hi guys/jax, i guess as long as they were in before the heat pump boys they say nothing the certificate will prove who was in the wrong so just wait for a problem. All the regulating cannot stop problems caused by someone else, we as tradesmen bear the brunt of idiots who know no better so they come down on us even harder, i was changing a hot water cylinder in a fish&chip shop recently and came across this, have a look at the pics,what can you do?

The problem Robbo is if for any reason you are called back to property to turn the gas back on - then you need to make a call as to the safety and legality of a heatpump too close to the GMS.  The outside unit has a compressor and therefore could be considered a potential source of ignition - all based from the measurement of the vent (5261).  In this case you shouldn't turn in back on if it's too close and you have to report it to ESS on the form on their website.  None of this will be speedy and the gasfitter will be left, as usual, standing alone.  Once you've seen it you don't have the luxury of walking away and pretending you don't know.

Hi guys as gas fitters/engineers
We have set an example to the board and our customers this will sometimes incur costs on us but we are the experts and have to be seen to be
I recently found a dangerous installation and immediately turned off and isolated and informed the installer who was not very happy
I have to say he never reported me for disconnecting the appliance  and after thinking about further he came and thanked and even offered me a job but can only work for myself jd
