Ventilation System Servicing Across London
Ventilation systems that aren’t regularly serviced lose efficiency, block with particulates, and — critically for London properties — stop removing the moisture that causes condensation and mould. We service MVHR, PIV, and extractor fan systems across London with fixed prices and written reports on completion.
Why servicing matters
What Happens When a Ventilation System Isn’t Serviced
In London’s higher-particulate environment, ventilation systems block faster than in rural areas. An unserviced system doesn’t just underperform — it actively contributes to the moisture and air quality problems it was installed to prevent.
Blocked filters cause condensation
When an MVHR or PIV system can’t move air effectively, moisture accumulates on walls and windows — leading to the condensation and mould growth the system was installed to prevent.
Dirty systems recirculate contaminants
Filters clogged with dust, pollen, and pollutants no longer clean incoming air — they reintroduce particulates into the living space. Particularly significant for allergy sufferers and children.
MVHR efficiency degrades without cleaning
A heat exchanger coated in dust loses its heat recovery capacity — increasing running costs and negating the energy savings the system was designed to deliver.
Noise increases as systems strain
Motors working against blocked filters or poorly commissioned airflow run louder and wear faster. Regular servicing keeps systems running quietly within specified operating parameters.
Systems we service
Ventilation Servicing Services in London
We service all three main residential ventilation system types. A survey visit establishes your system’s manufacturer, model, installation configuration, and the appropriate service scope before any work is quoted.
MVHR Servicing London
Mechanical Ventilation with Heat Recovery systems require annual servicing to maintain heat recovery efficiency and indoor air quality. We service all major MVHR brands and offer three package tiers.
- Supply and extract filter replacement
- Heat exchanger cleaning
- Room air valve cleaning and sanitising
- Unit and motor inspection and cleaning
- Airflow recommissioning to spec
- Written service report on completion
PIV Servicing London
Positive Input Ventilation units — including Vent-Axia and equivalent systems — require periodic filter replacement and inspection to maintain performance. A blocked PIV filter significantly reduces the unit’s ability to manage condensation.
- Filter replacement (Vent-Axia and all brands)
- Unit inspection and external cleaning
- Installation integrity check
- Loft-mounted unit access included
- Performance verification post-service
- Written report on completion
Extractor Fan Servicing
Bathroom, kitchen, and utility room extractor fans collect dust and grease over time, reducing airflow and increasing motor strain. Annual cleaning maintains extract rates and extends unit lifespan.
- Cover and grille removal and cleaning
- Fan blade and motor housing cleaning
- Ductwork outlet inspection
- Motor performance check
- Refit and airflow verification
- Replacement recommended where unit is beyond service life
Ventilation Survey
Not sure what system you have, or whether your ventilation is adequate? A survey establishes the system type, condition, and service requirements — and identifies whether a new installation is needed rather than a service.
- System identification (manufacturer, model, age)
- Current performance assessment
- Condensation and air quality review
- Written report with recommendations
- Fixed service quote on completion
Not sure which service your system needs?
Call us and describe what you have — make, model, or where it’s installed. We can advise on what’s required before booking a visit, and confirm pricing upfront.

Don’t Let a Blocked Ventilation System Cause Mould
An unserviced MVHR or PIV system fails to remove moisture — and that moisture turns into condensation, damp, and mould. Annual servicing is the most cost-effective prevention.
