What MVHR servicing and filter changes involves

MVHR is often fitted and then forgotten. 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.

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.

Questions about MVHR servicing and filter changes in Oxfordshire

Is the survey free in Oxfordshire?

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.

My new build MVHR has never been serviced. Is that a problem?

It is very common and usually fixable. Builders often hand over without explaining filter changes, so the first service often finds filters that are badly blocked. We clean everything and reset the airflows.

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.

Which rules apply to ventilation in Oxfordshire?

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.

Which towns in Oxfordshire do you cover?

All of Oxfordshire, including Bicester, Didcot, Witney, Cowley and Carterton. If your town is not listed, send the postcode and we will confirm.
