"I and many others here are still tax payers in the UK, even as non residents.
In conclusion, I would ask that given this pretty simple solution, could not our Embassy return to assisting us in this matter?"
And that's the point that the UK Government conveniently wish to forget. You are, and have been paying for "consular services". Your suggestions seems very reasonable and logical, but will no doubt fall on deaf ears, there's a pool party and Christmas bash to get organised don't you know. So far to busy to be offering practical solutions to aid the expat community.
Why bother being proactive and and help resolve matters when they can just ignore real issues.
