Further actions I have taken.....
I have restarted my fibre modem & router,
cleared all cache & data, purged the browser and reinstalled.
Guess what..no change, still error 1007.
I tried a twitter to @plusnethelp but have not had any response.
The bank say their IT dept may be able to look at the problem on Wednesday. The problem, happily, only affects this group of companies......I may be leaving them soon....
