Heathrow Airport: Back To Business As Usual?

Heathrow Airport is Europe's largest airport, with over 83.9 million passengers travelling through its terminals in 2024. In March 2025, a fire at the North Hyde electrical substation in Hayes caused a power outage, leading to the airport's closure and affecting around 200,000 passengers. The airport is now returning to normal operations, with investigations into the power outage underway. Transport Secretary Heidi Alexander acknowledged the swift response from Heathrow, National Grid, and emergency services in restoring travel, but advised travellers to expect some disruption over the following days.

Delays and cancellations

Weather conditions, such as heavy snow, fog, and wind, are common causes of delays and cancellations at Heathrow. For instance, planes cannot take off or land when there is snow on the ground, and strong winds can impact a plane's ability to maintain speed and affect the safety of taking off and landing. While Heathrow has efficient teams in place to manage disruptions, a delay of just a few hours can quickly lead to a substantial backlog of flights.

Technical issues and power outages can also cause significant disruptions. In March 2025, a fire at an electrical substation near the airport resulted in a power outage, causing the airport to shut down and stranding approximately 200,000 passengers. Such incidents can lead to cancellations and delays that last for several days as the airport works to resume normal operations.

In the event of a cancelled or delayed flight, passengers have several options to consider. If the issue is weather-related or due to unforeseen circumstances, airlines typically won't cover the costs of accommodation or other arrangements. However, with comprehensive travel insurance, passengers may be able to claim back expenses incurred due to delays or cancellations. Passengers can also request that the airline re-book them on a different flight, either from the same airport or a nearby one, and in some cases, alternative modes of transport may be more feasible, such as hiring a car, taking a ferry, or using the Eurostar.

To minimise the impact of delays and cancellations, passengers are advised to stay informed through the Heathrow app, which provides live flight updates. Additionally, keeping essential documents organised and easily accessible, staying up to date with airport security measures, and being mindful of peak travel times can help ensure a smoother journey through Heathrow Airport.

Weather disruptions

Heathrow Airport is Europe's largest airport, with more than 83.9 million passengers travelling through its terminals in 2024. In March 2025, a fire at the North Hyde electrical substation in Hayes caused a power outage, leading to the airport's closure and affecting around 200,000 passengers. The airport is now returning to normal, with British Airways anticipating a 'near-full schedule' and Heathrow itself expecting to operate a "full schedule of over 1,300 flights". However, Transport Secretary Heidi Alexander warned that "some disruption is expected over [the] coming days as things get back to normal".

Heathrow Airport is no stranger to disruptions and delays. In July 2022, the airport was shut down due to a fire, causing significant travel disruptions for hundreds of thousands of passengers. Weather conditions can also cause significant disruptions at Heathrow. For example, heavy snow can lead to the closure of the airport until the runways are cleared. Larger airports like Heathrow are more susceptible to weather-related disruptions due to the high volume of flights, resulting in a substantial backlog even with efficient disruption response teams.

Rain, fog, and wind can all impact flight operations and cause delays. Fog reduces visibility, making it challenging for flight crews to navigate to the airport, and wind can hinder take-off and landing, requiring adjustments to engine power. Additionally, wind can impact flight speed and altitude, particularly when flying against strong headwinds or jet streams.

When severe weather strikes, it is crucial to follow the instructions of airport officials and stay informed about the status of your flight. If your flight is delayed or cancelled due to weather conditions, remember that it is for your safety. Keep yourself updated with the latest weather warnings and remain patient as the airport works to clear any disruptions.

To minimise the impact of weather disruptions on your travel plans, consider the following:

• Keep yourself informed about the weather conditions at your departure and arrival airports.
• Allow for extra time at the airport during peak travel seasons or periods of unstable weather.
• Have a backup plan in case of delays or cancellations, such as alternative travel arrangements or flexible accommodation options.
• Ensure you have comprehensive travel insurance that covers delays or cancellations due to weather conditions.

Power outages

Heathrow Airport is returning to normal after a power outage caused by a fire at an electrical substation in Hayes. The fire broke out on Thursday, causing more than 100 people to be evacuated and leaving thousands of homes without power. The airport, which is Europe's largest, saw around 200,000 passengers affected by the closure.

An investigation into the power outage has been ordered by Energy Secretary Ed Miliband, who is working with Ofgem to formally launch the National Energy System Operator's (Neso) investigation. The Neso is expected to report its initial findings within six weeks.

Transport Secretary Heidi Alexander emphasised the importance of identifying the cause of the power failure, stating: "It's imperative we identify how this power failure happened and learn from this to ensure a vital piece of national infrastructure remains strong." She acknowledged the swift response of Heathrow, National Grid, and emergency services in restoring operations, but cautioned that some disruption could persist as the airport returns to its regular schedule.

Former transport secretary Ruth Kelly, an independent member of Heathrow's board, will undertake an internal review of the airport's crisis management plans, its response to the incident, and its operational recovery. This review aims to identify areas for improvement in Heathrow's future resilience.

British Airways anticipated running a "near-full schedule" on Sunday, with the airport expecting to operate a "full schedule of over 1,300 flights."

Transport to the airport

Heathrow Airport offers a range of transport options for passengers travelling to and from the airport. The airport is located west of central London and is easily accessible by train, Tube, taxi, coach, or local bus. Here are some detailed transport options:

Train

The Heathrow Express train is the fastest way to travel between Heathrow Airport and central London. The journey to London Paddington takes approximately 15 to 20 minutes, with trains running from 5:20 am until midnight. The Elizabeth line also operates from Heathrow Terminals 2, 3, and 5 to major central London stations.

Tube

The London Underground (Tube) is another option for travelling to and from Heathrow. It is recommended to purchase a Visitor Oyster Card in advance for easier journeys. This card can be used for payment on the Heathrow Express and other Tube services. If you do not have a Visitor Oyster Card, you can use contactless payment cards, mobile payments, or purchase an Oyster card at Heathrow Airport's Tube stations.

Taxi

Heathrow Airport has a range of taxi and private chauffeur services available, such as HeathrowShuttle, which offers door-to-door transportation in luxury vehicles. These services can be booked in advance and provide seamless transfers to and from the airport. Taxis are also available at the airport, with queues at the designated pick-up areas. It is recommended to use only black cabs or pre-booked minicabs from reputable companies.

Coach and Bus

National Express provides frequent coach services from Heathrow's terminals and the central bus station to Victoria Coach Station. The journey time varies from 50 to 90 minutes, depending on traffic. For late-night arrivals, the N9 night bus operates from 11:45 pm to 4:45 am, running approximately every 30 minutes to Trafalgar Square in central London. Local buses, including the Hotel Hoppa, are also available for travel between Heathrow Airport hotels and the airport terminals.

Drop-off charges

Heathrow Airport has designated drop-off zones located directly outside the terminals. A charge applies to vehicles that drop off passengers at these zones. The fee is £6 per visit and must be paid online or by phone in advance, on the day of the drop-off, or by midnight the next day. This charge will increase to £6 from £5 on 1 January 2025.

It is important to note that payments cannot be made at airport ticket machines or in the terminal drop-off zones. Non-payment will result in an £80 Parking Charge Notice (PCN), reduced to £40 if paid within 14 days.

For those who wish to avoid the drop-off charge, Heathrow offers a free drop-off option at their Park & Ride car parks, previously known as Long Stay. Passengers can be dropped off here for up to 29 minutes free of charge and then take a free bus transfer to the terminal. However, please note that re-entry to the Park & Ride car park is prohibited within the following 24 hours, and this facility is not available to private hire or trade vehicles.

Blue Badge holders are also entitled to certain benefits. They can enjoy free parking for the first 2 hours in the Park & Ride car parks by providing their Blue Badge number and registration details to the operator. Additionally, blue badge holders arriving by taxi can apply for a 100% discount up to 3 months in advance, during the trip, or by midnight the next day using the taxi vehicle registration number.

For taxi and private-hire vehicle drivers, Heathrow recommends registering for a free business account. This allows drivers to set up autopay and view all their drop-offs. With a business account, drivers can also reconcile registered blue-badge drop-offs by passengers and pay anytime before their drop-off or by midnight the next day.
