How we approach MVHR servicing in Grays
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.

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.

Do you cover Grays and nearby?
Yes. We cover Grays and nearby places including Chafford Hundred, Tilbury, Swanscombe and South Ockendon. Send your postcode and we will confirm.
Do I need to be at home for the service?
Someone needs to let us in and be there when we measure the valves, which means visiting every room. A service usually takes one to two hours.
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.
