No Water From Taps? Here's What to Check First

By The FixDelivered Team · Updated 2026-07-04 · 7 min read

Waking up to find no water coming from your taps can be a frustrating and worrying experience. Whether it's just one tap, all your cold taps, or your entire home is without water, it's a problem that needs addressing quickly. Before panicking or calling an emergency plumber, there are several checks you can carry out yourself to identify the cause and potentially resolve the issue. This guide will walk you through the most common reasons you might have no water and what steps to take.

Why is There No Water from My Taps? Common Causes

Understanding the potential culprits behind your water outage can help you troubleshoot more effectively:

External Supply Issues: The most common reason for no water is often beyond your property line. This could be planned maintenance by your water supplier or an unexpected burst main in your area.
Frozen Pipes: During colder months, water inside your pipes can freeze, blocking the flow. This is particularly common in exposed pipes in attics, garages, or outside walls.
Main Stopcock or Isolation Valve Closed: Your main stopcock (or stop tap) controls the water supply to your entire property. If it's accidentally turned off or only partially open, you'll experience reduced or no water. Individual isolation valves on appliances (like under a sink) can also be an issue for specific taps.
Boiler or Water Heater Problem (Hot Water Only): If you have cold water but no hot water, the issue almost certainly lies with your boiler or hot water cylinder. This could be due to a lack of power, a fault, or low pressure.
Air Lock in Pipes: Less common but possible, an airlock occurs when a bubble of air gets trapped in your pipework, preventing water from flowing. This usually affects a single tap.
Burst Pipe on Your Property: A more serious issue, a burst pipe can lead to a sudden loss of water pressure or complete outage, often accompanied by visible damp patches or the sound of running water where it shouldn't be.
Low Water Pressure: While not strictly 'no water', extremely low water pressure can sometimes feel like an absence of flow, especially in upstairs taps.

What to Check First: A Step-by-Step Guide

Before calling for professional help, work through these steps to diagnose the problem:

Step 1: Check with Neighbours and Your Water Supplier

This is always your first port of call. If your neighbours also have no water, the problem is likely with the main supply to your area, meaning it's out of your hands and your water company is responsible.

Ask Your Neighbours: Pop next door or check local community groups to see if others are affected.
Check Your Water Supplier's Website: UK water companies typically have a 'live updates' or 'in your area' section on their websites where they post information about planned maintenance and unexpected outages.
Social Media: Many water suppliers use platforms like X (formerly Twitter) to provide real-time updates.
Contact Your Supplier: If you can't find information online and your neighbours are also affected, call your water company directly. They can confirm if there's an issue in your postcode.

If the problem is with the main supply, you'll usually just need to wait for your water company to resolve it. They will often provide estimated restoration times.

Step 2: Locate and Check Your Main Stopcock

Your main stopcock controls the water supply to your entire property. It’s crucial to know where it is.

Find It: The internal stopcock is usually under your kitchen sink, in a downstairs toilet, or near the water meter (if you have one). The external stopcock is typically found in a small cover on your property boundary, often near the pavement.
Ensure it's Fully Open: Turn the stopcock handle anti-clockwise until it stops. Sometimes, a partially closed stopcock can drastically reduce water flow. Do not force it if it feels stiff.
Check Individual Isolation Valves: Many modern taps and appliances have small isolation valves on the pipework leading to them. Check these are fully open, especially if only one tap has no water.

Step 3: Check for Frozen Pipes

If it's winter and temperatures have been below freezing, frozen pipes are a strong possibility, especially if you have no water from taps in exposed areas like an unheated extension or loft.

Identify Affected Areas: Open all your taps slightly. If water comes out of some but not others, or if only the cold tap is affected in a specific location, it points to a localised freeze.
Look for Visible Signs: Check any visible pipework for frost, ice, or bulging (a sign of ice expansion).
Gentle Thawing: If you suspect a frozen pipe, you can try to thaw it gently.

Open the affected tap slightly.
Apply gentle heat to the suspected frozen section of pipe using a hairdryer on a low setting, hot water bottles, or towels soaked in hot water.

Safety Caution: NEVER use a blowtorch, boiling water directly on pipes, or any other open flame or intense heat source, as this can cause pipes to burst or damage fittings, creating a much bigger problem.

If you suspect a frozen pipe has burst (e.g., you see water leaking as it thaws), immediately turn off your main stopcock and call a professional plumber.

Step 4: Is it Only Hot Water? Check Your Boiler or Water Heater

If you have cold water but absolutely no hot water from any tap, the issue is with your hot water system.

Boiler Check:

Power: Is your boiler switched on and getting power? Check the fuse spur.
Display: Are there any fault codes or error messages on the boiler's display? Consult your boiler manual.
Pressure: Check the pressure gauge on your boiler. If it's too low (typically below 1 bar), you may need to re-pressurise it according to your manual.
Thermostat: Is your thermostat set correctly and calling for hot water?

Electric Water Heater: Check its power supply and if any RCDs or circuit breakers have tripped.

Important Safety Note: For any internal boiler issues beyond checking power or repressurising (which you can do yourself if comfortable), you must call a Gas Safe registered engineer. Attempting to tamper with gas appliances is dangerous and illegal.

Step 5: Check for a Burst Pipe on Your Property

A burst pipe is a plumbing emergency. While it often results in a visible leak, it can also manifest as a sudden loss of water supply.

Signs to Look For:

A sudden, significant drop in water pressure before the supply stops.
Damp patches on walls, ceilings, or floors that appear suddenly.
The sound of running water when no taps are open.
Unexplained puddles in your garden or near your external stopcock.

Immediate Action: If you suspect a burst pipe, immediately turn off your main stopcock to prevent further water damage. Then, contact an emergency plumber without delay.

When to Call a Professional Plumber

If you've gone through all the above checks and still have no water, or if you've identified a problem you can't safely fix yourself, it's time to call in the experts. Here are situations where professional help is essential:

You've confirmed the issue isn't with your water supplier, and your stopcock is fully open, but still have no water.
You suspect a burst pipe but can't locate it or stop the leak effectively.
You have frozen pipes that you can't safely thaw, or you're concerned about potential damage.
You have no hot water, and the boiler or water heater checks don't resolve the issue (remember, Gas Safe for gas boilers).
You're uncomfortable performing any of the DIY checks or repairs.

Emergency plumbers in the UK typically charge a callout fee, which can range from £80 to £150, plus labour and parts. For a straightforward fix like freeing a seized stopcock or clearing an airlock, you might expect to pay between £150 and £300. A more complex issue like a burst pipe repair will naturally be more expensive, potentially running into several hundred pounds depending on access and damage.

Frequently asked questions

What if only one tap has no water?

If only one tap is affected, it's usually a localised issue. Check the isolation valve for that specific tap to ensure it's fully open. It could also be an airlock in the pipe leading to that tap, or a faulty tap mechanism itself. Try opening nearby taps to see if the flow improves.

How do I know if my pipes are frozen?

Signs of frozen pipes include no water coming from taps during cold weather, visible frost or ice on exposed pipes, or a strange gurgling sound when you try to use a tap. Often, the cold water tap in an unheated area (like a garage or loft) will be affected first. Be extremely cautious and gentle if attempting to thaw them yourself.

Should I call my water company or a plumber first if I have no water?

Always call your water company first if you suspect the issue is with the main supply to your property or area. Check their website or social media for updates. If your neighbours also have no water, it's almost certainly a supply issue. If only your property is affected, and you've checked your stopcock and ruled out external supply problems, then it's time to call a professional plumber to investigate internal issues.
