The supermarket chain told Hillingdon is Here 45 new jobs had been created as a result.
The Lidl, which is situated on Victoria Road, will open at 8am, containing a 1,687m² sales area, an in-store bakery, longer style tills with dual packing, customer toilets, baby changing as well as parking for both cars and bicycles.
The German retailer has created the new shop on the former Rover and Comet site, located on the south side of Victoria Road at the junction with Stonefield Way and next to South Ruislip Retail Park.
There is already fierce competition among supermarkets in the area, with Aldi and ASDA both opening new stores close by only last year. Aldi also opened on Victoria Road, while ASDA has been built on Old Dairy Lane. They join the existing Sainsbury's superstore also on Victoria Road/Long Drive.
The new Lidl will be open from 8am to 10pm from Monday to Saturday, and on Sunday from 10am to 5pm.
Lidl UK’s Regional Head of Property, Shane O'Farrell, said the company can not wait to get up and running. He said: “We would like to thank all those who have played a part in bringing this new Lidl store to South Ruislip. It is great for us to be able to create more jobs and investment opportunities in the area.”
Councillor Douglas Mills, Cabinet Member for Community, Commerce and Regeneration at Hillingdon Council, is anticipating more investment in South Ruislip in the near future.
Cllr Mills said: "We welcome Lidl and wish them every success with their new store. After the major redevelopment of the former dairy site, it is fantastic to see more new businesses moving in, providing facilities and jobs for local people. Investors are clearly recognising the potential of South Ruislip and we expect more investment in the near future."
In April 2014, the supermarket chain’s bid to build a new store was rejected by Hillingdon Borough Council, despite public backing, according to the company. The council planning committee then approved an application in 2015.
Lidl set up a website promoting the plans to attract support from residents in the area, with its reasons to support the application including up to 30 new jobs for people living nearby.
The supermarket firm said at the time: “The introduction of a discount food retailer to South Ruislip will improve choice and promote competition.
“The proposed development will regenerate a key brownfield site that has been vacant for a significant number of years and is in a poor state of repair.”
Many new shops have sprung up in South Ruislip in the last year or so, including B&M as part of a wide scale regeneration.
A new Cineworld Cinema and restaurants such as Nando’s, Frankie and Bennies and Chiquito also opened in South Ruislip last year, as part of the Old Dairy redevelopment on Victoria Road.
