Best places to visit in the uk?

As you are born and bred British, and only moved away two years ago, it would be helpful if you could tell us where you have already been, and any area where you are considering a visit.

So, what areas do you know well?

I know from experience as a teacher that UK residents with an Islamic background are unlikely to have much knowledge of the "usual" cultural sites. (especially cathedrals, art galleries or British historical sites). Quite often, "best" seems to be equivalent to shopping malls and amusement parks. (Note that "shops" are cited as one requirement).

ive been to belfast, wales, swansea, holyhead, newcastle and london

I found the "Jack the Ripper" walk to be especially refreshing.

The best way to find the best places to visit in UK or another country is for me to follow my interestes. In your case - yours.
What are you interested in? Medivial England, modern art, beautiful gardens, Inspector Barnaby?
When you know your special interest get inte Google or/and buy a book which tells you all about where and when you can experience your interests.
It certainly wont make your trip to UK interesting if I tell you what to do because I want to see it.
Just because all tourists go to a place does not mean it is the best place to visit.
I would never recommend anybody to go to Harrod´s and still it is full of tourists.
If I were in London now I would sign up to see the Viking exhebition in British Museum. That does not mean someone else would like to see it.

England, Wales, Scotland and Northern Ireland, the United Kingdom has long been a favorite European tourist destination for many because of its beautiful countryside, historic cities, topnotch museums and outstanding theaters.
