Heathrow says third runway to be delayed by at least a year

Airport blames Civil Aviation Authority for denying its request to quadruple spending

Heathrow has said its controversial plan to build of a third runway will be delayed by at least a year after the aviation regulator denied its request to quadruple spending before gaining planning consent.

Heathrow had asked the Civil Aviation Authority for permission to boost spending from 650m to 2.4bn despite the fact it has not yet gained permission to expand. Heathrow said the decision not to greenlight the amount it had requested would delay a third runway being completed until between "early 2028 and late 2029".
