Positive input ventilation (PIV) in Wimbledon
Loft or wall units that gently push filtered air into the home to tackle condensation. Covering Wimbledon and SW17, SW19 and SW20.
- From £950 inc VAT per home
- Free survey
PIV can suit Wimbledon houses and flats because it treats the whole home from one quiet unit.
We cover Wimbledon and the surrounding SW17, SW19 and SW20 postcodes as part of our work across Greater London. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

PIV for Wimbledon homes
It does not replace extract fans: kitchens and bathrooms still need their own extract to remove steam at source. On survey we check the loft, the landing position and the existing fans, and we tell you if PIV is not the right answer.
Heated PIV
A heater module tempers the incoming air in cold weather. Useful in homes where people feel draughts.
Wall-mounted PIV for flats
Draws air from outside through an outside wall. Suits flats and homes with no loft space.

Rules that apply in England

Questions from Wimbledon
Is the survey free in Wimbledon?
For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.
Will PIV make my house cold?
Most units temper or reduce the flow when the incoming air is cold, and a heated unit warms it. Placed correctly on the landing, the air spreads gently rather than blowing on anyone.
Can PIV be fitted in a flat?
Yes. Flats without loft space use a wall-mounted PIV unit that draws air from outside through an outside wall.
