Ventilation installation in Leeds

Shared houses and busy bathrooms

A student house in Hyde Park or Headingley may have five people showering in one bathroom each morning. A weak fan on a light switch can't keep up. Building Regulations guidance sets minimum extract rates for kitchens and bathrooms, and a humidistat fan that runs until the room dries is worth the small extra cost.

Check the fan actually vents outside. In old terraces it's not unusual to find one ducted into the loft.

PIV for older houses

Positive input ventilation pushes filtered air from the loft into the landing, which forces damp air out through gaps and trickle vents. It suits two-storey houses with a loft and a central stairwell, like many Leeds semis and through terraces. It doesn't suit back-to-backs with a converted attic and nowhere to fit the unit.

MVHR in newer flats

Many recent blocks have mechanical ventilation with heat recovery. The filters need changing, usually once or twice a year, and if they clog the system slows and the flat gets stuffy. If you're renting, ask the landlord when they were last done.

Ventilation in a heatwave

When Bramham hit 39.8°C in 2022, flats that couldn't open windows at night suffered most. MVHR with a summer bypass helps a little by not heating incoming air, but it isn't cooling. Look at shading first.
