Frequently Asked Questions

What is the difference between PPM and Reactive Maintenance?

PPM (Planned Preventive Maintenance) is scheduled work intended to keep equipment working and prevent failure (e.g., an annual boiler service). Reactive Maintenance is fixing equipment after it has already broken down. A good strategy prioritises PPM to reduce the need for Reactive calls.

Do you offer maintenance for equipment you didn't install?

Yes. We can adopt your existing assets. We start with an asset verification survey to check the condition of your current systems and then build a maintenance schedule to suit them.

What are your emergency response times?

For contract clients, we adhere to strict Service Level Agreements (SLAs). For critical emergencies—such as a total loss of power, heating, or water—we typically target a 4-hour response. For non-urgent repairs, we schedule visits at a time that minimises disruption to your business operations.
