Layover in London: An Expert Guide to Scheduling Your Stopover

London Heathrow Airport (LHR) is the largest international airport in the United Kingdom and one of the busiest aviation hubs in the world. Located about 24 kilometres (15 miles) west of Central London, Heathrow handles more than 78 million passengers a year and serves over 200 destinations across six continents.

If you have a layover in London, Heathrow offers plenty to do both inside the terminals and in the city itself if you have enough time. In this guide, we’ll show you how to use every hour wisely and share practical tips for a smooth London airport layover — from dining and shopping in the terminals to quick trips into Central London.

London Transit Visa Requirements

The first question when planning a layover in London is whether you need a transit visa. Your requirements depend on your passport, whether you plan to stay airside or pass through UK border control, and the length of your stop.

Travellers who remain airside and hold a confirmed onward ticket may be eligible to transit without a visa as long as their connection is within 24 hours and they do not go through immigration. Nationals of certain countries—such as Afghanistan, Iran, Nigeria, Pakistan —must hold a Direct Airside Transit Visa (DATV) to change planes at Heathrow even if they stay in the transit zone.

If you want to exit the airport and explore London, you may need a Visitor in Transit visa or qualify for visa‑free entry under the UK’s standard visitor rules. Citizens of the EU, EEA, United States, Canada, Australia, Japan, Singapore, and several other countries can usually enter the UK visa‑free for short stays. Visa policy can change, so always confirm your exact status on the official UK government website before you travel.

What to Do at the Airport During Your London Layover?

If your connection is under five hours, immigration lines and travel time make it risky to leave Heathrow. Luckily, the airport feels like a mini city with dining, shopping, and relaxation options to keep you busy.

In the next sections, we’ll cover the best ways to spend your time without stepping outside the terminals.

Restaurants Worth a Stop

Heathrow features an impressive food scene. In Terminal 5, Gordon Ramsay Plane Food offers British classics like fish and chips and an express menu designed for 25‑minute dining. Terminal 2 houses The Perfectionists’ Café by Heston Blumenthal, where you can grab wood‑fired pizzas and liquid‑nitrogen ice cream. If you prefer quick comfort food, Leon serves healthy wraps and breakfast pots in multiple terminals.

Best Stores to Browse Between Flights

Shopping ranges from high‑street to haute couture. Harrods – The Terminal 5 Store stocks luxury accessories and gourmet gifts, while World Duty Free carries cosmetics, spirits, and confectionery at tax‑free prices. Travellers looking for quintessentially British souvenirs can pick up fine teas at Fortnum & Mason (Terminal 5) or classic leather goods at Mulberry.

Passengers can also book spa treatments at Be Relax (T5 & T3) or squeeze in a Peloton session at the Plaza Premium Wellness Spa in Terminal 2.

How to Spend Long Layover in London?

If your layover exceeds five or six hours and you meet UK entry rules, London’s sights are within easy reach via the Heathrow Express (15 minutes to Paddington) or the Piccadilly Line (45 minutes to central stops).

8‑Hour Layover in London

Hop on the Heathrow Express to Paddington Station, then take a short taxi or Tube ride to Hyde Park for a walk around the Serpentine.

12‑Hour Layover in London

Start with the 09:00 Changing of the Guard at Buckingham Palace, then stroll down The Mall to Trafalgar Square and visit the National Gallery (free entry).

Enjoy dinner at Borough Market before returning to Heathrow.
