Surrey village to suffer a lot more Heathrow flights
Residents could suffer “an unacceptable amount of noise” from an airport as flight directions change, meaning the number of landing planes could increase from 36 to over 300 a day in a Surrey village.
Heathrow Airport is proposing to change its flight patterns to share noise more equally to communities around the site. This involves alternating between the southern and northern runways when the airport operates flights eastwards.
Most of the time (70 per cent) the airport runs on westerly operation, meaning planes take off and land towards the west as the wind favours the west direction at Heathrow. From 7am-3pm, planes land on the northern runway and depart on the southern runway. Halfway through the airport’s day, at 3pm, Heathrow switches runways to give neighbouring residents a break.
This is because of the Cranford Agreement in 1952 which restricted departures over Cranford. But the government ripped up the Cranford agreement in 2009 to bring more equal noise distribution in the residential areas around Heathrow.
As planes are now allowed to take off over Cranford (to the north-east of the airport) Heathrow is proposing to make changes to the airfield to allow for easterly operations of planes taking off and landing from the east. These include: building a noise barrier, up to seven foot high, near Longford, as well as changing the taxiways where planes turn on the runway to reduce ground noise.
The applicant states the redistribution of noise around Heathrow Airport will result in lower noise effects in some locations and higher noise effects in others, but it will enable noise from aircraft operations to be more fairly distributed around the airport than it is currently.
Despite the overall aim meant to have a more even spread of noise, Spelthorne council’s noise officer has objected to the changes as it will adversely impact Spelthorne and especially Stanwell Moor.
Currently only 36 planes arrive over Stanwell Moor on an easterly operation but if plans go ahead it could skyrocket to 328 landing a day, according to council documents. Councillor Joanne Sexton (Independent Spelthorne Group/ Ashford East), leader of Spelthorne council, said it was “quite a shock” to see the dramatic increase.
Heathrow submitted a planning proposal to Hillingdon Borough in October 2024, which is now in the consultation stage. Councillors wholeheartedly voted to object to the scheme, citing unacceptable noise impacts on the borough, at an environment and sustainability council meeting on January 14. These comments will be passed on to Spelthorne’s planning committee.
Only Cllr Paul Woodward (Conservative/ Ashford Town) approved Heathrow’s proposal, arguing: “Landing is the quietest part of the operation until you put the airbrakes halfway down the runway.”
Stanwell Moor runs directly parallel to Heathrow’s southern runway which leaves residents with a “constant stream of aircraft noise” for half the day, according to council documents. But if the airport uses full easterly alternation, the noise officer said this would “significantly increase the noise and frequency of overflights and significantly affect [Stanwell Moor] residents”.
Although Cllr Sexton raised concerns of Ashford becoming increasingly louder with plane noises, the noise officer said the changes would not harmfully impact Ashford or Sunbury.
Applauding the council for objecting to the project, Cllr Sue Doran (Labour/ Stanwell North) said: “It doesn’t matter which way [the planes] fly, the noise is terrible all the time.” Cllr Doran said she had lived in Stanwell for 15 years and said there is noise “virtually 24 hours a day”.
Heathrow Airport is aiming to introduce easterly runway alternation by 2028. Currently there is no proposed increase in the number of flights taking off or landing from the airport, just changes in the direction.
A Heathrow spokesperson said: “We know that noise is an important issue for local communities which is why we have published clear reduction targets in our Noise Action Plan. Our noise footprint has reduced by 41 per cent since 2006 and we expect to see further reductions. Easterly alternation is aimed at delivering predictable noise respite to more communities and is coupled with our ongoing work to install noise insulation for our nearest neighbours.”
