Hi Ken,
Here's the link to the online GRO site for certificate ordering:
www.gro.gov.uk/gro/content/certificates/That should tell you all you need to know. There is a part of the form where you can ask them to check references including parent's names, spouse names etc. They say that if you have done your own searching in the GRO indexes and have found more than one reference to the name you are researching, or are unsure which is the entry you require, they offer reference checking online. The charge is £7 for action on the first entry, which includes the cost of the certificate, and £3 for checking each subsequent reference against the information you have provided. You must give one piece of information that you are sure will appear on the certificate, e.g. the exact date of the event. A certificate will only be issued if the entry matches the checking point you give them.
Or if you know which is the local register office you can ask them to check for known details before you buy
