Planned Maintenance: The Key to Optimising Your HVAC Assets

In the bustling world of UK’s commercial and industrial sectors, ensuring HVAC systems operate at peak performance is not just a luxury - it’s a necessity.

Planned preventative maintenance (PPM) is scheduled servicing of building plant on a defined frequency - to SFG20 in the UK - so equipment is maintained before it fails rather than repaired after. A Rossair PPM contract bundles the planned schedule, statutory compliance (F-Gas, LRA, EICR) and 24/7 reactive cover with a 4-hour emergency response, across London, Hampshire, Surrey, Sussex and Manchester.

Understanding Planned Maintenance

Planned maintenance, often referred to as preventive or scheduled maintenance, involves regular, pre-arranged checks and servicing of equipment to ensure they function optimally and to prevent potential breakdowns.

Why is Planned Maintenance Imperative for HVAC Assets?

  1. Extended Equipment Life: Regular checks and timely interventions ensure that minor issues are caught before they escalate into major problems.
  2. Enhanced Energy Efficiency: A well-maintained HVAC system runs more efficiently.
  3. Reduced Downtime: Planned maintenance drastically reduces the risk of unforeseen breakdowns, ensuring seamless operations.
  4. Safety Assurance: Faulty HVAC systems can be a health hazard, potentially releasing harmful gases or causing fires.
  5. Cost-Effective: While planned maintenance involves an upfront cost, it is often more cost-effective in the long run.

Where we run planned preventative maintenance contracts

Planned preventative maintenance in London and the M25 runs from the Aldgate office - see London building maintenance. Hampshire, Surrey, Berkshire and Sussex are covered from the Alton HQ, where Rossair has been headquartered since 1973 - see building maintenance Hampshire and air conditioning maintenance Hampshire. Manchester and the North West run from the Manchester base. The maintenance patch is deliberately tight: it is what makes the 4-hour emergency commitment deliverable.

When plant has already failed, the reactive side of the same team handles it - see commercial HVAC repair (24/7). And for the HVAC-specific service detail behind the schedule, see commercial HVAC maintenance.

In Conclusion

Planned maintenance is more than a tick-box exercise - it’s a strategic investment in the longevity, safety and efficiency of every building service asset you own. Done properly, it costs less than reactive failure, drives energy savings that often outweigh the contract fee, and produces the documented evidence trail your auditors, insurers and regulators expect to see.

Frequently asked

Planned maintenance - common questions

What is the difference between planned maintenance and reactive maintenance?
Planned maintenance is scheduled, pre-arranged servicing carried out on a defined frequency (e.g., quarterly, biannual, annual). Reactive maintenance is the response when equipment has already failed. The cost ratio is roughly 1:3-5 - planned maintenance is dramatically cheaper than reactive, and orders of magnitude cheaper than the business interruption a major failure causes. Rossair PPM contracts bundle both: planned schedule + 24/7 reactive cover.
What standard governs UK planned maintenance schedules?
SFG20, published by BESA (Building Engineering Services Association), is the de-facto UK standard for planned maintenance. It defines task lists, frequencies and grades (Statutory / Mandatory / Optional) for every building services asset. Working to SFG20 gives buyers an objective definition of what they’re paying for and gives engineers a clear schedule against every visit. Rossair contracts are SFG20-scheduled as standard.
How often should commercial HVAC equipment be planned-maintained?
Frequency varies by equipment and SFG20 task grade. Common HVAC PPM cycles: air conditioning - biannual service; ventilation - quarterly filter changes plus annual LEV TExT for industrial systems; boilers and chillers - annual major service plus quarterly checks; controls/BMS - annual review. High-use sites (24/7 operations, hospitals, data centres) typically scale frequencies up.
How does planned maintenance improve HVAC energy efficiency?
Dirty coils, clogged filters, low refrigerant charge and out-of-calibration controls collectively waste 15-30% of an HVAC system’s electricity. Planned maintenance addresses each: filter change restores airflow, coil clean restores heat transfer, F-Gas top-up restores cooling capacity, control recalibration matches output to demand. The energy savings typically outweigh the PPM contract cost on systems above 20-50 kW.
What records does planned maintenance produce?
A Rossair PPM contract produces: SFG20-scheduled visit records signed by the engineer, asset register with condition grades, F-Gas leak detection records (5-year retention), Legionella Risk Assessment (LRA) records, electrical EICR certificates, and a consolidated compliance pack delivered to the named account manager. The pack supports audits, building sales and Ofsted/CQC inspections.
Can planned maintenance be tailored to a specific budget?
Yes. SFG20 itself supports this with task grades - Statutory tasks (must do, legally required), Mandatory tasks (industry-standard, breach voids warranty), Optional tasks (best practice). Rossair scopes PPM contracts at the right grade for the building’s risk profile and budget, with clear visibility on what’s in and what’s out. The named technical lead reviews the schedule annually as assets and risk change.
Where does Rossair run PPM contracts?
PPM contracts cover London and the M25 (from the Aldgate office), Hampshire, Surrey, Berkshire and Sussex (from the Alton HQ), and Manchester and the North West (from the Manchester base). Capital projects travel further - the maintenance patch is kept tight so the 4-hour emergency commitment is real, not aspirational.
What does a PPM contract cost?
A single-site commercial office typically runs £6,000-£15,000 per year depending on asset count; campus and multi-site portfolios run from £40,000 upward. Every Rossair PPM contract is priced bottom-up from the SFG20 task schedule against your actual asset list - never a flat per-square-metre rate - and the quote itemises what is Statutory, Mandatory and Optional so you can see exactly what you are buying.
Is an air conditioning maintenance contract part of PPM?
Yes. An air conditioning maintenance contract is usually one strand of a wider PPM agreement - biannual SFG20 servicing, F-Gas leak checks and TM44 inspections alongside the heating, ventilation, electrical and water-hygiene schedules. Single-service AC contracts are also available where that is all the building needs.
