For a very readable summary of the key arguments against a Heathrow 3rd runway, see

Reality Check: Why politicians should reject the third runway. Excellent 2 page summary by Sally Cairns and Carey Newson

For a masterful summary (2 pages with all references) of the reasons why the UK government should not be persuaded into allowing a 3rd Heathrow runway, see this briefing by Sally Cairns and Carey Newson, from Transport for Quality of Life. They sum up all the ways in which the business case for the runway is flawed and the environmental case rests on hugely optimistic assumptions. They list these as: “planes will get cleaner and quieter at a faster rate than has previously been expected; cars and vans will also get dramatically cleaner; freight movements will somehow be optimised; the latest National Air Quality Plan will deliver all anticipated air quality improvements; the fledgling international aviation carbon offsetting scheme will generate a high enough carbon price; the national Aviation Strategy (not yet written) will come up with cost-effective mechanisms for constraining aviation emissions further; the new Independent Commission on Civil Aviation Noise will prove effective; a review of airspace (that has not taken place for over 40 years, as it is so controversial) will take place soon; HS2, Crossrail and the Piccadilly line upgrades will attract air passengers and airport staff in sufficiently large numbers; funding will be found for Western and Southern rail access; etc. It seems very unlikely that all of these will fall into place.”

The proposed timeline for a 3rd Heathrow runway


The process started with a draft Airports National Policy Statement (NPS) published early in 2017 – followed by a 16 week consultation on the draft NPS and associated documents.

The NPS then went to the Transport Select Committee, which made its report in March. http://www.airportwatch.org.uk/2018/03/transport-committee-demands-serious-changes-to-governments-heathrow-case-before-any-vote-in-parliament/


The Select Committee made its report and recommendations to Parliament.  The DfT will also review all the consultation responses and write a report of its recommendation.  The NPS and its supporting documents will be amended and updated by the DfT, taking account of the consultation responses and the Parliamentary scrutiny process.

Perhaps by summer 2018 (originally intended to be by autumn 2017) the Government places the final NPS before Parliament. There will be a debate in the Commons, and it will also be debated in the Lords. There is then a vote to approve the final within 21 sitting days.

If the final NPS is not approved by the Commons, the Secretary of State could make changes and lay a new NPS before Parliament, on which again a vote to approve would take place 21 sitting days later.  Once voted through, the NPS is then deemed to be “designated” (ie. comes into force) by the Transport Secretary.

Any Judicial Reviews would follow within a six-week period after the approval of the final NPS, but these could also occur at any point if the correct process was not followed.  Legal challenges could hold up proceedings.  There could be legal challenges at various stages, which might hold things up.

That might, at the earliest, be around the start of 2018. Once the NPS is agreed, then Heathrow can begin the formal process of seeking planning permission, which includes further consultation with local communities.

As the runway is considered to be a Nationally Significant Infrastructure Project (NSIP) through the Planning Act 2008, Heathrow would then submit a development consent order (DCO) to the planning inspectorate. (It is not a normal planning application, via the local authority – but it is considered in relation to the NPS).  Heathrow would probably also have to do some pre-application consultation events, before the DCO stage – perhaps summer or autumn 2017. There would then be a planning inquiry and examination (taking at most six months).

Heathrow will also be required to complete a number of environmental assessments to support its application for development consent. These include an Environmental Impact Assessment, an Environmental Statement, a Statement on Compliance with the Habitats Directive and a Flood Risk Assessment.

The planning inspector then submits his report to the Secretary of State (within three months);  and the Secretary of State considers the report and announces a decision (within 3 months). This would, at the earliest, be around the end of 2018.

The DfT expects the runway planning process to take perhaps 3 years, 2018 – 2021 or 2022. There will be a General Election by May 2020, in the middle of this. The DfT hope the runway would be operational by some time after 2025 or the late 2020s.

** NEW **  Short briefing.   Key fact and figures about Heathrow 

“Key Facts & Figures – Heathrow

Government decides on new runway at Heathrow – with no certainty on air pollution, noise or CO2

The government has made its announcement that it backs a 3rd runway at Heathrow, using the north west option (not the extended northern runway). It has decided to entirely follow the recommendation of the Airports Commission, by backing one runway only. The statement from Chris Grayling is on the DfT website, with a list of supporting documents. The government glosses over details of how it could ensure the runway did not cause worse air pollution, or worse noise, or higher CO2 emissions. Neither the DfT statement, nor Chris Grayling’s contributions in the House, give any clarity or reassurances on most of the problems that a 3rd runway will create.

Chris Grayling announced the government’s backing for Heathrow in Parliament. The Hansard version of the statement and questions in the Commons is at  https://hansard.parliament.uk/commons/2016-10-25/debates/4D74A7CB-8921-48BD-9960-FD15D5D1EEDF/AirportCapacity

Letter from Hounslow Council to Airports Commission July 2014

Current situation

There is now, once again, the worrying prospect of a new runway possibly being built at Heathrow, some time before 2030. Plans for a 3rd runway were rejected by the Conservative – Liberal Democrat coalition government in 2010.  BAA also then announced that it was scrapping plans for a 3rd runway.  But not for long. Earlier the Labour Government had announced in January 2009 that they would allow a 3rd runway at Heathrow.

The Conservative party, and the Coalition government in 2010 made a commitment that clearly said: No ifs. No buts. No 3rd runway.” But bowing to pressure from the aviation industry and its lobby, it decided to hand the decision of what to do about a 3rd runway to an “independent” body, the Airports Commission (with DfT secretariat), to report finally in 2015, a month or two after the May 2015 general election. The Commission produced its interim report in December 2013, with two options for a 3rd Heathrow runway short-listed.

The airport is now likely (January 2014) to hold a local consultation on which of the two options (a North-West runway destroying Harmondsworth and Sipson, or the northern option by “Heathrow Hub”) the residents of the area “prefer”. The Commission will require both submissions to be fleshed out in detail and submitted by 9th May 2014. They may be published then, or not till later. Then after October 2014, the Airports Commission is due to hold a public consultation, on the detailed schemes, lasting perhaps till December 2014. Its final recommendation to the government of the day would be made in summer 2015. None of the parties has committed itself to accepting the Commission’s recommendation.

More on the saga of the Heathrow Third Runway

Heathrow is one of the world’s busiest airports, handling more than 70 million passengers in 2012.  It handles the most international passengers of any airport (some US airports handle more, but largely domestic) though it is likely to be overtaken before long by Dubai. More than a third transfer onto other flights, making it a busy hub airport. Those transfer passengers using Heathrow to change flights have helped create a large route network. Heathrow is close to full capacity on ATMs (not on terminal capacity). Some 725,000 already live under the flight paths, within the 55 DBA Lden noise contour, and suffer aircraft noise. There were around 475,000 flights using Heathrow in 2012.

Airports Commission Interim Report


The Airports Commission’s Interim Report, in December 2013, short-listed two Heathrow options for a 3rd runway. One is from Heathrow airport itself, (its North-West option) and the other the northern option from a group called “Heathrow Hub.”  Maps illustrating the proposals below.

Airports Commission: interim report  (228 pages) 


Heathrow Airport’s own 3rd runway option, being considered by Airports Commission

Heathrow  has now been short-listed by the Airports Commission for a new runway (December 2013).

Heathrow submitted their proposal for 3rd runway (and eventually a 4th, to the Airports Commission in July 2013.  The short version can be seen at

A New Approach – summary document  

and the full details are on the Heathrow website. They say:

“Heathrow’s submission of options for additional capacity to the Airports Commission is available in full here. This is the full submission document, which was submitted to the Commission in July 2013 and contains all technical information available at this stage regarding the proposals.

Included in this document are details of our proposals for additional capacity to the North West of Heathrow Airport, which has been short-listed for further consideration by the Airports Commission and will now be examined in more detail.

Following the Airports Commission’s interim report in December 2013, we will be working closely with local residents as options are developed in more detail during the next stage of the Airports Commission process.”

North-Western option

North-Western option – potential optimisation  (ie runway very slightly further south, leaving the heart of Harmondsworth, the church, the ancient and wonderful Tithe barn within a few yards of the edge of the runway)

South-Western option  (not short-listed by the Commission)

Northern option  (not short-listed by the Commission)


An option – not from the airport itself – put forward by a company called “Heathrow Hub” is for an extension to the west of the current northern runway. Details below.

The “Heathrow Hub” 3rd runway proposal, short-listed by the Airports Commission

Their plans can be seen at http://www.heathrowhub.com/

The Airports Commission, in December 2013 in their Interim Report, short-listed the northern option (not the whole proposal).

Their full submission is at http://www.heathrowhub.com/media/download_pdf/Report_190713_Rev_A.pdf

It would look something like this:

Heathrow hub northern runway

The southern option would have meant building a runway over the Wraysbury reservoir, with all the attendant problems.



Heathrow’s plans for a 4th runway

Heathrow Airport’s July 2013 submission to the Airports Commission sets out its plans for, eventually though not in the short term, a 4th runway.  Options 1 and 2 require building over reservoirs. Option 3 involved building the runway over the M4 to the north.

Heathrow fourth runway options

Among  other comments in the Heathrow proposal, on the 4th runway, Heathrow says:

“Our initial analysis shows that it would be possible to have four runways at Heathrow, while still reducing the total number of people within Heathrow’s noise footprint compared to today. We estimate the cost of developing a fourth runway at Heathrow at an additional £8-14 billion depending on the option. Developing from a three-runway to a four-runway Heathrow would require the compulsory purchase of 850-950 additional properties under the North-West/South-West option, 850-2,700 additional properties under the North/South-West option or 200 additional properties under the dual North-West option.”


They also say, of the 4th runway:

“As an example of this further optimisation, we are already investigating a revised
version of our North-West option which moves the new runway further south to
its minimum spacing. This serves a double purpose – to allow the potential future
addition of a fourth runway in the north-west and to minimise the impact of a third
runway in that area. Initial analysis shows that this new third runway location will
preserve the most important heritage sites in Harmondsworth – St. Mary’s Church
and its cemetery, the Tithe Barn and the village green and its surrounding properties
and have considerably less residential property impact (600 as opposed to 950
properties). It would also avoid the need to rebuild the M4 / M25 junction. We intend
to continue to explore this variation, which we have included in Appendix A, with our
other option plans (entitled 3R North-West: Potential Optimisation) and will share this
information as it emerges if requested to do so by the Commission.”

BAA Heathrow Operational Freedoms Trials

November 2011 to March 2012 and during the Olympics

People living under Heathrow flight paths faced increased noise after the introduction of new runway rules. BAA has trialled a scheme allowing the use of both runways simultaneously from July to Sept 2012. Currently, those living under the flight path have a respite from noise when the runways alternate at 3pm. Under the trial, which will also run from November 2012 to February 2013, the threshold for triggering emergency dual use of the runways will be lowered.  Residents could face increased noise from losing some of their respite periods.   More details …..

On 1st November 2012, BAA  (now called Heathrow Airport) announced that two parts of the trails will not take place (Phase 2, Operational Freedoms 2 and 3 – about delaying flights from 4.30 to 5.00am in exchange for more flights from 5.30am to 6am; and re-directing departing aircraft from their route sooner after take-off).  More details ….

Night Flights

The existing night flight regime concerning night flights at Heathrow, Gatwick and Stansted was due to be replaced.  However, the decision was taken in November 2013 to delay any changes to 2017.
There are around 16 landings per night at Heathrow, and normally these arrive between 4:30 am and 6:00 am.  Opponents of night flights want there to be no night flights between 11:00 pm and 6:30 am as these breach  human rights, they are a net drain on the UK’s economy
The night period is the 8 hour period from 2300 to 0700 local time, and the night quota period is the 6.5 hour period from 2330 to 0600 local time. The hours of the night period before and after the night quota period (2300-2330 and 0600-0700) are commonly known as the shoulder period. Separate quotas are set for both the summer and winter seasons which change with the clocks.During the night period, the noisiest aircraft (as defined by Quota Count (QC) classification) may not be scheduled to land or take off. During the night quota period, aircraft movements are restricted by numerical movement limits and also by noise quotas which are set for each summer and winter season.See Structure of the Current Night Flights regime


Government to make no significant change to night flights regime at Heathrow, Gatwick and Stansted until Airports Commission report

11.11.2013In January 2013 the DfT put out the first part of its consultation on the night flight regime at the UK’s 3 designated airports, Heathrow, Gatwick and Stansted. The DfT said then that the 2nd consultation would be published later this year, to include specific proposals for the new regime, such as the number of permitted night flights – informed by the evidence from the first consultation. The DfT has now published this 2nd stage, but instead of any specific measures, it proposes no significant change to the night flight regime at Heathrow until 2017. It says it does not want to pre-empt the findings of the Airports Commission which is due to publish its final report in summer 2015. It gives the impression of passing the buck to Sir Howard Davies. The current night flight regime for the 3 airports ends in October 2014. Normally a new regime is put in place to cover the next 5 – 6 years. This time the Government has decided in effect to roll-over the existing regime until 2017. The only change for Heathrow is a proposal “to extend the operational ban on the noisiest types of aircraft to include an extra half hour, the 23.00-23.30 period. http://www.airportwatch.org.uk/?p=18310
