Keeping Buildings Compliant Over the Christmas Shutdown

Many commercial buildings operate at low or no occupancy over Christmas. While this may be operationally convenient, it also creates elevated compliance risks. Water stagnation can encourage Legionella bacteria, dormant kitchen extract ductwork can remain at or above TR19 Grease thresholds, and reduced ventilation operation may impact indoor air quality under TR19 Air.

Key Compliance Areas to Review During the Christmas Shutdown

Legionella

When outlets are unused, temperatures may drift into the risk range. Before shutdown, confirm temperatures, review the written scheme, and run outlets. During closure, maintain temperature controls and, where possible, schedule periodic flushing. When reopening, flush outlets and confirm sentinel temperatures to evidence compliance.

TR19 Grease

Grease deposits remain a fire risk even when the kitchen is closed. If the system is approaching TR19 Grease thresholds, schedule inspection or cleaning before shutdown. Ensure canopies, ductwork and fans meet the required hygiene classifications and retain documentation for insurance purposes.

TR19 Air

Reduced HVAC operation can allow particulate build-up and poor indoor air quality on return. Conduct condition checks before shutdown and it can be a good idea to plan TR19 Air cleaning or filter replacement early in the new year.

Preparing for January

Focusing on these three areas ensures buildings reopen safely, with compliant water systems, fire-safe extraction, and healthy ventilation. Planning inspections and maintenance before and immediately after the break provides clear evidence of compliance and mitigates seasonal risk.
