A 1,000-pupil secondary free school is set to be opened in Addington by one of the country's top education providers.

But Wallington County Grammar School (WCGS) could face opposition to the plans over concerns about road safety.

 The school, a selective boys school in neighbouring Sutton which achieved the tenth best GCSE results in the country last year, hopes to open the new school in Pioneer Place, off Featherbed Lane, in 2017.

The site is currently a place of worship for Jehovah's Witnesses and was previously home to Greenfield School.

WCGS announced plans to open a second school in the south of Croydon last year and secured Department for Education funding in March. 

No formal plans have been submitted yet but details of the location emerged this in papers to Croydon Council's children and young people scrutiny sub-committee.

The council hopes the secondary, which will have six forms of entry as well as a sixth-form, will absorb some of the pressure of Croydon's growing school-age population. 

The number of children starting school each year in Croydon is expected to have risen by 570 by 2017.

Jonathan Wilden, WCGS headteacher, said: "We are talking to Croydon because there is a worse issue regarding school places there than in Sutton.

"Educationally, WCGS is one of the best grammar schools around and we have the know-how to make a fantastic comprehensive school."

However, Heathfield councillor Jason Cummings said he would have "significant concerns" about the proposed location, at a narrow "pinch point" in Featherbed Lane.

He said: "I think the particularly branch of educational facility is something that Croydon needs and is something that a lot of constituents have been asking for, but I still need to be convinced about that site.

"I do have concerns in regard to accessibility and road safety.

"There has been significant local concern around safety at that point, as there is a significant number of large industrial vehicles that go up and down Featherbed Lane going out to the waste transfer station at Pear Tree Farm."

The school's planned site is a currently a base for Jehovah's Witnesses 

A site has also been earmarked for Croydon's first Hindu faith school, which is expected to open in September 2016.

Avanti Trust will sponsor a non-selective primary school, with two classes in each year, at Victoria House in Croydon.

A primary free school sponsored by Ark academy trust had been planned to open there, but the site was deemed two small.

Avanti's curriculum will include meditation and yoga.
