The fastest public transport route from Heathrow to
Southwark is by Heathrow Express train to Paddington,
then by Tube (Underground). I suggest the Bakerloo Line
from Paddington to Baker Street, then a level interchange
to the Jubilee Line which will take you to Southwark. The journey itself
takes about an hour. About 10-15 minutes
longer but much cheaper is an all-Tube route using the
Piccadilly Line from Heathrow.

Since the main hotels in Southwark aren't particularly near to the tube, he
would probably be quicker to get the Heathrow Express to Paddington, get the
Bakerloo line to Waterloo and then get a taxi for the last part of the
journey. If there are two people in his party, a taxi all the way from
Heathrow to Southwark would be approximately comparable in price and time
with the Heathrow Express route... if there are three or more people, the
taxi would be much cheaper than the Heathrow Express, although nowhere near
as cheap as going all the way by tube.
