Likely journey time on a Friday evening.... trying to work out when i need to be arriving into St P to be at T3 intime for VS17 to Newark.... so early evening time.

Thoughts welcomed

HEX takes 15 mins from Paddington to T3, plan 20 mins for tube from StP to Paddington, pad with 5 mins for ticket buying / delays ... so say 40 mins from StP to T3. Arrive at StP appropriately.

Depends how critical it is to minimise time in T3.

Doing underground, you are reliant on Circle/Ham-and-city line, which can be problematic, often having delays. If it goes well, it's a breeze, but could easily take 40 mins if there are issues.

Taxi would be more consistent, allow 30 minutes.

Because of the requisite tube journey, ticket buying (if applicable) and potential wait time at Paddington (could be 15 minutes if you hit it just wrong), it's a very expensive and not particularly quick or convenient way to get from StP to LHR.

I recommend you take the Underground, Piccadilly line, direct. Comparing trip times:

Whichever way you do it, first you have to allow, say, 10 minutes from alighting your train at StP to boarding an Underground train, including likely maximum wait time. Add that to:

-: via the HEX, 20 minutes by tube StP to Paddington, 5 minutes for moving within the station, up to 15 minutes awaiting departure and 15 minutes trip time. That's 55 minutes maximum.

-: via the Piccadilly Line, about 60 minutes.
