What Heathrow’s Closure Means for Your Journey
Posted in High Risk Travel Insurance on 21 March 2025

Today’s disruption at Heathrow Airport is causing major headaches for travellers. A fire at a nearby electrical substation has led to a power outage, resulting in the temporary suspension of all flights. With the airport closed and chaos unfolding, many passengers are left stranded, with flight cancellations and delays wreaking havoc on travel plans.
If you’re travelling through Heathrow, or planning a trip, here’s everything you need to know to manage the situation.
What Happened at Heathrow?
A fire at an electrical substation in Hayes, west London, triggered a significant power outage at Heathrow Airport. The blaze knocked out power to vital parts of the airport, forcing authorities to ground all flights for the time being. British Airways, which operates a large number of flights out of Heathrow, has suspended all services until further notice.
While efforts to restore power are underway, it’s unclear when normal operations will resume, meaning the airport remains closed and thousands of travellers are left in limbo.
How Is the Closure Affecting Travellers?
As the power outage disrupts operations at one of the world’s busiest airports, here’s how the situation is impacting travellers:
- Flights Cancelled and Delayed: Many flights from Heathrow have been cancelled, and others face lengthy delays. British Airways has grounded all its flights, leaving travellers uncertain about when they’ll be able to reschedule. With operations thrown into disarray, it’s expected to take several days before things return to normal.
- Rerouted Flights: For those connecting through Heathrow, many will now face the additional stress of missing their connections. As flights are being diverted to other airports, such as Gatwick or Stansted, you may be rerouted to another location. This could result in longer travel times and even more changes to your itinerary.
What To Do if You’re Affected?
If you’re stuck in this mess, here's what you should do to stay on top of the situation:
- Stay Updated: Keep an eye on updates from your airline and Heathrow Airport. Social media is also a useful tool, with airlines like British Airways sharing the latest news. But be prepared for some delays in communication, as many passengers are in the same boat.
- Contact Your Airline: If you were meant to fly from Heathrow today, don’t head to the airport. Contact your airline to discuss rebooking options. British Airways and other airlines will be working to re-route affected passengers, but patience will be key as this is going to take time. You may also be rebooked through nearby airports, such as Gatwick or Stansted.
- Avoid Going to the Airport: If you were planning to travel to Heathrow today, hold off. The airport is closed to flights, and staff will be stretched thin. Heading there will only add to your frustration as you're unlikely to receive any assistance right now.
- Know Your Rights: hen flights are cancelled or delayed, passengers are often entitled to compensation, especially for long delays or cancellations. Check with your airline to see if you qualify for compensation or alternative arrangements.
- Consider Other Airports: If you’re desperate to get moving soon, look into flights from other London-area airports, such as Gatwick or Stansted. But bear in mind, these airports are likely to be busy, with many passengers being rerouted due to Heathrow’s closure.
Travel Insurance: How It Could Help During Disruptions
If you’re looking for compensation due to this disruption, remember to contact your airline first before seeking other solutions. Airlines are required to follow a claims process, and it’s important to go through that route first.
Once you’ve explored the compensation options available from your airline, your travel insurance could help cover any additional expenses not compensated by the airline.
Here’s how travel insurance could help you during this disruption:
- Flight Delay and Cancellation Cover: Many travel insurance policies include compensation for flight delays or cancellations, which could help you recoup costs incurred from the disruption.
- Alternative Transport Costs: If your flight is cancelled or you’re rerouted, your travel insurance might cover the costs of alternative transport. This is especially helpful if you need to quickly arrange a different way to get to your destination, whether that’s booking a train, bus, or flight from another airport.
- Trip Interruption Coverage: Disruptions like these can completely change your travel plans. If you miss connections or are delayed in reaching your destination, travel insurance could help cover the costs of rebooking your flights, accommodation, or other necessary changes to your trip.
