What the work involves
Over a year or two the filters clog, the fans work harder, airflow at the valves drops and the house slowly goes back to condensation and stale air. It is common for a system to go years without a filter change after the builder hands over. A service puts that right.
Annual service
Filters, exchanger and fan clean, drain check, controls and boost checked, airflow spot-checked at the valves.
Rebalance and recommission
Every valve measured and set again to the design rates, with a new commissioning sheet. Useful after building work or if rooms feel stuffy.
Filter supply
The right filters for your unit, ready to change yourself between visits.

Rules in England
English building work follows Approved Document F (2021 edition) for ventilation rates, installation and commissioning. 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 about MVHR servicing and filter changes in Cornwall
Is the survey free in Cornwall?
This is a charged visit because it is servicing, testing or repair work. We tell you the cost before booking. Surveys for new installations on the UK mainland are free.
How much does an MVHR service cost?
An MVHR service usually costs £145 to £245 including VAT, depending on the unit and how easy it is to reach. Filters are included for most common units; rebalancing every valve is priced separately at £245 to £445.
How often should MVHR filters be changed?
Most manufacturers recommend changing MVHR filters every 6 to 12 months, and more often near busy roads or building sites. A full service once a year is a sensible minimum.
Which rules apply to ventilation in Cornwall?
In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
