qualify someone for all of them [9].

Do not treat this as box-ticking. Gas Safe Register research published in 2018 found that two thirds of illegal gas work inspected was unsafe, with roughly one in five inspected jobs dangerous enough that the appliance had to be turned off immediately to prevent explosion, fire or carbon monoxide poisoning [11]. Using an unregistered person can also invalidate a boiler's manufacturer warranty and may invalidate home insurance [10].

Which plumbing work needs building regulations approval

Some plumbing work is notifiable, meaning it must either be reported to a building control body or be self-certified by an installer registered with a competent person scheme. Gov.uk lists new bathroom installations involving new or materially altered plumbing, and new or replacement boilers and heating systems of any fuel type, as examples of notifiable work [12].

Where the installer belongs to a relevant competent person scheme, such as APHC, NAPIT or BESCA, they can self-certify compliance without a separate building control application, and you should receive a compliance certificate within 30 days of completion [13]. Ask for it, and keep it. It is the paperwork a buyer's solicitor will want years later.

If the job also involves new electrical work in a bathroom or kitchen, for example a shaver socket or an extractor fan, that is separately notifiable under Part P of the Building Regulations and needs a registered electrician. Our guide to what an electrician charges per hour in London covers where that boundary sits.

Your rights, and how to get a fair quote

Under the Consumer Rights Act 2015, a service must be carried out with reasonable care and skill. If no price was agreed in advance, the price charged must be reasonable, and if no timescale was agreed, the work must be completed within a reasonable time [15]. Where work falls short, you can ask the trader to put it right, and where that is not practical you can seek a price reduction [14].

TrustMark, the Government Endorsed Quality Scheme, advises getting at least three quotes for any planned work, checking qualifications and insurance, taking up references from previous customers, and agreeing scope, timeline and price in writing before anything starts [16]. Which? adds the practical version: ask plumbers to break down their quotes so you can see what you are being charged for [1].

In practice, the most effective thing you can do costs nothing. Write one list of every plumbing job you want doing, send the same list to three plumbers, and ask each for a written quote against it. Batching also saves real money, because a plumber already in your home can often handle three small jobs inside the time a single minimum charge would have covered anyway.

Finding a trusted plumber in London

The cheapest hourly rate is rarely the cheapest job, and for anything touching gas the registration check matters more than the price. Ask for the quote in writing, ask what is excluded, and check the Gas Safe Register yourself rather than taking a logo on a van at face value.

Frequently asked questions

How much does a plumber charge per hour in London? A plumber in London typically charges £40 to £60 an hour for scheduled weekday domestic work in 2026, with a day rate of around £350 [2]. Most plumbers apply a minimum charge of about one hour however quick the job. Emergency and out-of-hours work is priced separately and costs considerably more.

Do plumbers charge a call-out fee? For scheduled work, most London plumbers do not charge simply to quote, but nearly all apply a minimum charge once they attend, commonly the first hour billed in full. Emergency call-outs work differently and carry their own higher fee. Always ask for the exact minimum in writing before anyone travels to you.

Do plumbers charge VAT on labour? It depends on the plumber. A business must register for VAT once its taxable turnover passes £90,000 in a rolling 12 months [3]. A sole trader below that threshold does not charge VAT, so their quote can be up to 20 per cent lower than a VAT-registered firm's for identical work. Always ask before comparing quotes.

Is it cheaper to pay a plumber hourly or a fixed price? Ask for a fixed price whenever the job has a knowable scope, such as fitting a toilet or a basin, because the plumber then carries the risk of it overrunning. Accept an hourly rate only for diagnostic work, such as tracing a leak, where nobody can reasonably quote before finding the fault.

Why are London plumbers more expensive than the rest of the UK? Which? confirms prices sit at the upper end of the scale in London and the South East [1]. Three concrete reasons drive it: the £18 daily Congestion Charge and £12.50 ULEZ charge [4][5], slow cross-city travel between jobs, and housing stock where over a quarter of homes predate 1919 and bring older, slower pipework [6].

Does a plumber have to be Gas Safe registered? Only for gas work, and then it is a legal requirement, not a preference [7][8]. A plumber needs no gas registration to fit taps, basins, radiators or water pipework. Anything touching a boiler, a gas appliance or gas pipework requires a Gas Safe registered engineer. Check the register and the ID card before work starts.

How many quotes should I get for plumbing work? TrustMark advises getting at least three quotes, plus checking qualifications and insurance and taking up references from previous customers [16]. Send all three plumbers the same written list of jobs so the quotes are genuinely comparable, and agree scope, price and timescale in writing before any work begins.
