Professional ventilation servicing and certificates for London landlords and property managers.

Ventilation systems are there for a reason.
When they are neglected, moisture builds up, airflow drops and condensation starts damaging the property from the inside. What starts as a £150 service becomes a £1,500–£3,000 emergency replacement.
Regular maintenance keeps your ventilation systems running efficiently, prevents property damage, and protects your investment.
No subcontractors. No middlemen. Our NICEIC-certified technicians handle everything, from installation and commissioning to filter cleaning, servicing, repairs and compliance certificates, giving you complete consistency and accountability on every job.
Managing multiple properties? We offer better rates for blocks and multi-unit buildings. The more units you need serviced, the lower the per-unit cost.
We focus on keeping existing systems working properly for longer. Regular maintenance now saves you thousands in replacements later.
Regular servicing and maintenance helps keep your system working properly and protects the property long term.





















Proper airflow helps remove moisture before it turns into damp, mould and property damage.
Regular servicing and filter maintenance can help ventilation systems last 15 years or more.
Clean filters and properly maintained systems help remove stale air and improve indoor comfort.
Preventative maintenance is usually far cheaper than replacing failed ventilation systems later on.
VentX was founded by professionals with nearly a decade of construction experience who saw the damage neglected ventilation systems cause firsthand.
Today we work with landlords and management companies across London — from single properties to large portfolio blocks, keeping ventilation systems compliant and preventing expensive failures.
