US Citizen Rating in England. How will my US Pension's be taxed?

[EHC]

I am really confused. At 68 year of age moving to England and what tax obligations I will have is complicated for me. My wife is a duel U.K. And US citizen having been born in England and naturalized in the US m. I am US citizen and will remain a US citizen (always). I plan to retire in England with my wife but if I can't make the adjustment or if something were to happen to my wife I would return to the US. I plan to periodically return to the US regardless to visit family and friends.

My wife and I both get Social Security. Additionally I receive a US Army retirement, VA Disability Compensation and an annuity/retirement from the Texas Retired Teachers System (a state pension fund) from which I retired as a teacher (my second career).

What I specifically need to know is will the US, UK, or both tax each of the following:

1. VA Disability (non-taxable disabiyincome in the US).
2. US Army Retirement pay.
3. Texas Retired Teacher pension.
4. Social Security Income.

Also ....

If I have any of these pensions deposited to a UK bank account will that effect my UK and/or US taxation?

If I have it deposited to a US bank and then transfer funds to my UK bank account will that make a difference?

Are there any UK residency time requirements that pertain to the aforementioned with respect to taxation?

Are their any other problem areas I might encounter with respect to taxation that I am not aware of?

Who in the US and U.K. can I write to or email in an official capacity regarding the aforementioned?

Do you have any advice or recommendations to help me keep my tax situation in the U.K. to a bare minimum while ensuring I keep everything legal? As senior citizens and the high cost of living in the UK and fluctuating exchange rates us seniors on fixed incomes need to be very careful.

I know this is a rather lengthy information request but any verifiable help that you can provide will be sincerely appreciated.

Thank you,

EHC
