If taking Heathrow Express: don't take Tube from Paddington—walk 10 min via Praed Street/Westbourne Terrace (often faster than waiting for Circle/H&C). Or use Elizabeth Line from Paddington (2 stops, 4 min).
For most travelers, the Elizabeth Line is the smart choice: direct, affordable, modern. Heathrow Express remains for when minutes matter more than pounds.
