Postal mails (even ordinary, Par Avion) may reach fast from UK to Bulgaria. As there are many flights from London to Sofia per day.
The question is from which part of UK is the mail and to what destination is to reach in Bulgaria.
Overall 5-7 working days would be good enough. Priority and Courier mails reach faster.
Par Avion (by air) letter one week. Parcels and registered postal mails 2 weeks
The post service is much better these days in Bulgaria and new post is processed much more quickly. We can receive mail from the UK in as little as just 3 days, parcels also. It's never more than 7 days anymore. See more information on moving to Bulgaria: http://www.questbg.com/lifestyle/life/2247-moving-to-bulgaria-from-uk.html
