Thanks everybody for your advice! I think I shall save my pennies and subscribe to findmypast instead - especially when they do have the 1911 on line, as Kite suggests. I have done a pay-to-view thingy on findmypast occasionally, but reckon that must cost a lot overall when it boils down to it! As WorldVitalRecords seems to be very American records orientated, I can't see it will be too informative as regards my family as very few of 'em even went north of Watford....
