Heathrow in numbers: How much will it cost? When will it be delivered?

After today's government announcement that it will back the creation of a third runway at Heathrow, now the attention will come down to the detail of the plans.

How much will it cost? When will it arrive? And will it pass a Commons vote? What happens next? We crunch the dates and numbers you need to know.

£17.6bn

This is how much the airports commission said the new runway would cost, but Heathrow has been asked to reduce it. It is apparently working on revised plans. Gatwick estimates its new runway would cost £7.4bn, while the Airports Commission says it would cost £9.3bn.

15

Number of months since the Davies commission officially backed Heathrow for airport expansion. Why has it taken so long?

£61bn

A new runway will provide a huge amount of economic benefit to the wider community, the government has said.

77,000

Estimated number of additional jobs building a new runway is likely to create over the next 14 years. Heathrow is also committed to creating 5,000 apprenticeships over the same period.

£2.6bn

The amount that will be spent on a compensation package for local residents. This will include community support, insulation and respite from noise. Of that, £700m is expected to be spent on noise insulation for residential properties alone.

£50,000

The Prime Minister's local council, Windsor and Maidenhead, said it will spend a lot of money to challenge the Heathrow decision. That brings the total for the four councils in the area – Hillingdon, Richmond and Wandsworth – to a whopping £200,000.

2017/18

MPs will take a vote on the airport decision in a year or so. A public consultation will be held in the meantime on the effects of airport expansion.

2025

The year it is expected that a new runway would be operational from. That's at the very earliest – and could depend on this legal challenge.

750

The number of homes it is estimated will have to be demolished to make way for the new runway. As if we weren't already short of homes…

6.5 hours

There is a suggestion from the government to put a ban on scheduled night flights for 6.5 hours at Heathrow. The timing of this will be determined through consultation.

125 per cent

People with homes subject to compulsory purchase will receive more than the market value for their homes, plus stamp duty, legal fees and moving costs, the government has said. The rise in house prices in the last year has bumped up the costs of this by millions already.
