What ventilation servicing and maintenance contracts 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.
Single-site contracts
Small offices, shops and clinics with one or two units.
Multi-site contracts
Portfolios and estates on one schedule and price list.
Combined compliance
TR19 cleaning and LEV testing on the same contract.
