I’m hoping someone could help me.
My 2005 Honda jazz feels like it’s going to stall when on low revs/at a complete stop. I have noticed this only happens when it’s in gear. When I put it into park or neutral, it’s quieter, and doesn’t “rattle” .
At first I thought it was because of having the air con on, but have discovered it happens even with air con off ( although I have booked in to get the air con regassed).
Any helpful comments would be greatly appreciated.

Internal combustion engines normally run rough if they drop below its minimum happy idle speed . As you say it can slow down even more if its under a bit of extra load, such as turning the air conditioning compressor, or even the alternator if its under extra load for headlights, heated rear window etc.
Usually the cars ECU, (electronic control unit) uses various sensors to detect if its running slow or rough and speeds it up and automatically adjusts settings.
Unfortunately there are many possible reasons why the ECU may get it wrong, or unable to improve the running. . Faulty sensors, clogged valves, old spark plugs, etc. Although these are may be maintained during a service its not uncommon for garages to take short cuts as cars will often run well enough for years even if they save themselves some time and costs on parts.
If the car is overdue a service and its done properly , this may cure the problem. There are one or two things you might be able to check yourself such as whether the air filter is clogged with dust and bugs etc, or an air leak in the pipes from the filter to the engine. But most causes may need an experienced mechanic to check for fault codes etc using an OBD2 scanner.

Jazz has had a full service in February of this year. Replaced spark plugs and fuel filter. It has never had this problem before. Just over 102,000, and had just been driven around town. It may be worth noting that it’s been very hot and dry weather since this started ?
