Usually no. Heathrow wins for most travellers.
The ticket price you see on a flight-search site is only part of the story. Once you add the cost of getting to the departure airport, checked baggage, seat selection, and — crucially — the transfer from the arrival airport into central London, the picture can shift dramatically.
Heathrow is connected to central London by the Piccadilly line (off-peak ~£6) and the Heathrow Express (~£25). Stansted relies on the Stansted Express train (~£20–25) or a coach — and after roughly 23:00, only a taxi is realistic, which can cost €70–90.
This is why a €58 Stansted ticket can produce a €204 journey, while a €126 Heathrow ticket can land at €171. The airport you fly into shapes every cost that follows.
Only when two things line up: the fare gap is wide, and you’re travelling light.
Choosing Stansted means accepting more decision debt — a secondary airport farther from the city, a late arrival window, a night-only transfer option, and greater dependence on estimated taxi costs that can swing the comparison.
