24/7 Emergency Response
Emergency Plumber London
Most of what gets phoned through overnight is not an emergency, and we will tell you so even though saying it costs us the call-out. An emergency is water that is moving and doing damage right now. A dripping tap, a cold radiator, a toilet that keeps running: those are jobs, and a booked daytime slot does them better and for less.
How an emergency attendance is priced
| Job | How it is charged | Time |
|---|---|---|
| Getting an engineer to the door and the water stopped | Attendance rate for that time band, quoted on the call | The first thing that happens |
| Weekday daytime attendance | Standard band, the cheapest way to buy the same work | Office hours |
| Evening, night, weekend or bank holiday attendance | Uplifted band, named before anyone travels | Always staffed |
| Work carried on past the first hour | Told to you as it happens, never discovered on the invoice | Only if the job needs it |
| Anything that can safely wait for daylight | Booked at the daytime band instead | Next working day |
How each stage is charged, not a quote. The detection fee is fixed and agreed on the call, before an engineer travels.
What makes the difference to the bill is almost never the part that failed. It is how long water kept moving before somebody shut the supply. That is why the first thing you will be asked is what the water is doing and whether you can get to your stop tap, and why nobody will ask for card details before answering that.
When it genuinely is urgent, we are staffed for it at any hour of any day. An engineer is assigned from whoever is nearest and actually free, and you will be told plainly what is realistic. What you will not get is a promise of twenty minutes, because nobody crossing London at any hour can honestly make one.
The rate depends on the hour on the clock and nothing else. The same job at the same time costs the same however alarmed the phone call was. The applicable band is stated before anyone travels, never discovered on your doorstep, and charging starts when the engineer arrives rather than when the van leaves, because London traffic is our problem to manage and not a line on your invoice.

How it works
A method, not a guess
01
Three questions
What is the water doing, can you reach the stop tap, and is anything electrical involved. Those answers decide whether this needs a van tonight or a slot tomorrow.
02
Stopping it from where you are
We stay on the line while you find the isolation point. In most London homes it is under the kitchen sink, in a hall cupboard, behind a bath panel or out on the shared riser.
03
Assigning, and being straight about it
You are told which engineer is coming, roughly where they are and what is realistic. If something changes on the way, you get a call rather than silence.
04
Contain, then repair
Water stopped first, cause established second, repair third. Where the fault is reachable and the parts are standard, it is finished on the visit rather than rebooked.
Sorting a genuine emergency from a job that can wait
Apply the moving water test
An emergency is water that is moving and doing damage right now. That is the whole definition and it is more useful than any list. A burst pipe, water coming through a ceiling, anything running near electrics, or a leak you cannot isolate all qualify. A dripping tap, a radiator that will not heat, a slow weep into a bucket and a toilet that keeps filling do not, however annoying they are at midnight. Getting this right is worth real money, because the second category costs noticeably less booked into daylight.
The clock sometimes starts before the van does
Some firms begin charging from the moment the engineer sets off rather than from the moment they arrive, which converts London traffic into billable labour and makes distance your problem rather than theirs. It is rarely volunteered and almost always answered honestly if you ask. Put the question plainly when you ring: does the charge start on departure or on arrival. The answer tells you something about the firm beyond that one detail.
Two firms can both say tonight and mean different things
One means an engineer who will stop the water, work out the cause and repair it if the pipe is reachable. The other means somebody who will look, cap it off and book the actual work as a second chargeable visit. Both descriptions are honest and only one solves your problem this evening. Ask directly whether the engineer arrives with pipe, fittings and the tools to cut and joint, and whether an accessible repair can be completed on the visit.
Know the published rates well enough to spot an outlier
You cannot negotiate properly in the middle of the night without some reference point. Checkatrade publishes a UK average of £162 for leak detection, with most jobs between £115 and £234 and a full recorded spread of £80 to £1,600, with hourly diagnostic rates published at £95 to £145 and emergency call-out charges at £100 to £120. Those are third-party figures for the market rather than a quote for your job, and every property is different. They are still enough to tell you when a number you are hearing at 1am sits well outside what the trade generally charges.
Find out who is actually turning up
There is a substantial layer of businesses that take the booking and pass it to whoever accepts it, which means the firm you researched and the engineer at your door can be unconnected. It is not automatically bad work, but it does mean nobody has continuity of responsibility if something goes wrong later. Ask whether the attending engineer is employed by the company you rang. A firm that dispatches its own people will say so without hesitating.
Do the things that cost nothing while you wait
Shut the stop tap. Move what can be moved out of the way. Put something under the drip. Turn off power to any circuit where water is near a fitting, at the consumer unit rather than at the switch. Photograph everything before you tidy, because the record is easy now and impossible later. None of this needs a tradesperson and all of it reduces what the incident eventually costs you.

What actually makes a call-out an emergency
Most calls that come in overnight are not emergencies, and saying so costs us work. An emergency is water that is moving and doing damage right now. A tap that drips, a radiator that will not heat, a toilet that runs: those are jobs, and booking them for daylight is cheaper for you and better done. The difference matters, because the out-of-hours band exists for the first category and gets applied to the second.
| What to check | A firm that treats every call as urgent | A bookings platform | How we run the call |
|---|---|---|---|
| Triage on the phone | None. Every call is an emergency because every emergency carries the higher rate. | An automated form that cannot tell a burst pipe from a dripping washer. | Three questions about what the water is doing. They decide whether you need a van tonight or a slot tomorrow. |
| Being told to wait | Never, since a deferred job is a lost job. | Not offered, because the platform earns on the booking either way. | If the supply is isolated and nothing is spreading, we will say it can wait and quote you the cheaper daytime band. |
| Who turns up | Whichever subcontractor accepted the job, unknown to the firm that sold it to you. | A name from a list, matched on availability rather than on the problem. | One of our own engineers, chosen for what you described and where they currently are. |
| When the charging starts | The moment the van leaves, so London traffic is billed to you as labour. | Set by the contractor, and often not disclosed until afterwards. | On arrival. Travel is our problem to manage, not a line on your invoice. |
| Stopping the water | Begins when the engineer arrives, whenever that turns out to be. | Left entirely to the attending trade. | Begins on the phone. We would rather you stopped it in two minutes than we stopped it in forty. |
| Finishing it tonight | A make-safe and a second appointment, charged twice. | Depends entirely which contractor accepted the job. | Where the fault is reachable and the parts are standard, it gets finished. Where it is not, we say so before you commit. |
| What the rate depends on | How worried you sounded, and how late it is. | The platform's margin on top of the trade's own rate. | The hour on the clock and nothing else. The same job at the same time costs the same however panicked the call was. |
From the forums
The questions that come up when a leak starts
The emergency plumbing discussions on public discussion are unusually consistent, and the strongest recurring advice has nothing to do with choosing a firm. It is about the ten minutes before anybody arrives, and what people wish they had known about their own property.
The standing advice to locate your stopcock before you need it
This is the most repeated piece of guidance on the subject and it comes from people who learned it the hard way. Posters describe losing valuable minutes searching cupboards while water came through a ceiling, or finding the valve and discovering it was seized solid. Regulars advise testing it periodically and telling everyone in the household where it is. The difference between the people who post about a contained incident and the people who post about a ruined floor is very often this one thing.
Complaints about charging that began when the van left
A recurring invoice dispute involves travel time appearing as labour, sometimes substantially, on jobs where the engineer came across London. The general view is that this is legitimate if disclosed and objectionable if it appears afterwards. The advice that follows is always the same: ask before they set off whether the clock starts on departure or on arrival, and get the answer in writing if the job is likely to be a long one.
Threads about call-outs that turned into two visits
People describe paying an out-of-hours attendance for someone who assessed the problem, made it temporarily safe and booked a second appointment to do the work, then paid again. Sometimes that is unavoidable because of what the pipe is buried in. Often it was because the van did not carry what was needed. The lesson people draw is to ask what the engineer is bringing, since the answer changes what the call-out is worth.
Discussion of what counts as an emergency in the first place
There is a healthy strain of public discussion advice telling people to calm down and wait until morning, usually from tradespeople. The reasoning is consistent: if the water is off and nothing is deteriorating, an out-of-hours rate is buying urgency that has already been achieved for free. Posters who took that advice generally report being glad they did. It is also a reasonable test of the firm you rang, since the honest ones say it first.
Warnings about agreeing to anything on the doorstep
A cluster of unhappy posts share a shape: no figure given on the phone, a price produced once the engineer was inside, and a customer in no state to argue at two in the morning. The advice is to settle the attendance rate before anyone travels and to be suspicious of any firm that will not do so. Wet, tired and cornered is the worst possible position to be negotiating from, and some operators know it.
Symptoms
Jobs that need an emergency plumber tonight
Not every leak is a full detection survey. These problems need a plumber on site fast.
- No water / cannot isolate a stuck stopcock
- Overflowing toilet, failed ball valve or burst flexible hose
- Severe leak under kitchen or bathroom with flooding
- Boiler leaking onto electrics or floor
- Blocked soil stack threatening sewage backup
What helps an emergency call-out
- 1Describe the postcode, property type and whether water is still flowing.
- 2Try the stopcock: lefty-loosey, often under the kitchen sink.
- 3Keep phones charged and provide access instructions for the engineer.
- 4Ask for the call-out fee and first-hour rate before we travel.
Emergency plumbing + leak detection
If the source is obvious we repair it. If water is coming from a void, ceiling or underfloor with no clear origin, we switch into multi-method leak detection so the permanent fix is in the right place.

Built for how London actually leaks
Housing stock across the capital fails in different ways. We match the method to the building, not a one-size survey script.
Victorian & Edwardian terraces
Original floorboards, cast-iron stacks and decades of patch repairs. We pressure-test circuits and listen through timber before any board is lifted.
Mansion blocks & conversions
Shared risers, stacked bathrooms and flat-to-flat disputes. Origin reports settle liability between leaseholders, freeholders and block insurers.
Post-war & 1970s stock
Copper branches, cold-water tanks and ageing joints. Acoustic and thermal methods locate slow drips that never show as a flood.
New-build flats & towers
Plastic pipe, underfloor heating and boosted mains. Tracer gas and thermal imaging matter more than a listening stick alone.
Questions
Emergency Plumber FAQs for London homeowners
How do I know whether this is actually an emergency?
Ask whether water is still moving and whether it is reaching anything that matters. A burst pipe, water coming through a ceiling, or a leak anywhere near electrics all qualify. A drip into a bucket, a radiator that will not warm up, or a slow weep under a sink do not, and putting them in the daytime band costs you noticeably less for exactly the same work.
Why won't you tell me you will be there in twenty minutes?
Because it would not be true, and a figure invented to win a booking is worth nothing once you are relying on it. What we will tell you is where the nearest available engineer actually is and what that realistically means, and we will call you if it changes. An honest window you can plan around beats an optimistic one that quietly slips.
I cannot find my stop tap. What now?
Stay on the phone and we will work through the usual spots: under the kitchen sink, in a downstairs cupboard, behind the bath panel, under the stairs, or in the communal riser just outside a flat door. If yours is seized, which is common in older London stock, there may be a local isolation valve on the run instead. Worth locating and testing before you ever need it.
Will the job be finished in one visit?
Where the pipe can be reached and the fittings are standard, yes. Engineers carry pipe, fittings and the tools to cut and joint, so an accessible fault is repaired rather than capped and rebooked. Where it sits under screed or behind tiling, we make it safe and are straight with you about what still needs doing and when it is best done.
Do you charge more at night and on bank holidays?
Yes, and the band is said out loud before anyone sets off. Out-of-hours work costs more to staff, so pretending otherwise would just mean finding it somewhere else on the invoice. It also means that if your situation is stable, moving to a daytime slot is a real saving, and we will point that out when it applies.
What actually counts as a plumbing emergency?
Water that is moving and causing damage now. Burst pipes, water coming through ceilings, anything leaking near electrical fittings, a leak you cannot isolate, or a total loss of water supply to the property. Slow drips, cold radiators and running toilets are jobs rather than emergencies. Booking those into a daytime slot costs meaningfully less for identical work, and we would rather tell you that than take the out-of-hours booking.
How quickly will someone get to me?
We will not give you a headline figure, because nobody crossing London at any hour can honestly promise one and a number invented to win a booking is worthless when you are relying on it. What you will be told is where the nearest available engineer actually is and what that realistically means, and you will get a call if it changes. Meanwhile the phone advice starts immediately, which is usually what stops the damage.
What should I do before the engineer arrives?
Shut the stop tap. Move valuables and furniture clear. Contain drips with whatever is to hand. If water is anywhere near electrical fittings, isolate that circuit at the consumer unit rather than touching the switch. Photograph the scene before you start clearing up, because it is the only chance you will get. Then leave surfaces alone and do not start opening anything up.
Do you charge extra at night, at weekends and on bank holidays?
Yes, and the band is stated before anyone travels rather than discovered afterwards. Staffing the small hours costs more, and a firm claiming otherwise is recovering it somewhere less visible. The practical consequence is that if your situation is stable, moving to a daytime slot is a genuine saving, and we will tell you when that applies to you.
Will the repair be finished in one visit?
Where the pipe is reachable and the fittings are standard, yes. Engineers carry pipe, fittings and the tools to cut and joint so an accessible fault is repaired rather than capped and rebooked. Where it sits under screed, behind tiling or inside a wall, we make it safe and tell you plainly what remains, what it involves and when it is best done.
Can you help if the leak is coming from the flat above?
We can attend and establish where the water is entering your property, which is often the thing in dispute. Working on pipework in someone else's flat needs their agreement, so it helps enormously if the neighbour or the managing agent is contactable. Getting the source properly identified is what usually ends the argument about who arranges the repair.
