I've had tool insurance since I last got cleared out. I have a policy for the tools in my van (which is a seperate policy from the van insurance so I don't lose my no claims bonus if I have to claim) I also have tool cover wrapped in with my public liability. That covers my tools on site. (As long as the site is secure). All in all it costs me about £150 a year. Which covers £5000 of tools.
I lost at least £5000 quids worth last time. So its good peace of mind money. I would still be gutted. The worse thing would be to lose my hand tools, as they are more personal. If I lose an SDS I'll buy another one, just the same. If I lose a box of hand tools, there will be 30 handy little things I need to replace, from angled screwdrivers, to bent nose pliers. Getting hold of quality bent nose pliers is a mission. Trust me I know! Finally Toolstation started to stock them.
When we last got done, they took all the powertools (of course) and one box of hand tools. Mine. Typical. They also took a canterlever box I had full of unusual brass fittings. I had built that box up over years. I was well gutted about that, as I knew it would all go to a scrap man for a fiver.
