Emergency Boiler Lockout

If your boiler keeps locking out and you have no heating or hot water, this service provides urgent, safety-led diagnosis and repair. The aim is to make the system safe first, identify the fault that is triggering the lockout, and restore heat as quickly and reliably as possible.

More information

What an emergency boiler lockout visit covers

A repeated lockout is usually a sign of an underlying fault rather than a one-off reset issue. The visit focuses on safe fault finding and practical restoration.

  • Safety checks on the boiler and heating system, with Gas Safe compliant working where required
  • Fault diagnosis to identify why the boiler is locking out
  • Targeted repairs and adjustments to restore operation where possible
  • Advice on immediate steps to prevent repeat lockouts
  • Clear explanation of findings, options, and likely next actions if parts are needed

When this service is the right fit

This service is most relevant when:

  • The boiler has locked out more than once in a short period
  • You have no heating or hot water, especially in cold weather
  • The boiler runs briefly then shuts down and shows a fault code
  • You are managing a rental property and need essential services restored quickly
  • A small commercial space needs heat back to remain operational

How the visit works

You will be asked a few quick questions about symptoms, fault codes, and recent changes to the system. On arrival, the engineer will carry out checks, pinpoint the cause, and confirm what can be done immediately.

Where a safe, lasting repair can be completed on the spot, it will be done. If the issue requires specialist parts or further work, you will be given a clear plan and next steps.

After the lockout is resolved

Once the boiler is running again, you will be advised on any settings, maintenance, or system issues that could trigger repeat lockouts. If follow-up work is needed, you will know what it is, why it matters, and the priority for completing it.

Frequently Asked Questions

Why does my boiler keep locking out?
Repeated lockouts are often caused by low pressure, ignition problems, blocked condensate pipework, sensor faults, or circulation issues. A proper diagnosis is needed because repeatedly resetting the boiler can mask the underlying fault.
Is it safe to keep resetting a boiler that has locked out?
Not always. A lockout is a safety response, so repeated resets without diagnosis can lead to further damage or unsafe operation. If you smell gas, turn it off if safe to do so, ventilate, and call the gas emergency number.
Can you attend outside normal working hours?
Emergency lockouts are often handled as urgent call-outs, including evenings or weekends when available. You will be told the expected arrival window and any limitations before attendance.
What information should I have ready when I call?
Note the boiler make and model, any fault code on the display, and what happened just before the lockout. It also helps to know your system pressure reading and whether you have heating, hot water, both, or neither.
Will you be able to fix it on the first visit?
Many lockout causes can be resolved on the spot after testing and adjustment. If a specific part is required, you will be told what is needed and the safest way to keep the property running until the repair is completed.
