The General Register Office in London is conducting a trial of PDF versions of birth, death, and marriage certificates for 6 pounds instead of 9+ pounds as in the past. Records are not immediately viewable. Instead, after payment the records are sent to the purchaser via email as a PDF file. The trial period is for a limited period and set amount of certificates, but those familiar with the past methods of ordering certificates online say that it is a really good deal.

My thanks to newsletter reader Linda Pauwels for telling me about the new procedures.
