Working in Tonbridge
We work right across Tonbridge — TN9, TN10 and TN11 — and in neighbouring Tunbridge Wells and Sevenoaks.
In Tonbridge, as anywhere, the age of the house decides a lot: pipe sizes, floor construction and where the soil stack runs. If your Tonbridge 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. Fans fitted in Tonbridge bathrooms are wired by a qualified electrician, with RCD protection and an isolator outside the room.
Most of Kent has very hard water. 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
- Run-on timer, humidistat or light-linked switching set up to suit how the room is used
- A backdraught shutter and external grille, so cold air does not blow back in
- A check of the room, any existing fan or vent, and the shortest route to the outside
- Making good around the fan and checking that it extracts properly at the grille
Decisions to make first
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.
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.
