Please can someone help me,
I have tried countless times to contact the consulate, but have had no luck.

Last year I lost my passport but it had expired already anyway.

I have a copy of my original Birth Certificate issued from Portugal.
How do I now obtain my ID so I can get my Passport? I live in Great Yarmouth, do I have to go and apply in person at the consulate for my ID or can I do it by post just like how I got my Birth Certificate?
If I have to go in person, How can I arrange an appointment? And what all documents do I need to take with me?

If I can do it by post or online, how do I go about doing it?

How much does the ID cost and how much does the Passport cost

If you can help me in any way , with any info please do I will really appriciate it

Please someone help, I am stuck

You need to email the consualte in MANCHESTER, not london.

They won't pick up the phone, you must email him.

In the email, ask for an appointment to see him.
He will tell you the documents you need to take with you on the day.

It's a lengthy process.

Hope this helps
