(ASTA Intertek also approve UK mains plugs, more details coming soon on this page)
BSI has a facility for checking the license number of a BS 1363-1 UK mains plug.
- Go to the product directory page on the BSI website
- Fill in the license number on the plug into the form field “Certificate number…” (see below)
- Hit “Search”
Hopefully the number you have entered is genuine and you are presented with some search results:
You can then click on the line you are interested in and check the details of the plug against the sample you have.
