MVHR often makes sense in Watford homes that have recently been insulated, re-windowed or made more airtight.
Whether the property is in the middle of Watford or one of the villages around it, the process is the same: a look at the building, a written price, then fitting and testing on the agreed day.

MVHR for Watford homes
Filters on both sides keep pollen and dust out of the house and keep the exchanger clean. MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway.
Retrofit in an occupied home
Ducts routed through the loft and down through cupboards or boxed corners. Most semis are done in 3 to 5 days.
New build or full renovation
Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

Rules that apply in England
In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.
Questions from Watford
Do you cover Watford and nearby?
Yes. We cover Watford and nearby places including West Watford, Bushey, North Watford and Croxley Green. Send your postcode and we will confirm.
Do I keep my trickle vents with MVHR?
No. Under Approved Document F, background ventilators should not be installed with a whole-home MVHR system, so we advise closing or removing them once the system is commissioned.
How often does MVHR need servicing?
Filters usually need changing every 6 to 12 months, and a full service with a clean and airflow check once a year keeps the system efficient. Clogged filters are the most common reason MVHR stops working properly.
