I finally received my documents from VHI today regarding my switch from Plan B options to Teachers plan for Hubby & I .I am delighted to see the cover is almost identical to Plan B/ B options. The cost was indeed 772 Euros each which was a massive saving of over 1,000 euro for us. Although I am a former teacher I was not aware Vhi had this plan until recently. But even I did not get the discounted rate. But I am not complaining, as I'm delighted with the amount I have already saved. so thanks to the OP and also to Nova Flare and Pj111 once again for your help & advice.
