Booster Pump Servicing London
Same-day response across London and surrounding areas
Regular booster pump servicing is the cheapest insurance a commercial building can buy. A planned service visit catches worn seals, perished pressure vessels and drifting controls long before they become a 6am breakdown. We deliver commercial booster pump servicing in London as one-off visits or as part of a planned preventive maintenance (PPM) schedule aligned to SFG20.
Every service is documented with a full asset report — pump condition, test results and recommendations — giving facilities managers and managing agents a clear audit trail for insurers and compliance files.
What a Booster Pump Service Includes
A full service covers the mechanical, hydraulic and electrical sides of the set. Pumps are checked for seal weep, bearing noise and motor current draw; the pressure vessel is tested and re-charged to the correct pre-charge pressure; non-return and isolating valves are exercised; and the control panel, drives, transducers and dry-run protection are tested and recalibrated.
- Mechanical seals and gaskets inspected, replaced where worn
- Impellers, wear rings and bearings checked for wear
- Pressure vessel diaphragm test and pre-charge recharge
- Control panel, drives and pressure transducers tested and calibrated
- Non-return and isolating valve operation check
- Duty/standby rotation check and full system pressure test
Planned Preventive Maintenance (PPM)
For buildings with critical water supply — hotels, hospitals, residential blocks — we recommend a structured PPM programme with six-monthly or annual visits. PPM clients receive priority response on breakdowns, a fixed annual price, and a single report covering every pump asset on site.
Servicing intervals are set by duty: heavily used sets on tall buildings typically need six-monthly attention, while lightly loaded sets can be serviced annually.
Same-Day Service Visits
Need a service carried out quickly — for an insurance renewal, a new maintenance contract handover, or a pre-survey inspection? We offer same-day booster pump service visits across London and surrounding areas, carried out by experienced pump engineers, not subcontractors.

Quick Answers
The questions people ask Google most often, with straight answers from our engineers.
- How often should a booster pump be serviced?
- At least once a year. Busy commercial buildings, hospitals and hotels usually have servicing every six months, in line with SFG20 schedules. A service covers pressures, motor currents, seals, vessel pre-charge, controls and alarms, and ends with a written report. Pump maintenance contracts
- How often should a booster pump run?
- A healthy booster set only runs while water is being drawn, then stops once pressure is reached. If it starts every few seconds with no taps open, or never stops, there is usually a leak, a failed non-return valve, a flat pressure vessel or a faulty pressure sensor. Booster pump fault finding
- What is on a booster pump maintenance checklist?
- Check suction and discharge pressures, cut-in and cut-out points, vessel pre-charge, motor currents, seals for leaks, bearings for noise, non-return valves, dry-run protection, break tank level controls, alarms and BMS signals. Then record everything in a written service report. Booster set maintenance
