Reliable and efficient modern plant room saves energy for FM client


Boiler Replacement and Plantroom Upgrades at Capita House and Capita Park, Rotherham.


Capita is the UKs leading provider of outsourced customer management services, making processes smarter, organisations more efficient and customer experiences better.

Two plant rooms with ageing and inefficient boilers provided heating to two separate call rooms, each of which has circa 1500 occupants.


Ellesmere was commissioned by Mitie to replace half of the ageing and inefficient heating boilers in each plant room with new high efficiency boilers. The remaining half were serviced and repaired. Along with the associated new flue dilution systems and pipework modifications, Ellesmere has replaced all the existing pumps in both plantrooms with new energy efficient pumps.
