Ventilation installation in Leicester
Extractor fans, positive input ventilation and whole-house systems, passed to installers who cover your Leicester postcode.
Old houses used to breathe through gaps: open fireplaces, loose sash windows and draughty floors. Leicester has a quarter of its homes from before 1919, and most have since had their chimneys capped, uPVC windows fitted and floors sealed. Moisture from cooking, showers and drying clothes now has nowhere to go.
The fix is to give it a controlled way out, rather than opening the leaks again.

Kitchen and bathroom fans first
A fan that ducts outside, sized for the room and left on for 15 minutes after a shower, removes moisture at source. Approved Document F sets minimum extract rates for kitchens and bathrooms in new work. Many older fans fitted in terraces are too small or vent into the loft, which moves the problem rather than solving it.
Humidity-controlled fans switch on by themselves, which helps in rented homes where nobody remembers the switch.
Positive input ventilation
A PIV unit sits in the loft and pushes filtered air gently into the landing. It suits two-storey terraces and semis with condensation on bedroom windows. It costs little to run but can make a house feel slightly cooler in winter.
It is less suited to flats without a loft, where a wall-mounted version is needed.
MVHR
Mechanical ventilation with heat recovery suits airtight new builds and deep retrofits. It is rarely practical to add to an occupied Victorian house because of the ducting it needs. Leicester's Warm Homes: Local Grant can fund ventilation alongside insulation when the installer finds it is needed.
Leicester homes and what they need
Red-brick Victorian terraces
Back-addition bathrooms with an outside wall are easy to vent. Rear kitchens often have a cooker hood that recirculates; swap it for one that ducts out.
Interwar and postwar semis
Bathrooms squeezed into a former box room often have no outside wall for a fan. A ducted fan through the loft to a roof or soffit vent solves it.
Estates built from the 1990s onwards
Trickle vents in the window frames are often taped shut. Open them and clean the fans before buying anything new.
Areas covered
Engineers who cover Leicester work across areas including Clarendon Park, Stoneygate, Knighton, Belgrave, Evington, Aylestone, Braunstone, Oadby, Wigston and Birstall.
Questions people in Leicester ask
Will a dehumidifier do the same job?
It helps in one room, but it treats the symptom. Fans and PIV remove damp air before it reaches cold walls. The difference is explained in our window condensation guide.
Do I need a fan in a rented flat?
Ask your landlord. A working extractor in the kitchen and bathroom is one of the first things a council housing officer checks when tenants report condensation.
