The fine from the Competition and Markets Authority (CMA) is over an agreement with Arora Group for the lease of the Sofitel hotel at Heathrow’s Terminal 5.
A CMA investigation revealed there was a clause in the lease between Heathrow and Arora restricting how parking prices should be set by Arora for non-hotel guests.
The CMA said that both Heathrow and Arora had breached competition laws – a decision that has been formally accepted by both companies with Heathrow paying the £1.6 million fine.
Arora will not be fined after being granted immunity for coming forward under the CMA’s leniency programme.
