Working in Sevenoaks
We work right across Sevenoaks — TN13 — and in neighbouring Tonbridge and Swanley.
Homes in and around Sevenoaks vary, so we look at the floor, the walls and the water system before we price anything. Where your Sevenoaks home already has a WC on gravity drainage, a macerator opens up more places a new cloakroom can go. If your Sevenoaks cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Most of Kent has very hard water. Taps, plug wastes and toilet pans scale up quickly, so chrome copes better than matt black, and a removable aerator is worth having. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A survey that checks the headroom under the stairs, the door swing and how the waste will reach the drain
- A concealed cistern frame or WC unit where the space allows
- Splashback or feature tiling and a new floor, often LVT or porcelain
- A new waste connection to the soil stack or drain, or a macerator where the rules allow it
Decisions to make first
Door
An outward-opening door is usually needed so it does not hit the WC. A sliding door suits a narrow hallway where an outward door would block the way.
Under-stair layout
Headroom drops quickly under stairs. The basin and the space in front of the WC need standing height; the low end of the room can take the cistern or storage.
Rules that apply in England
In England, a new WC connected to the soil stack or drain is drainage work under Part H, and a newly formed cloakroom without an opening window should have mechanical extract; Approved Document F gives 6 litres per second as the design rate for a WC, against 15 for a bathroom. Because a cloakroom has no bath or shower, adding a light to an existing circuit is not notifiable under Part P, but a new circuit is.
