Nisa is rapidly revamping its entire estate, with the first 50 new-look stores due for completion by the end of this month, the company has announced.

A further 50 stores will be transformed into a Nisa ‘Store of the Future 2’ format by next April and all other stores will be updated within three years.

The roll-out of the new format has been driven by “average double-digit sales growth” at all stores converted so far, with new and existing Nisa members “keen to adopt” the new concept, said Nisa format and development director Raj Krishan.

“The concept goes back to retailing fundamentals really – giving the customer what they want, where and when they want it,” said Krishan.

“In a challenging market, this kind of investment is necessary to ensure stores are fit for the future challenges and meet consumer demand, adding much needed growth.”

The ‘Store of the Future 2’ project involves splitting the estate into five categories - neighbourhood, high street, small store, forecourt and supermarket. Most of Nisa’s initial conversions have been to the neighbourhood format.

Nisa began rolling out the new store formats in September, after launching pilot stores earlier this year as a result of detailed analysis of store formats and shopper missions.
