Politicians representing wards blighted by aircraft noise are demanding free double glazing for all if Heathrow gets an extra runway.

Councillor Jim Maddan, Councillor Rosemary Torrington and Councillor Mike Ryder have written to the Transport Secretary requesting the glazing for people living in Thamesfield ward.

People living in the area, which covers the Riverside Quarter to Putney High Street, are expected to be disrupted by more early morning flights if the third runway is given the go-ahead.

The Davies Commission preliminary report published last month revealed a new runway was the preferred option for airport expansion.

Options of a third runway at Heathrow, lengthening an existing runway at Heathrow or a new runway at Gatwick with an estuary airport in Kent will be considered at a later date.

The letter states: "Residents in our area already suffer considerably from the noise of planes going over their houses as early as 4am every day, which shatters their sleep and is a real health hazard.

"If Heathrow does operate more night and early morning flights, which will increase the profits of the airport’s operators, we believe you should demand that Heathrow pays for affected residents in Putney to have free secondary glazing in their homes to prevent noise and protect their sleep and their health."

Coun Torrington, of Deodar Road Putney, has regularly campaigned on the issue as she is regularly affected by aircraft noise.

Over Christmas she was woken by a plane flying over her house at 11.40pm on December 23 and another on Christmas Eve just before 4am.

She said: "Morning after morning I get woken up as early as 4am by planes, and it’s impossible to get back to sleep again.

"This really is affecting people’s health, and it’s totally unacceptable environmentally as well.

"These early-morning flights are just operated to increase Heathrow’s profits, at the expense of Putney residents’ health and the enjoyment of their homes. Mr McLoughlin really does need to do something."

A spokesman for the Department of Transport said: "We are aware of the correspondence and will respond in due course."
