Trendy is where you renew your Passport. You need a Certified Translation first. Outside the British Embassy in Wireless Road have Certified Translation Agents that are very good and reasonable. Better than the ones around Trendy Buildings in my opinion
A certified translation is adequate. One that is signed and stamped. If you walk out of the Embassy's gates there are agents offering these services there.
