How we do it

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.

Filter supply

The right filters for your unit, ready to change yourself between visits.

Fault finding

Noisy fans, error codes, condensate leaks and boost controls that stopped working.

Annual service

Filters, exchanger and fan clean, drain check, controls and boost checked, airflow spot-checked at the valves.

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 Wiltshire

Is the survey free in Wiltshire?

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 Wiltshire?

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 Wiltshire do you cover?

All of Wiltshire, including Salisbury, Trowbridge, Chippenham, Melksham and Warminster. If your town is not listed, send the postcode and we will confirm.

If the system in your Wiltshire home needs more than a service, we will explain why and price it before doing anything.
