Planned Maintenance

Planned maintenance is the discipline of servicing building systems on a scheduled basis, rather than waiting for something to fail. It covers the routine inspection, testing, cleaning and adjustment of mechanical, electrical and life safety plant, carried out at intervals set by manufacturer guidance, statutory requirement, or established industry practice. The underlying logic is straightforward: regular attention catches wear and minor faults before they develop into breakdowns, extends the working life of plant, and keeps a building operating efficiently and safely.

A well-structured planned maintenance programme is built around a schedule of tasks mapped to each piece of plant and system, often informed by recognised maintenance frameworks that set out recommended frequencies for different types of equipment. This schedule then drives a programme of site visits and works, supported by clear records of what has been inspected, what was found, and what action was taken.

The scope of planned maintenance is broad, spanning mechanical plant such as boilers, chillers and air handling units, electrical systems and distribution equipment, and life safety systems including fire alarms, emergency lighting and fixed firefighting equipment. Each of these has its own servicing requirements and statutory inspection obligations, and a coherent maintenance programme needs to bring them together into a single, manageable schedule.

Beyond compliance, planned maintenance has a direct bearing on a building's running costs and reliability. Plant that is regularly serviced tends to operate more efficiently, fail less often, and last longer, which in turn reduces both energy consumption and the likelihood of costly reactive repairs.
