Oktra Case Study - Billi Uk


Billi Taps to complete the stylish new office in High Holborn.

When Oktra, the London-based leading office fit out, interior design and project management company relocated to new offices, they called on Billi to make a proposal for a boiling and chilled filtered drinking water supply for their new tea point.

Challenge – high capacity at a competitive price

They asked for a tap that would have enough capacity to handle peak times of high demand, and at a competitive price. Accompanying this, the system had to be reliable, be space efficient and energy efficient too. They wanted a company that could supply the required level of customer service, both before and after installation.

The team at Billi got to work and came up with a proposal of a Quadra Plus system which would meet all the requirements that Oktra had stipulated.

  • Performance
  • Capacity
  • High Quality


Oktra have chosen a stylish matt black XL twin lever tap for the boiling and chilled function and a gooseneck matt black tap to supply hot water to the sink. Both of these functions were to be supplied by the patented under counter boiler unit which was selected because of its ability to harvest and re-use waste heat.



NO ventilation needed

As an additional benefit, this system could be installed without ventilation, and even fit into a 500mm cupboard.


“Billi were highly professional and very knowledgeable. The product is of very high quality. Furthermore, it met the needs that Oktra had in their facility and at a reasonable cost. Thank you again for the works you carried out at the new office. I can say that we are very happy and proud of the new office you helped us create and we look forward to working with you on many more projects going forward!”
