Flue Inspection Hatches


A new regulation was introduced in 2010 that requires all flues (the exhaust pipe on your boiler) that pass through the ceiling, walls or some other cavity or box before exiting the house have inspection hatches fitted so that the flue can be visually inspected.  This is becoming an urgent matter because since 31 December 2012, if these hatches are not fitted, any Gas Engineer that inspects or does any work on the boiler will be obliged ask to turn off the boiler until they are installed.

All Gas Safe registered engineers need to be able to see the flue if it runs into areas of void.  This is as part of essential safety checks whenever the boiler is worked on.  A flue in poor condition, combined with a room-sealed boiler that is not working properly, could put you and your family in danger from carbon monoxide poisoning - potentially fatal.

Our Gas Safe Heating & Boiler Engineers are asked to inspect a lot of installations to establish whether inspection hatches are required.  The following applies:


    • Inspection hatches are NOT required if your boiler is attached to an external wall of the building and the flue goes straight out the external wall.
    • Inspection hatches ARE required when your boiler is situated somewhere in the interior of your house and you do not know where the flue goes.
If we need to fit an inspection hatch, you can be assured that it will be a neat installation (large enough to fit at least a head through, sometimes slightly bigger) finished so that its not out of keeping with the remainder of the area.  When we install your inspection hatch, we will quote you the rates prior to commencement of the hatch fit.  All installations will be in line with the GAS SAFE Register's best practice rules.
If you believe you need an inspection hatch fitted or are unsure, you should give our expert team a call without delay.  Although having no inspection hatches doesn't automatically make your boiler and flue a hazard, it will most certainly be condemned by a Gas Safe engineer and it could spell impending danger for your home and family.

Our heating team not only deal with boilers and flue hatches, but are also trained and able to take care of other plumbing & heating issues around your home, office, shop or unit.
