Working in Winchester
In Winchester we cover SO21, SO22 and SO23; we also cover Eastleigh, 6.9 miles away, and Romsey.
In a city the size of Winchester, parking and access for a skip are worth sorting before the start date — we will ask at the survey. In Winchester flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey. If your Winchester home is listed or in a period terrace, a fan ducted through the loft to a roof vent can avoid a new hole in the front wall, though consent may still apply.
Supplies across most of Hampshire are hard. Steam carries that scale onto mirrors and glass, so a fan that clears the room quickly helps on both counts. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
- Making good around the fan and checking that it extracts properly at the grille
- Rigid or semi-rigid ducting kept short and straight, and insulated where it crosses a cold loft
- A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
Decisions to make first
Timer or humidistat
A timer keeps the fan running after the light goes off. A humidistat starts it whenever moisture rises, which suits rooms where people forget.
Wall or ceiling
A wall fan on an outside wall is the simplest. A ceiling fan over the shower takes steam away at source but needs ducting through the loft.
Rules that apply in England
In England, Approved Document F sets bathroom extract at 15 l/s for an intermittent fan or 8 l/s for continuous extract. Wiring a new fan alters a circuit in a room with a bath or shower, so it is notifiable under Part P.
