Boiler Lockout Reset & Repair

What boiler lockout reset and repair covers

Boiler lockout is your boiler protecting itself after detecting a fault. This service is designed to get you back up and running safely, and to stop the lockout coming back.

Typical work includes:

• Reading fault codes and checking the boiler’s operating sequence
• Testing key components linked to ignition, flame sensing and combustion safety
• Checking system pressure, circulation and signs of leaks that can trigger shutdowns
• Inspecting condensate drainage and frost related issues (common causes in cold weather)
• Checking electrical connections, controls and safety interlocks
• Repairing the fault where possible on the day, or arranging parts and a return visit
• Completing relevant safety checks before leaving you with a working system

When this service is right for you

• Your boiler locks out repeatedly or needs frequent resets
• Heating or hot water cuts out intermittently, especially at peak times
• You have an error code that returns soon after restarting
• The boiler tries to fire but fails, or you can hear cycling on and off
• You need a reliable fix for a tenanted property or small commercial premises

How the visit works

1. Initial checks: we confirm symptoms, boiler model, and any recent changes to pressure, controls or power.
2. Diagnostics: fault code interpretation and targeted testing to identify the root cause, not just the symptom.
3. Repair plan: where possible, you will get clear options before work proceeds, including what’s urgent and what can wait.
4. Repair and verification: repairs are completed and the boiler is run through checks to confirm stable operation.

Timescales depend on access, the fault type and parts availability, but the aim is always to restore safe operation with minimal disruption.

After the repair

You will be advised on practical steps to reduce future lockouts, such as pressure management, filter cleaning schedules, or control settings. If the issue points to wider system problems, you will get a clear explanation of next steps and the best order to tackle them.
