Again , i can only speak for the authority i work for , but they would do this whichever way you wanted.
If you wrote to them , phoned them , or emailed them , they would respond to your request.
As i say , as long as they have the name and date of death , then it only takes seconds for them to come up with a grave number ( as long as the person IS in one of our Cemeteries).
Then it would be up to you really - if you could visit , then they'd send you a plan of the Cemetery , and make arrangements for you to meet one of our Cemeteries staff - who would happily show you the grave.
If you weren't in a position to visit the Cemetery , then it wouldn't be a problem for us to photograph the headstone (if there was one) , and send the photo to you.
They really are obliging , and would help in any way they could - dont feel cheeky - we're here to help people after all

Obviously (as i've said) , i can only speak for the bereavement services /Cemeteries depts in Stockton-on-Tees , but if you are alluding to Stockton then let me know and i'll post the contact details.
Hope you find what you're looking for.
