Everything Everywhere, the mobile phone retailer created by the merger of T-Mobile and Orange, will trial dual-branded stores next month in a move that could result in store closures.

The trial is planned for November, in three stores in towns in the West Country, although the retailer would not reveal the exact locations.

Everything Everywhere chief commercial officer Andrew Ralston said: “We are looking at small market towns where we have both Orange and T-Mobile stores and considering combining both. Store closures are dependent on the pilot.”

The exact design and branding of the stores has yet to be confirmed.

EBITDA at Everything Everywhere, which operates 723 shops, declined 18.5% to £309m in its second quarter.
