What the work involves

Ventilation that is not maintained slowly loses airflow, costs more to run and fails at the worst time. SFG20 schedules are widely used to set maintenance tasks and frequencies, and many insurers and landlords expect evidence that plant is serviced. Contracts range from two visits a year for a single unit to full multi-site schedules.

Combined compliance

TR19 cleaning and LEV testing on the same contract.
