I found the best thing to do is talk to the person that services the extinguishers where you work, my workshop has
3 2kg powder distributed around the place
1 7kg foam
1 large co2
2 smaller spray type water
All free as they had reached their 5 year limit, but they are stored pressure units with guages so I know they are serviceable and if any of them look a bit iffy he gives me more of them for free as it saves him the cost of disposing of them, everyone wins
