Protect your investment with professional maintenance


13 December 2023

The Chartered Institution of Building Services Engineers (CIBSE) recently updated its guide to Maintenance Engineering and Management.  Mark Richardson, General Manager at Batchelor Air Conditioning and Refrigeration, discusses the importance of choosing the right contract and contractor.

Widely viewed as an invaluable resource for anyone working in building services, Guide M is based on industry best practice. This third edition once again highlights the importance of professional maintenance, alongside the responsibilities of building operators.

Whatever the age of your air conditioning, HVAC or refrigeration system, the simple truth is that it needs looking after. Energy-efficient equipment can only remain that way for so long without the benefit of professional maintenance.

Most rational people would not splash out on an expensive car and then try recoup some of the cost by skipping major service intervals. Your system is also a significant investment, so it makes sense to take care of it. A regular maintenance programme also means that potential problems can often be identified and resolved before they have a serious impact on your business, in addition to adhering to legal requirements such as leak checking and system labelling.

The CIBSE guide identifies a variety of contract options available to building operators, including Planned Preventative Maintenance and Inspection and Maintenance options.

Planned Preventative Maintenance

Often referred to as PPM, this type of contract involves the provider conducting service tasks as part of an agreed plan or programme. The intention is that correct completion of this programme will minimise the risk of loss of service from the plant and optimise its economic life. Maintenance tasks for a PPM contract should be both site and usage specific.

For a fixed sum, the service provider will visit a site and look at the item of plant to confirm if it is working correctly. If the plant can have any maintenance conducted on it (such as topping up oil, checking filters, etc.), this is also completed, with materials charged as additional costs. Any work of a more specific nature or any repair will have an extra cost associated with it. CIBSE adds that the choice of service provider should be influenced by their experience and familiarity with the specific plant.

Choosing your contract

The guide authors point out that choosing the correct maintenance contract can be affected by factors including:

  • The client’s own in-house capabilities
  • The future property/estate strategy
  • The level of funding available
