How often should my air ducts be cleaned?
The recommended frequency for air duct cleaning in commercial buildings depends on your facility type, ventilation load, and environmental factors. In general:
- High-use environments (e.g. commercial kitchens, hospitals): every 6 to 12 months
- Moderate-use spaces (e.g. offices, schools, retail): every 12 to 18 months
- Low-use or low-occupancy areas: every 2 to 3 years, with regular inspections
Regular air duct cleaning helps improve indoor air quality, maintain HVAC efficiency, and support health and safety compliance.

What areas of a kitchen do you deep clean?
Our kitchen deep cleaning service covers:
- Cooking equipment (ovens, fryers, grills, hobs)
- Walls, floors, ceilings
- High-touch and hard-to-reach areas
- Under and behind equipment
- Prep surfaces and splashbacks
This helps reduce contamination risks, ensures hygiene compliance, and keeps your kitchen in top condition.
I only run a small café in Bristol, do I really need proper extraction cleaning?
Yes. Even small cafés produce grease and airborne particles that build up in ductwork over time. If your café uses grills, fryers, or ovens, you must comply with TR19 hygiene standards. Regular extraction cleaning helps you avoid fire risks and meet EHO requirements.
What is included in a TR19 cleaning certificate?
A TR19 certificate includes:
- Confirmation of service scope
- Visual before-and-after photos
- A detailed maintenance report
- Cleaning schedule recommendations: This documentation is essential for insurance compliance, audits, and fire safety assessments.
Do I need ESP maintenance if I already get extraction cleaning?
Yes. ESPs (Electrostatic Precipitators) are pre-filtration units that trap grease before it reaches the ductwork. Without regular ESP maintenance, these systems can become blocked, reduce airflow, and increase fire risk.
Pairing ESP servicing with extraction cleaning ensures full system performance.
What happens if I don't clean my extraction system?
Failure to maintain your kitchen extraction system can result in:
- Increased fire hazards from grease build-up
- Insurance claims being denied
- EHO penalties or kitchen closures
- Unpleasant odours and poor airflow
