If you’re buying or putting together a first aid kit for home or work, buying first aid supplies or putting together a survival kit, do try to buy British.
If you are ordering a first aid kit for your workplace, ask your supplier about the provenance of both the container and the contents and insist on getting British made for both.
It may take a bit of research to find British made. Here is what I have found so far. If you find more manufacturers and supplies please let me know.
