The stays, and why

Our pick

Aerotel London Heathrow

Inside the terminal5 min to check-inNo transfer cost

Room, typical: £110–£180
Transfer: £0
Typical total: £110–£180

Who it suits: Most overnight connections at Terminal 3, especially gaps of eight hours or less.
Why we would choose it: It is in the Terminal 3 arrivals hall. You walk from arrivals to a bed in minutes, and back to departures just as quickly, paying only for the hours you book.
The compromise: A compact, functional hotel inside an airport terminal, not a full hotel.
Worth paying more?: This is about fit, not price. On a connection, the shortest route to a bed and back is usually what you want.

Also consider

Hilton Garden Inn London Heathrow Terminals 2 and 3

Pedestrian underpass10 min to check-inNo transfer cost

Room, typical: £130–£220
Transfer: £0
Typical total: £130–£220

Who it suits: Long connections where you want a full hotel and will be awake to use it.
Why we would choose it: A full hotel reached through the central-area underpass in eight to ten minutes, under cover and with nothing to catch.
The compromise: A longer walk with bags than staying inside the terminal, at a rate that reflects being the only walkable full hotel.
Worth paying more?: Yes if you want a full hotel. No if you only need to sleep.

Best valueLowest total

Renaissance London Heathrow Hotel

Hotel Hoppa bus25 min to check-inRuns 04:00 to midnight

Room, typical: £80–£140
Transfer: £26Bus, £13 return each, two adults
Typical total: £106–£166

Who it suits: Connections of ten hours or more, with a flight after 07:00.
Why we would choose it: A full hotel a bus ride from the terminal, usually for much less, and a long gap has time for the journey.
The compromise: The bus runs about every half hour, so a short gap loses a good part of the night to waiting.
Worth paying more?: For most gaps we would pay for one of the two above. Choose this only if the gap is long.

Check before you book

Whether you can leave the airport at all. Check the entry rules for your passport before you plan to go landside, and whether your bags are checked through or you must collect them.
Count the hours you really have. Take away immigration and baggage on the way in and security on the way out, and see what is left for a bed.
If you leave from a different terminal, the guide to getting between terminals covers the journey, and how long to allow.
How many hours you need, if you choose the hotel inside the terminal. It is priced by the hour.

Good to know

How we chose

We worked out the hours left for sleep after the journey each way, and ranked the stays by how little the transfer takes from them. We are independent and this is not an official airport website.
