What we cover

Plant-room gas work, end to end.

Plant-room CP42

Tightness test on the gas train, purging procedure where applicable, combustion analysis on every appliance, ECV check, ventilation review, pipework integrity, expansion vessel pressure. Written CP42 record per plant room. Compliant with current Gas Safety (Installation and Use) Regulations.

Multi-boiler cascade systems

Cascade lead-lag controllers, sequenced firing, manifold balancing, modulating controls. We service the entire cascade as a single system rather than each boiler in isolation, so balance and modulation issues get caught.

Gas train work

Gas train inspection, regulator replacement, ECV swap, pressure-test on the meter outlet, pipework rework. Common when plant is upgraded or repurposed (school refurb, office reconfiguration, hospital ward conversion).

Multi-tenant coordination

Office buildings and serviced properties need work scheduled around tenant operations. We coordinate with the FM team or building manager: out-of-hours where required, isolation notices issued, work documented for tenant records.

FAQs

Plant-room work: what FM teams ask.

What plant room work do you do?

Multi-boiler cascade systems, gas trains, gas pressure regulation, ECV checks, pipework integrity, expansion vessels, pressurisation units, condensate routing, HW cylinders, plate heat exchangers, manifold balancing. Service, fault-finding, replacement and CP42 documentation across the plant.

Do you handle larger commercial buildings?

Yes. Office buildings, multi-tenant developments, care facilities, hospital wings, school plant rooms. Multi-tenant work is coordinated with the building manager or FM team and the work scheduled around tenant operating hours.

What does a plant-room CP42 look like?

Tightness test on the full gas train, purging procedure where applicable, combustion analysis on every appliance, ECV check, ventilation review (combustion air, dilution air), pipework integrity, expansion vessel pressure check. Written CP42 record per plant room, plus a refrigerant log entry if F-Gas applies.

How long does a plant-room visit take?

Half a day to a full day depending on the number of appliances, gas train complexity and access. Larger plant rooms (4+ boilers, multiple gas trains) typically run a full day with a return visit if any remediation is needed.

Can you do gas train upgrades or replacements?

Yes. Gas train replacement, pressure regulator upgrades, ECV swaps, pipework rework. Common when plant gets upgraded or repurposed. Quoted off a site survey, scheduled around tenant or building operations.

Plant-room CP42 or service due?

Multi-boiler cascade, gas train and ECV work. Multi-tenant FM scheduling. Gas Safe registered.
