Working in Worthing
In Worthing we cover BN11, BN12, BN13 and 1 more postcode districts; we also cover Lancing, 2.4 miles away, and Shoreham-by-Sea.
Worthing has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. If the only toilet in your Worthing home is upstairs, a cloakroom under the stairs or in the utility can save a lot of trips. If your Worthing cloakroom has no window, we size and duct the extractor fan so the room clears properly.
Water across much of West Sussex is hard. 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 concealed cistern frame or WC unit where the space allows
- Compact sanitaryware: a short-projection, back-to-wall or wall-hung WC and a corner, wall-hung or slim vanity basin
- Splashback or feature tiling and a new floor, often LVT or porcelain
- Lighting wired by a qualified electrician, tested and certified
Decisions to make first
Finishes
A small room can carry a bolder tile or wallpaper. A feature wall behind the WC costs far less here than in a full bathroom because there is so little of it.
Macerator or gravity
Gravity drainage is silent and needs no maintenance. A macerator lets a WC go where a pipe could not otherwise fall, provided another WC in the house is on gravity drainage.
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.
