Hi Anthony, welcome to the forum.
This is the site to order from. The certificate is currently £9.25 I believe. I'm not sure if there is an additional charge if you are abroad. Anytime you wish to order a certificate, use this link. There are many other sites out there that will charge you more and make you believe you are ordering direct. You will need to register and you will also need the info Gloria found for you which I have copied below. If you struggle with the ordering process online, their phone number is +44 (0)300 123 1837 (8am to 8pm Monday to Friday. Saturday 9am to 4pm). I think you can place the order over the phone.
