Richer Sounds has recorded the biggest operating profit in its history

Operating profits increased by 14% from £6.9m to £7.8m during the 52 weeks to May 3 as like-for-like sales increased by 0.9%.

All the business’s 52 stores and one franchise store in Northern Ireland traded profitably after deducting trading expenses including interest, distribution and advertising.

The electricals retailer is renowned for its stores having the highest trading densities in the country and its London Bridge store holds the Guinness World Record for having the highest turnover per sq ft of any store in the world.

The company is built on slow expansion and fostering a solid culture under the guidance of founder Julian Richer, who owns 100% of the company.

Richer has formed a trust for when he dies that will bequeath the entire business to employees through the formation of a John Lewis-like mutual.

The company has stated in its latest results that its strategy continues to be to consolidate its position through working hard at giving its customers value for money and a service second to none and looking after its employees.
