Connection time between Terminals 3 and 5 at LHR.

I will be arriving at LHR's Terminal 5 at 1830 from Paris CDG (hopefully on time!). I then depart on QF2 at 2035 from Terminal 3. Is the 2 hours enough time to get to T3?

should be - they say allow 90mins - depends if you catch the bus times on disembarking from BA flight - normally run every 10-20mins so you should be fine - just another security check when you get to T3 to get through though!

Yes it should most likely be, be sure to be at gate around 20 min before departure though.

If your flight is delayed cost should be waived by the airline and they will most likely put you in a hotel or on the next flight

The cost would be waived by the airline assuming the flights are booked on the same ticket

Plenty

Thanks for your answers.  The flights are on the same ticket so it's reassuring to know about the waiving if any delays at CDG - thanks to TomGoddardd and Hayden.

You could also use the Piccadilly Line that connects from the Terminals 1,2,3 to the Terminal 5 Station. This wouldn't take too long to get there.
