Most of West Yorkshire is supplied with soft water. Even so, condensation is the bigger problem in any bathroom, and a properly sized extractor is what deals with it. Hardness varies street by street, so check the figure for your postcode with your water supplier. In Leeds flats, a new vent through an outside wall may need freeholder consent, so we raise it at the survey.

What the job includes

• A fan chosen to meet the bathroom extract rate: 15 l/s intermittent or 8 l/s continuous
• Wiring by a qualified electrician, with an isolator outside the room and RCD protection
• 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
• Core-drilling through the wall, or ducting through the loft to a roof or soffit vent
• A backdraught shutter and external grille, so cold air does not blow back in

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.

Intermittent or continuous

An intermittent fan runs during and after use. A continuous fan runs quietly all the time at a low rate and boosts when humidity rises.

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.

Noise

Compare the stated noise level in decibels. Inline fans and low-speed continuous fans are much quieter in the room than budget axial fans.

Rules that apply in England

A bathroom needs extract ventilation when it is newly formed, and on a refit an existing fan should not be replaced with a less effective one. The fan and its wiring must meet BS 7671 for the zone it sits in, on a circuit with 30 mA RCD protection. In a flat, the lease often requires freeholder consent for a new extract vent, and in a listed building a new opening through an external wall can need listed building consent.

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.
