DSGi has unveiled a new look for its Dixons and PC World formats at Heathrow’s Terminal 5, which opened last week.

The electricals giant has also created a separate new-format store, Dixons + add, which has a smaller footplate and sells electronic accessories. It has higher mid-shop fixtures to ensure appropriate densities are maintained, as well as a brighter colour palette than the existing Dixons store at the airport.

DSGi has introduced a fresh look for the interior of its Dixons store, with low fixturing and high-level, subdued navigational graphics around the perimeter. The logo has also been redesigned, with the familiar outsize white-on-red letters being replaced by a smaller iteration, using a skinny font.

For its first PC World at an airport, DSGi has introduced an Apple shop-in-shop and has redesigned its interior to present a more toned-down version of what is found at UK shopping parks.

The three formats are the result of work by design consultancy Fitch.

Somerfield’s owners have put a price tag of between£2 billion and£2.5 billion on the 900-store chain, but Co-op’s provisional first-round bid is thought to have been below that. This week, a source close to Somerfield said: “It has not come up with a suitable price.” He confirmed that the Co-op’s was the only firm bid on the table.

This week, the Office of Fair Trading told Retail Week it would investigate a potential acquisition of Somerfield by Co-op.

A successful bid would increase Co-op’s grocery market share to about 8 per cent. Somerfield has a 3.6 per cent share and all the UK Co-ops combined have 4.4 per cent.

However, CACI associate director of location strategy Paul Langston believes Co-op would have to dispose of about 37 stores on competition grounds, if a bid was forthcoming.

Langston also said that Tesco could get its hands on far more Somerfield stores than most industry experts believe, based on a relative low concentration of both chains in some areas.
