FindMyPast have announced that the much awaited 1939 register will be released on Monday 2nd November [link here], they do not mention a time, but I imagine whatever time of day it will be, that the website will probably melt down!
To view a household from the register will cost £6.95 (this is above the cost of a subscription), although a bundle of five households can be purchased for £24.99, so costing about £5 per household. Reading subscribers views on the announcement there are many people who are very angry about the extra charges.
However, I have managed to gleam from some of the replies by FindMyPast to the comments a little more about how the redacted information will work. Anyone over the age of 100 years old will be visible. If someone, who would now be less than 100 years old died before 1991, then they will be visible (I assume that the NHS who used this document were still updating it until 1991). If someone died after 1991 it will be necessary to submit a death certificate to have the record unlocked.
I know what I will be doing on Monday morning!
