Pumps, Pressurisation and Plant
Repair and replacement of pumps, pressurisation units, valves and plant room equipment.
Gas Safe and Refcom registered
Planned and reactive maintenance
What’s included
Done once. Done right.
Pump repair and replacement
Pressurisation units and vessels
Valve and strainer works
Plant room upgrades
Plant rooms keep heating and water systems running. We service and replace circulating pumps, booster sets, pressurisation units, expansion vessels, valves and controls, and plan plant upgrades that cut running costs and reduce failures.
Plant room equipment kept running
Behind every heating and water system is a plant room full of pumps, pressurisation units, expansion vessels, valves and strainers. When one fails the whole system stops, so we service and replace them before that happens and respond quickly when it does.
We work with Grundfos, Wilo, Lowara, Armstrong, DAB and Xylem pumps, Mikrofill, Flamco and Reflex pressurisation units, and Spirotech and Elysator dirt and air separators. Like-for-like replacements are usually held in stock or available next day, and we can specify upgrades that cut running costs where older fixed-speed pumps are still in service.
What we look after
Circulating and booster pump service and replacement
Pressurisation units, expansion vessels and fill loops
Isolation, control and safety valves
Strainers, dirt separators and system water quality
Plant room pipework and insulation repairs
Plant room upgrades and energy-efficient pump replacements
Reactive, planned or upgrade
A failed pump is a reactive call that our helpdesk handles the same day. Pumps and pressurisation units on a PPM schedule are checked at every heating service, with pressures, run hours and condition recorded in Simpro. Where a plant room is tired, our project team can replace plant in phases so the building keeps running, acting as principal contractor if the job needs it.
We maintain plant rooms across London, the South East, East Anglia and the Midlands for FM companies and building owners.

Why it matters
The right engineer.
First time.
01
Plant that stays pressurised
A failed pressurisation unit or booster set takes the heating or water down with it. We service, repair and replace the plant that keeps systems running quietly in the background.
02
One point of contact
Our helpdesk logs every job in Simpro, so you always know who is attending and when.
03
Every job documented
Photos, job sheets and certificates are sent on completion for your compliance records.
