in early april 2009 my hotel room was broken into in bangkok and amongest other items stolen was my passport

a new uk passport was issued in bangkok and it will expire in april 2019

Can i head along to a uk consulate or embassy(in thailand or elsewere)and simply hand over my existing passport and renewal fee and be issued with a new 10 year uk passport within say several weeks of a renewal application?

No - go to gov.uk  renew passport and click Thailand and then do what it says.

Did you use the words simply and Thailand in the same sentence?

I have cut & pasted someone's contribution on this forum to my computer but forgot his name.  It spells out EVERY step + requirements.  I am ashamed to say I didn't copy his name but everything went as he explained it.  Check out this topic & find it.  To this kind contributor - thank you this is the most detailed & clear explanation of any process on this site.  If unsuccessful PM me & I will forward it to you.

All the info you need can be found here by going through the steps here. https://www.gov.uk/overseas-passports

Here you have to apply and pick it up in person in Bangkok. Average time to get a new passport is 2 to 3 weeks.

Just did mine this month all pretty painless apart from 2 trips to bkk to apply and then to collect 

Very simple to get a new UK passport in Bangkok.  Mine was ready in 8 days!

 

Go to VFS which is the official outsourced office for UK passports located at.  They are very helpful, speedy and much less hassle than courier to the UK etc.

I only see info on that page for visa applications. Nothing about applying for a UK passport.
