Adlington new town would face 'severe' aircraft noise exposure.

Analysis by My Flight Path has seen the proposed development of 14,000-plus houses receive a 'Flight Blight Rating' of 22 out of 100.

This means that properties on this site are ranked in the worst 22% for aviation impact in the country.

It is suggested residents would experience aircraft noise of 77 dBA, equivalent to standing beside a washing machine.

Jono Oates, co-founder of property technology company My Flight Path, said: "Adlington's location places it directly beneath active flight paths.

"At 77 dBA, aircraft noise is comparable to a washing machine spin cycle running - audible enough to interrupt outdoor conversations, disrupt garden activities, and potentially disturb sleep during early morning and late evening flight operations.

"This isn't about stopping development but while planners focus on transport links, schools and ground infrastructure, aircraft noise exposure has received minimal attention in public consultations or environmental assessments.

"The proposal has already generated fierce opposition from local councils and residents on grounds including Green Belt destruction and inadequate infrastructure - aircraft noise adds another critical dimension to these concerns."

My Flight Path's analysis has found that 11 of the 12 recommended New Town locations will be significantly affected by aircraft noise.

According to their research, property values decrease by 0.5% to 0.6% for every decibel of aircraft noise above ambient levels of 40-45 dBA.

Based on the planned development of 14,000 to 20,000 homes and typical new-build prices in Cheshire East of £350,000-£400,000, My Flight Path estimates the total property value at risk at Adlington at £1.01 to £1.3 billion.

For individual homebuyers, this translates to losses of £63,000 to £75,600 per property.

Jono added: "The Government's Strategic Environmental Assessment must address this critical public health issue before final site decisions are made this Spring.

"Alternative locations exist that would deliver the same economic benefits without condemning families to a lifetime under flight paths.

"This isn't nimbyism - it's evidence-based planning that puts public health first."
