In 1983, recognising the need to expand their operations, the business moved to a larger location in central London and began specialising exclusively in brass door, window, and cabinet ironmongery.

Allied Hardware rebranded as A & H Brass and opened a new showroom on Edgware Road in central London, where the business continues to be operated by the original founders to this day.

A & H Brass stock lines expanded significantly, offering products in additional finishes like polished chrome and satin chrome, necessitating more space to accommodate the inventory.

The introduction of lighting products complemented the existing lines, including bathroom accessories and electrical switches and sockets.

In 2005, a significant catalogue was launched, featuring additional finishes such as antique brass and bronze, reflecting evolving consumer preferences. This release was one of ten catalogues produced.

A new website was developed during the lockdown period and launched in February 2021, demonstrating a commitment to continual improvement by expanding product offerings and finishes.
