Question to the Department for Transport:

To ask the Secretary of State for Transport, how many times noise quotas at each London airport have been breached in each of the last 10 years.

There have been no breaches of the night noise quotas in the last 10 years. For the night period (23.30 to 06.00), there is a limit on the number of movements (an aircraft landing or taking off) and noise quotas (each aircraft is given a noise quota according to the noise produced) at Heathrow, Gatwick and Stansted for the summer and winter seasons.

There are, and have been, no penalties for breaching the movement and noise quota limits. Details on these limits are set out in the London Heathrow, London Gatwick and London Stansted Airports Noise Restrictions Notices.
