The switch will happen this spring following a £100,000 investment in the Barmulloch store.
Jeeva said: “This is an incredibly exciting next step for us.
“We’ve had a fantastic journey so far and are incredibly proud of what the store has achieved.
“The move to Costcutter allows us to strengthen our fresh and chilled offer and take the business to the next level.”
Jamie Davison, retail director at Bestway, said: “We’re absolutely delighted to welcome Girish to the Costcutter family.
“He is one of Scotland’s most entrepreneurial and forward-thinking independent retailers, with an outstanding track record of growth, innovation and community engagement.
“His Barmulloch store is already performing strongly, and we’re excited to support his ambitions as he evolves the offer further under the Costcutter brand.”
The initial phase of the refit will focus entirely on the transition to Costcutter, says Bestway, including a substantial expansion of the fresh and chilled range from 12 metres to 18.5 metres to drive quality perception and footfall.
Davison said: “Phase one is centred on establishing a best-in-class Costcutter store – with a strengthened fresh offer, improved layout and enhanced customer experience.
“Girish is investing heavily in getting the fundamentals absolutely right, and we believe this will unlock significant further growth.”
As part of longer-term development plans, Jeeva is looking to introduce Bestway’s Costcutter hybrid model, which operates a specialist beers, wines and spirits store-within-a-store concept, usually under the Bargain Booze brand.
This would form phase two of the store’s development, targeted towards the end of the year.
“The hybrid format has delivered excellent results in selected locations,” said Davison.
“Girish is one of a number of Scottish retailers who are looking at adopting this exciting model as part of a phased approach.
“However, the immediate focus is firmly on delivering a standout Costcutter store for the local community.
“We’re investing significantly in the refit and look forward to unveiling the new-look Costcutter store to customers very soon.”
As well as switching brands, the store will move to 24-hour trading following completion of the refit.
