Unsafe boiler flue Surrey installations are a serious risk to health and safety. Our engineer recently found a flue discharging directly next to an open window, which could allow harmful gases to re-enter the property. This blog explains the dangers, legal responsibilities, and what action should be taken immediately.

WHAT MAKES THIS FLUE INSTALLATION UNSAFE

In this case, the flue was positioned too close to a window, allowing exhaust gases to flow back inside.

This is dangerous because:

• Flue gases contain carbon monoxide
• Open windows can draw fumes back indoors
• Occupants may be exposed without warning

This type of unsafe boiler flue Surrey issue must be corrected immediately.

WHY THIS IS A SERIOUS SAFETY RISK

A boiler flue is designed to safely remove combustion gases from a property.

When incorrectly installed:

• Carbon monoxide can enter living spaces
• The risk increases when windows are open
• Long-term exposure can be fatal

This is not just poor workmanship — it is a major safety hazard.
