CommercialBooster Sets

Sizing comes down to two figures: the peak flow rate (litres per minute) your building needs at busiest times, and the pressure boost required to overcome height and pipe losses. As a rule of thumb, count up simultaneous outlets — taps, showers, WCs — and factor in the number of floors or the distance from source. If you're unsure, send us your outlet schedule and building layout and we'll help you match it to the right set.

A single pump set is suited to smaller applications with modest, fairly consistent demand, such as a small office or site cabin. Twin sets duplicate the pump so one can run while the other is on standby or sharing load, giving redundancy for busier premises. Triple sets are built for higher flow rates and heavier commercial demand — hotels, multi-storey offices, retail units — with pumps alternating or working in parallel to match peak usage while extending overall service life.

Yes — compact commercial sets are specifically designed with a small footprint for exactly this, fitting into plant rooms, utility cupboards or confined service areas. You'll still need adequate ventilation, access for servicing and a suitable electrical supply nearby. Check the unit's dimensions and clearance requirements against your space before ordering, and we can advise on layout if needed.

Yes, we'd always recommend installation by a competent plumbing or mechanical engineer, particularly for the electrical connections and commissioning of the pressure control system. Correct installation also matters for warranty purposes and for compliance with Water Regulations, since booster sets connect directly to the mains supply. Get in touch if you need guidance on installation requirements before you commit to a system.

Yes, we offer simpler site boost units specifically for temporary or lower-requirement applications, such as maintaining usable pressure during a build before permanent services are commissioned. These tend to be more compact and straightforward than the GRP-insulated triple sets built for permanent, high-demand commercial use. Let us know your expected duration and flow needs and we can point you to the right option.

GRP (fibreglass) insulated booster sets protect the pump and pipework from temperature extremes, which matters if the unit is sited somewhere unheated or exposed to the cold, such as an external plant room. The insulation also helps reduce condensation and noise transmission compared with an uninsulated frame. These are typically specified for larger, permanent installations where maximum flow rate and pressure reliability are essential, such as hotels or multi-storey buildings.
