Early Days of the Cromwell Mint Casino London

Long before the name Cromwell Mint Casino London became synonymous with boutique gaming, the building at 45 Cromwell Road operated as the 45 Club, a stylish 1960s venue offering entertainment to affluent Kensington and Knightsbridge residents. This early identity would later inspire the 2019 rebrand.

The 45 Club’s reputation rested on exclusivity, elegant décor, and a cosmopolitan crowd. Its location opposite the Natural History Museum made it a discreet yet prestigious destination. Over time, the venue evolved, eventually becoming part of Genting Casinos UK Ltd, one of Britain’s most established gambling operators.

Rise of the Knightsbridge Casino London

By the early 2000s, the venue had become the Cromwell Mint Casino London, operated by Genting UK. It embraced the boutique casino model: intimate gaming floors, personalised service, and a refined atmosphere distinct from larger West End casinos.

The casino offered the usual casino games: American roulette, blackjack, baccarat, three‑card poker and a curated electronic gaming area

These features helped cement its reputation as a luxury casino London destination, attracting international visitors, business travellers, and Knightsbridge locals seeking privacy and sophistication.

Cromwell Road & Knightsbridge Casino Culture

The 47 Cromwell Road casino was ideally located at the heart of one of London’s most affluent districts. Surrounded by museums, luxury hotels, and embassies, the Cromwell Mint Knightsbridge thrived on a mix of local prestige and international tourism.

Visitors often described the Cromwell Mint as a high‑roller casino in London that balanced glamour with discretion, an essential quality in Knightsbridge nightlife.

Challenges & Changing Market Conditions

Despite its strong reputation, the casino industry faced increasing competition from online gaming platforms and larger integrated purpose-built gaming venues. Boutique casinos like the Cromwell Mint had to adapt to shifting consumer habits and rising operational costs. By the late 2010s, Genting UK began planning a major transformation to modernise the venue and reconnect it with its heritage.

From Cromwell Mint to Forty Five Kensington

In 2019, Genting UK announced a full refurbishment and rebrand of the Cromwell Mint Casino London, returning it to its original identity as Forty Five Kensington, a nod to the historic 45 Club.

The renovation included:

A new private gaming room
Expanded electronic gaming area
Upgraded main gaming floor
Enhanced bar and restaurant spaces
Warm lighting and modern interior design

The refurbishment was completed over 14 weeks while the casino remained operational, requiring careful planning due to restricted access and the busy South Kensington location.
