Hi Peter
You can apply online at
www.gro.gov.uk using the references quoted.
At the moment you have 2 choices for the death cert
a certificate in the post for £9.25 or a pdf by email for £6
but this is a 3 week trial and may stop sooner if the GRO sell more than the 45,000 copies they have allocated to this project
The marriage cert will cost £9.25 as it is not part of the project.
Whatever you chose you will need to register with the site.
