The enterprise started with just one small shop at 33 Minster Street. John Heelas, who already had a shop in Wokingham, set up the new business in 1854 with his sons, John and Daniel. They described themselves as 'Linen and Woollen Drapers, Silk Mercers etc..' Over the years they acquired adjacent properties and by 1877, the small shop had become a fully-fledged department store.
In 1897 the family firm became a public company, Heelas Sons and Co. Ltd, and in 1890 the House of Heelas was appointed Linen Drapers and House Furnishers to HRH the Prince of Wales, a Warrant which was continued on his accession to the throne.
