Emergency Heating Water Leak

An emergency heating water leak can quickly cause damage, drop system pressure and leave you without heat. This service focuses on fast isolation, clear fault-finding and effective repairs to stop the leak and get your heating system working safely again.

More information

What this emergency heating water leak service covers

When a leak is coming from pipework, radiators or heating components, the priority is to stop the water, protect the property and restore safe operation.

  • Rapid isolation of the heating circuit to reduce flooding and water damage
  • Diagnosis of the leak source (radiator, valve, pipework, joints, pumps and other fittings)
  • Targeted repair or replacement of failed parts where possible
  • System pressure checks and safe re-pressurisation when appropriate
  • Temporary make-safe measures when a permanent repair needs follow-on parts
  • Practical advice on drying out, monitoring and preventing repeat leaks

When to call for an emergency

This service is suited to situations where waiting risks damage or loss of heating.

  • Water leaking from a radiator, valve or heating pipe
  • Repeated pressure drops on the boiler with visible signs of water
  • Leaks affecting ceilings, electrics, flooring, or neighbouring properties
  • You have isolated water where possible but the leak is ongoing

If you can do so safely, turn the heating off and contain the leak with towels or a tray until help arrives.

What happens during the visit

The work is structured to keep disruption low and decisions clear.

  1. Initial safety checks, then isolate the heating circuit and control the leak.
  2. Locate the fault and explain the likely cause and repair options.
  3. Complete the repair or make the system safe, then test for leaks and stable pressure.
  4. Confirm what has been done and what to watch for over the next 24 to 48 hours.

After the repair

Once the leak is stopped, the next step is ensuring the system stays reliable.

  • Guidance on bleeding radiators and maintaining correct system pressure
  • Recommendations if corrosion, sludge or ageing valves are contributing factors
  • If a temporary repair was required, a clear plan for the follow-up fix and any parts needed

Frequently Asked Questions

What should I do first if my central heating is leaking?
Turn the heating off and, if safe, isolate the boiler and any local valves to limit water flow. Catch and contain water to protect floors and electrics. If water is near electrical fittings, switch power off at the consumer unit and call for help.
Can you repair a heating leak without turning off all my water?
Often yes, because many heating leaks are on the sealed heating circuit rather than the mains supply. Where isolation valves are available, we can usually limit disruption. If valves have failed or the leak is on shared pipework, wider isolation may be necessary for safety.
Why does my boiler pressure keep dropping?
The most common cause is a leak somewhere on the heating system, even if it is slow or hidden. It can also be linked to a faulty pressure relief valve or expansion vessel issue. A visit focuses on finding the cause, not just topping up the pressure.
Do you provide out-of-hours emergency call-outs?
Emergency leak support is available when urgent action is needed to prevent damage or restore essential heating. Availability can vary, so it is best to contact us with the symptoms and location of the leak. We will confirm the earliest attendance and next steps.
Will you be able to fix the leak on the first visit?
Many leaks can be repaired immediately with standard parts and tools, especially radiators, valves and accessible pipework. If a specialist part is needed, we can make the system safe and stop the leak, then return to complete the permanent repair. We will explain the options before proceeding.
