The two hotels, and the free breakfast
Two hotels carry the Holiday Inn Express name near Heathrow, and they do different jobs. One is on the airport at Terminal 4, a covered walk from the terminal; the other is off the airport near Slough, a drive from Terminal 5. What they share is the brand's defining feature, the Express Start breakfast built into the room rate, which is worth real money at an airport where most hotels charge for it separately.
| Hotel | Distance | Getting to a terminal | Parking |
|---|---|---|---|
| Terminal 4 | 5-min walk to T4 | Covered walkway to T4; free transfer for T2, T3, T5 | £35/day underground, 125 spaces |
| Terminal 5 (Slough) | 10-min drive to T5 | Car, taxi or booked transfer; no free shuttle | £16/day on site |
Operator distances and parking rates. Prices move; treat them as the going rate. Both include the Express Start breakfast in the room rate.
The naming is clearer than at some chains, but the terminal in the title still matters: only the Terminal 4 hotel is at its terminal. The Terminal 5 hotel is named for the terminal it is nearest to, not one it stands beside, so a Terminal 5 flyer without a car should weigh the drive before booking it over an on-airport option.
Terminal 4: the walk-to hotel
The Terminal 4 hotel is the reason the brand ranks at Heathrow. It sits on the airport, joined to Terminal 4 by a covered walkway, about a five-minute walk to check-in with a roof the whole way, and it shares its building with the Crowne Plaza, the two holding around 700 rooms between them. Breakfast is the Express Start buffet, included in the rate and served from 05:00, early enough for the first flights, and there is underground secure parking for up to 125 cars at around £35 a day, with a 2-metre height limit.
The catch is the terminal it serves. Terminal 4 is the SkyTeam and Gulf-carrier terminal (Air France, KLM, Korean Air, Qatar Airways, Etihad and others), so the walk only pays off if you fly from T4. For a Terminal 2, 3 or 5 departure you ride the free inter-terminal transfer, the Elizabeth line or the free airport coach, from T4 to the central area first, which turns the short walk into a longer journey with the change. Booked for the right terminal, it is a genuinely cheap on-terminal bed with breakfast thrown in.
The Terminal 5 hotel near Slough
The other Holiday Inn Express is a 300-bedroom hotel out near Slough, about a ten-minute drive from Terminal 5, off the airport. It carries the same free Express Start breakfast, served from 06:30 on weekdays and a little later at weekends, and self parking runs at around £16 a day, less than half the Terminal 4 rate. Its family rooms take two adults and two children, with interconnecting rooms for larger groups, which suits a family driving in the night before a flight.
The trade is the transfer. There is no free airport shuttle here, so you reach Terminal 5 by car, taxi or a booked transfer, and the ten-minute drive is real rather than a walk. That makes it a driver's hotel: cheaper than the on-airport options and comfortable for a family, but only convenient if you have a car or are willing to pay for a transfer. For a walk-to-the-gate stay at Terminal 5, the on-airport hotels are the Sofitel and, by pod, the Thistle.
Which to book for which flight
For a Terminal 4 flight, the Terminal 4 hotel is the pick: a five-minute covered walk to check-in, breakfast included, and a fair rate for an on-terminal bed. For a driver on a budget, especially a family, the Slough hotel near Terminal 5 is the cheaper option, with the same free breakfast and low parking, as long as you are content with the drive. Confirm which terminal your airline uses before booking, because neither hotel helps much if you are flying from the wrong side of the airport.
The comparison that matters most at Terminal 4 is with the Premier Inn on the same walkway. The two are close on location and rate, and the deciding factor is usually breakfast: the Holiday Inn Express includes it, the Premier Inn charges for it. Price the room plus breakfast for both on your dates, and for two people who will eat a cooked breakfast before a flight, the included version often wins. Drivers going away for a week should ignore the nightly parking rates at either and price a hotel-and-parking bundle or pre-booked long-stay parking instead.
Rooms, breakfast and booking
Rooms follow the Holiday Inn Express formula: straightforward, well-kept doubles and family rooms, air-conditioned, with a decent shower and a work surface, pitched at a comfortable night rather than a stay in its own right. The point of the brand is value with the essentials covered, and the Express Start breakfast is the essential it covers that others do not, a buffet of pastries, cereals, yoghurts, hot items and coffee, included and open early.
Prices are dynamic, and the Terminal 4 hotel moves harder than the Slough one because of its walkway location. Book directly with the operator rather than a reseller, where amendments are simpler and the breakfast and any member rate are clearer, and for a flight booked well ahead the flexible rate usually earns its small premium, since flights move and a room you can change beats a cheap one you cannot. Set both against the wider field on the Heathrow hotel guide before you commit.
