Some things genuinely cannot wait until morning. Others can, and knowing which is which saves you an after-hours call-out you did not need. Here is the honest version of both.

These get worse by the hour, and in two of them the cost of waiting is not plumbing, it is everything the water touches.
A burst pipe, a split flexi hose under a vanity, a cylinder that has let go. If the water is running and you cannot shut it off at the fixture, the clock is on. Turn it off at the meter at the front boundary, clockwise, then ring.
This is the one not to weigh up. Turn the gas off at the meter if you can reach it safely, open the doors and windows, do not touch light switches or anything that sparks, and get out if the smell is strong. Then call from outside.
An overflowing floor waste or a toilet backing up into the shower means the line is blocked downstream of the house. It is a health problem as much as a plumbing one, and it does not resolve on its own.
A leak above a ceiling, running down a wall, or anywhere near a switchboard or downlights. Water and electricity in the same space is the one combination worth paying after-hours rates to end.
None of these are fun. All of them cost less in daylight, and an honest plumber will tell you so rather than take the call-out.
Uncomfortable, not urgent. If the unit is leaking badly that changes it, but a cold shower on a Tuesday night is a morning job and you will pay less for it. More on how long a system lasts and the signs yours is going.
Annoying and it does waste water, but nothing is being damaged tonight. Pop a bucket under it and book it in with whatever else needs doing.
A single sink or shower draining slowly is a build-up, not a blockage. It becomes urgent when more than one fixture goes at once, because that points at the main line rather than the fixture. If it is a proper blockage, what it costs to clear a drain covers what moves the price.
The cistern refilling constantly is a worn valve. It will show up on your next water bill rather than on your floor, so it can wait for a normal visit.
These are the calls where the answer is genuinely "it depends", and the detail that decides it is usually simple.
If a bucket and a towel are holding it, it can wait. If the bucket fills in under an hour, or the water is going somewhere you cannot see, it cannot.
One toilet in a two-toilet house is a morning job. The only toilet in the house, with people in it, is reasonably an emergency, and most plumbers will treat it that way.
Usually a water main issue rather than yours, and worth checking whether the neighbours have it too before anyone comes out. If it is just you and it came on suddenly, that is worth a look.
Most of the damage in a plumbing emergency happens before anyone arrives. These are all things you can do yourself while you wait.
The main tap is usually at the front boundary and turns clockwise to shut off. Worth finding it on a calm afternoon rather than at eleven at night in the rain.
Most toilets, sinks and hot water units have their own small isolating tap. Turning that off stops the problem without shutting down the whole house.
Rugs, boxes, anything on the floor in the path of it. Water damage to belongings is usually the expensive part, and it is the part you can prevent in two minutes.
Before you mop up. If an insurance claim follows, the photo taken at the time is worth more than any description afterwards.
Generally yes, and that is true of every trade. It is why this page exists. If the thing can genuinely wait until morning you will pay less for it, and we would rather tell you that than take the call-out.
If you have turned everything off and the meter is still ticking over, water is going somewhere, and somewhere you cannot see is the worst place for it to go. That is worth a call rather than a wait.
Yes, because a drain that clears itself has not been fixed, it has shifted. The usual cause is roots or a cracked section, and both come back. A camera down the line tells you which you are dealing with.
You get a price before any work starts, so you are never agreeing to something open-ended. Ring and describe what is happening and we will tell you honestly whether it needs tonight or morning.
Ring anyway and describe it. Working out whether something can wait is a thirty second conversation, and you will not be talked into a call-out you do not need.
