About the RoyalFlow BCS Smart Tap
The RoyalFlow BCS Smart Tap gives instant boiling, chilled and sparkling water from a single touch-button tap. The tank unit sits under the sink. It holds a 3 litre boiling tank rated for 125 cups an hour and a 2.5 litre chilled tank rated for 100 cups an hour, and sparkling water is available on demand. It is a commercial-grade, NSF-rated tap, designed for offices, kitchens and hospitality venues.
RoyalFlow is Sovereign Water's own smart tap range, so we specify, supply, fit and service it ourselves. If you are weighing it against other options, see the whole RoyalFlow range to compare the models, and our comparison of an instant boiling water tap and a kettle for the wider choice.

Typical applications
Who the RoyalFlow BCS is for
- Offices and boardrooms that want boiling, chilled and sparkling water at one tap instead of a kettle, a cooler and bottled fizz.
- Corporate and institutional sites that want a clean, modern tap with a touch-button interface.
- Hospitality venues and commercial kitchens that need instant boiling water and a premium finish at the point of service.
- Sites that want an efficient unit: the controller powers it down when nobody is using it.
- Buyers who want treatment as part of the package, because the tap can be paired with a Sovereign water treatment system tailored to the local water.
How the RoyalFlow BCS Smart Tap works
The datasheet sets out the path from mains to glass in five steps: the mains feed, optional water treatment, the boiling and chilling tanks, CO₂ carbonation, and the touch-button dispense. Mains water passes through treatment if you have specified it, then fills the 3 litre boiling tank and the 2.5 litre chilled tank in the under-sink unit. Sparkling water is carbonated with CO₂ and dispensed at the touch of a button.
An efficiency controller powers the unit down during periods of inactivity. The datasheet says this optimises energy use without compromising responsiveness or performance. The unit draws 1 kW for the hot side and 0.5 kW for the cold side, so 1.5 kW in total, on AC 110/220 V at 50/60 Hz.
Treatment is optional and sold separately. The datasheet says it can be customised for regional water profiles, including reverse osmosis where required. For why treatment matters, see our guide to filtration versus treatment.
Which one should you choose?
RoyalFlow is a range, and other brands make capable taps too. Here is how we would choose between them. We settle the choice at survey, from your headcount, your space and your water.
RoyalFlow BCS Smart Tap
You want boiling, chilled and sparkling from one tap, in a smaller to mid-size commercial site, from our own range, with one point of contact for supply, fitting and service.
RoyalFlow C2 Smart Tap
The tap is for a home kitchen. The C2 is the residential model, with a hot and cold mixer for dishwashing and smaller tanks (2 L boiling, 1.5 L chilled and sparkling).
RoyalFlow CA and CSA
You do not need boiling water. The CA gives chilled and ambient, and the CSA gives chilled, sparkling and ambient, both from a 2.5 L chilled tank rated 100 cups an hour.
BRITA Extra C-Tap
You are specifying for a larger or heavily used site and want a BRITA-branded tap with its own system options. See the BRITA versus Zip comparison.
Zip HydroTap G5 Arc Plus
You want a Zip system sized by variant for larger groups. Our Zip HydroTap review covers the models.
Installation and servicing
The under-sink unit measures 230 × 435 × 395 mm, so check the cabinet before you order. The datasheet lists the scope of supply: the RoyalFlow tap, the under-sink unit with the 3 litre boiling and 2.5 litre chilled tanks, the touch-button dispense interface, the efficiency controller, and a premium tap finish that you specify on order. A Sovereign water treatment system and a Comprehensive Maintenance plan are optional extras.
The tap comes in premium finishes, including matte black and chrome, and in two spout styles, S1 and C1. We confirm the finish and spout style with you before ordering.
The unit carries a 1 year manufacturer warranty. We can add a maintenance plan so servicing is done on a schedule. The survey is chargeable and is credited back if you go ahead.

Supplied, installed and serviced across the UK
Across most of southern and eastern England, mains water is very hard. Rain filtering through chalk and limestone dissolves calcium and magnesium, and that scale coats heating elements, so we size every system to your supply and your equipment.
