MVHR servicing and filter changes in Merseyside

Many Merseyside new builds have MVHR in the loft that nobody told the owners how to look after.

Merseyside has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

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.

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.

Fault finding

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

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.

Which towns in Merseyside do you cover?

All of Merseyside, including Birkenhead, St Helens, Southport, Wallasey and Bootle. If your town is not listed, send the postcode and we will confirm.

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.

Are prices different in Merseyside?

Our guide prices are adjusted by region. In Merseyside we use North West rates, so MVHR service: filters, unit and heat exchanger clean, airflow check is typically £140 to £235 inc VAT per visit.
