Orange has revealed the first locations for its new store roll out, adding 60 new outlets being added before Christmas and 100 over the next 12 months.
The network will also refurbish 100 stores in the next year.
New Orange stores are set to open in Southampton, Bristol’s Cabot Circus, London, Belfast, Edinburgh, Livingstone and Portsmouth.
Stores set for refurbishment (as pictured) include Derby, Manchester’s Trafford Park, Brighton, Dudley’s Merry Hill and Birmingham’s Bullring.
The stores will be built on the model of its Cardiff flagship store, which opened in October.
Orange hailed the new store as "future proof" due to features such as seated customer service booths and demo stations.
The network said it had targeted "prime retail locations" for its new stores, which would offer "innovation and technology for the 21st Century customer".
The new stores will add to Orange’s existing 338 outlets.
The layouts will include private consultation areas for customers, as well as phones for calling customer services for free.
Orange has also started its trial of new ‘customer service hubs’ so staff can resolve customer issues in-store.
Orange UK retail director Sian Doyle said: "We are already seeing the benefit our refurbishment programme has on customer sales and that is why it is fundamental that all our stores, new and old, reflect the needs of the 21st century customer."
